Maintenance Instructions
Drive Belts
Raise the body and inspect the condition of the four
(4) drive belts after every 25 hours of operation --
engine/PTO drive and ground drive. If the belts show
signs of cracking or deteriorating, the belts
should be replaced. Refer to REPLACING/REPAIR-
ING the Drive Belts in this section.
Spark Plugs
Every 200 hours, remove the spark plugs, inspect,
clean, and reset the gap (or replace with a new
plug). Clean spark plug with a wire brush. If the
electrodes are burned short or pitted, replace the
plug (refer to Specifications for the proper type of
replacement plug). Check the spark plug gap with a
wire-type feeler gauge and set the gap to 0.030 in.
(0.76 mm).
Reinstall and tighten to 18 ft-lb
·
(24.4 N
m). Both spark plugs should be replaced yearly.
Fuel Lines and Clamps
Every year, inspect the fuel lines from the tanks to
engine for deterioration or damage. Also, inspect the
fuel line clamps for tightness. Good preventive
maintenance calls for complete replacement of fuel
lines and clamps every two (2) years.
Blade Brake Action
It is important to check and maintain blade
brake action for safe operation of the ma-
chine.
Check the function of the cutter blade brake by
engaging the blade clutch (PTO), operating the
engine at full throttle, then disengaging the clutch
and measuring how quickly the blades stop. Watch
the rotation of the blade drive shaft as a visual indi-
cation that movement has stopped. If the brake is
working properly, all rotation will stop five (5)
seconds after disengagement of the clutch. If the
brake system malfunctions -- blades do not stop in
five (5) seconds -- repair the brake before operating
the mower.
