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.
