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).

5.Return the idler pulley belt guides (E & F) to their original positions and tighten the idler pulley capscrews.
