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 through the battery tray opening. See Figure 16.

•Remove the variable-speed pulley by loosening the hex bolt that affixes it to the transmission. Use a second wrench to hold the hex nut on the bottom side of the pulley.

•Slide the belt off of the variable-speed pulley as you lift the pulley up and out through the battery tray opening.

NOTE: Jacking the rear of the tractor up off the ground and securing it with jackstands at this point in the procedure will ease the following steps, but is not necessary.

•Remove the rear idler pulley from the double- idler bracket while unrouting the belt from around both the rear and the front idler pulley. Refer to Figure 16.

•On units equipped with an electric PTO, carefully unplug the tractor’s wire harness from the connector on the electric PTO clutch. See Figure 17.
