Mower Blade Care
Before performing any maintenance,
the parking brake lever, turn the ignition key to the
handling the blades. 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 sharpened 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
expose its underside.
Use a 2. ⁄
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. See Fig. 7-7.
When reinstalling the blades, be sure they are installed so 3.
that the wind wings are pointing upward toward the top of
the deck.
Reinstall the deck (refer to Deck Installation on page 28).5.
