IMPORTANT:
Each cutting blade edge has to be ground equally to maintain proper blade balance. A poorly balanced
blade will cause excessive vibration, may damage the tractor and/or result in personal injury.
5. Test the blade by balancing it on a round shaft screwdriver. Grind metal from the heavy side until it balances
evenly.
6. 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.
7. Use a torque wrench to tighten the blade spindle hex flange nut to between 70 and 90 foot-pounds.
8. Gently slide the cutting deck (from the right side) out from underneath the tractor.
