WARNING! If the cutting edge of the blade has
previously been sharpened, or if any metal
separation is present, replace the blades with new
ones.
WARNING! A poorly balanced blade will cause
excessive vibration, may cause damage to the
tractor and/or result in personal injury.
5. Test the blade’s balance using a blade balancer. Grind
metal from the heavy side until it balances evenly.
NOTE: When replacing the blade, be sure to install the
blade with the side of the blade marked ‘‘Bottom’’ (or with
a part number stamped in it) facing the ground when the
mower is in the operating position.
CAUTION! Use a torque wrench to tighten the
blade spindle hex flange nut to between 70 lbs-ft
and 90 lbs-ft.
Changing the Transmission Drive Belt
NOTE: Several components must be removed and special tools
(i.e. air/impact wrench) in order to change the tractor’s drive belt.
See an authorized Troy-bilt Service Dealer to have your drive belt
replaced or phone Customer Support as instructed on page 2 for
information on ordering a Service Manual.
