5. 

To properly sharpen the cutting blade, remove equal amounts of metal 

from both ends of the blade along the cutting edges, parallel to the trailing 

edge, at a 25°- to 30° angle. Always grind each cutting blade edge equally to 

maintain proper blade balance. See Figure 25.

6. 

Test the blade’s balance using a blade balancer. Grind metal from the heavy 

side until it balances evenly.

  WARNING

A poorly balanced blade will cause excessive vibration, may damage 

the tractor and/or result in personal injury.

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 tractor is in the operating position.

  CAUTION

 Use a torque wrench to tighten the hex bolt to between 450-600 in-lbs.
