CUTTING BLADES
A. Removal For Replacement Or Sharpening
WARNING: Be sure to disconnect and
ground the spark plug wire(s) and remove
ignition key before working on the cutting
blade to prevent accidental engine starting.
Protect hands by using heavy gloves or a
rag to grasp the cutting blades.
1. Remove the hex flange nut which holds the
blade to the blade spindle.
2. Remove the blade from the spindle.
B. Sharpening
Remove the cutting blades by following the
directions of the preceding section.
When sharpening the blades, follow the original
angle of grind as a guide. It is extremely important
that each cutting edge receives an equal amount of
grinding to prevent an unbalanced blade. An
unbalanced blade will cause excessive vibration
when rotating at high speeds, may cause damage to
the mower and could break, causing personal injury.
The blade can be tested for balance by balancing it
on a round shaft screwdriver. Remove metal from
the heavy side until it balances evenly.
C. Reassembly
When replacing blades, be sure to install the blade
with the side of the blade marked ‘‘Bottom’’ (or with
part number) facing the ground when the mower is in
the operating position. Carefully align “star” on blade
with “star” on spindle. Secure with hex flange nut.
