When to Sharpen
Cutting units should be kept as sharp as possible to:
S Promote growth of healthy grass.
S Optimize cutting unit performance.
S Extend the life of the mower.
S Maximize operator mowing time.
S Allow the tractor to run most efficiently.
S Provide excellent finished appearance of the turf.

S The cutting unit is noisy.
S “Its that time of year”.
One sure way to determine the answer to this is by actu-
ally checking the cutting edges of the reel and bedknife
to see if they are dull, nicked, bent or being run without
light contact against one another.
A grooved or wavy (rifled) reel or bedknife is most often
caused by operating the cutting unit with heavy bedknife
to reel contact. This condition can only be corrected by
grinding the reel and bedknife – BACKLAPPING WILL
NOT CORRECT THIS CONDITION.
Streaks will appear on the low areas of a
grooved or wavy (rifled) bedknife
Reel blades, and the edge of the bedknife, should be
checked for damage visually and by carefully feeling the
edges. Of course, this should only be done when it is
certain that the reel cannot be started,. and never slide
your fingers down the edges lengthwise.
Rounded edges on the reel blades and bedknife will
cause the grass blades to be pinched and torn, rather
than sheared off cleanly. When light contact is not main-
tained, dull edges will soon result.
