Maintenance

Hydro Pump Spring Tension Setting

1.For medium or heavy duty drive conditions such as operation with a sulky on steep slopes, a higher spring force may be required on the hydro pump control arms to prevent the drive system from stalling.

2.For a heavier drive setting, relocate the spring anchor link as shown in Figure 13. The spring anchor links are located under the engine deck on the left and right hand sides.

Note: In “medium” or “heavy duty” positions, the drive lever forces at the upper handle will also be increased.
