Mower blade removal
Use a 15/16" wrench to remove the 5/8" cap screw holding the blade to
the spindle shaft from underneath.
Sharpen the blades on a grinder following pattern as shown (Fig. 9-15).
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
5/8" 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. 9-16 and 9-
17). Replace any distorted blade.
Do not re-use spindle bolts which have stripped, worn or undercut
threads. Torque bolts on spindles to 118 foot-pounds (160.01Nm) when
reinstalling blades.
IMPORTANT: The blade sail (curved part) must be pointing upward
toward the inside of the deck to ensure proper cutting.
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 serious injury.
WARNING: Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution when servicing
them.
