Belt Removal/Replacement - MTD "A" Series Professional Shop Manual

A and B series mowers

Belt removal/replacement

The single speed and the variable speed mowers use the same transmission. When the drive control bail is oper-
ated, it pulls on the drive cable. As the drive cable starts to pull the clutch lever on the transmission, it engages the
clutch. As the cable continues to pull, it tilts the transmission to put tension on the drive belt. On the single speed ver-
sion, it is one solid pull that fully engages the drive belt. On the variable speed version, the amount of tension is con-
trolled by how much the cable is pulled.
To remove/replace the belt:
1. Remove the blade by following the steps described
in the blade section of this chapter.
NOTE: Keep the mower on its side.
2. Remove the engine mounting screw that secures
the engine baffle using a 1/2" wrench.
See Figure 2.6.
3. Slide the neck of the baffle out of the deck opening.
4. Rotate the baffle until the opening in it lines up with
the blade adapter. See Figure 2.7.
5. Remove the baffle.
6. Remove the blade adapter while slipping the belt off
of the pulley.
NOTE: There may or may not be washers and/or a
spacer above the blade adapter, depending
on the engine installed on the mower. If
there are, note the order they came off so
they can be installed the same way.
