To install the cutting blade (Fig. 29)
NOTICE: To re-install or replace the blade, make sure that all parts
are replaced in the exact order in which they are removed
(Fig. 28b).
1. If the flange is removed during blade removal, align it with the
motor shaft first and then assemble it into place.
2. While wearing protective gloves, position the blade on the
flange with the surface stating "THIS SIDE FACING GRASS"
facing toward outside (Fig. 29a).
3. Align the washer with the motor shaft and mount it onto the
motor shaft.
4. Mount the bolt into the motor shaft. Hand tighten the bolt
clockwise.
5. Move the blade by hand to align the two holes in the blade
with the two holes in the flange (Fig. 29a).
6. Place a screwdriver or metal rod 1/4 in (6.35 mm) or a little
less in diameter (e.g., a bit) into the aligned hole in the blade
and the flange to act as a stabilizer. Place another screwdriver
or metal rod 5/16 in (8 mm) or a little less in diameter into the
fixing hole in the motor to act as a stabilizer (Fig. 29b).
7. Use a 9/16 in (14 mm) torque wrench to tighten the bolt
clockwise. The recommended torque for the blade bolt is
36-41 ft-lb (50-55 Nm).
8. Repeat the steps with the second blade, if needed.
9. Reassemble the deck onto the tractor as directed in
"REMOVING THE DECK" in this manual.
WARNING: Ensure that the blade is properly seated and the
blade bolt is tightened to the torque specifications above. Failure to properly attach the blade could cause it to come loose
and result in possible serious personal injury.
SHARPENING THE CUTTING BLADE (Fig. 30)
WARNING: Always protect your hands by wearing heavy gloves or wrapping the cutting edges with rags or other
materials when performing any maintenance on the blade(s). Always remove the safety key and battery packs when
servicing or transporting the tractor.
WARNING: Always wear eye protection with side shields marked to comply with ANSI Z87.1. Failure to do so could
result in objects being thrown into your eyes resulting in possible serious injury.
WARNING: A worn, cracked, or damaged blade can break, and pieces of the damaged blade can become dangerous
projectiles. Thrown objects can cause serious injury. Inspect the blade regularly, and do not operate the tractor with a
worn or damaged blade.
