routing the belt around the pulleys. Mount the motor
to the cutting unit with the bolts previously removed.
Note: Make sure the belt is positioned on the spring
side of the belt guide (Figure 65).
8. Reconnect the extension spring (Figure 65) to the
eye bolt and tension the belt as follows:
• When properly tensioned, the extension
spring (hook to hook) measurement should be
approximately 3.50 ±.25 inch (inside).
• Once the correct spring tension is attained,
adjust the stop bolt (carriage bolt) until there is
approximately .125 +.060/-.000 inch clearance
between the head of the bolt and the idler arm.

The traction pedal should reach full stroke at the same
time it makes contact with the stop. If it does not,
perform the following procedure:
1. Park the machine on a level surface, stop the engine,
and lower the cutting units to the floor. Remove the
ignition key.
2. Check the traction pedal stop adjustment. The
distance from the top of the stand to the top of
the stop must be 1-1/2 inch (38 mm) (Figure 68).
