Preventing Injuries
Protect Children

JOHN DEERE S100 Series Lawn Tractors I - Safety 5

MXAL41929—UN—18FEB13

  • 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.
    OUO2005,0000783-19-15FEB20

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 up and down slopes, not across.
  • 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 configuration. The basic configuration 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].)
    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

GX100106—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 njury 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.
    OUO2005,0000785-19-09MAR20

Prevent Fires

JOHN DEERE S100 Series Lawn Tractors I - Safety 9

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 fire.
  • 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 flammable materials, such as straw, mulch, cloth, or chemicals. Do not park near an open flame 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 seat.
    OUO2005,0000788-19-15FEB20

Additional Safety Information
Towing Loads Safely

  • Stopping distance increases with speed and weight of towed load.
    Travel slowly and allow extra time and distance to stop.

  • Total towed weight must not exceed Towing Capacity stated in Specifications 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 first and positive last. Install positive terminal first 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 fluid, and batteries can harm the environment and people.
  • Do not use beverage containers for waste fluids – someone can mistakenly drink from them.
  • A Safety Data Sheet (SDS) provides specific 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.
    OUO2005,0000789-19-15FEB20

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 fire. Frequency of these inspections and cleanings vary depending on a number of factors including operating conditions, machine configuration, 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 damage! Regular and thorough cleaning of machine combined with other routine maintenance procedures listed in the Operator’s Manual greatly reduce the risk of fire, downtime, and improve machine performance.
Besides proper maintenance, the condition of the material being handled is the most significant factor contributing to fires. Dry, light, and fluffy materials that can create a dust cloud are the most likely to catch fire. Debris can accumulate in various areas especially on horizontal surfaces.

Checking and Adjusting Mower Deck Level
CAUTION: Avoid injury! Rotating blades are dangerous.
Before adjusting or servicing mower:

  • Disconnect spark plug wires or battery negative (-) cable to prevent engine from starting accidentally.
  • Always wear gloves when handling mower blades or working near blades.
    NOTE: Mower deck wheels should not contact the ground when leveling the mower deck.

Method One

  1. Make sure machine is on a flat, level surface.

  2. Park machine safely. (See Parking Safely in the Safety section.)

  3. Check that tires are inflated to correct tire pressure. Tire pressure is marked on the side of the tire.

  4. Raise deck to highest position.
    JOHN DEERE S100 Series Lawn Tractors I - Operating 4

  5. Place three short 51 mm (2 in) blocks of wood under the edges (A) of the mower deck.

  6. Lower mower deck to the 63 mm (2.5 in) cutting height position. For S130 models, lower deck to 57 mm (2-1/4 in) cutting height position.

  7. Check that the mower deck is level and lightly touching each of the three wooden blocks.
    JOHN DEERE S100 Series Lawn Tractors I - Operating 5● If the rear of the mower deck is not touching the rear blocks, or is sitting heavily on the blocks, adjust the rear lift links by turning the leveling nut (B) on each lift link. The blocks should be able to easily slide in and out beneath the mower deck when the mower deck is correctly adjusted.
    JOHN DEERE S100 Series Lawn Tractors I - Operating 6● If the front of the mower deck is not lightly touching the front block, adjust the front draft arm by turning the nut (C).

  • 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 flow chute before transport.

Using Weights
CAUTION: Avoid injury! The machine may become unstable when operating on slopes and/or with some attachments.
Use weights to improve stability when operating on slopes or using attachments.
Remove weights when not required.
IMPORTANT: Avoid damage! Never use liquid in tires or wheel weights as ballast. Transmission damage can occur.
When rear ballast is needed, use only the approved rear weight bracket and attaching weights.
NOTE: See your authorized dealer for recommended weights.

  • Install front weights for added stability and steering control when you use equipment, such as the rear-mounted grass bagger.
  • Install rear weights when using the snow blade or snowblower.
  • Remove weights when not required.
    MX00654,000039C-19-05JUL17

Using Tire Chains
IMPORTANT: Avoid damage! Do not use chains with mower deck.
Tire chains are recommended for use with most front attachments.
Remove tire chains before installing mower deck.
See your attachment operator’s manual for tire chain recommendation. See your authorized dealer for the chains.

Choosing Mower Blades
Three types of mower blades are available to use with 100 series models.

  • 3-N-1 blades. These are general purpose blades that are best suited for side-discharge operation, but can be used with a bagger attachment, or with a mulch cover installed. They are not designed for optimal performance when bagging or mulching.
  • Bagger blades. These blades are designed for optimal performance when used with bagger attachments.
  • Mulching blades. These blades are designed for optimal performance when used with a mulch cover installed.
    MG39705,00004AC-19-02JUL20

Mowing Tips
The following recommendations will produce the best lawn cut quality and appearance:

  • Keep mower blades sharp. Dull blades will tear grass; tips of grass will then turn brown.
  • Cutting grass too short may kill grass and let weeds grow easily.
    The suggested finished cut height should be within specified height range.

Specification
Finished Cut Height Range—Height. . . . . . . . . . . . . . . . . . . . 1.75 – 2.75 in. (44 – 70 mm)

  • Adjust cutting height to remove only 1/3 of the grass at a time.

  • Do not mow wet grass.

  • Mow grass often. Short grass clippings will decay quickly.
    CargO Mount is a trademark of Deere & Company

  • Mow with engine at full throttle.

  • Adjust travel speed to match mowing conditions:
    – Travel at slow speed when you mow thick, tall grass, make sharp turns or trim around objects.
    – Travel at moderate speed when you mow thin grass.

  • Use a different mowing pattern each time you mow. Overlap mowing paths by specified distance.
    Specification
    Overlap Mowing Paths—Distance. . . . . . . . . . . . . . . . . . . . . . . . . 50 – 100 mm (2 – 4 in.)

  • Drive over ridges and through shallow ditches straight-on, not at an angle.
    JOHN DEERE S100 Series Lawn Tractors I - Operating 30

  • Mow around the outside twice, then mow inside in straight passes.
    Best cut is achieved when mowing in a straight line.
    When mowing or mulching near pavement, overlap the pavement by 50 mm (2 in.) to allow clippings to dispense over grass.

  • A thick layer of mulched leaves can prevent sunlight from getting to grass and smother it. Taller grass heights allow mulched leaves to dispense easier in lawn. Mulch leaves several times if needed.

  • Use a thatcher in late spring or summer to pull up dead grass and aerate ground.

  • For Mulching Mower: Shorter cut heights will provide better cut quality, but may leave noticeable clippings. Higher cut heights will reduce clippings, but cut quality may decline.
    OUO1023,00001B8-19-01MAR13

Towing Loads
IMPORTANT: Avoid damage! Towing excessive trailer loads at full speeds for long distances and up slopes can stress drivetrain components. To avoid damage to drivetrain components, use the following guidelines.

  • Total towed weight must not exceed combined weight of pulling machine, ballast, and operator. Use counterweights or wheel weights as described in an attachment or pulling machine operator’s manual.
  • When towing over 150 kg (350 lbs.), depress forward travel pedal no more than halfway to avoid transmission damage. Always run tractor at full throttle when towing loads.
  • Avoid inclines greater than a 10 degrees slope while towing to avoid damage to the pulling machine. Use the Slope Guide located in this operator’s manual to ensure proper machine towing operation. See SAFETY, Operating on Slopes in this operator’s manual for additional information.
    IMPORTANT: Avoid damage! Always run tractor at full throttle when PTO is engaged and when towing loads.

Using Proper Fuel and Stabilizer
IMPORTANT: Avoid damage! Using stale, contaminated, or improper fuel can result in engine and fuel system damage.
Repairs caused by stale, contaminated, or improper fuel are not covered by warranty.
Use regular grade unleaded fuel with an octane rating of 87 octane or higher. Fuel blends containing up to 10% ethanol or up to 15% MTBE reformulated fuel are acceptable. Do not use fuel or additives containing methanol as engine damage can occur.
Always use fresh, clean fuel that is purchased in a quantity that can be used within approximately 30 days. Fuel stabilizer should always be added to the fuel each time fuel is purchased. Add stabilizer before filling the fuel container to insure proper mixing. Such practice helps prevent engine performance problems and allows fuel storage in the machine all year without draining.
Store fuel in plastic containers to reduce condensation. Make sure that the cap on the fuel container is tight to reduce fuel contamination and evaporation. For best fuel storage life, use a self-sealing gas can.
Fuel is blended to give best seasonal performance. To avoid engine performance problems such as hard starting or vapor lock, use inseason fuel. Use fuel during warm weather that was purchased during that season, and use fuel during cold weather that was purchased during that season.
Fuel can become stale in machines with engines that are used seasonally or infrequently during a season. Stale fuel can produce varnish and plug carburetor or EFI components which can affect engine performance.
Keep fuel storage container tightly covered and in a cool area out of direct sunlight. Fuel can break down and degrade if not sealed properly or exposed to sun and heat.
Condensation may collect in the fuel tank because of a variety of operating or environmental conditions and, over time, may affect your machine’s operation. Fill machine fuel tank at the end of the day.
MP47322,00F4674-19-26MAY15

Filling Fuel Tank
CAUTION: Avoid injury! Fuel vapors are explosive and flammable:

  • Shut engine off before filling fuel tank.

  • Allow engine to cool before refueling.

  • Do not smoke while handling fuel.

  • Keep fuel away from flames or sparks.

  • Fill fuel tank outdoors or in ventilated area.

  • Clean up spilled fuel immediately.

  • To prevent static electric discharge, use a clean, approved non-metal container.
    IMPORTANT: Avoid damage! Dirt and water in fuel causes engine damage:

  • Clean dirt and debris from the fuel tank opening.

  • Use clean, fresh, stabilized fuel.

  • To keep condensation out of the fuel tank, fill the fuel tank at the end of operation each day.

  • If using a funnel, make sure it is plastic and has no screen or filter.

To prevent condensation and freezing during cold weather, fill fuel tank at the end of operation each day.

  1. Park machine safely. (See Parking Safely in the Safety section.)
  2. Allow engine to cool.
  3. Remove any trash from area around fuel tank cap.
  4. Remove fuel tank cap slowly to allow any pressure built up in tank to escape.
  5. Fill fuel tank only to bottom of filler neck. Do not overfill.
  6. Install fuel tank cap and turn cap until it clicks.

Checking Tire Pressure
CAUTION: Avoid injury! Explosive separation of tire and rim parts is possible when they are 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 inflated 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 inflating. Use a clip-on chuck and extension hose long enough to allow you to stand to one side.
  1. Check tires for damage.
  2. Check tire pressure with an accurate low-pressure gauge.
  3. A lower pressure will improve traction and performance depending on turf conditions or if transport areas have steep inclines.
  4. Add or remove air to meet specified tire pressure. (See Specifications section for recommended tire pressures.)

Storage

Storing Safety
CAUTION: Avoid injury! Fuel vapors are explosive and flammable.
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 fires and structure fires can occur. Fires can occur if debris is not removed from around the engine and muffler, or if stored near combustible materials.
  • Do not store vehicle with fuel in the tank inside a building where fumes reach an open flame 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 five minutes.

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

  8. Lubricate grease points and check tire pressure.
    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 filling 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 filter.

  2. Service air filter 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 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.

  10. Store the vehicle in a dry, protected place. If vehicle is stored outside, put a waterproof cover over it.
    RM87422,00007C9-19-19JUL17

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 specified torque.
  6. Lubricate all grease points.
  7. Open fuel shut-off 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 deflectors are in place.

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 2021 or 2022 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, filters, 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, Z335E, Z345M, Z345R, Z355E, Z355R, Z365R, Z375R, Z515E, Z545R, 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 abuse, neglect, or improper maintenance or unapproved modifications.
  • 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 first scheduled replacement point for that part. If the part fails prior to the first 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 first 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 emissionsrelated warranted part.
  • Add-on or modified parts that are not exempted by the California Air Resources Board may not be used. The use of any non-exempted add-on or modified 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 modified part.

IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, TO THE EXTENT APPLICABLE, SHALL BE LIMITED IN DURATION TO THE APPLICABLE ADJUSTMENT PERIOD SET FORTH HERE. THE PURCHASER’S ONLY REMEDIES IN CONNECTION WITH THE BREACH OR PERFORMANCE OF ANY WARRANTY ON JOHN DEERE BATTERIES ARE THOSE SET FORTH HERE. IN NO EVENT WILL THE DEALER, JOHN DEERE OR ANY COMPANY AFFILIATED WITH JOHN DEERE BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES. (Note: Some states 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 specific legal rights, and you may also have some rights which vary from state to state.

NO DEALER WARRANTY
The selling dealer makes no warranty of its own and the dealer has no 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.
