Due to initial belt stretch and to prevent the belt
from slipping, check this adjustment after the
first 2 hours, 4 hours and 8 hours of operation.

Adjust the RH blade drive belt using a belt
tension gauge. Adjust the belt so that the belt
moves 1/2" with 10 pounds of pressure. Adjust
the tension by tightening or loosening the J-bolt nut
(See figure 3).

Adjusting the blade height can be done by moving
any number of the five smaller 1/4" spacers on the
blade mounting bolts to the top of the spindle shaft
or below the spindle shaft.
-NOTE-
All blades should be positioned equally.
For best cut and discharge, a minimum of three
spacers should be installed between the blade and the
spindle (See figure 6).

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 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 Adjustment)
Changes to the cutting height can be achieved by
repositioning the cutter deck. (This adjustment will
also effect the pitch of the deck). There are three
available positions (see figure 4).
