Maintenance Instructions CLEANING
68
NOTE: Directing pressurized air or water from
the fan side of the radiator outward is recom-
mended to dislodge material packed on the out-
side of the cooling ns. 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 cool-
ant 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
location of the drain cocks). Also, drain the
coolant recovery tank.
3. If there is any indication of deposits or scaling
inside the radiator, use a commercial scale re-
mover and ush 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 rell 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 rst time the engine has been
operated after lling the coolant system (it would be
normal to add a little coolant after initial operation).
Grass Buildup in Mower Deck Housing
DANGER
Before raising or removing the mower
deck for cleaning, stop the engine, re-
move the ignition key, and disconnect the
electrical plug on the fuel shut-o
solenoid.
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-UP position 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 nally reached where cutting quality
deteriorates and clogging begins to occur
because of too much buildup on the baing and
housing.
