4.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. Always grind each cutting blade edge equally to maintain proper blade balance. See Fig.
Figure
Caution: 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 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
