BLADE SHARPENING
Use gloves when handling mower blades. Blades can be very
sharp.
IMPORTANT! When sharpening blades, be sure material removed is
equal on both sides of the blade. Unbalanced blades will cause
excessive vibration leading to cracks in machine components.

Clean all material from the blade prior to sharpening and
balancing.

Grind or file blades following original pattern as shown.

Sharpen to a razor edge. Do not sharpen back side of blade.
Use the supplied cone balancer to verify blade balance. When
the blade is correctly balanced, the blade will remain horizontal.
SPINDLE SERVICE
Each spindle is supported by two ball bearings. No adjustment of
clearance is required. Running clearance is pre-set during assembly
by
tightening the 1” NF left hand nut on top of the pulley.
Periodically inspect blade spindles by grasping pulley, and moving
from side to side. If any free play is noted, replace or repair.
SPINDLE ASSEMBLY REMOVAL

pulley.

the hole in the deck.
