Mower Blade Care
_
ARNING:
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.
,_WARNING:
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 26) 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
cutting edge of the blade to help in breaking loose
the hex nut securing the blade. Refer to Figure 38.
•
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 blade nuts to 70-90 ft. ]bs.
•
Reinstall the deck (refer to Deck Installation
on
page 27).
