Sharpening the Blade(s)
1.
Use a file to sharpen the cutting edge at both
ends of the blade (Fig. 34). Maintain the original
angle. The blade retains its balance if the same
amount of material is removed from both cutting
edges.

2.
Check the balance of the blade by putting it on a
blade balancer (Fig. 35). If the blade stays in a
horizontal position, the blade is balanced and can
be used. If the blade is not balanced, file some
metal off the back side of the blade. Repeat this
procedure until the blade is balanced.

Installing the Blade(s)
1.
Install the blade, blade retainer, curved washer
(cupped side toward blade), and the blade bolt
(Fig. 33).
IMPORTANT: The curved part of the blade
must be pointing toward the inside of the
mower to assure proper cutting.
2.
Tighten the blade bolt to 45–60 ft-lb
(61–81 Nm).
Removing the Mower
1.
Park the machine on a level surface, disengage
the blade control (PTO), shift into neutral, set
the parking brake, and turn the ignition key to
“OFF” to stop the engine.
2.
Remove the key from the ignition switch and
pull the wire off the spark plug.
3.
Move the height-of-cut lever (deck lift) into the
“D” notch.
4.
Remove the height-of-cut lift assist spring from
the retaining bolt (Fig. 36), using the spring tool
provided with the machine. The spring is
between the frame and the right rear wheel.
