General Information and System Description

Introduction

The Agras T40 and Agras T20P have a truss-style design with arms that can be folded to reduce

the body size, making the aircraft easier to transport. The all-new integrated spraying system can

quickly be swapped with a spreading system. The spreading payload of the T40 has increased to

50 kg for more efcient spreading.

The spatial intelligent sensing system includes active phased array radars and binocular vision

to ensure ight safety. Boasting a 12MP UHD FPV camera with a tiltable gimbal, the aircraft can

automatically collect HD field images for local offline reconstruction to assist in precise field

planning. Using the P4 Multispectral and DJI Agras Intelligent Cloud, prescription maps can be

generated in order to perform variable rate fertilization.

The spraying system is equipped with the brand new magnetic drive impeller pumps, dual atomized

sprinklers, and anti-drip centrifugal valves. When used with the weight sensors, the spraying

system provides real-time liquid level detection and improves spraying efciency while saving liquid

pesticide.

Core modules adopt potting technology and the aircraft has a protection rating of IPX6K (ISO

20653:2013) so that the aircraft body can be washed directly with water.

The next generation DJI RC Plus remote controller features DJI O3 Agras, the latest version of the

signature OCUSYNC

image transmission technology, and has a max transmission distance of

up to 7 km (at an altitude of 2.5 m).

[1]

The remote controller has a high-performance 8-core CPU

and a built-in 7-in high brightness touchscreen powered by the Android operating system. Users

can connect to the internet via Wi- Fi or the DJI Cellular Dongle. Operations are more convenient

and accurate than ever before thanks to the revamped DJI Agras app design and a wide range of

buttons on the remote controller. With Mapping mode added to the app, users can complete ofine

reconstructions and perform precise eld planning without the need of extra devices. The remote

controller has a maximum operating time of 3 hours and 18 min with the high-capacity internal

battery. Users can also purchase an external battery separately to be used to supply power to the

remote controller and fully meet the requirements for long and high-intensity operations.

[1] The remote controller is able to reach its maximum transmission distance (FCC/NCC: 7 km (4.35 mi);

SRRC: 5 km (3.11 mi); CE/KCC/MIC: 4 km (2.49 mi)) in an open area with no electromagnetic interference, and

at an altitude of approximately 2.5 m (8.2f t).

Aircraft

Feature Highlights

The aircraft has a truss-style body with arms that can be quickly folded, making it easy for

transportation. Folding detection sensors built into the frame arms enable the aircraft to perform

a folding mechanism self-check, ensuring the arms are properly unfolded. The aircraft supports

centimeter-level positioning

[1]

when used with the onboard D-RTK

Thanks to the spatial intelligent sensing system with the binocular vision system, active phased

array omnidirectional radar, and active phased array backward and downward radar, the aircraft

can achieve comprehensive obstacle sensing and terrain following to ensure ight safety as well as

improve operation efciency.

In the new Mapping operation mode, images in the task area can be captured using the UHD FPV

camera, and local maps can be generated using the remote controller without internet connection

to assist in precise planning.

In the new Fruit Tree operation mode, operations imported in multiple methods can be displayed

together for users to start operations more efciently.

The dual atomized spraying system is equipped with the brand new magnetic drive impeller

pump, making the system more corrosion-resistant and durable. The dual atomized sprinkler

and proprietary centrifugal valve prevent leakage and reduce pesticide use while protecting the

environment.

The T40 aircraft is equipped with a coaxial twin-rotor structure to produce strong winds so that

pesticides can penetrate thick canopies for thorough spraying.

Aircraft and operation control is more convenient than ever, thanks to a wide range of buttons and

dials on the DJI RC Plus remote controller. With the built-in revamped DJI Agras app, the payload

for each ight is maximized through intelligent route planning for greater efciency.

possibilities.

Binocular Vision and Phased Array Radar (Detection and Obstacle Avoidance System)

Prole

The aircraft spatial intelligent sensing system consists of the binocular vision system, active phased array

omnidirectional radar, and active phased array backward and downward radar. In an optimal operating

environment, the radar module can predict the distance between the aircraft and the vegetation or other

surfaces in forward, backward, and downward directions to y at a constant distance and ensure even

spraying and terrain following. The system can detect obstacles in all horizontal directions as well as

upward and backward to ensure ight safety. In addition, the ight control system limits the descent

speed of the aircraft according to the distance between the aircraft and ground detected by the radar

modules to achieve a smooth landing.

AGRAS T40/T20 P

Unmanned Aircraft Flight Manual

The binocular vision system is enabled automatically when the aircraft is in use. Terrain follow and

bypassing functions need to be enabled in the app before use. In Route and A-B Route operation

modes, users can enable the terrain follow and bypassing functions for different terrain types. The

aircraft will y above the vegetation at a constant spraying distance and bypass detected obstacles.

When task terrain is set to Mapping/Field on Flatland, bypassing can be enabled or disabled

independently. In Manual Plus and Mapping operation modes, select Mapping/Field on Flatland as the

task terrain and enable Auto Terrain Follow. The aircraft will achieve terrain follow. In Manual and Fruit

Tree operation modes, the radar can measure the spraying distance above the vegetation or other

surfaces, but the aircraft will not use the data for altitude stabilization. Obstacle avoidance can be used

in any mode.

Detection Range

Binocular vision system: 90° (horizontal), 106° (vertical), 0.4-25 m.

Active phased array omnidirectional radar: 360° (horizontal), ±45° (vertical), 1.5-50 m.

Active phased array backward and downward radar: ±60° (horizontal), ±25° (vertical), 1.5-30 m

(backward), 1-45 m (downward).

Note that the aircraft cannot sense obstacles that are not within its detection range. Fly with caution.

Detection Range of Binocular Vision System and Radars (Vertical)

45°

28°

25°

45°

106°

The effective detection range varies depending on the size and material of the obstacle. When

sensing objects such as buildings that have a radar cross section (RCS) of more than -5

dBsm, the effective detection range is 50 m. When sensing objects such as power lines that

have a RCS of -10 dBsm, the effective detection range is approximately 30 m. When sensing

objects such as dry tree branches that have a RCS of -15 dBsm, the effective detection range

is approximately 20 m. Obstacle sensing may be affected or unavailable in areas outside of

the effective detection distance.

Fly with caution when the aircraft is near an obstacle that is at a similar altitude with the bottom

of the aircraft. The aircraft cannot detect the obstacle as most or even the whole obstacle is

out of the detection range.

Horizontal Obstacle Avoidance Usage

Make sure horizontal and backward obstacle avoidance are enabled in the app. Obstacle avoidance is

used in the following two scenarios:

1. The aircraft begins to decelerate when it detects an obstacle 15 m in front of the aircraft (when the

aircraft is ying forward) or 15 m behind the aircraft (when the aircraft is ying backward), then brakes

and hovers. While braking, the aircraft cannot accelerate toward the obstacle but can y away from it.

AGRAS T40/T20 P

Unmanned Aircraft Flight Manual

2. The aircraft immediately brakes and hovers if it detects an obstacle nearby. Users cannot control the

aircraft while it is braking.

Users can y in a direction away from the obstacle to regain full control of the aircraft.

Backward obstacle avoidance will be disabled when the aircraft ies backward at a speed of

more than 7 m/s. Fly with caution.

Obstacle avoidance is disabled during auto landing. Make sure to operate the aircraft with

caution when controlling the aircraft manually during auto landing.

If backward obstacle avoidance is disabled in the app, the aircraft cannot detect obstacles

behind the aircraft while ying backward.

Upward Radar Usage

Make sure the upward obstacle avoidance function of the radar module is enabled in the app. Obstacle

avoidance is used in the following two scenarios:

1. The aircraft begins to decelerate when it detects an obstacle is 3 m away and brakes and hovers in

place.

2. The aircraft immediately brakes if it detects an obstacle nearby.

Users cannot accelerate in the direction of the obstacle, but can y in a direction away from the obstacle

when the aircraft is braking or hovering.

Terrain Follow and Bypassing Functions Usage

In Sensor Settings in the app, select the task terrain according to the environment and enable Auto

Terrain Follow and Obstacle Bypassing. Each type of task terrain is suitable for the corresponding

operation modes. Refer to the descriptions below.

Bypassing is disabled during night or in dark environments. Fly with caution.

In some scenarios such as with power lines, the bypassing function may not be able to

bypass the obstacle successfully. Users can bypass the obstacle by manually controlling the

aircraft.

Terrain follow will be affected when the aircraft is ying over water. Fly with caution.

The max ight speed of the aircraft will be limited to 7 m/s and the height above the vegetation

will be limited from 2.5 to 8 m when obstacle bypassing is enabled.

Mapping/Field on Flatland

This task terrain is suitable for Mapping operations or Route, A-B Route, and Manual operations in areas

without obvious surface elevation changes.

1. Select Mapping/Field on Flatland as the task terrain.

2. Enable Auto Terrain Follow only. Enter the desired operation mode and set the height above the

vegetation. After the operation is started, the aircraft will y above the vegetation at the pre-set height.

3. Enable both Auto Terrain Follow and Obstacle Bypassing (supporting Route and A-B Route

operations only). After a Route or A-B Route operation is started, the aircraft will bypass detected

obstacles automatically. Moving the control stick can pause auto bypassing. The aircraft will hover in

place if bypassing fails. Users can bypass the obstacle by manually controlling the aircraft.

AGRAS T40/T20 P

Unmanned Aircraft Flight Manual

Fruit Orchard on Flatland and Mountain Land

Both Fruit Orchard on Flatland and Mountain Land are suitable for Route and A-B Route operations. Fruit

Orchard on Flatland is suitable for terrain without obvious surface elevation changes. Mountain Land

is suitable for undulating terrain covered with mountain crops and fruit trees. Flying vertically to bypass

obstacles takes priority in Mountain Land mode. Both modes have the same operation instructions.

1. Select the corresponding task terrain.

2. Enable Terrain Follow and Obstacle Bypassing. After a Route or A-B Route operation is started,

the aircraft will fly above the vegetation at the pre-set height and bypass detected obstacles

automatically. Moving the control stick can pause auto bypassing. The aircraft will hover in place if

bypassing fails. Users can bypass the obstacle by manually controlling the aircraft.

Radar Usage Notice

DO NOT touch or let your hands or body come in contact with the metal parts of the radar

module when powering on or immediately after ight as they may be hot.

Maintain full control of the aircraft at all times and do not rely completely on the radar module

and DJI Agras app. Keep the aircraft within VLOS at all times. Use your discretion to operate

the aircraft manually to avoid obstacles.

In Manual operation mode, users have complete control of the aircraft. Pay attention to the

ying speed and direction when operating. Be aware of the surrounding environment and

avoid the blind spots of the radar module.

The obstacle avoidance functions are disabled in Attitude mode.

When sensing objects such as an inclined line, inclined utility pole, or power line at an inclined

angle against the ying direction of the aircraft, the radar detection performance will be

affected since most of the radar electromagnetic waves are reected to other directions. Fly

with caution.

The radar module enables the aircraft to maintain a xed distance from vegetation only within

its working range. Observe the aircraft’s distance from vegetation at all times.

Operate with extra caution when ying over inclined surfaces. The recommended maximum

inclination at different aircraft speeds are 10° at 1 m/s, 6° at 3 m/s, and 3° at 5 m/s.

Comply with local radio transmission laws and regulations.

The sensitivity of the radar module may be reduced when operating several aircraft within a

short distance. Operate with caution.

The radar module is a precision instrument. DO NOT squeeze, tap, or hit the radar module.

Before use, make sure that the radar module is clean and the outer protective cover is not

cracked, chipped, sunken, or misshapen.

Keep the protective cover of the radar module clean. Clean the surface with a soft damp cloth

and air dry before using again.

AGRAS T40/T20 P

Unmanned Aircraft Flight Manual

Binocular Vision System Usage Notice

The performance of the binocular vision system is affected by light intensity and the patterns

or texture of the surface being flown over. Operate the aircraft with great caution in the

following situations:

a. Flying over monochrome surfaces (e.g., pure black, pure white, pure green).

b. Flying over highly reective surfaces.

c. Flying over water or transparent surfaces.

d. Flying in an area where the lighting changes frequently or drastically.

e. Flying over extremely dark (< 10 lux) or bright (> 10,000 lux) surfaces.

f. Flying over surfaces with repeating identical patterns or textures or with particularly sparse

patterns or textures.

Keep the cameras of the binocular vision system clean at all times.

Make sure that there are clear patterns and adequate lighting in the surroundings since

the binocular vision system relies on images of the surrounding environment to obtain

displacement data.

The obstacle sensing function of the binocular vision system may not work properly when the

aircraft is operated in a dim environment or over water or surfaces without a clear pattern.

Keep the cameras of the binocular vision system clean. Make sure that the aircraft is powered

off. First remove any larger pieces of grit or sand then wipe the lens with a clean, soft cloth to

remove dust or other dirt.

Normal Procedures

Airspace Environment

The DJI Agras T40/T20P is a multi-copter crop protection RPAS mainly operated in farming, forestry,

animal husbandry and shery scenarios. Once pre-ight preparation is complete, it is recommended to

hone your ight skills and practice ying safely. Make sure that all ights are carried out in an open area.

Operation Environment

1. To avoid injury and damage and make sure spraying is effective, spray in winds lower than 6 m/s. It

is recommended to spray in winds lower than 3 m/s for herbicides, fungicides, and insecticides that

may drift and cause phytotoxicity and can be poisoning.

2. DO NOT use the aircraft in adverse weather conditions such as winds exceeding 6 m/s, rain, snow,

or fog.

3. Only y in open areas. Tall buildings and steel structures may affect the accuracy of the compass

and the GNSS signal.

4. Pay attention to utility poles, power lines, and other obstacles. DO NOT fly near or above water,

people, or animals.

5. Maintain VLOS of the aircraft at all times, and avoid flying near obstacles, crowds, animals, and

bodies of water.

6. Avoid ying in areas with high levels of electromagnetism, including mobile phone base stations and

radio transmission towers.

7. DO NOT y more than 4500 m above sea level.

8. The DJI Agras app will intelligently recommend the payload weight limit for the tank according to the

current status and surroundings of the aircraft. Do not exceed the recommended payload weight

limit when adding material to the tank. Otherwise, the ight safety may be affected.

9. Make sure that there is a strong GNSS signal and the D-RTK antennas are unobstructed during

operation.

10. DO NOT operate the aircraft indoors.

GEO (Geospatial Environment Online) System

GEO Zones

DJI’s GEO System designates safe flight locations, provides risk levels and safety concerns for

individual ights, and offers restricted airspace information. The locations designated by GEO are

called GEO Zones. GEO Zones are specic ight areas that are categorized by ight regulations and

restrictions. GEO Zones that prohibit ight are implemented around locations such as airports, power

plants, and prisons. They can also be temporarily implemented around major stadium events, forest

res, or other emergency situations. Certain GEO Zones do not prohibit ight but do trigger warnings

informing users of potential risks. All restricted ight areas are referred to as GEO Zones, and are

further divided into Warning Zones, Enhanced Warning Zones, Authorization Zones, Altitude Zones,

and Restricted Zones. By default, GEO limits ights into or taking off within zones that may result in

safety or security concerns. There is a GEO Zone Map, which contains comprehensive global GEO

Zone information on the ofcial DJI website: https://www.dji.com/ysafe.

The GEO System is for advisory purposes only. Individual users are responsible for checking ofcial

sources and determining which laws or regulations may apply to their ight. In some instances, DJI

has selected widely-recommended general parameters (such as a 1.5-mile radius at airports) without

making any determination as to whether these guidelines match regulations that apply to specic users.

Warning Zones:

Users receive a warning message with information relevant to their ight.

Enhanced Warning Zones:

Users receive a prompt from the GEO System at the time of ight. They are

required to conrm their ight path.

Authorization Zones:

Users receive a warning message and the flight is prohibited by default.

Authorization Zones can be unlocked by authorized users with a DJI-veried account. Self-Unlocking

privileges must be applied for online. https://www.dji.com/ysafe

Altitude Zones:

Flights are limited to a specic altitude.

permission to y in a Restricted Zone, please go to https://www.dji.com/ysafe or contact ysafe@dji.

com to unlock the zone.

DJI GEO Zones aim to ensure the user’s flight safety, but it cannot be guaranteed to be in full

compliance with local laws and regulations. Users should check local laws, regulations, and regulatory

requirements before each ight and are responsible for the ight safety.

All intelligent flight features will be affected when DJI aircraft fly nearby or into GEO Zones. Such

interference includes, but is not limited to, decreased speed, takeoff failure, and ight termination.

Flight Limits

Unmanned aerial vehicle (UAV) operators should abide by the regulations from self-regulatory

organizations such as the International Civil Aviation Organization, the Federal Aviation Administration,

and their local aviation authorities. For safety reasons, ight limits are enabled by default to help users

operate this aircraft safely and legally. Users can set ight limits on height and distance.

When operating with a strong GNSS signal, the height and distance limits and GEO zones work

together to monitor ight. With a weak GNSS signal, only the rmware height limit prevents the aircraft

from going above 100 meters.

Maximum Height and Radius Limits

Users can change the maximum height and radius limits in the app. Once completed, the aircraft ight

is restricted to a cylindrical area that is determined by these settings. The tables below show the details

of these limits.

AGRAS T40/T20 P

Unmanned Aircraft Flight Manual

With a strong GNSS signal

Flight Limits

Max Height Flight altitude must be below the preset height.

Max Radius Flight distance must be within the max radius.

With a weak GNSS signal

Max Height Flight altitude must be below the preset height.

Max Radius No limit.

If the aircraft ies into a Restricted Zone, it can still be controlled, but the aircraft can only y in

a backward direction.

If the aircraft loses GNSS signal and ies out of the max radius but regains GNSS signal later,

it will y back within range automatically.

DO NOT y near airports, highways, railway stations, railway lines, city centers, or other busy

areas. Make sure the aircraft is visible at all times.

GEO Zone Flight Restrictions

GEO Zone Description

1. Avoid using wireless devices that use the same frequency bands as the remote controller.

2. When using with multiple aircraft, including T40, T20P, and other aircraft, make sure that the distance

between each aircraft is more than 10 m to avoid interference.

3. The sensitivity of the radar module may be reduced when operating several aircraft within a short

distance. Operate with caution.

4. Be alert when flying near areas with magnetic or radio interference. These include, but are not

limited to, high voltage lines, large scale power transmission stations or mobile base stations, and

broadcasting towers. Failing to do so may compromise the transmission quality of this product or

cause transmission errors which may affect ight orientation and location accuracy. The aircraft may

behave abnormally or go out of control in areas with too much interference.

5. If the RTK dongle is used for eld planning, the module should be disconnected from the remote

controller after planning is completed. Otherwise, it will affect the communication performance of the

remote controller.

Operating the Aircraft

This section explains how to control the orientation of the aircraft through the remote controller. Control

can be set to Mode 1, Mode 2, or Mode 3. For example, the following description uses Mode 2:

AGRAS T40/T20 P

Unmanned Aircraft Flight Manual

Flight Modes

The aircraft will y in N-mode (Normal) by default. Users can switch between ight modes by toggling

the Flight Mode switch on the remote controller when A-mode is enabled in the app.

N-mode/F-mode (Normal):

The aircraft utilizes GNSS or the RTK module for positioning. When the

GNSS signal is strong, the aircraft uses GNSS for positioning. When the RTK module is enabled and the

differential data transmission is strong, it provides centimeter-level positioning. It will revert to A-mode

when the GNSS signal is weak or when the compass experiences interference.

S-mode (mapped to A-mode, Attitude):

GNSS is not used for positioning and the aircraft can only

maintain altitude using the barometer. The ight speed in A-mode depends on its surroundings such as

the wind speed.

Attitude Mode Warning

In A-mode, the aircraft cannot position itself and is easily affected by its surroundings, which may result

in horizontal shifting. Use the remote controller to position the aircraft.

Maneuvering the aircraft in A-mode can be difcult. Avoid ying in conned spaces or in areas where

the GNSS signal is weak. Otherwise, the aircraft will enter A-mode, leading to potential ight risks. Land

the aircraft in a safe place as soon as possible.

Emergency Procedures

General Information

This chapter introduces how to handle the aircraft or remote controller if one of the following

emergencies occurs.

Engine Failure

If one or more motors fail during ight, the aircraft will calculate the remaining propulsion according to

factors such as the status of the propulsion system, aircraft weight, and ight environment. Two possible

scenarios may occur:

1. Remaining propulsion is sufcient: the aircraft will continue to y in a stable condition with remaining

propulsion.

2. Remaining propulsion is insufcient: the aircraft will spin and perform a controlled descent.

Afterward, it is recommended that users land the aircraft manually and check and repair the aircraft

immediately.

Fire

A prompt will appear in the app and the flight controller will reduce the power of the aircraft when

the flight battery temperature is too high. The battery will be locked for future use if it exceeds the

temperature threshold during ight and cannot be used again after landing.

Follow the instructions below if the ight battery catches re.

1. If the battery catches re when the battery is being charged using a battery station or generator,

make sure personal safety is guaranteed, power off the battery station or generator immediately,

and disconnect the battery from the charging device. If the battery catches re when the battery is

in the aircraft, make sure personal safety is guaranteed and disconnect the battery from the aircraft

immediately.

2. Transfer the ammable materials surrounding the battery to a safe distance of more than 5 m away.

3. If the re is small, use materials such as large amount of sand to cover the location of the re and

pour cold water to cool the battery until there is no longer any smoke being produced. With the

help of re-resistant gloves or other protective tools that allow users to avoid direct contact with the

battery, move the battery to a container with enough water to fully immerse the battery and add an

appropriate amount of salt to help fully discharge the battery. Leave the container in a cool place for

more than 72 hours and take out the battery and discard it.

4. If the re is large, double check that there are no ammable materials surrounding the re, extend

the safety distance to more than 10 m, and evacuate any people in the surrounding environment.

Wait until the battery burns out and the re is extinguished in order to avoid any further accidents.

Loss of C2 Link

The aircraft supports Failsafe RTH function.

Home Point:

The default home point is the first location where your aircraft received strong

GNSS signals

. Note that the white GNSS icon requires at least four bars before the signal is

strong.

RTH:

RTH brings the aircraft back to the last recorded home point.

AGRAS T40/T20 P

Unmanned Aircraft Flight Manual

Failsafe RTH

The aircraft will RTH or hover if the remote controller signal is lost. The action can be set in the

app. Failsafe RTH will only be available if RTH is set.

Failsafe RTH is automatically activated if the remote controller signal is lost for more than three seconds,

provided that the home point has been successfully recorded, the GNSS signal is strong

, and the

RTK module is able to measure the heading of the aircraft. The RTH continues if the remote controller

signal is recovered, and users can control the aircraft using the remote controller. Press the RTH button

once to cancel RTH and regain control of the aircraft.

RTH Illustration

If RTH is triggered during Route operations, the aircraft can plan a flight path for RTH to

circumvent the obstacles added when planning a eld.

RTH Safety Notices

3 m

The aircraft will not enter RTH if RTH is triggered when the aircraft is within a 3m radius of

the Home Point, but the remote controller will still sound an alert. Exit RTH to cancel the

alert.

The aircraft cannot return to the home point when the GNSS signal is weak (the GNSS

icon displays red) or is unavailable.

Obstacle Avoidance During RTH

In an optimal operating environment, obstacle avoidance during RTH is available. If there is an obstacle

within 20 m of the aircraft, the aircraft decelerates and then stops and hovers. The aircraft will exit the

RTH procedure and wait for further commands.

Landing Protection Function

Landing Protection activates during auto landing. The procedure is as follows:

1. After arriving at the home point, the aircraft descends to a position 3 m above the ground and hovers.

2. Control the pitch and roll sticks to adjust the aircraft position and make sure the ground is suitable for

landing.

1. Record Home Point (HP)

4. RTH initiated if signal lost > 3 s

5. RTH initiated (height 15 m (customizable))

3. Remote controller signal lost 2. Conrm Home Point

6. Lands after hovering for 5 s

Height over HP > 15 m

Elevate to 15 m

Height over HP ≤ 15 m

15 m

AGRAS T40/T20 P

Unmanned Aircraft Flight Manual

3. Pull down the throttle stick or follow the onscreen instructions in the app to land the aircraft.

When using fixed RTK positioning, the aircraft will land directly instead of entering Landing

Protection. Landing Protection is still available if the aircraft is performing a fruit tree route

operation planned using DJI Terra.

Loss of Navigation Systems

When using xed RTK positioning, the aircraft will switch to GNSS if RTK is unavailable during ight.

If GNSS is also unavailable, the aircraft will switch to Attitude (ATTI) mode automatically to stabilize its

attitude and a prompt will appear in the app to remind users to y with caution and land as soon as

possible.

Control Station Failures

Control station failures include the following scenarios.

1. Control signal is lost: the aircraft will enter Failsafe RTH if Failsafe RTH is enabled in the app. Refer

to Loss of C2 Link for more information about Failsafe RTH. The aircraft action can also be set to

hovering in place until the aircraft lands with critically low battery level or landing directly.

2. The app crashes during automatic operations while the control signal is normal: in this case, the C2

link between the aircraft and the remote controller is in good condition, so the aircraft will continue

performing the current operation until landing is triggered by critically low battery level. Users can

exit from Route operations by moving the control stick slightly and control the aircraft manually.

Flyaway

The ight telemetry of the aircraft will be displayed on the screen of the remote controller during ight.

If the aircraft ies away during operation, users can search for the aircraft according to the location of

the aircraft and remote controller displayed on the map in the app. If the GNSS signal of the aircraft is

lost after the aircraft ies away then the aircraft will not be displayed on the map in the app. Users can

estimate the location of the aircraft to its last location, ight speed, and heading before the loss of the

GNSS signal.

Reporting Requirements

Users are responsible to inform DJI of any event of an uncontrolled crash or yaway within 2 business

days through DJI Support, a DJI authorized dealer, or other means and shall upload the flight data

related to the event. See the instructions of ight data upload from

https://youtu.be/X8sVce69z5g

Weight and Balance and Equipment List

Users can remove the spray tank and install the spreading system for spreading operations. The center

of gravity is within the ranges listed in the Center of Gravity Limitations section whether a spray tank or

spreading system is used.

Operation Resumption

When exiting a Route, A-B Route, or Fruit Tree operation, the aircraft will record a breakpoint. The

Operation Resumption function allows the user to pause an operation temporarily to rell the spray tank,

change the battery, or avoid obstacles manually. Afterwards, resume operation from the breakpoint.

Recording a Breakpoint

If GNSS signals are strong, a breakpoint will be recorded in the following scenarios during an operation.

If GNSS signals are weak, the aircraft will enter Attitude mode and exit the current operation. The last

position where GNSS signals were strong will be recorded as a breakpoint.

1. Tap the Pause or End button on the lower right corner of the screen. Note: tapping the End button

during an A-B Route operation does not cause the aircraft to record a breakpoint. The operation

ends immediately and cannot be resumed.

2. Initialize RTH.

3. Push the pitch or roll stick in any direction on the remote controller.

4. Obstacle detected. The aircraft brakes and enters obstacle avoidance mode.

5. Radar module error detected when its obstacle avoidance function is enabled.

6. The aircraft reaches its distance or altitude limit, or the aircraft is close to a GEO zone.

7. Empty tank.

8. The aircraft enters low-battery landing mode.

9. If the option “Continue operation if remote control signal is lost” is disabled in Aircraft Settings,

and the aircraft disconnects from the remote controller, the aircraft will record a breakpoint after it

performs the action preset for when signals are lost.

Make sure that the GNSS signal is strong when using the Operation Resumption function.

Otherwise, the aircraft cannot record and return to the breakpoint.

The breakpoint is updated as long as it meets one of the above conditions.

If RTK positioning is not in use and the operation is paused for longer than 25 minutes during

an A-B Route operation, the system will automatically switch to Manual operation mode and

erase the breakpoint.

Resuming Operation

1. Exit an operation through one of the above methods. The aircraft will record the current location as

the breakpoint.

2. Fly the aircraft to a safe location after operating the aircraft or removing the conditions for recording a

breakpoint.

3. Return Route

For Route operations, Flight-Efcient Operation Resumption becomes available if any of the following

conditions are met. The app will calculate the optimal return point according to the breakpoint and

the aircraft location to reduce the ying distance when carrying more payload. Make sure that Flight-

Efcient Operation Resumption is enabled in Advanced Settings under Aircraft Settings before using

the function.

The aircraft will land on the ground after the operation is paused.

Exit an operation by tapping the end button and then start this operation again in the Executing tag

in the operation list.

AGRAS T40/T20 P

Unmanned Aircraft Flight Manual

For Route operations that do not meet the conditions mentioned above, as well as operations in other

modes, the return route is as follows.

The default return route is to y back to the breakpoint. Users can also select a return point from

the list of return points and breakpoint on the screen, which means the aircraft will return to the task

route following a perpendicular line. After exiting an operation by tapping the end button, resume the

operation by selecting the Executing tag in the operation list to apply the operation again and select

the return route.

4. Tap Resume in the lower right corner of the screen and the aircraft will fly to the task route by

following the selected return route and continue spraying. For Route and Fruit Tree operations,

Connection Routing is supported for return ights.

the point marked D to the selected return point following a perpendicular line.

AGRAS T40/T20 P

Unmanned Aircraft Flight Manual

The amount of selectable return points is related to the position of the aircraft. Select

according to the app display.

Make sure that the aircraft has completely avoided the obstacle before resuming operation.

In the event of an emergency, make sure that the aircraft is operating normally and y the

aircraft manually to a safe area to resume operation.

Repeat the instructions above to exit and resume operation in the event of an emergency when

returning to the route, such as whenever obstacle avoidance is required.

System Data Protection

In Route, A-B Route, or Fruit Tree operation mode, the System Data Protection feature enables the

aircraft to retain vital system data such as operation progress and breakpoints after the aircraft is

powered off to replace a battery or rell the spray tank. Follow the instructions in Operation Resumption

to resume the operation after restarting the aircraft.

During Route operations, in situations such as when the app crashes or the remote controller

disconnects from the aircraft, the breakpoint will be recorded by the flight controller and recovered

automatically in the app once the aircraft is reconnected. If recovery is not performed automatically,

users can perform the operation manually. Go to Advanced Settings under Aircraft Settings in the app

and tap Continue Unnished Task. Recall the operation in the Executing tag in the operation list.

Empty Tank Warning

Prole

The aircraft calculates the empty tank and rell points according to the preset remaining liquid level

threshold, current remaining liquid level, aircraft status, and operation parameters and displays the

empty tank point on the map. In Route, A-B Route, and Fruit Tree operations, users can set the action

the aircraft will perform for empty tank point.

The empty tank point will not be displayed on the map if the tank is not calculated to run out

before the end of the task route.

For Route operations, when adding liquid to the spray tank or adjusting the operation

parameters, the empty tank point will update dynamically on the operating route according to

the amount of added liquid and the adjusted settings.

Usage

1. In Aircraft settings, enable the display of empty tank point and set the empty tank action.

2. When an empty tank warning appears in the app, the sprinklers automatically turn off and the aircraft

performs the preset empty tank action.

3. Land the aircraft and stop the motors. Rell the spray tank and tightly secure the cover.

4. Select an operation mode and continue the operation.

Payload - Spraying System

Equipped with the 2-channel electromagnetic ow meter and continuous liquid level gauge, the spraying

system provides users with accurate control of the magnetic drive impeller pumps and dual atomized

sprinklers.

Optional Payload - T40/T20P Spreading System

Introduction

The T40/T20P Spreading System is compatible with the Agras T40/T20P aircraft with a large spread tank

of 70 L and 35 L, respectively, and offers efcient and reliable spreading.

The spreading system has a built-in stirring device to prevent material blockages and improve operating

accuracy and reliability. The control module on the spreading system and the weight sensors on

the aircraft monitor the weight of the remaining material in the spread tank in real-time to improve

the accuracy of the spread rate control and empty tank warnings. The included fenders can block

spreading material that ies upward and prevent it from damaging the propellers. The quick-release

hopper gate allows for easy maintenance.

Users can congure spreading settings in the DJI Agras app and create specic templates for different

materials in order to meet different requirements. The app also provides warning prompts for an empty

tank as well as for abnormalities in rotational speed, temperature, and hopper outlet size.

Installation

Make sure to remove the Intelligent Flight Battery from the aircraft before installation.

Operate with caution to avoid injury caused by sharp or moving mechanical parts.

Check the parts on the aircraft and spreading system after installation to make sure that the

spinner disk will not damage the cables or any other part during operations.

The T40 Spreading System and T20P Spreading System are similar in appearance, but the spread tanks

are different sizes. Unless otherwise specied, the illustrations in this document use the T40 Spreading

System as an example.

1. On the aircraft, locate the hoses on either side of the spray tank. Loosen the nut on the hose

, take

the hose out of the hose clamp , rotate the clamp , and connect the hose to the protrusion on the

clamp . (Figure A)

Note: After the hose is removed, make sure to tighten the hose nut on the spray tank hose connector

to avoid losing the nut.

2. Locate the spraying system cable in front of the right landing gear on the aircraft. Unplug the cable

from the connector. Operate with caution to avoid damaging the cable. (Figure B)

3. Lift and remove the spray tank on the aircraft. (Figure C)

4. Insert the spreading system into the aircraft. (Figure D)

5. Connect the spreading system cable to the connector in step 2 and ensure a firm and accurate

connection. (Figure E)
