Remove the mower deck from the tractor as follows:
1.Move the tractor to a level surface, disengage the PTO, stop the engine, and set the parking brake.
2.Move the deck gauge wheels to their highest setting (lowest deck setting).
3.Remove the ‘V’ belt from the PTO pulley, located on the bottom of the engine, using one of the following two methods.
WARNING: The muffler at the rear of the tractor may be extremely hot, and could cause serious burns. Use extreme caution when near the muffler. Allow the muffler to fully cool before removing the belt from the PTO pulley.

•Using the deck lift handle, raise the deck to the position that provides the most horizontal run of the belt between the deck idler pulleys and the PTO pulley on the bottom of the engine.
•Working from the middle of the tractor, pivot the idler bracket and movable idler pulley rearward away from the backside of the ‘V" belt just far enough to lift the belt up and over the idler pulley. See Figure 29.

•Sitting behind the tractor facing forward, reach beneath the tractor to grasp the belt at the front of the PTO pulley.
WARNING: Use caution to prevent pinching your fingers when rolling the belt off the PTO pulley.
•Pull the left side of the belt rearward and down- ward while manually turning the PTO pulley to the right until the belt rides out onto the edge of the lower sheave of the pulley. NOTE: If pulling the right side of the belt, turn the pulley to the left.
