Instructions below are for extending the hitch out 4".
Reverse procedure to adjust hitch in.
1. Support rear cross beam with support blocks or jack
stands at a height that will support the unit
approximately level when unhooked from the tractor.
2. Raise park stand (#1) so that it will not be supporting
the unit when unhooked from the tractor.
3. Unhook Snow Blower from the tractor. Refer to
on page 21 for detailed
instructions.
4. Remove bolt (#5) from upper hitch (#4) and bolts (#5)
from lower left and right arms (#2 & #3).
5. Slide 3-point hitch away from the Snow Blower 4" to
align hole “A” at the top with hole in upper hitch (#4)
and holes “B” at the bottom with holes in lower
arms (#2 & #3).
6. Reinsert the five 3/4"-10 x 4 1/2" GR5 bolts (#5) with
four flat washers (#7) as shown. Secure bolts with
hex flange locknuts (#6). Tighten locknuts to the
correct torque.
Roller Chain
Refer to Figure 3-8:
IMPORTANT:
The rear of the Snow Blower must be
supported with support blocks or jack stands to
make this adjustment. Park stand must be raised.
IMPORTANT:
Make sure roller chain (#8) is beneath
take-up idler (#7) and not above.
1. Remove cap screws (#3) and idler guard (#1). Keep
guard and guard hardware for reattachment.
2. Loosen 5/8" cap screw (#2) and push down on idler
sprocket (#7) until vertical movement in the middle of
bottom chain has 3/8" to 1/2" slack.
3. Hold sprocket in this position and tighten 5/8"-11 cap
screw (#3) to the correct torque.
4. Attach idler guard (#1) with existing 5/16"-18 GR5
hex head cap screws (#3),4 flat washers (#6), spring
lock washers (#5), and hex nuts (#4). Tighten hex
nuts to the correct torque.

IMPORTANT:
Tighten roller chain until bottom chain
has 3/8" to 1/2" slack. Do not tension roller chain too
tight. An over-tensioned roller chain will accelerate
chain wear and sprocket wear.
