CUTTER DECK ADJUSTMENTS
Due to the many conditions that exist, it is difficult
to suggest a setting that will work for every lawn.
There are, however, two adjustments that should be
made on the cutter deck: pitch and height.
PITCH
is the angle of the blades (comparing front
to rear).
HEIGHT
is the nominal distance that the blade is
off the ground. This measurement is made with the
blades pointed side to side and distance is measured
between cutting tip and ground.
Adjusting the blade height can be done by moving
any number of the five smaller spacers on the blade
mounting bolts to the top of the spindle shaft or to
the bottom of the spindle shaft. All blades should be
positioned equally (See Figure10).
The unit is shipped with one spacer on top of spindle
and four underneath (See Figure 10).
This adjustment does not affect blade pitch.
-NOTE-
For best results, keep the cutter deck
high in relation to the engine deck and
the blades low in the cutter deck; ie. 4 or
5 spacers below the spindle shaft.
Additional range to the cutting height can be
achieved by repositioning the cutter deck in relation-
ship to the engine deck. This adjustment also affects
the pitch of the deck.
There are three positions for mounting the cutter
deck (See Figure 11). For cutting in the lowest
position, mount the cutter deck in the top hole (A).
For cutting in the highest position, mount the deck in
the lowest hole (C). Setting the cutter deck height
will be determined by the type of cutting conditions.
Caster spacers also can be repositioned to change
the cutting heights and to change the pitch of the
deck (See Figure 12).
To adjust the caster spacers, raise the deck and
remove the pin and caster wheel. Reposition the
caster spacers as needed, then replace the caster, top
spacers and pin. Make the same adjustments on the
other caster wheel.
To adjust the blade height, move any number of the
five 1/4" thick spacers on the blade mounting bolts
to the top of the spindle shaft or below the spindle
shaft.
