Maintenance
Checking the Tire Pressure
Maintain the air pressure in the front and rear
tires as specified. Uneven tire pressure can
cause uneven cut. Check the pressure at the
valve stem after every 25 operating hours or
monthly, whichever occurs first (
Figure 35
).
Check the tires when they are cold to get the
most accurate pressure reading.
Rear Tires: 13 psi (90 kPa)
Front Tires (caster wheels): 13 psi (90 kPa)

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.
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 move
the motion control levers outward to the
neutral position and engage parking brake.
Stop the engine, remove the key, and
disconnect the spark plug wire(s) from the
spark plug(s).
Inspecting the Blades
1. Inspect the cutting edges (
Figure 36
). 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 36
). If you notice any
damage, wear, or a slot forming in this
area (item 3 in
Figure 36
), immediately
install a new blade.
