40” Mower PTO Belt Replacement
1. With the mower deck installed, park the tractor on a
smooth, level surface such as a concrete floor.
Disengage the PTO, engage the parking brake, shut
the engine off, and remove the key.
2. Remove the mower deck (see “Mower deck
removal”). Remove the belt covers.
3. Note the position of the idler pulley belt guides (E &
F, Figure 45) when installed. Loosen the idler pulley
capscrews and remove the belt from the idler pulleys
(D & G).
4. Install the new belt (B) as shown. When the mower
deck is installed on the tractor, the belt wraps around
the PTO clutch pulley (A), backside idler pulley (D),
mower deck drive pulley (C), and v-idler pulley (G) .
5. Return the idler pulley belt guides (E & F) to their
original positions and tighten the idler pulley
capscrews.
