HYDRO PUMP SPRING TENSION SETTING
5.2.11 Park Brake Adjustment:
a) Shut off engine and wait for all moving parts to stop.
b) Disengage the park brake.
c) Remove the hairpin in the lower park brake linkage. Turn the linkage in
the yoke until there is 3/16” (.48 cm) to 1/4” (.64 cm) clearance between
the park brake tire bars and the tires with the park brake disengaged. Re-
install the hairpin.
6. WASTE DISPOSAL
6.1 MOTOR OIL DISPOSAL
Engine oil and hydraulic oil are both pollutants to the environment. Dispose of used oil
at a certified recycling center or according to your state and local regulations.
7. TROUBLE SHOOTING
7.1 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.
7.2 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 on each blade, the axle positions on each side of the
unit, and the spacers on each front caster wheel. They must be equal.
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” (4.8
mm), or one blade width from being in line.)
7.3 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 PTO engagement adjustment (See
Section 5.2.5.).
7.4 ENGINE WILL NOT START.
a) For 15 HP Kawasaki units: 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 PTO is disengaged and the PTO switch is depressed.
