Installation
Adjusting the Deck Slope for Transport
To extend PTO drive belt life and provide adequate
transport height, the deck slope in transport should be
adjusted. Three steps accomplish this: 1) Making
sure the lift arm cams are in the same position, 2)
Measuring blade slope in its front and rear positions
and 3) Making adjustments if the blade slope is not
within specification.
IMPORTANT: Failure to adjust for transport
can result in drive belt failure.
IMPORTANT: Failure to adjust for transport
can result in insufficient transport height.
1. Check to see that both adjustment cams are
oriented with the indicator toward the pivot point
at the rear of the tractor (Fig. 17).

2. If they are not, park the machine on a level
surface, set the parking brake, lower the
attachment lift to take pressure off the cams, and
turn the ignition key to "STOP" to stop the
engine. Remove the key.

POTENTIAL HAZARD
The "scissor" formed by the mower
mounting brackets and the attachment lift
arm is dangerous.
WHAT CAN HAPPEN
Hands and fingers can get caught between
the mower parts and the tractor and be
injured.
HOW TO AVOID THE HAZARD
Keep hands away from moving parts while
operating the attachment lift.
Set the parking brake, lower the
attachment lift, turn the ignition key to
"STOP" to stop the engine, and remove the
key before making any adjustments.
3. Loosen the nuts on the cams, rotate the cams to
the proper position, then tighten the cam nuts.
4. Start the tractor, raise the attachment lift and turn
the ignition key to "STOP" to stop the engine.
Remove the key.
5. Check the slope of one of the blades (Fig. 14).
A. Measure the distance from the front tip of
the blade to the flat surface.
B. Carefully rotate the blade tip until it is in
the rear position.
C. When the blade tip is in the front position,
it should be approximately 1/4" (7 mm)
lower than when it is in the rear position.
6. If it is not, start the tractor, lower the attachment
lift to take pressure off the cams, and turn the
ignition key to "STOP" to stop the engine.
Remove the key.
7. Loosen the cam nuts and equally rotate the
left–hand and right–hand cams down to raise the
front of the deck, or up to lower the front of the
deck. Tighten the nuts.
