Cleaning the Spindle Pulleys

Mower Blade Care
WARNING: Before performing any main-
tenance, place the PTO switch in the
“OFF” position, engage the parking
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 yourself on
the sharpened blades.
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 already been sharp-
ened many times, or if any metal separation is present,
it is recommended that new blades be installed. New
blades are available at your authorized dealer.
The blades may be removed as follows.
Remove the deck from beneath the tractor, (refer
to Deck Removal on page 28) then gently flip the
deck over to expose its underside.
Use a 15/16 inch wrench to hold the hex nut on
top of the spindle assembly when loosening the
hex nut securing the blade. A block of wood may
be placed between the deck housing and the cut-
ting edge of the blade to help in breaking loose
the hex nut securing the blade. See Figure 35.
Figure 35
When reinstalling the blades, be sure they are
installed so that the wind wings are pointing
upward toward the top of the deck.
Reinstall the deck (refer to Deck Installation on
page 29).
