Installing or removing blades
If the mower blades need to be installed, do the following:
1. The blade turns in a
counter clockwise direction when viewed from the bottom of
the deck. The cutting edge must be towards the direction of rotation. The lift wing of
the blades is closest to the deck and the cutting edge away from it
(see fig. 11) .
2. Install the cup washer (see fig. 11) over the blade bolt and secure the blade in place
as described above.
3. With a wrench, block the spindle and tighten the bolt to 103 lb. ft. (see fig. 12) .
4. To remove the blades reverse the procedure.
WARNING: Do not substitute blades or any bolt for the blade retaining bolt.
Company blades and blade retaining bolts are specially made for this application.
Using non original parts can effect the quality of cut and may also cause damage
to the mower.
DANGER: Proper torque must be used when tightening the blade retaining bolt. If
these safety precautions are not followed, the blade could come off during
operation and be thrown hundreds of feet from the mower.
Sharpening Blades
Blade sharpening is extremely important in order to get the best cutting results. Sharp
blades permit a high quality cut and also reduce HP thus lowering cost.
To sharpen blades, first remove them following the above instructions.
Place the blade in a vise and sharpen them by using a hand file or grinder.
Do not
sharpen the blades to a sharp cutting edge. The cutting edge should be between
1
/
64
”
to
1
/
32
” to prevent excessive pitting and dulling of the blades. Sharpen both ends of the
blade equally for balance and always maintain corners. Always keep all three blades
sharpened equally in order to maintain balance.
