Changing The Deck Belt(S) - MTD 608 Operator's Manual

CHANGING THE DECK BELT(S)

All belts on your tractor are subject to wear and should be replaced if any signs of cracking, shredding or
rotting are present.
IMPORTANT:
The V-belts found on your tractor are specially designed to engage and disengage safely. A
substitute (non-OEM) V-belt can be dangerous by not disengaging completely. For a proper working machine,
use factory approved belts.
To change or replace the deck belt(s) on your tractor, proceed as follows:
NOTE:
Removing the deck from the tractor as instructed earlier in this section will ease the following steps,
but is not necessary.

• Lower the deck by moving the lift lever into the bottom notch on the right fender.
• Remove the belt guards by removing the self-tapping screws that fasten them to the deck surface.
• Move the PTO lever into the disengaged (OFF) position to relieve tension on the belt.
• Remove the PTO belt from around the bottom portion of the engine pulley and from around the two
idler pulleys found on the PTO engagement plate. See Figure 14.
• Route the new belt as shown in Figure 14, around the deck pulleys, idler pulleys and engine pulley.
