CUTTER DECK ADJUSTMENTS

Due to the many cutting conditions that exist, it is
difficult to suggest a cutter deck setting that will
work for every lawn. There are two adjustments that
can be made on these decks, pitch and height.
PITCH is the angle of the blades (comparing front to
rear). A 1/4" downward pitch (front of deck down) is
BELT
recommended for best cutting performance.
HEIGHT is the nominal distance the blade is off of the
ground. This measurement is made with the blades
pointed side to side and distance is measured between
cutting tip and ground. (Also see Blade Height Adjust-
ment)
Changes to the cutting height can be achieved by
SC400G
repositioning the cutter deck. (This adjustment will also
effect the pitch of the deck). There are three available
positions (see figure 4).
Deck
Caster spacers also can be repositioned to change
cutting heights and to change the pitch of the deck.
