1. Remove the cutting deck from beneath the tractor as
instructed in your tractor's Operator's Manual.
2. Gently flip the deck over to expose its underside.
3. Stablize one of the cutting blades with a blade lock tool or
a block of wood. See Figure 1-2.
4. Remove the hex flange nut that secures the blade to the
spindle.
IMPORTANT:
The hex flange nuts have a right-handed
(normal) thread pattern. Do NOT attempt to force the nuts in the
opposite direction. Doing so may damage the nuts.
5. Repeat steps 2 and 3 on the other cutting blades.
6. Replace the blades with the blades included in the kit. Be
sure to install each blade with the side marked ''Bottom''
(or with a part number stamped in it) facing the ground
when the mower is in the operating position.
IMPORTANT:
Use a torque wrench to tighten each blade
spindle's hex flange nut to between 80 ft-lb and 100 ft-lb.
