ADJUSTMENTS
CUTTER DECK ADJUSTMENTS
TAPERED BEARING SPINDLE ASSEMBLY
Due to the many conditions that exist, it isdifficultto suggest
a 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
positive pitch
is when the front (leading) edge of the cutting
plane is lowerthan the rear (trailing) edge,
level pitch
is when
both front and rear are the same height, a
negative pitch
is
when the leading edge is higher than the rear edge. We
suggest that a postive pitch be used when cutting grass. The
front of the deck should be 1/4" to 1/2" lower than the rear
of the deck.
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.
BALL BEARING SPINDLE ASSEMBLY
Adjusting the blade height can be done by moving any
number of the four smaller 1/4" spacers on the blade
mounting bolts to the top of the spindle shaft or below the
spindle shaft. (All blades should be positioned equally). The
tapered bearing spindle has a large 1/4" spacer that is
installed directly below the spindle housing and is secured
to the spindle with two roll pins. The blade can be adjusted
all the way up to the spindle assembly if all the smaller 1/4"
spacers are removed and installed above the pulley. The
larger 1/4" spacer can then be removed along with the roll
pins. (Do not install the larger 1/4" spacer above the pulley,
store it in a convienant location away from the machine).
When any 1/4" spacers are installed above the blades the
larger 1/4" spacer must be installed directly below the
spindle housing. If a smaller 1/4" spacer is installed directly
below the spindle housing and contacts the retaining ring
this will cause a spindle failure and not be warrantable. For
best cut and discharge a minimum of three spacers should
be between the blade and spindle. (SEE FIGURE 10)
Adjusting the blade height can be done by moving any
number of the five spacers on the blade mounting bolts to
the top of the spindle shaft or below the spindle shaft (all
blades should be positioned equally). Unit is shipped with
one spacer on top and four underneath (see figure 9). For
best cut and discharge a minimum of three spacer should be
between the blade and spindle.
