Loosen the jam nut on the stop bolt, then turn the
stop bolt counterclockwise to make it longer.
Recheck the tracking and fine tune the adjust-

TRANSMISSION DRIVE BELT
If the transmission drive belt becomes worn and
causes the drive transmissions to slip, the drive belt
must be replaced. To replace the drive belt, proceed
as follows:
Remove the deck drive belt from the PTO clutch
on the bottom of the engine following the instruc-
tions in Deck Removal, SECTION 5: MOWER

From beneath the rear of the tractor, insert a 3/8

idler bracket. See Figure 33.
