Remove the blades from your tractor’s cutting deck as 
follows.

•

Remove the cutting deck from beneath the tractor, 
(refer to Deck Removal in the Maintenance section of 
your tractor’s operator’s manual for detailed 
instructions) then gently flip the deck over to 
expose its underside.

•

Place a block of wood between the center deck 
housing baffle and the cutting blade to act as a 
stabilizer. See Figure 10.

•

Use a 15/16" wrench to remove the hex flange nut 
that secures the blade to the spindle assembly. See 
Figure 10.

NOTE:  The hex flange nut has a right-handed thread
pattern. Do NOT attempt to force the nut in the incorrect
direction. Doing so may damage the nut and create a
safety hazard.

Attach the new blades from the bagger kit as follows:

•

Install the new blades packed with the bagger. 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.

•

Mount the smaller of the three blades to the center 
spindle. The remaining two blades are 
interchangeable.

 Use a torque wrench to tighten the blade 

spindle hex flange nut to between 70 foot-pounds and 
90 foot-pounds.

•

Re-mount the cutting deck. 

•

Open the grass bag cover by lifting the cover up  as 
shown in Figure 11A. Do not remove the chute tube 
assembly from the tractor.

•

Remove the grass bags by lifting these up and 
moving the  bags away from the support tube 
assembly. See Figure 11B.

•

To empty the grass clippings at a proper disposal 
sight, use the handle at the bottom of each grass 
bag. Holding the bag firmly as shown below in
