Foreword

THANK YOU for purchasing a John Deere product.

READ THIS MANUAL carefully to learn how to operate

and service your machine correctly. Failure to do so

could result in personal injury or equipment damage.

This manual and safety signs on your machine may also

be available in other languages. (See your John Deere

dealer to order.)

THIS MANUAL SHOULD BE CONSIDERED a

permanent part of your machine and should remain with

the machine when you sell it.

MEASUREMENTS in this manual are given in both

metric and customary U.S. unit equivalents. Use only

correct replacement parts and fasteners. Metric and

inch fasteners may require a specic metric or inch

wrench.

RIGHT-HAND AND LEFT-HAND sides are determined

by facing in the direction the machine or implement will

travel when going forward.

WRITE PRODUCT IDENTIFICATION NUMBERS (P.I.

N.) in the Specication or Identication Numbers

section. Accurately record all the numbers to help in

tracing the machine should it be stolen. Your dealer also

needs these numbers when you order parts. File the

identication numbers in a secure place o󰀨 the machine.

WARRANTY is provided as part of John Deere's

support program for customers who operate and

maintain their equipment as described in this manual.

The warranty is explained on the warranty certicate or

statement which you should have received from your

dealer.

This warranty provides you the assurance that John

Deere will back its products where defects appear within

the warranty period. In some circumstances, John

Deere also provides eld improvements, often without

charge to the customer, even if the product is out of

warranty. Should the equipment be abused, or modied

to change its performance beyond the original factory

specications, the warranty will become void and eld

improvements may be denied. Setting fuel delivery

above specications or otherwise overpowering

machines will result in such action.

If you are not the original owner of this machine, it is in

your interest to contact your local John Deere dealer to

inform them of this unit's serial number. This will help

John Deere notify you of any issues or product

improvements.

replace damaged, badly worn, or missing parts.

● Visually inspect that mower blades, blade bolts, and

the mower assembly are not worn or damaged. To

prevent machine damage, replace worn or damaged

blades and bolts in sets.

● If the machine is emitting heat or unusual smells, do

not operate it. Move the machine 50 ft (15 m) away

from buildings and combustible material, and contact

your service provider.

Check the Mowing Area

● Keep bystanders and pets out of the mowing area.

● Clear the area of objects such as rocks, wire, or toys,

which can be thrown by the blades. Remove low-

hanging branches or other obstacles, which can

interfere with your travel path.

● Study the mowing area. Set up a safe mowing path.

Do not mow where traction or stability is doubtful.

to loss-of-control and tipover accidents. Operation on

slopes and near terrain hazards requires extra

caution. Follow instructions in the Operating on

Slopes and Near Terrain Hazards section.

Weights and Attachments

● Some attachments require ballast weights. Follow

recommendations for wheel weights or

counterweights.

● Never give children a ride on a mower or in a cart

behind the mower, even when the blades are o󰀨.

They can fall o󰀨 and be run over or cut by the mower

blades. Children can interfere with mower operation.

Children who have been given rides in the past can

suddenly appear in the mowing area for another ride.

If you are not aware, they can be run over or backed

over by the mower.

● Children are often attracted to lawn mowers and

mowing activities, especially if they have been given

rides before. They do not know if the blades are

rotating or understand that they can be killed or

seriously injured even if the blades are not rotating.

● Keep children indoors and out of the mowing area

when the mower is being operated. Keep children

under the watchful eye of a responsible adult, other

than the operator. If there is not a responsible adult to

ensure that children stay indoors, DO NOT mow.

● Be alert to the presence of children or others. Turn o󰀨

the mower blades and stop the machine if someone

enters the mowing area.

● Look in the direction the machine is traveling. Before

and while backing, turn o󰀨 the mower blades and

look down and behind the machine carefully,

especially for children.

● Use extreme care when approaching objects that

block your view, such as blind corners, shrubs, or

trees, especially while backing. They can hide a

child.

Avoid Thrown Objects

● Clear the mowing area of all bystanders when using

this machine. Thrown objects could cause serious

injury or death.

● Clear the area of objects such as rocks, wire, or toys,

which can be thrown by the blades.

● Never direct discharged material toward anyone.

● Avoid discharging material against a wall or

obstruction such as a fence or retaining wall. Material

can ricochet towards the operator.

● Avoid discharging material towards a street or

roadway.

● Stop the blades when crossing gravel surfaces.

Operating on Slopes and Near Terrain

Hazards

● Slopes are a major factor related to loss of control

and tip-over accidents, which can result in serious

injury or death. Use caution and common sense

when operating on slopes.

● If you feel uneasy on a slope, do not mow or operate

the machine on it.

● Drive up and down slopes, not across them.

● Watch for holes, ruts, bumps, rocks, or other hidden

objects. Tall grass can hide obstacles.

● Drive slowly so you do not have to stop while on a

slope.

● Do not mow on wet grass. Tires can slip on wet grass

even if the brakes are working normally.

● Keep all movement on slopes slow and gradual. Do

not make sudden changes in speed or direction,

which can cause the ride-on mower to roll over.

● If the tires lose traction, disengage the PTO and

proceed slowly and carefully o󰀨 the slope.

● Do not shift to neutral and coast downhill.

Identify Safe Slopes

● Before using your machine, measure the slopes of all

mowing areas to determine which slopes are safe for

mowing with a ride-on mower. Use good judgment

and common sense when performing this survey.

Measuring Slopes

● Suggested method 1: Lay a straight piece of sturdy

lumber 1.2 m (4 ft) long on the slope and measure

the angle with an angle gauge or protractor level.

● Suggested method 2: Refer to the slope gauge

provided at the end of the manual.

Slope Limits

● Exceeding the recommended maximum slope angle

increases the risk of rollover accidents that can result

in serious injury or death.

GX100108—UN—14FEB20

● Never mow or operate this ride-on mower on slope

angles greater than 13°. (A 13° slope is a slope that

rises 1.4 m [4.6 ft] over a horizontal distance of 6.1 m

[20 ft].)

● Material collection systems, weather enclosures, or

other attachments increase the risk of a rollover.

Safety

10-2

● As slope increases the risk of rollover increases.

Operating Near Terrain Hazards

GX100106—UN—01FEB20

● Terrain hazards such as ditches and drop-o󰀨s are a

factor related to loss of control and tip-over

accidents, which can result in serious injury or death.

Use caution and common sense when operating

near terrain hazards.

● Do not mow or operate the machine in areas

adjacent to hazards that can cause the machine to

roll over. If a wheel goes over an edge or if the edge

breaks away, the machine can suddenly lose

traction, slide, and/or roll over.

● Hazards (A) include but are not limited to ditches,

drop-o󰀨s, embankments, or areas near bodies of

water.

● Maintain a bu󰀨er area (B) at least as wide as the

machine between hazards (A) and the mowing area

(C). Do not mow or operate the machine in the

hazard area or bu󰀨er area.

● Only mow or operate in the mowing area (C). Do not

exceed the recommended slope operating angle.

Refer to the Slope Limits section.

General Cleaning Guidelines

Machine must be inspected periodically throughout the

day. Buildup of debris must be removed to ensure

proper machine function and to reduce the risk of re.

Frequency of these inspections and cleanings vary

depending on a number of factors including operating

conditions, machine conguration, operating speeds,

and weather conditions. Inspections and cleanings may

be required multiple times throughout the day

particularly in dry, hot, and windy conditions.

Compressed air is not recommended for cleaning the

battery pack. Instead, using a handheld blower or

vacuum is the preferred method. If cleaning with

compressed air is the only method to apply, always wear

safety goggles or safety glasses with side shields when

using compressed air to clean the tool. If the operation

is dusty, also wear a dust mask.

IMPORTANT: Avoid re! Regular and thorough

cleaning of machine combined with other

routine maintenance procedures listed in the

Operator’s Manual greatly reduce the risk of

re, downtime, and improve machine

performance.

Besides proper maintenance the condition of

the material being handled is the most

signicant factor contributing to res. Dry,

light, and u󰀨y materials that can create a dust

cloud are the most likely to catch re. Debris

can accumulate in various areas especially on

horizontal surfaces. Conditions such as wind

speed and direction can change where the

material accumulates. Be aware of these

changing conditions and adjust your cleaning

schedule and practices to ensure proper

machine function and to reduce the risk of re.

Always follow all safety procedures posted on the

machine and in the Operator’s Manual. Before carrying

out any inspection or cleaning, always park machine

safely. (See Parking Safely in the Safety Section).

The entire machine should be inspected, with extra

attention given to the areas noted below.

Decommissioning — Proper Recycling and

Disposal of Fluids and Components

TS1133—UN—15APR13

Safety and environmental stewardship measures must

be taken into account when decommissioning a

machine and/or component. These measures include

the following:

● Use appropriate tools and personal protective

equipment such as clothing, gloves, face shields or

glasses, during the removal or handling of objects

and materials.

● Follow instructions for specialized components.

● Release stored energy by lowering suspended

machine elements, relaxing springs, disconnecting

the battery or other electrical power, and releasing

pressure in hydraulic components, accumulators,

and other similar systems.

● Minimize exposure to components which may have

residue from agricultural chemicals, such as

fertilizers and pesticides. Handle and dispose of

these components appropriately.

● Carefully drain engines, fuel tanks, radiators,

hydraulic cylinders, reservoirs, and lines before

recycling components. Use leak-proof containers

when draining uids. Do not use food or beverage

containers.

● Do not pour waste uids onto the ground, down a

drain, or into any water source.

● Observe all national, state, and local laws,

regulations, or ordinances governing the handling or

disposal of waste uids (example: oil, fuel, coolant,

brake uid); lters; batteries; and, other substances

or parts. Burning of ammable uids or components

in other than specially designed incinerators may be

prohibited by law and could result in exposure to

harmful fumes or ashes.

● Service and dispose of air conditioning systems

appropriately. Government regulations may require a

certied service center to recover and recycle air

conditioning refrigerants which could damage the

atmosphere if allowed to escape.

● Evaluate recycling options for tires, metal, plastic,

glass, rubber, and electronic components which may

be recyclable, in part or completely.

● Contact your local environmental or recycling center,

or your John Deere dealer for information on the

proper way to recycle or dispose of waste.

serviced incorrectly:

● Do not attempt to mount a tire without the

proper equipment and experience to perform

the job.

● Make sure that all tires are inated to the

recommended pressure, especially when

operating on slopes. Low pressure can

cause machine to become unstable on

slopes.

● Do not weld or heat a wheel and tire

assembly. Heat can cause an increase in air

pressure resulting in an explosion. Welding

can structurally weaken or deform the wheel.

● Do not stand in front or over the tire

assembly when inating. Use a clip-on chuck

and extension hose long enough to allow

you to stand to one side.

Using Troubleshoot Chart

If you are experiencing a problem that is not listed in this chart, see your Technical Manual or your service provider.

NOTE: The mower is designed with software that

monitors power demands from the mower blades

and wheel motors. In certain mowing conditions,

the power needed from operator inputs and mowing

conditions may surpass machine limits. When this

happens, the machine will lower travel speed to

allow the mower to keep operating with blades

engaged. To minimize the chances of this

happening, adjust mowing behavior by increasing

the height of cut to reduce the amount of grass

being cut, slowing down travel speed, or changing

the operating mode to Hi or Lo instead of bagging

mode.

John Deere Quality

John Deere equipment is more than just a purchase, it’s

an investment in quality. That quality goes beyond our

equipment to your John Deere dealer’s parts and

service support. This support is needed to keep you a

satised customer.

That’s why John Deere has initiated a process to handle

your questions or problems, should they arise. The

following three steps will help guide you through the

process.

Step 1

Refer to your operator’s manual

A. It has many illustrations and detailed information on

the safe and proper operation of your equipment.

B. It gives troubleshooting procedures, and specication

information.

C. It gives ordering information for parts catalogs,

service and technical manuals.

D. If your questions are not answered in the operator’s

manual, then go to Step 2.

Step 2

Contact your dealer

A. Your John Deere dealer has the responsibility,

authority, and ability to answer questions, resolve

problems, and fulll your parts and service needs.

B. First, discuss your questions or problems with your

dealer’s trained parts and service sta󰀨.

C. If the parts and service people are unable to resolve

your problem, see the dealership manager or owner.

D. If your questions or problems are not resolved by the

dealer, then go to Step 3.

Step 3

Contact John Deere

A. Your John Deere dealer is the most e󰀩cient source in

addressing any concern, but if you are not able to

resolve your problem after checking your operator’s

manual and contacting your dealer, contact John Deere

for assistance.

B. For prompt, e󰀨ective service, please have the

following ready before you call:

● The name of the dealer with whom you’ve been

working.

● Your equipment model number.

● Number of hours on machine (if applicable).

● Your serial number which you recorded on the inside

front cover of this manual.

● If the problem is with an attachment, your attachment

identication number.

C. Then call 1-800-537-8233 (United States and

Canada) and our advisor will work with your dealer to

investigate your concern. If you are outside the United

States and Canada, visit the following website:
