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).
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, next page).
Changes to the cutting height can be achieved by reposi-
tioning the cutter deck. (This adjustment will also effect
the pitch of the deck). There are three available posi-
tions (see Figure 4).
