IMPORTANT: Rotate the pin slightly toward the rear
of the tractor and release the pin into the hole provided.
Repeat the above steps on the right side of the
tractor.
Move the deck lift lever into the top notch on the
right fender to raise the lift arms out of the way.
Gently slide the cutting deck toward the front of the
tractor allowing the hooks on the deck to release
themselves from the deck stabilizer rod.
Gently slide the cutting deck (from the right side)
out from underneath the tractor.
CHANGING THE DECK BELT & PTO BELT
IMPORTANT: The V-belts found on your tractor are
specially designed to engage and disengage safely. A
substitute (non-OEM) V-belt can be dangerous by not
disengaging completely. For a proper working machine,
use factory approved belts.
WARNING: Be sure to shut the engine off,
remove ignition key, disconnect the spark
plug wire(s) and ground against the engine to
prevent unintended starting before removing
the belt(s). All belts on your tractor are subject
to wear and should be replaced if any signs of
wear are present.
WARNING: Avoid the possibility of a
pinching injury. Do not place your fingers on
the idler spring or between the belt and the
pulley while removing the belt.
To change or replace the deck belts on your tractor,
proceed as follows:
Lower the deck by moving the deck lift lever into the
bottom notch on the right fender.
Remove the belt guards by removing the self-
tapping screws that fasten them to the deck.
To ease in removing the belt in later steps, loosen,
but do not remove, the bolt which secures the
pivoting idler pulley to the idler bracket.
Insert a 3/8”-drive ratchet wrench (set to loosen)
into the square hole found in the idler bracket on the
left side of the deck’s surface. See Figure 20.
