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 70).
8. Reconnect the extension spring (Figure 70) 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

Adjusting the Traction Pedal
Linkage
With the traction switch in the mow position (low
speed), the traction pedal should contact the stop just
before the pump is at full stroke to prevent any damage
to the pump. 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. Depress the traction pedal until it is at full stroke
(Figure 73). The jam nuts may have to be loosened
and the stop lowered to attain full stroke.
