Mower Maintenance
Servicing the Cutting Blades
Maintain sharp blades throughout the cutting season
because sharp blades cut cleanly without tearing or
shredding the grass blades. Tearing and shredding
turns grass brown at the edges, which slows growth
and increases the chance of disease.
Check the cutter blades daily for sharpness, and for
any wear or damage. File down any nicks and sharpen
the blades as necessary. If a blade is damaged or
worn, replace it immediately with a genuine Exmark
replacement blade. For convenient sharpening and
replacement, you may want to keep extra blades on
hand.
WARNING
A worn or damaged blade can break, and a piece
of the blade could be thrown into the operator's
or bystander's area, resulting in serious personal
injury or death.
•
Inspect the blade periodically for wear or
damage.
•
Replace a worn or damaged blade.
Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the
blade control switch, and ensure the parking brake is
engaged. Stop the engine and remove the key.
Inspecting the Blades
Service Interval: Before each use or
daily—Check the cutting
blades.
1. Inspect the cutting edges (Figure 58). If the edges
are not sharp or have nicks, remove and sharpen
the blades; refer to Sharpening the Blades.
2. Inspect the blades, especially the curved area
(Figure 58). If you notice any damage, wear,
or a slot forming in this area (items 3 and 4 in
Figure 58), immediately install a new blade.

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 measured into a position that allows effective
measurement of the distance between the cutting
edge and the level surface the machine is on.
