Fuel Pump Priming
The Kohler diesel engine is equipped with a
mechanical fuel pump and in certain situations
(running out of fuel, changing the fuel filter, or other
fuel system maintenance) the fuel system may
need to be primed by removing air trapped in the
system. Fuel pump priming should be used if the
engine does not start after a couple of 10 second
cranking attempts.
NOTE: DO NOT
use prolonged cranking to prime
the fuel system as this may damage the starter
and shorten battery life.
Use the following procedure to prime the fuel pump
and purge air out of the fuel system:
1. Loosen the bolt on the fuel injection pump
return hose where it attaches to the fuel filter
housing as shown.

2. Turn ignition key to
ON
to open the electric
fuel shutoff valve (do not crank or run engine).
3. Repeatedly stroke the
Fuel Pump Primer
lever until fuel is flowing out of the return hose
fitting.

4. After bleeding the system, tighten the return
hose fitting bolt securely.
Steering Levers
Each drive wheel is controlled by its own indepen-
dent steering lever, for both steering function and
FORWARD/REVERSE
motion. The FSC lever
sets the maximum forward speed, and also sets
the for ward position of the steering levers. The
steering levers operate
only with a backward
pulling
move ment of the lever, which causes the
drive wheel for that lever to first slow down, stop,
and then reverse with a full backward lever stroke.
The levers are released to the
FORWARD
position
for “straight-ahead” ground travel.
NOTE:
Pushing forward on the steering levers will
not cause
any
change in tractor motion - there will
be no steering lever reaction and there will be no
machine damage.
Blade Clutch (PTO)
The blade clutch lever is located on the right side
of the seat behind the right fender and is used to
engage and disengage the mower blades. The
blade clutch lever has two positions. Pushing the
lever
DOWN engages
the PTO that drives the
mower blades. Pulling the lever
UP disengages
the PTO and engages the blade brake.
