Cooling system - liquid cooled units

Gasoline units

DANGER: Never remove radiator cap or overflow reservoir cap when engine is hot. Pressurized hot steam and water may be released, causing serious burns or possible blindness. Fig. 4-10

Engine cooling is accomplished with circulated water and Ethylene Glycol mixture. The radiator is equipped with a pressure cap and overflow reservoir. Follow the information found in the engine owner’s manual for the recommended coolant solution.

Visually inspect the system daily prior to operating tractor. Be sure the engine is level. Check the coolant level only when the system is cold. Check the coolant level only at the overflow reservoir (Fig. 4-10). The cooling system is a closed type. Never open the radiator cap. Doing so may induce air into the cooling system and may cause overheating. The coolant level should be between the “H” and “L” marks.

Diesel Units

DANGER: Never remove radiator cap or overflow reservoir cap when engine is hot. Pressurized hot steam and water may be released, causing serious burns or possible blindness. Fig. 4-11

Engine cooling is accomplished with circulated water and Ethylene Glycol mixture. The radiator is equipped with a pressure cap and recovery tank. A 50-50 mixture is recommended for all season operation. This mixture provides freeze protection to -32 degrees F (-35 degrees C). Should temperatures fall below this level, additional Ethylene Glycol must be added to the mixture.

Visually inspect the system daily prior to operating tractor. Check coolant level in the recovery tank located to the left rear of the engine (Fig. 4-11). When the engine is cold the coolant should be up to the cold mark on the recovery tank. When the engine is hot the coolant should be up to the hot mark on the recovery tank. When adding coolant, pre-mix the solution before adding it to the recovery tank. It is not necessary to remove radiator cap for adding small amounts of coolant to system.

this manual for engine servicing, lubricating oil levels with quality and viscosity recommendations, bolt torques, etc. The engine warranty is backed by the manufacturer. Special attention should be paid to applicable data which will not be duplicated here.

IMPORTANT: Refer to the Kohler EFI engine owner’s manual for specific cleaning instructions.

Belts

Inspect belts frequently for wear and serviceability. Replace a belt that shows signs of severe cuts, tears, separation, weather checking and cracking, or burns caused by slipping. Slight raveling of belt covering does not indicate failure, trim ravelings with a sharp knife.

WARNING: If the pump belt fails, loss of control will occur especially when operating on a slope. If you lose steering control while operating the machine, place the steering control levers in the park brake position immediately. Inspect the machine and involve your Hustler dealer to resolve the problem before continuing to operate.

Inspect the belt pulley grooves and flanges for wear. A new belt, or one in good condition, should never run against the bottom of the groove. Replace the pulley when this is the case, otherwise belt will lose power and slip excessively.

Never pry a belt to get it on a pulley as this will cut or damage the fibers of the belt covering.

Keep oil and grease away from belts, and never use belt dressings. Any of these will destroy the belt composition in a very short time.

Mower blade maintenance

Check the mower blades daily, they are the key to power efficiency and well groomed turf. Keep them sharp, a dull blade will tear rather than cut
