PTO Belt Replacement
1. Park the tractor on a smooth, level surface such as a
concrete floor. Disengage the PTO, engage the
parking brake, turn off the engine, and remove the
ignition key.
2. Remove the hairpin clip and clevis pin and remove
the deck lift foot pedal. Lift the floor plate to gain
access to the PTO drive belt.
3. Release the spring tension on the PTO drive belt
with a wrench on top of the idler pulley (A, Figure
41).
4. Slide the drive belt over the edge of the idler pulley.
Drop the belt from the PTO clutch pulley groove.
NOTE: Releasing the belt tension may loosen the hard-
ware fastening the idler pulley to the idler arm. Make
sure to re-tighten the hardware if this occurs.
5. Remove the old belt and replace with a new one.
Make sure the V-side of the belt runs in the pulley
grooves (Figure 42).
6. Install the drive belt on the PTO pulley, the arbor pul-
ley and V-sided idler pulley. Release the spring ten-
sion on the idler pulley (A, Figure 41) and install the
belt onto the pulley.
7. Run the mower under no-load condition for about 5
minutes.
