4.7 MOWER PAN
Mower Level (Side to Side)
NOTE: A wood block (about 1" square by 5" long) may
be used under pan for blade measurement. Wrap block
with masking tape, mark tape with cutting edge of
blade and measure distance from end of block to
mark(s). This method avoids errors by having to read
any measurements under pan.
To level mower pan, turn adjustment cap screw on
adjustment lever clockwise to raise right side or
counterclockwise to lower it (Figure 8).
Cutting Height
Cutting height range is 1" to 4" (2.5 to 10.1 cm). Place
unit on a smooth, flat, level surface.
1. With blade (s) positioned side to side, measure
distance of blade(s) tips to floor at right and left
side of mower pan (Figures 8 and 9).
2. Rotate blade(s) 180
o
and check again. The
measurement should be equal within 1/8" (3.2 mm)
side to side.
To correct for difference in height of blade tips from
side to side:
1. Loosen nuts on adjustment levers.
2. Turn lever adjustment screw clockwise on the low
side of mower pan to raise the low side to one half
the difference in height.
3. Turn lever adjustment screw counterclockwise on
the high side to lower high side the remaining one
half of the height difference.
4. Tighten nuts on adjustment levers.
