Mower blade removal
Use a 15/16" wrench to remove the 5/8" cap screw
holding blade to spindle saddle from underneath.
Sharpen the blades on a grinder following pattern as
shown (Fig. 4-10). 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. 4-11 and 4-12). 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 serious injury.
