Note:
The proper mower belt tension is 10-15 lbf.
(44-67 N) with the belt deflected 1/2 inch (13 mm)
halfway between the pulleys (Figure 34).

Note:
The clearance should be 1/16—1/8 inch
(2-3 mm).
10. Remove the hairpin cotter and the clevis pin from
the bell crank.
11. Rotate the clevis clockwise on the rod to increase
the clearance; rotate it counterclockwise to decrease
it (Figure 35).
12. Disengage the blade control (PTO) lever.
Note:
If the assist arm does not contact the front
stop on the mower deck (Figure 36), adjust the clevis
to bring the bell crank closer to the transmission
output shaft (Figure 35).

13. Check the belt guide under the engine frame for the
proper adjustment (Figure 33).
Note:
The distance between the belt guide and the
mower belt should be 1-1/4 inch (32 mm) when
you engage the mower belt (Figure 37). Adjust the
mower belt as necessary. The disengaged belt should
not drag or fall off the pulley when the guides are
properly adjusted.
