Attaching The Blades
NOTE: If your tractor is equipped with a 46" cutting deck,
three 2-in-1 cutting blades are included with this kit. For
improved bagging performance, install these blades on
your tractor using the following instructions.
Remove the blades from your tractor's cutting deck as
follows:
1. Remove the cutting deck from beneath the tractor,
(refer to Deck Removal in the MAINTENANCE
Larger Blades
Part No. 742-0644 section of your tractor's operator's manual for detailed
instructions) then gently flip the deck over to expose
its underside.
2. Place a block of wood between the center deck hous-
ing baffle and the cutting blade to act as a stabilizer,
keeping the blades from turning when you loosen the
hex flange nuts.
3. Use a 15/16" wrench to remove the hex flange nut that
secures the blade to the spindle assembly.
NOTE: The hex flange nut has a normal (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.
4. 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 rider is in the operating
position.
5. Mount the SMALLER of the three blades to the
CENTER spindle. The remaining two blades are
interchangeable. See Fig. 5-1.
6. Use a torque wrench to tighten the blade spindle hex
flange nut to between 70 and 90 foot-pounds.
7. Remount the cutting deck.
