unit after 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 64).
8. Reconnect the extension spring (Figure 64) 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

Adjusting the Traction Pedal

Linkage

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 67). Loosen the nuts and adjust, as
required.
