Maintenance
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; also considered the 'transport' position.
2.
While wearing thickly padded gloves or other
adequate hand protection slowly rotate blade to
be measure into a position that allows effective
measurement of the distance between the cutting
edge and the level surface the machine is on.

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

5.
Measure from the tip of the blade to the flat
surface here. The variance should be no more
than 1/8 inch (3mm).

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