NOTE:
There is a small yellow wire connected to a
spring switch on the underside of the shift cover panel.
Be careful not to damage it when removing the panel.
•
Remove the hairpin clip which secures the
disengagement rod to the stabilizer shaft assembly.
•
Pull the rod toward the rear of the tractor (to take up
slack), then thread the rod inward or outward
(usually only one or two turns) until the rod lines up
as precisely as possible with the hole in the
stabilizer shaft.
NOTE:
Threading the disengagement rod outward
(toward the rear of the tractor) provides for more belt
tension. Threading the disengagement rod inward
provides for less belt tension.
•
Reinsert the rod in the stabilizer shaft and re-
secure it with the cotter pin removed earlier.
Check the adjustment by placing the deck engagement/
lift lever in the BLADES STOP position. The deck
should move up and forward, allowing the belt to
become loose.
•
Reassemble the shift cover panel.
•
Start the tractor’s engine and test the deck
engagement/lift lever to be certain the blades fully
disengage when in the BLADES STOP.
•
Repeat the adjustment procedure if necessary.
Parking Brake Adjustment
WARNING:
Never attempt to adjust the
brakes while the engine is running. Always
place the deck engagement/lift lever in the
BLADES STOP position, shift into neutral, set
parking brake and remove the key to prevent
unintended starting.
If the tractor does not come to a complete stop when
the clutch-brake pedal is completely depressed, or if
the tractor’s rear wheels can roll with the parking brake
applied, the brake is in need of adjustment. The brake
disc can be found on the right side of the transmission
in the rear of the tractor. Adjust if necessary as follows:
•
Looking at the transmission from the right side of
the tractor, locate the compression spring and
brake disc. See Figure 16.
•
Loosen, but do NOT remove, the hex nut found on
the right side of the brake assembly. See Figure 16.
•
Using a feeler gauge, set the gap between the
brake disc and the brake puck at .011".
•
Re-tighten the hex nut loosened earlier.

Speed Control Adjustment
NOTE:
When operating the unit initially or after
replacing the belts, there will be little difference
between the highest two speeds until after the belts
have gone through a break-in period and have seated
themselves into the pulleys.
If the full range of speeds cannot be obtained on your
unit, adjust the speed control as follows.
•
Unthread the shift knob and remove the two flange
screws which secure the shift cover panel in place.
Refer to Figure 14.
•
Remove the shift cover panel and locate the speed
control rod. See Figure 17.
NOTE:
There is a small yellow wire connected to a
spring switch on the underside of the shift cover panel.
Be careful not to damage it when removing the panel.
