Cutter Deck 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 Hayter replacement
blade. For convenient sharpening and replacement, you
may want to keep extra blades on hand.

2. Rotate the blades until the ends face forward and
backward (Figure 46). Measure from a level surface
to the cutting edge, position A, of the blades

3. Rotate the opposite ends of the blades forward.
4. Measure from a level surface to the cutting edge of
the blades at the same position as in step 2. The
difference between the dimensions obtained in steps
2 and 3 must not exceed 1/8 inch (3 mm). If this
dimension exceeds 1/8 inch (3 mm), the blade is
bent and must be replaced. Refer to Removing the
Blades and Installing the Blades.

Note: If a bent blade is replaced with a new one and
the dimension obtained continue to exceed 1/8 inch
(3mm), the blade spindle could be bent. Contact an
