Lower Drive Belt
NOTE: Proper removal of the lower drive belt requires the removal of several tractor components. Read
through the following procedure prior to attempting it to determine if you feel you could successfully complete
it. If you don't, see an authorized MTD service dealer to have the belt changed.
IMPORTANT: Note the routing of the lower drive belt around both the pulleys and the belt keepers
BEFORE performing the following steps.
• Locate the variable-speed pulley by looking through the battery tray opening. See Figure 16.
• Remove the variable-speed pulley by loosening the hex bolt that secures it to the transmission. Use a
second wrench to hold the hex nut on the bottom side of the pulley.
• Slide the bett off of the variable-speed pulley as you lift the pulley up and out through the battery tray
opening.

to remove the upper drive belt from around it.
IMPORTANT: When remounting the engine
pulley, torque the center hex bolt to between 38 foot-
pounds and 50 foot-pounds.
• Remove the drive belt by feeding it from both
ends toward the front idler pulley on the
double-idler bracket. See Figure 16.

• Reassemble by following the above steps in
reverse order.
• Reroute the new bett around the pulleys and
bett keepers EXACTLY as the old one was
routed. Refer to Figure 16.
The drive pedal is properly adjusted when the hole
found in the double-idler bracket has approximately
1-3/8" of travel with ten pounds of pressure applied
to the drive pedal. See Figure 17.
