belt adjustment.
CUTTER DECk ADJUSTMENTS 6.6
WARNING
DO NOT adjust the cutting height with the mower
blades rotating. Disengage the power to the cutter
blades and then adjust cutting height.
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 or to the bottom of the spindle shaft. All
blades should be positioned equally The unit is shipped
with one spacer on top of spindle and four underneath.
See Figure 6-7.
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; i.e. 4 or 5 spacers below the
spindle shaft.
