Did you select the correct drive belt for your
tractor? Using the wrong length belt may
cause premature bearing or belt failure.
STEP 10: (SEE FIGURE 10)
• Two different length drive belts are included with
your snow thrower. Tractors with manual attachment
clutches and single front deck suspension brackets use
the 56" drive belt with
#48138 printed on the outside of
the belt. DO NOT USE the other belt.
• Slightly loosen the hex bolt next to the flat idler pulley.
Install the drive belt down between the hex bolt and the
flat idler pulley with the flat side of the belt against the
pulley. Retighten the hex bolt.
• Loop the belt around the large v-pulley, placing it
between the v-pulley and the hex bolt next to the pulley.
Place the belt to the inside of the other flat idler pulley.
