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 off. They can fall off 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 off 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 off 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 off the slope.
● Do not shift to neutral and coast downhill.
Identify Safe Slopes
● Before using your machine, measure 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° with ride-on mower in its basic conguration. The basic
conguration is the ride-on mower with a mower deck and no other
attachments. (A 13° slope is a slope that rises 1.4 m [4.6 ft] over a
horizontal distance of 6.1 m [20 ft].)
Safety
10
GX100111—UN—19FEB20
● Attachments such as material collection systems, weather
enclosures, or other attachments increase the risk of a rollover.
When using attachments, never mow or operate this ride-on mower
on slope angles greater than 10°. (A 10° slope is a slope that rises 1
m [3.5 ft] over a horizontal distance of 6.1 m [20 ft].)
● The risk of rollover is low on slopes of 10° or less. As the slope
angle increases to the recommended maximum, the risk increases
to a medium level.
Operating Near Terrain Hazards
GX100105—UN—01FEB20
● Terrain hazards such as ditches and drop offs 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-offs,
embankments, or areas near bodies of water.
● Maintain a buffer 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 buffer area.
● Only mow or operate in the mowing area (C). Do not exceed the
recommended slope operating angle. Refer to the Slope Limits
section.
OUO2005,000078A-19-09MAR20
Prevent Fires
TS227—UN—15APR13
● Do not mow tall, dry grass or through piles of leaves. Combustible
materials can contact hot components and increase the risk of re.
● Debris can build up anywhere on the machine, especially on
horizontal surfaces. While using your machine, periodically check
for and remove debris, especially in dry or heavy debris conditions,
such as when collecting leaves.
● After operating, completely remove any combustible materials from
equipment before storing. Use compressed air, a leaf blower, or
water to keep the machine clean.
● Allow machine to cool in an open area before storing. Do not park
machine near ammable materials, such as straw, mulch, cloth, or
chemicals. Do not park near an open ame or other sources of
ignition, such as a water heater or furnace.
● Excess lubrication or fuel/oil leaks or spills on the machine can also
provide collection sites for debris. Promptly cleaning up spills and
repairing leaks reduces the potential for debris collection.
● Refer to the Machine Cleanout section for more information on
checking for debris buildup and locations to inspect.
● Always park the machine safely before cleaning or servicing a
machine. See the Parking Safely section.
OUO2005,0000787-19-15FEB20
Parking Safely
Always apply the park brake and remove the key before leaving the
machine unattended. Children or others may attempt to move or
operate an unattended machine.
● Stop the machine on a level surface.
● Disengage mower blades or other attachments.
● Lower attachments to the ground.
● Apply the park brake.
● Stop the engine.
● Remove the key.
● Wait for engine and all moving parts to stop before you leave the

Travel slowly and allow extra time and distance to stop.
● Total towed weight must not exceed Towing Capacity stated in
Specications 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.
● Ensure that all safety devices, discharge chute, and grass catcher
components are in good condition and replace when necessary.
● Understand service procedures thoroughly before working on the
machine. If you do not understand the service procedures or are
uncomfortable working in your machine, contact your servicing
dealer.
● Disconnect the battery or all spark plug wires before servicing the
machine. Disconnect negative terminal rst and positive last. Install
positive terminal rst and negative last.
● Some components could have stored energy in springs or hydraulic
components. Servicing procedures described in the Service section
describe how to perform service and maintenance tasks safely.
● Support any machine elements that must be raised for service
work. Use jack stands or service locks to support components
when needed.
Disposing of Waste Products and Chemicals
● Waste products, such as used oil, fuel, coolant, brake uid, and
batteries can harm the environment and people.
● Do not use beverage containers for waste uids – someone can
mistakenly drink from them.
● A Safety Data Sheet (SDS) provides specic details on chemical
products: Physical and health hazards, safety procedures, and
emergency response techniques. The seller of the chemical
products used with your machine is responsible for providing the
SDS for that product.
● To learn how to recycle or properly dispose of waste products
generated from service, see your local recycling center or
authorized dealer. If you wish to discard the machine, contact your
local recycling center or authorized dealer.

Machine Cleanout
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 conguration, 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 signicant factor contributing to
res. Dry, light, and uffy 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.

Be sure that trailer has all the necessary lights and signs required by
law.
CAUTION: Avoid injury! Use extra care when loading or
unloading the machine onto a trailer or truck. Machine
wheels can go off the ramp or trailer, causing the machine to
tip over.
● To load, back slowly and in a straight line. Keep wheels
away from drop-offs and edges.
● Do not use two separate loading ramps. Use full width
loading ramp at least 30 cm (12 in) wider than machine to
keep caster wheels from going off the ramp edge.
● Use a trailer with sides.
1. Park trailer on level surface.
2. Fully raise mower deck before driving machine onto trailer.

Transporting Material Collection System (If
Equipped)
If the material collection system is left on the machine during transport,
follow these guidelines when trailering the unit:
● Empty the cloth bags and remove them from the hopper. Full bags
add extra weight which can overstress the hopper frame on rough
roads. At road travel speeds, wind can cause premature wear of the
cloth bags.
● Make sure that the hopper cover is latched securely to the hopper
frame.
● If the unit is transported over long distances or at high speeds,
remove the rear bagger or power ow chute before transport.

Emissions Service Information
A qualied repair shop or person of the owner’s choosing may
maintain, replace, or repair emission control devices and systems with
original or equivalent replacement parts. However, warranty, recall and
all other services paid for by John Deere must be performed at an
authorized John Deere service center.
Within the warranty period, John Deere will reimburse reasonable
service costs incurred at service providers outside the John Deere
authorized network only in an unsafe, emergency condition if an
authorized John Deere dealer is not available and the failure does not
arise from the owner’s misuse or failure to perform required
maintenance. An emergency situation exists under this section if, after
30 days, the authorized John Deere network is unable to perform the
repairs or source replacement parts.
Emission Control System Certication Label
NOTE: Tampering with emission controls and components by
unauthorized personnel may result in severe nes or penalties.
Emission controls and components can only be adjusted by EPA
and/or CARB authorized service centers. Contact your John
Deere Retailer concerning emission controls and component
questions.
The presence of an emissions label signies that the engine has been
certied with the United States Environmental Protection Agency
(EPA) and/or California Air Resources Board (CARB).
The emissions warranty applies only to those engines marketed by
John Deere that have been certied by the EPA and/or CARB; and
used in the United States and Canada in off-road mobile equipment.
Altitude Adjustment (Gasoline or Propane Converted Engines
Only)
If your engine features a carburetor it is calibrated by the engine
manufacturer and is not adjustable.
If your engine is operated at altitudes below 610 m (2,000 ft.), a high
altitude carburetor jet kit is not required. If your engine is operated at
altitudes above 610 m (2,000 ft.), a high altitude carburetor jet kit may
be required for proper engine performance and emissions control.
Operating the engine with the wrong carburetor conguration at a
given altitude may increase the engine’s emissions and decrease fuel
efciency and performance.
See a qualied service provider for details on jet kit requirements for
your specic product.

Gasoline Fuel for 4-Cycle Engines
Use unleaded gasoline with a minimum octane rating of 87 AKI (anti-
knock index) or 90 RON (research octane number). Gasoline fuels
specied to EN 228 or ASTM D4814 are recommended.
Fuel blends of unleaded gasoline with a maximum 10% ethanol or
15% MTBE (methyl tertiary-butyl ether) are also acceptable.
CAUTION: Reduce the risk of re. Handle fuel carefully. DO
NOT ll the fuel tank when the engine is running or hot. Stop
engine and allow it to cool for several minutes before lling
fuel tank. Fill fuel tank only to the bottom of the ller neck.
Refuel outdoors. DO NOT smoke while you ll the fuel tank
or service the fuel system.
Store fuel in properly identied polyethylene containers.
When storing fuel, add John Deere Gasoline Conditioner and
Stabilizer (or equivalent) at the specied concentration.
IMPORTANT: DO NOT use methanol or fuel blends that contain
methanol.
Avoid spilling fuel. Gasoline can damage plastic and
painted surfaces.
DO NOT mix oil with gasoline.

MP47322,00F4681-19-13JUL16
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 off position.
IMPORTANT: Avoid damage! Stale fuel can produce varnish and
plug carburetor or injector components and affect 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.
Storage
51
8. Close fuel shutoff 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
specied torque.
6. Lubricate all grease points.
7. Open fuel shut-off valve if your machine is equipped.

California and U.S. EPA Emissions Control System
Warranty Statement (Off-Road Gas Engines)
Your Warranty Rights and Obligations
The California Air Resources Board, John Deere, and the United
States Environmental Protection Agency are pleased to explain the
emissions control system’s warranty on your model year 2023 or 2024
spark ignited off-road engine equipment. In California, new equipment
that uses small or large (less than 1 liter) spark ignited off-road
engines must be designed, built and equipped to meet the state’s
stringent anti-smog standards. John Deere must warrant the
emissions control system on your spark ignited off-road engine
equipment for the period listed below provided there has been no
abuse, neglect or improper maintenance of your equipment leading to
the failure of the evaporative emissions system.
Your emissions control system may include parts such as: carburetors
or fuel-injection system, ignition system, catalytic converters, fuel
tanks, valves, lters, clamps, connectors, fuel lines (for liquid fuel and
fuel vapors) and other associated components. Also included may be
hoses, belts, sensors and other emission-related assemblies.
Where a warrantable condition exists, John Deere will repair your
spark ignited off-road engine equipment at no cost to you including
diagnosis, parts and labor.
Manufacturer’s Warranty Coverage
This emissions control system is warranted for two years for models
S100, S110, S120, S130, S140, S150, S160, S170, S180, S220,
X330, Z315E, Z325E, Z515E, Z545R, Z735E, Z735M, 1220, and three
years for all other models referenced in this operator’s manual. If any
emissions related part on your equipment is defective, the part will be
repaired or replaced by John Deere.
Owner’s Warranty Responsibilities
● As the spark ignited off-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 off-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 off-road engine equipment owner, you should
be aware that John Deere may deny you warranty coverage if your
spark ignited off-road engine equipment or a part has failed due to
Warranty
54
abuse, neglect, or improper maintenance or unapproved
modications.
● You are responsible for presenting your spark ignited off-road
engine equipment to a John Deere Turf and 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 emissions
warranty coverage, how to make an emissions warranty claim or
how to make arrangements for emissions-related authorized
repairs, you should contact your John Deere Turf and 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 Emissions Warranty Coverage
The warranty period begins on the date the equipment is delivered to
an ultimate purchaser. John Deere warrants to the ultimate purchaser
and each subsequent purchaser that the spark ignited off-road engine
equipment is:
● Designed, built and equipped so as to conform to all applicable
regulations adopted by the California Air Resources Board;
● Designed, built and equipped so as to conform at the time of sale to
the ultimate purchaser with applicable U.S. Environmental
Protection Agency regulations under 40 CFR Parts 1054 and 1060:
and,
● Free from defects in materials and workmanship which cause such
engine to fail to conform with applicable regulations for the
Emissions 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 Alaska, Hawaii, Arizona,
Colorado, Idaho, Montana, Nebraska, Nevada, New Mexico,
Oregon, Texas, Utah, and Wyoming.
Emissions 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. 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
effect 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. 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 at any authorized John
Deere Turf and Utility retailer.
● 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 will repair damages to other engine components
proximately caused by a failure under warranty of any emissions-
related warranted part.
● Add-on or modied parts that are not exempted by the California Air
Resources Board may not be used. The use of any non-exempted
add-on or modied parts will be grounds for disallowing a warranty
claim. John Deere will not be liable to warrant failures of warranted
parts caused by the use of a non-exempted add-on or modied
part.

do not allow limitations on how long an implied warranty lasts or the
exclusion or limitation of incidental or consequential damages. So
these limitations and exclusions may not apply to you.) This warranty
gives you specic legal rights, and you may also have some rights
which vary from state to state.

authority to make any representation or promise on behalf of John
Deere, or to modify the terms or limitations of this warranty in any way.
