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 reduces 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.
CAUTION: Unbalanced or warped blades can cause damage to the mower and/or
personal injury. Replace damaged blades before operating the mower. Sharpen
both ends of the mower blades equally or until the blade is balanced.
