3. Run the unit and observe the tracking on a level,
smooth, hard surface such as concrete or asphalt.

Adjusting the Spring Anchor
Links
For medium or heavy duty drive conditions, such as
operating 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.
1. Disengage the PTO and set the parking brake.
2. Stop the engine and wait for all moving parts to stop
before leaving the operating position.
3. For a heavier drive setting, relocate the spring anchor
links to either the medium or heavy duty positions
(Figure 43). The spring anchor links are attached to
the upper rear corner of the hydro drive shields on
the left and right sides of the machine.
Note: In the medium or heavy duty positions, the
drive lever forces at the upper handle will also be
increased

Checking the Tire Pressure
Check the pressure at the valve stem after every
50 operating hours or monthly, whichever occurs first
(Figure 44).
Maintain the air pressure in the rear tires at 12-14 psi
(83-97 kPa). Uneven tire pressure can cause an uneven
cut.
Note: The front tires are semi-pneumatic tires and do
not require air pressure maintenance.
