TRANSMISSION DRIVE BELT

Adjust the transmission drive belt so that there is about a
3/16" deflection with 10 lbs. of pressure. Adjust by
loosening idler pulley mounting bolt and sliding the idler
left or right to change belt tension.

DRIVE CONTROL ADJUSTMENTS

1. Adjust the steering control rods so that there is
approximately 3/4" clearance from the bottom of
the rod to the bottom of the neutral latch slot when
in the drive position. (See Figure 4)

2. Adjust the steering brake rods so that the brakes
do not apply until the steering levers are pulled tight
to the handles. When the steering levers are
locked in the neutral position the machine should
move freely.

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 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-
