To properly sharpen the cutting blades, remove equal amounts of metal
from both ends of the blades along the cutting edges, parallel to the trailing
edge, at a 25° to 30° angle.
IMPORTANT: If the cutting edge of the blade has already been sharpened to
within 1-5⁄8" from the edge, or if any metal separation is present, replace the
blades with new ones. See Figure 28.
If the cutting edge of the blade has previously been sharpened, or if any
metal separation is present, replace the blades with new ones.
A poorly balanced blade will cause excessive vibration, may cause damage
to the tractor and/or result in personal injury.
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.
Use a torque wrench to tighten the blade spindle hex flange nut to
between 70 ft-lbs and 90 ft-lbs.
Changing the Deck Belt
Be sure to shut the engine OFF, remove the key, disconnect the spark plug
wire(s) and ground against the engine to prevent unintended starting
before removing the belt.
