SERVICE ELECTRICAL Checking the Battery c CAUTION: Sulfuric acid in battery electrolyte is poisonous. It is strong enough to burn skin, eat holes in clothing, and cause blindness if splashed into eyes. Wear eye protection and avoid spilling or dripping electrolyte. Flush eyes with water for 15-30 minutes if acid is splashed into eyes. If acid is swallowed, get medical attention immediately. DO NOT attempt to open, add fluid or service battery.
SERVICE ELECTRICAL Clean Battery and Terminals c CAUTION: Battery gas can explode, to avoid injury: - Keep sparks and flames away from batteries.

Disconnect BLACK (–) battery cable (B) first. 4.
SERVICE ELECTRICAL Charging the Battery c CAUTION: BE VERY CAREFUL: Battery fluid (electrolyte), is a solution of water and sulfuric acid. It is very harmful to eyes, skin, or clothing. - Wear goggles or an eye shield when you work with a battery. - If the acid contacts your eyes, skin, or clothing, flush the area immediately with water. Get medical help, if necessary. A battery gives off gas which can explode. An exploding battery will spray sulfuric acid in all directions.
SERVICE ELECTRICAL c CAUTION: DO NOT attempt to open, add fluid or service battery. Any attempt to do so will void warranty and lead to possible injury. Battery gas is explosive: - DO NOT smoke while you charge battery. - Keep all flames and sparks away. - DO NOT charge frozen battery. - DO NOT connect booster battery negative (-) cable to starting vehicle negative (-) terminal. 1. Remove battery from mower. (See Removing and Installing Battery in this section.) 2.

Insert bulb socket into housing, push in and turn 1/4 turn clockwise to install. 5. Lower hood.
SERVICE MISCELLANEOUS Checking Tire Pressure c CAUTION: Explosive separation of a tire and rim parts can cause serious injury or death: - Do not attempt to mount a tire without the proper equipment and experience to perform the job. - Always maintain the correct tire pressure. Do not inflate the tires above the recommended pressure. Never weld or heat a wheel and tire assembly. The heat can cause an increase in air pressure resulting in a tire explosion.
SERVICE MISCELLANEOUS Fuel c CAUTION: Handle fuel with care, it is highly flammable and can cause serious injury or death: - DO NOT refuel machine while you smoke, when machine is near an open flame or sparks, or when engine is running. STOP engine. - Fill fuel tank outdoors. - Prevent fires: clean oil, grease and dirt from machine. Clean up spilled fuel immediately. - Do not store machine with fuel in tank in a building where fumes may reach an open flame or spark.
SERVICE MISCELLANEOUS Octane Rating Regular grade 87 octane unleaded fuel is recommended for use in your tractor. Higher octane fuels will seldom make your tractor perform better. If your tractor develops a starting or performance problem immediately after use of new fuel, change supplier or fuel brand. If the problem still exists after switching fuel, see your John Deere dealer for service. Fuel Blends Fuels are blended to give peak performance during cold weather and warm weather.
SERVICE MISCELLANEOUS Using Fresh Fuel and Stabilizers The best thing you can do to ensure peak performance of your engine is to use “fresh” fuel. Your tractor’s engine will perform well with most good-quality fresh fuels regardless of additives. Any fuel will begin to deteriorate and evaporate over time and begin to form gum and varnish deposits in the fuel system. Help to avoid this by buying only enough fuel to last approximately 30 days or add fuel stabilizer immediately.
SERVICE MISCELLANEOUS • SAE Multipurpose EP Grease with 3 to 5 percent molybdenum disulfide. • SAE Multipurpose EP Grease. • Greases meeting Military Specification MIL-G-10924C may be used as arctic grease. 40°C 104°F 30°C 86°F 20°C 68°F 10°C 50°F 0°C 32°F - 10°C 14°F - 20°C - 4°F - 30°C - 22°F - 40°C - 55°C - 40°F NGLI Number 122°F NGLI Number Other greases may be used are: BIO-GREASE- • John Deere GREASE-GARD. GREASE- • John Deere High Temperature EP Grease.
SERVICE MISCELLANEOUS Care for Plastic and Painted Surfaces PLASTIC SURFACES The plastic parts on your tractor are made of a blend of polycarbonate and polyester materials. These parts are extremely strong and durable. Unlike painted metal, the plastic parts will never dent or rust. If the plastic parts get scratched, the color will remain the same since the color goes through the entire part. IMPORTANT: “Dry wiping” or wiping the plastic surface when it is dry will result in minor surface scratches.
SERVICE MISCELLANEOUS Avoid Damage: • “Dry wiping” or wiping the plastic surface when it is dry is a major source of minor surface scratches. • DO NOT wipe hood or other plastic parts unless wetted first. • DO NOT apply wax unless plastic surface has been thoroughly cleaned first. • DO NOT use abrasive materials, such as polishing compounds, to clean or to wax plastic surface. • DO NOT wax plastic surfaces without drying first. Hard-to-remove water spots will be left.
SERVICE MISCELLANEOUS PAINTED METAL SURFACES Correct Cleaning Care: Follow automotive practices to care for your tractor painted metal surfaces. Use a high-quality automotive wax regularly to maintain the factory look of your tractor’s painted surfaces. Repair: Minor Scratches (surface scratch): 1. Clean area thoroughly to be repaired. 2. Use automotive polishing compound to remove surface scratches. • DO NOT use rubbing compound to avoid removing paint. 3. Apply wax to entire surface.
REMOVING MOWER Removing Mower c CAUTION: Avoid injury, before removing mower from machine: STOP engine. Remove key. Wait for all moving parts to STOP.
