Maintenance Instructions

CLEANING

NOTE: Directing pressurized air or water from the fan side of the radiator outward is recommended to dislodge material packed on the outside of the cooling fins. DO NOT use cold water on a hot radiator.

WARNING

Radiator and engine parts can become extremely hot during operation. Wear gloves and avoid touching hot parts while cleaning the radiator screen and cleaning debris away from the engine and cooling system.

Flushing Radiator and Changing Coolant

Change engine coolant every year. Drain the coolant from the engine and radiator:

1.Remove the radiator cap.

2.Open the drain cocks on the engine block and radiator (see the Kubota Owner’s Manual for lo- cation of the drain cocks). Also, drain the cool- ant recovery tank.

3.If there is any indication of deposits or scaling inside the radiator, use a commercial scale re- mover and flush the cooling system thor- oughly before adding fresh coolant.

Use a pre-mixed 50/50 solution of antifreeze (ethyl- ene glycol) and distilled water to refill the cooling system.

IMPORTANT: The solution of antifreeze and water must be thoroughly pre-mixed before putting it in the engine. Adding pure antifreeze into the radiator may cause damage to the engine from overheating.

IMPORTANT: Maintain proper coolant level in the radiator and coolant recovery tank. The coolant level should be maintained between FULL and LOW marks on the coolant recovery tank. Recheck the coolant level after the first time the engine has been operated after filling the coolant system (it would be normal to add a little coolant after initial operation).

Grass Buildup in Mower Housing

DANGER

Before raising or removing the mower deck for cleaning, stop the engine, remove the ignition key, and disconnect the electrical plug on the fuel shut-off sole- noid.

1.Raise the deck lock lever handle on each side of the carrier frame and pull out to release car- rier frame for tilting action.

2.Using the carrier frame lift handle, raise deck to the TILT-UPposition and insert the deck hook into the tilt-up latch on the tractor body.

DANGER

Do not operate the mower with deck in tilt- up position. Do not move the tractor with the deck in the tilt-up position.

3.Clean grass buildup underneath the deck using a pressure washer (and scraper if required).

NOTE: While some degree of material buildup in the mower deck housing can be tolerated, a point is finally reached where cutting quality deteriorates and clogging begins to occur because of too much buildup on the baffling and housing.
