work gloves to protect your hands when working

removed earlier. Use a torque wrench to tighten the flange
nut to between 37 foot-lbs. and 50 foot-lbs.
NOTE: Make certain that the drive belt is seated correctly
on the blade spindle and that it is riding smoothly on the
spindle sheaves and is not pinched between them. Repeat
the first three steps if the belt is pinched.

the surface of the axle bolt and the inner surface of the wheel
with light oil.

control lever, and if applicable, the blade adjustment lever, and
