Using Your Operator’s Manual

Read this operator’s manual, watch the safety video,

www.deere.com/QR and review the safety signs on your

machine before use. They all contain important safety

information and operating instructions that must be

followed to help keep you and others safe. Be sure

everyone who uses the machine has read the manual,

reviewed the safety signs, and knows how to use the

machine safely and properly.

Your machine was designed and built to be operated in

accordance with all the safe operating instructions.

Since it was designed to cut grass, it can amputate

hands and feet and throw objects. If you do not follow

safety instructions, serious injury or death can occur.

This operator manual is organized in sections to help

you nd information quickly. You can use this manual to

nd answers to many of your operating and servicing

questions. An index at the end of this book helps you

nd needed information quickly. Contact your dealer if

this manual does not answer your questions.

Before using your machine:

● Know how to operate the machine. The Operating

Controls section helps you understand the controls of

your machine and what they do.

● Prepare your machine and the mowing area by

performing required daily checks outlined in the

General Instructions section.

● Follow instructions in the Preventing Injuries section,

especially related to:

- Keeping children safe by following instructions in

the Protect Children section.

- Avoiding injury on slopes and near terrain

hazards by following instructions in the Operating

on Slopes and Near Terrain Hazards section.

- Follow the instructions in the Avoid Thrown

Objects section and keep all guards in place,

including discharge chute.

- Cleaning machine during use and before storing

as outlined in the Prevent Fires section.

● Understand how to service and inspect your

machine.

If you do not understand the instructions or have

questions, contact your dealer.

item referenced is hidden from view.

Before delivering this machine, your dealer performed a

predelivery inspection to ensure best performance.

Preventing Injuries

Protect Children

MXT005340—UN—06JUN13

● Children can be killed or seriously injured by riding

mowers when operators do not follow safe operating

practices.

● Do not mow in reverse. Operating with the mower

engaged while backing up is discouraged.

● 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.

OUO2005,000078C-19-15FEB20

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.

● Mow across slopes, not up and down.

● 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.

Safety

10-2

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.

● As slope increases the risk of rollover increases.

Operating Near Terrain Hazards

GX100105—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.

SDHTXN6,1746613701194-19-07MAY25

of towed load. Travel slowly and allow extra time and

distance to stop.

● Total towed weight must not exceed Towing Capacity

stated in Specications of this manual.

● Excessive towed load can cause loss of traction and

loss of control on slopes. Reduce towed weight when

operating on slopes.

● Never allow children or others in or on towed

equipment.

● Use only approved hitches. Tow only with a machine

that has a hitch designed for towing. Do not attach

towed equipment except at the approved hitch point.

● Towed equipment increases the risk of rollover on

slopes. Refer to the Operating on Slopes and Near

Terrain Hazards section for more information.

● Do not turn sharply. Use additional caution when

turning or operating on adverse surface conditions.

Use care when reversing.

Safe Transportation

Follow instructions in the Transporting Machine on

Trailer section.

● Use a full-width loading ramp at least 30 cm (12 in)

wider than the machine, never two separate ramps.

Service and Maintenance

● Proper service and maintenance of the machine is

essential.

● Keep all parts in good condition, keep all nuts and

bolts tight, and repair any damage immediately. Stop

and inspect the machine immediately if you strike an

object.

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.

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.

Storing Safety

CAUTION: Avoid injury! Fuel vapors are

explosive and ammable.

Engine exhaust fumes contain carbon

monoxide and cause serious illness or death:

● Run the engine only long enough to move

the machine to or from storage.

● If a machine is stored before allowing it to

cool, machine res and structure res can

occur. Fires can occur if debris is not

removed from around the engine and mu󰀪er,

or if stored near combustible materials.

● Do not store vehicle with fuel in the tank

inside a building where fumes reach an open

ame or spark.

● Allow the engine to cool before storing the

machine in any enclosure.

MP47322,00F4680-19-06MAY15

Preparing Machine for Storage

1. Repair any worn or damaged parts. Replace parts if

necessary. Tighten loose hardware.

2. To prevent rust, repair scratched or chipped metal

surfaces.

3. Remove grass and debris from machine.

4. Clean under the rotary deck and remove grass and

debris from inside chute and bagger, if applicable.

5. Wash the machine and apply wax to metal and

plastic surfaces.

6. To dry belts and pulleys, run machine for ve

minutes.

7. To prevent rust, apply light coat of engine oil on pivot

and wear points.

8. Lubricate grease points and check tire pressure.

Preparing Fuel and Engine For Storage

Fuel:

If you have been using “Stabilized Fuel,” add stabilized

fuel to tank until the tank is full.

NOTE: Filling the fuel tank reduces the amount of air in

the fuel tank and helps reduce deterioration of fuel.

If you are not using “Stabilized Fuel”:

1. Park machine safely in a well-ventilated area. (See

Parking Safely in the Safety section.)

NOTE: Try to anticipate the last time the machine will be

used for the season so very little fuel is left in the

fuel tank.

2. Turn on engine and allow to run until it runs out of

fuel.

3. For machines equipped with key switch, turn key to

o󰀨 position.

IMPORTANT: Avoid damage! Stale fuel can produce

varnish and plug carburetor or injector

components and a󰀨ect engine performance.

● Add fuel conditioner or stabilizer to fresh fuel

before lling tank.

4. Mix fresh fuel and fuel stabilizer in separate

container. Follow stabilizer instructions for mixing.

5. Fill fuel tank with stabilized fuel.

6. Run engine for a few minutes to allow fuel mixture to

circulate through carburetor on gas engine or fuel

injectors on diesel engine.

Engine:

Engine storage procedure should be used when vehicle

is not to be used for longer than 60 days.

1. Change engine oil and lter while engine is warm.

2. Service air lter if necessary.

3. Clean debris from engine air intake screen.

4. On gas engines:

● Remove spark plugs. Put 30 mL (1 oz) of clean

engine oil in cylinders.

● Install spark plugs, but do not connect spark plug

wires.

● Crank the engine 5 or 6 times to allow oil to be

distributed.

5. Clean the engine and engine compartment.

6. Remove battery.

7. Clean the battery and battery posts. Check the

electrolyte level if your battery is not maintenance

free.

8. Close fuel shuto󰀨 valve if your machine is equipped.

9. Store the battery in a cool, dry place where it will not

freeze.

NOTE: The stored battery should be recharged every 90

days.

10. Charge the battery.

IMPORTANT: Avoid damage! Prolonged exposure to

sunlight could damage surfaces. Store machine

inside or use a cover if stored outside.

11. Store the vehicle in a dry, protected place. If vehicle

is stored outside, put a waterproof cover over it.

OUMX068,000077B-19-05JUL17

Removing Machine From Storage

1. Check tire pressure.

2. Check engine oil level.

3. Check battery electrolyte level if your battery is not

maintenance free. Charge battery if necessary.

4. Install battery.

5. On gas engines: check spark plug gap. Install and

tighten plugs to specied torque.

6. Lubricate all grease points.

7. Open fuel shut-o󰀨 valve if your machine is equipped.

8. Run the engine 5 minutes without the mower or any

attachments running to allow oil to be distributed

throughout engine.

9. Be sure all shields and guards or deectors are in

place.

U.S. EPA Emission Control System

Warranty Statement (O󰀨-Road Engine

Equipment)

Your Warranty Rights and Obligations

John Deere and the United States Environmental

Protection Agency are pleased to explain the emission

control system's warranty on your o󰀨-road engine

equipment. John Deere must warrant the emission

control system on your o󰀨-road engine equipment for

the period listed below provided there has been no

abuse, neglect or improper maintenance of your o󰀨-

road engine equipment leading to the failure of the

emission control system.

Manufacturer’s Warranty Coverage

Your evaporative emission control system is warranted

for two years. Your o󰀨-road engine is warranted as

follows: If your o󰀨-road engine equipment has a Briggs

& Stratton engine, your o󰀨-road engine is warranted for

two years. For all other o󰀨-road engines referenced in

this Operator's Manual, your o󰀨-road engine is

warranted for three years. If any emission-related part

on your o󰀨-road equipment is defective, the part will be

repaired or replaced by John Deere or an authorized

John Deere service provider.

Owner’s Warranty Responsibilities

● As the spark ignited o󰀨-road engine equipment

owner, you are responsible for the performance of

the required maintenance listed in your Operator’s

Manual. John Deere recommends that you retain all

receipts covering maintenance on your spark ignited

o󰀨-road engine equipment, but John Deere cannot

deny warranty coverage solely for lack of receipts or

for your failure to ensure the performance of all

scheduled maintenance.

● As the spark ignited o󰀨-road engine equipment

owner, you should however be aware that John

Deere may deny you warranty coverage if your spark

ignited o󰀨-road engine equipment or a part has failed

due to abuse, neglect, or improper maintenance or

unapproved modications.

● You are responsible for presenting your spark ignited

o󰀨-road engine equipment to a John Deere Turf and

Compact Utility distribution center or service center

as soon as a problem exists. The warranty repairs

shall be completed in a reasonable amount of time,

not to exceed 30 days. If you have a question about

your emission control warranty coverage, your

emission control warranty rights and responsibilities,

how to make an emission control system warranty

claim or how to make arrangements for emission-

related authorized repairs, you should contact your

John Deere Turf and Compact Utility retailer, or the

John Deere Customer Contact Center at 1-800-537-

8233, or email John Deere from

https://www.deere.com/en/our-company/contact-us/.

General Emission Control System Warranty

Coverage

The warranty period begins on the date the spark

ignited o󰀨-road engine equipment is delivered to an

ultimate purchaser. John Deere warrants to the ultimate

purchaser and each subsequent purchaser that the

spark ignited o󰀨-road engine equipment is:

● Designed, built and equipped so it conforms at the

time of sale to the ultimate purchaser with applicable

U.S. Environmental Protection Agency regulations

under 40 CFR Parts 1054, 1048 and 1060; and,

● Free from defects in materials and workmanship that

causes the failure of a warranted part to conform with

Warranty

85-1

applicable regulations for the emission control

system warranty period provided herein.

● For owners located more than 100 miles from a John

Deere authorized service center, John Deere will pay

either for shipping costs to and from an authorized

service center, provide for a service technician to

come to the owner to make the warranty repair, or

pay for the repair to be made at a local non-

authorized service center. These provisions do not

apply to high-altitude counties within the following

States: Alaska, Hawaii, Arizona, Colorado, Idaho,

Montana, Nebraska, Nevada, New Mexico, Oregon,

Texas, Utah, and Wyoming.

Emission Control System Warranty Interpretation

● Any warranted part that is not scheduled for

replacement as required by the maintenance

instructions in the Operator's Manual is warranted as

provided herein. If any such part fails during the

period of warranty coverage it will be repaired or

replaced by John Deere or an authorized John Deere

service provider. Any such part repaired or replaced

under warranty is warranted for the remaining

warranty period.

● Any warranted part that is scheduled only for regular

inspection in the maintenance instructions in the

Operator’s Manual is warranted as provided herein.

A statement in the Operator’s Manual to the e󰀨ect of

“repair or replace as necessary” does not reduce the

period of warranty coverage. Any such part repaired

or replaced under warranty is warranted for the

remaining warranty period.

● Any warranted part that is scheduled for replacement

as required maintenance in the Operator's Manual is

warranted for the period of time prior to the rst

scheduled replacement point for that part. If the part

fails prior to the rst scheduled replacement, the part

will be repaired or replaced by John Deere or an

authorized John Deere service provider. Any such

part repaired or replaced under warranty is

warranted for the remainder of the period prior to the

rst scheduled replacement point for the part.

● Repair or replacement of any warranted part under

the warranty will be performed at no charge to the

owner by John Deere or an authorized John Deere

service provider.

● The owner will not be charged for diagnostic labor

which leads to the determination that a warranted

part is defective, provided such work is performed by

John Deere or an authorized John Deere service

provider.

● John Deere or an authorized John Deere service

provider will repair damages to other engine

components proximately caused by a failure under

warranty of any emission-related warranted part.

● Add-on or modied parts that are not exempted by

the California Air Resources Board may not be used.

The use of any non-exempted add-on or modied

parts will be grounds for disallowing a warranty claim.

John Deere or any authorized John Deere service

provider will not be liable to warrant failures of

warranted parts caused by the use of a non-

exempted add-on or modied part.

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:
