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 Kohler 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 lev-
el 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
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.
Deck Secured in 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.
4. Lower the deck to the normal operating position
and re-engage the deck lock levers.
DANGER
Before raising or removing the mower
deck for cleaning, stop the engine, re-
move the ignition key, and disconnect the
spark plug wires.
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.
CAUTION
Do not operate machine with deck tilt-up
pivot joint unlocked.
