4. Rotate ferrule up or down on shift rod as necessary until it
lines up with upper hole in shift lever (Figure 57 inset).
5. Insert the ferrule into the upper hole and secure with the
washer and cotter pin.
DRIVE CONTROL (NON-HYDRO MODELS) (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 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 snow blower gently
forward. It should roll freely.
2. Engage drive control lever and gently attempt to push the
snow blower forward. The wheels should not rotate or 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 fail, the drive cable is in need of
adjustment. Proceed as follows:
1. Shut OFF engine, remove safety key or disconnect spark plug
wire. Refer to the Engine Operator's Manual.

2. Loosen lower hex screw (a) on drive cable bracket (b)
(Figure 58).
1. Position drive cable bracket upward to provide more slack (or
downward to increase cable tension).
2. Re-tighten lower hex screw.
3. Check adjustment of drive control lever as described above to
verify proper adjustment has been achieved.
DRIVE CONTROL (HYDRO MODELS) (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 drive is
disengaging intermittently during operation, the cable may be in
need of adjustment.
1. Shut OFF engine, remove safety key or disconnect spark plug
wire. Refer to the Engine Operator's Manual.
2. Loosen upper hex screw (a) on drive cable bracket (b)
(Figure 59).
3. Position bracket upward to provide more slack (or downward
to increase cable tension).
4. Re-tighten upper hex screw.
5. Check for excessive slack in drive control cable. If necessary
repeat Steps 2-4 to re-adjust the drive control.
