Adjustments
Shift Rod (If Equipped)
If full range of speeds (forward and reverse)
cannot be achieved, adjust shift rod as follows:
1. Place shift lever in fastest forward speed
position.
2. Remove cotter pin (a) and washer (b)
from adjustment ferrule on shift rod and
pull it out from shift lever. See Figure 4-7.
Figure 4-7
3. Pivot shift bracket downward as far as it
will go. See Figure 4-8.
Figure 4-8
4. Rotate ferrule up or down on shift rod
as necessary until it lines up with upper
hole in shift lever. Refer to Figure 4-7

inset.
5. Insert the ferrule into the upper hole and
secure with the washer and cotter pin.
Shift Cable (If Equipped)
(b)
If full range of speeds (forward and reverse)
cannot be achieved, adjust shift cable as
follows:
1. Place shift lever in fastest forward speed
position.
2. Loosen hex nut (a) on shift cable index
bracket. See Figure 4-9.
3. Pivot bracket downward to take up slack

instructions on adjusting auger control cable.
Skid Shoes
Refer to Assembly & Set-up section (page 15)
for instructions on adjusting skid shoes.
Drive Control Lever
When drive control lever is released and in
disengaged "UP" position, cable should have
very little slack. It should NOT be tight.
NOTE:
If excessive slack is present in
drive cable or if unit's drive is disengaging
intermittently during operation, the cable may
be in need of adjustment.
Check adjustment of drive control leveras
follows:
1. With drive control lever released, push
unit gently forward. It should roll freely.
2. Engage drive control lever and gently
attempt to push the unit forward. The
wheels should not turn. The unit should
not roll freely.
3. If equipped with a shift lever, with drive
control lever released, move shift lever
back and forth between the R2 position
and the F6 position several times. There
should be no resistance in the shift lever.

If any of the above tests failed, the drive cable
is in need of adjustment. Proceed as follows:
1. Shut OFF engine. Refer to the Engine
Operator's Manual.
2. Loosen lower hex screw (a) on drive
cable bracket. See Figure 4-10.

Figure 4-10
3. Position bracket upward to provide
more slack (or downward to increase
cable tension).
4. Retighten upper hex screw.
5. Check adjustment of drive control lever
as described above to verify proper
adjustment has been achieved.
Chute Bracket (If Equipped)
If spiral at bottom of the chute directional
control is not fully engaging with chute
assembly, chute bracket needs to be adjusted.
To do so:
1. Loosen two nuts (a) which secure chute
