Cutting Deck Removal
NOTE: Models equipped with a 38-inch deck have one deck idler
pulley. Models equipped with a 42- and 46-inch deck have two
deck idler pulleys.
To remove the cutting deck, proceed as follows:
1. Place the PTO (Blade Engage) lever in the disengaged (OFF)
position and engage the parking brake.
2. Lower the deck by moving the deck lift lever into the
bottom notch on the right fender.
3. Removing the self-tapping screw (A) that secures the belt-
keeper rod from around the tractor's engine pulley, then
remove the belt keeper rod (B). See Fig. 7-1.
Note: Make a mental note what hole the other end of the belt-
keeper rod is inserted in for reinstallation purposes.
