DECK MAINTENANCE
Cleaning And Blade Care
WARNING: Before performing any
maintenance, place the PTO switch in
the “OFF” position, engage the park-
ing brake lever, turn the ignition key to
the “OFF” position and remove the key
from the switch. When servicing the
mower deck, be careful not to cut your-
self 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 the thumb screws and belt
covers (Refer to Figure 63) to remove any
accumulation of grass clippings from around the
spindle pulleys and V-belt. Clean more often when
mowing tall, dry grass.
The cutting blades must be kept sharp at all times.
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 61), it is
recommended that new blades be installed.
Figure 61
When removing the blades, use a 1-1/8 inch
wrench to hold the head of the spindle bolt while
loosening the hex 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 nut. See Figure 62.
Figure 62
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 spindles to
prevent rust buildup.
DECK LUBRICATION
After every 10 hours of operation and/or before
putting the deck into winter storage, lubricate the
spindle assemblies and the spindle belt idler arm
with 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 covers. Use grease
liberally. Excess grease will be expelled from the
inverted upper seals of the spindle assemblies.
Listen for the muffled crackling noise of grease
being expelled through the seal to indicate the
spindle assembly is fully greased. Refer to Figure
63.
Apply grease to all other lube fittings after every 50
hours of operation. Refer to LUBRICATION GUIDE.
