Installing the Blower Pivot Support
1.
Slide the pivot support over the threaded stud welded
to the front of the mower near the discharge opening.
Use the inside slot on the pivot support so that the
pivot support is closest to the discharge opening
(Fig. 4).
Note:
If necessary, remove any hardware in the mower
deck interfering with the pivot support. Retain all
hardware.
2.
Align the pivot support parallel with the front curved
edge of the mower deck and tight up against the top of
the mower. (Fig. 4).
3.
Secure the pivot support to the mower with a
5/16 x 3/4 inch bolt and a 5/16 inch flange nut (Fig. 4).
4.
Place a 3/8 inch jam nut and 3/8 inch washer snug onto
the stud. Do not overtighten the jam nut (Fig. 4).
5.
Remove the mower belt cover from the right side
pulley (Fig. 4).
Note:
Save all parts and hardware for use when removing
the blower.

Pull on the mower idler assembly to release belt
tension and remove the blade drive belt from the right
side pulley; refer to the machine
Operator’s Manual
for instructions.
Note:
Block the blade with a piece of wood to stop it from
turning while you remove the pulley nut. If the blade
slips, hold the hex portion of the spindle with a wrench.
2.
Remove the nut and lock washer from the right–hand
blade spindle. Remove the single pulley.
Note:
When the nut is removed the shaft is free to drop
out of the spindle. Be sure to support the spindle and blade
from the bottom side.
3.
Slide the new double pulley onto the spindle shaft with
the small pulley, facing up. Secure it with the
previously removed 5/8 inch lock washer and nut (Fig.
5).
4.
Tighten the nut to 50–75 ft. lb. (68–101 Nm).
5.
Install the existing mower belt onto the bottom pulley
(Fig. 5).
