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.
