3.
Run the unit and observe the tracking on a level,
smooth, hard surface such as concrete or asphalt.
4.
If the unit tracks to one side or the other, turn the
quick track knob. Turn the knob right to steer right

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 45). 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
Service Interval:
Every 50 hours/Monthly (whichever
comes first)—Check the tire pressure.
Check the pressure at the valve stem (Figure 46).
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.
