SECTION IV. MAINTENANCE
A. CLEANING AND BLADE CARE
WARNING
Before performing any maintenance, place the
PTO switch in the “OFF” position, engage the
brake pedal lock, turn the ignition key to the
“OFF” position and remove the key from the
switch to avoid accidental starting and injury.
WARNING
When servicing the mower deck, be careful not
to cut yourself on the sharpened blades.
Clean the underside of the mower deck at the end of
the mowing season or when buildup of cut material on
the underside is noticed.
Once a month remove any accumulated grass clip-
pings from around the spindle pulleys and V-belt. More
often when mowing tall, dry grass. If necessary, re-
move the RH and LH belt covers by removing the six
hex nuts and lock washers.
The cutting blades must be kept sharp at all times.
NOTE
Sharpen the cutting edges of the blades evenly
so that the blades remain balanced and the
same angle of sharpness is maintained. If the
cutting edge of a blade has been sharpened to
within 5/8 inch of the wind wing radius (See
Figure 24), it is recommended that new blades
be installed. New blades are available at your
authorized dealer.
Figure 24
When removing the blades, use a 1-1/8 inch wrench to
hold the head of the spindle bolt while loosening the
hex flange nut securing the blade. A block of wood may
be placed between the deck housing and the cutting
edge of the blade to assist in removal of the hex flange
nut (Refer to Figure 25).
Figure 25
When reinstalling the blades, be sure they are installed
so that the wind wings are pointing upward toward the
top of the deck. Tighten the nuts to 90 to 110 ft-lbs.
(122 to 149 N·m).
After replacing the blades, apply grease to the
exposed threads at the bottom of the spindle bolts to
prevent rust buildup.
B. LUBRICATION
After every 10 hours of operation and/or before putting
the deck into winter storage, lubricate the spindle as-
semblies and the spindle belt idler arm using 251H EP
grease or an equivalent No. 2 multipurpose lithium
grease. The lube fitting for the outer spindles can be
accessed by removing the button plugs in the belt cov-
ers. Use grease liberally. Excess grease will be ex-
pelled from the upper spindle seals. When the spindle
is fully greased, the expelled grease will cause the top
spindle seal to give off a muffled crackling noise (Refer
to Figure 26).
Apply grease to all other lube fittings after every 50
hours of operation. Refer to LUBRICATION GUIDE -
