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.
3. 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. See Figure 6-5

Due to 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 to the cutter
deck, 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 the 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 6-7.
Caster spacers also can be repositioned to change the
cutting heights and to change the pitch of the cutter deck.
See Figure 6-8.
