Sharpening the Blades

the blade
(Figure

Note: Maintain the original angle.
Note: The blade retains balance if you remove the
same amount of material from both cutting edges.
Figure 93
1. Sharpen at the original angle
2. Check the balance of the blade by putting it on a blade
balancer
(Figure

Note: If the blade stays in a horizontal position, the
blade is balanced and ready to use.

Installing the Blades
Important: The right blade on this mower deck is
counter-rotating and uses a left-threaded blade bolt. Use
Figure 96
for the correct placement of the mower blades.
1. Install the left and center blades, curved washers, and
blade bolts to the spindle shafts
96).
Important: The curved part of the blade must
point upward toward the inside of the mower to
ensure proper cutting.
Note: Install the curved-washer cone towards the bolt
head
(Figure
95).
2. Install the right blade, curved washer, and blade bolt
(left-threaded bolt) to the spindle shaft
