IMPORTANT:
On 3-stage units, there
is an additional shear pin in the rear
accelerator.
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.
(a)
Shift Cable (If Equipped)
If full range of speeds (forward and reverse)
cannot be achieved, adjust shift cable as follows:
1. Place shift lever in fastest forward speed
(b)
position.
2. Loosen hex nut (a) on shift cable index
bracket. See Figure 4-9.
3. Pivot bracket downward to take up slack
in cable.
4. Retighten hex nut.
5. If further adjustment is necessary move
the shift cable to one of the alternate
holes in the shift cable index bracket.
Auger Control
Refer to Assembly & Set-up section for
(a)
instructions on adjusting auger control cable.
Skid Shoes
(b)
Refer to Assembly & Set-up section (page 13) for
instructions on adjusting skid shoes.
Drive Control (Models without Hydro
Transmission) (If Equipped)
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 lever as
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.
(a)
Figure 4-9
2. Loosen lower hex screw (a) on drive cable
bracket. See 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.

4. Retighten upper hex screw.
5. Check for excessive slack in drive control
cable. If necessary repeat Steps 2-4 to
re-adjust the drive control.
