Adjustments
WARNING
Before checking mower, shut off PTO and
engine. Allow all moving parts to stop. Remove
ignition key, then disconnect the spark plug wire
and fasten it away from the spark plug.
4. Stop the engine, set the parking brake and raise the
seat deck. Loosen the jam nut (H) on end of cam
pivot shaft (G). If tractor creep had been in reverse,
turn adjusting nut (I) 1/8 - 1/4 turn clockwise when
viewed from right side of tractor.
If tractor was creeping forward, turn nut 1/8 - 1/4 turn
counterclockwise and lock jam nut
5. Lower seat deck and get in operator's seat. Start
engine and release parking brake. If tractor still
creeps, repeat step 4, turning adjusting (I) until creep-
ing stops.

LEVELING THE MOWER

If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. Make sure tire pressure is correct as speci-
fied in Checking Tire Pressure.
See Figure 26.
1. Turn both height adjustment handles (A) fully clock-
wise to the highest cutting height position.
2. Rotate the mower blades so the tips point straight for-
ward and backward.
3. Measure and note the distance from the front tip of
the center blade to the ground.
4. Measure the distances from the rear tips of the two
outside blades to the ground. They should be the
same. The rear measurement of the outside blades
should be 1/8" - 1/4" (3 - 6 mm) less than the mea-
surement for the front tip of the center blade. IF the
measurements are not correct, proceed to step 5.
5. Loosen the jam nuts (B). Remove the cotter pins and
then disconnect the eyebolts or yokes (C) from the
mower hitch.
6. Turning the eyebolts to change the length of the bail
assembly arms. Shorten the arms to decrease the
front height of the mower; lengthen the arms to
increase the front height of the mower. Be sure to
turn both yokes an equal number of turns for front-to-
back leveling.
7. Reinstall the yokes on the hitch. It is not necessary to
install the cotter pins yet. Check the blade tip mea-
surements as described in steps 3 & 4. Continue
adjusting the yokes until the front tip of the center
blade is 1/8" - 1/4" (3 - 6 mm) higher than the rear
tips of the side blades.

BLADE BRAKE ADJUSTMENT

Mower blades and mower drive belt should come to a
complete stop within five seconds after front PTO is
turned off.
1. With tractor in neutral, PTO disengaged and operator
in seat, start the tractor engine.
2. Look over the left-hand footrest at the mower drive
belt. Engage the PTO and wait several seconds.
Disengage the PTO and check the amount of time it
takes for the mower drive belt to stop.
3. If mower drive belt does not stop within five seconds,
perform the steps described under PTO Clutch
Adjustment. Repeat steps 1 and 2. If belt still does
not stop within 5 seconds, see your dealer.
