Sharpen the blades on a grinder following pattern as shown "FIG. 45". Touch-up sharpening can be done
with a file.
Check the blades for balance following grinding. A commercial balancing tool is available through most
hardware supply stores, or balancing can be done by placing the blade on an inverted line punch or 1/2"
bolt. Blade should not lean or tilt. Spin the blade slowly, blade should not wobble. If blade is out of
balance, true it up before reinstalling.
Lay the blade on a flat surface and check for distortion "FIG. 46" and "FIG. 47". Replace any distorted
blade.
Do not re-use spindle bolts which have stripped, worn or undercut threads. Torque bolts to 118 foot-
pounds when reinstalling blades.
WARNING: When mounting blades, rotate them after installation to ensure blade tips do not touch
each other or sides of the mower.
WARNING: Failure to correctly torque the bolt may result in the loss of the blade which can cause seri-
ous injury.
WARNING: Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves and use extra
caution when servicing them.
Do not sharpen to original pattern (below).
It is easier to get a straight cutting edge following the
resharpening pattern shown above.
