It is important to maintain proper adjustment of the Steering Linkage so that the each Handle reaches
Neutral at the same position. Figure 30 shows the location of the Pump Linkage on the Hydraulic
Pumps, which you can adjust to achieve the correct setting.

freely.
2. Loosen the Hex Socket Cap Screw at the
bottom of the Pump Linkage on each
Hydraulic Pump (Figure 30).
3. Start the Engine and run it at 3/4 Throttle
setting.
4. Rotate the Pump Linkage forward and
backward to find the Neutral position.
