specifications.
SECTION 9: LUBRICATION
WARNING:
Before lubricating, repairing,
or inspecting, always disengage PTO, move
shift lever into neutral position, set parking
brake, stop engine and remove key to prevent
unintended starting.
Engine
Lubricate the engine with motor oil as instructed in the
Engine
Owner’s Manual packed with your unit.
Pivot Points & Linkage
Lubricate all the pivot points on the drive system,
parking brake and lift linkage at least once a season
with light oil.
Transmission
The hydrostatic transmission is sealed at the factory.
Oil level cannot be checked nor can the oil be changed.
Front Wheels
Each of the front wheel axles is equipped with a grease
fitting. Lubricate with a grease gun after every 25 hours
of tractor operation.
Rear Wheels
The rear wheels should be removed from the axles
once a season. Lubricate the axles and the rims well
with an all-purpose grease before re-installing them.
SECTION 10: SERVICE
TIRES
WARNING:
Never exceed the maximum
inflation pressure shown on the sidewall of
the tire.
The recommended operating tire pressure is 10 psi for
the rear tires and 14 psi for the front tires. Refer to the
tire sidewall for exact tire manufacturer’s recommended
or maximum psi. Do not overinflate. Uneven tire
pressure could cause the cutting deck to mow
unevenly.
CUTTING BLADES
WARNING:
Be sure to shut the engine off,
remove ignition key, disconnect the spark
plug wire(s) and ground against the engine to
prevent unintended starting before removing
the cutting blade(s) for sharpening or
replacement. Protect your hands by using
heavy gloves or a rag to grasp the cutting
blade.
WARNING:
Periodically inspect the blade
adapter and/or spindle for cracks or damage,
especially if you strike a foreign object.
Replace immediately if damaged
.
The blades may be removed as follows.
•
Remove the deck from beneath the tractor, (refer to
DECK REMOVAL) then gently flip the deck over to
expose its underside.
•
Place a block of wood between the center deck
housing baffle and the cutting blade to act as a
stabilizer. See Figure 20.
•
Use a 15/16" wrench to remove the hex flange nut
that secures the blade to the spindle assembly. See
Figure 20.
To properly sharpen the cutting blades, remove equal
amounts of metal from both ends of the blades along
the cutting edges, parallel to the trailing edge, at a 25°
to 30° angle. See Figure 21.
IMPORTANT:
If the cutting edge of the blade has
already been sharpened to within 5/8" of the wind wing
radius, or if any metal separation is present, replace the
blades with new ones. See Figure 21.
