tractor on a firm and level surface, set the parking
brake, place the PTO in the disengaged (OFF)

Place a block of wood between the deck housing baffle 3.

blade to its spindle assembly. See Fig. 1-2.

thread pattern. Do NOT attempt to force the nuts in the opposite
direction. Doing so may damage the nut.
Replace the blades with the blades included in the kit. Be 4.
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.

spindles hex flange nut to between 70 ft-lb and 90 ft-lb.
