SharpeningBlade
Remove the cutting blades byfollowing the
directions in the preceding section.
When sharpening the blades, follow the original
angle of grind as a guide. Itis 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 damage the
tractor and/or could break, causing personal injury.
BalancingBlade
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.
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 tractor is
in the operating position. Carefully align "star" on
blade with "star" on spindle. Secure with flange nut.
