Checking for Bent Blades
Note: The machine must be on a level surface for
the following procedure.
1. Raise the mower deck to the highest
height-of-cut position.
2. While wearing thickly padded gloves, or other
adequate hand protection, slowly rotate the
blade into a position that allows you to measure
the distance between the cutting edge and the
level surface the machine is on ( Figure 77 ).

3. Measure from the tip of the blade to the at
surface ( Figure 78 ).

4. Rotate the same blade 180 degrees so that
the opposing cutting edge is now in the same
position ( Figure 79 ).

position
5. Measure from the tip of the blade to the at
surface ( Figure 80 ).
Note: The variance should be no more than
3 mm (1/8 inch).

A. If the dif ference between A and B is greater
than 3 mm (1/8 inch), replace the blade with
a new blade; refer to Removing the Blades
( page 63 ) and Installing the Blades ( page
63 ) .
Note: If a bent blade is replaced with a
new blade, and the dimension obtained
continues to exceed 3 mm (1/8 inch), the
blade spindle could be bent. Contact an
Authorized Service Dealer for service.
B. If the variance is within constraints, move to
the next blade.
6. Repeat this procedure on each blade.
