Engine PTO Drive Belt (3 Groove Power Band)
1. To remove the engine PTO drive belt:
a. Remove the jackshaft drive belt from its
idler pulley (by pushing down on cold start
lever) and let the belt drop down out of the
way.
NOTE: Step (a) is not essential to removing
the PTO belt, but it makes more room to work
with the PTO belt.
b. Loosen the brake band adjustment nut to
allow the clutch idler pulley to drop down
against the frame. This provides maxi-
mum looseness of the belt to assist
removal.
c. Remove the PTO drive belt by “walking”
the belt off of the engine and PTO pulleys
one groove at a time until the belt is com-
pletely removed.
2. Install the PTO drive belt by reversing the re-
moval procedure. Refer to ADJUSTMENTS of
Blade Clutch (PTO) in this section to check
and make the following adjustments:
a. Adjust clutch disengagement (brake band
adjustment) and check brake action.
b. Adjust clutch engagement for proper belt
tension.
