circumferences as stated in Check the Tire
Pressures section in Maintenance.

smooth, hard surface such as concrete or asphalt.

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 links to either the “medium” or “heavy
duty” positions as shown in
Figure 25. The spring
anchor links are attached to the upper rear corner
of the hydro drive shields on the left and right
hand sides of the machine.
Note: In the “medium” or “heavy duty”
positions, the drive lever forces at the upper
handle will also be increased.
