4. If the unit tracks to one side or the other, turn the quick track knob .
Turn the knob right to “steer” right, turn the knob left to “steer” left.
5.2.10 Hydro Pump Spring Tension Setting:
a) 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.
b) For a heavier drive setting, relocate the spring anchor links to either the
“medium” or “heavy duty” positions as shown in Figure 18. 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.

6. TROUBLE SHOOTING
6.1 MOWER TRACKS TO LEFT OR RIGHT.
a) Check the drive tire pressures and circumferences. See 5.1.11.
b) Turn knob on the right hydro control linkage in the direction in which the
mower needs to be adjusted. Turn the knob in 1/4 turn increments until
the mower tracks correctly.
6.2 MOWER CUTS UNEVENLY.
a) Check the drive tire pressures and circumferences. See 5.1.11. A more
uniform cutting height may be obtained with higher tire pressure on rough
terrain. A lower tire pressure provides more flotation.
b) Check blade spacers, they must be equal on each blade.
c) Check caster mounting brackets to be sure all bolts are tight.
d) Check blades tip to tip for straightness. (They should be within 3/16”, or
one blade width from being in line.)
6.3 BLADES DO NOT STOP WHEN DISENGAGED.
a) Check the blade brake adjustment. (See Section 5.2.6)
b) Check the belt guide under rear deck to make sure they are properly set
(See Section 5.2.7) and check the blade engagement adjustment (See
Section 5.2.3.).
6.4 ENGINE WILL NOT START.
a) Check that the key switch is in the “Run” position.
b) Check that the choke is in the “ON” position for a cold engine or in the
“OFF” position for a warm engine. See 4.3.2.
NOTE: Kawasaki engines may need to be choked even when warm.
c) Make sure speed control lever is in the “true neutral” position. (See 5.2.9).
d) Check that the blades are disengaged and the blade switch is depressed.
