Mower Level (Side to Side)
WARNING: Stop engine, remove key,
wait for moving par ts to stop and
remove wire from spark plug before
attempting the following adjustment
procedures.
CAUTION:
Use sturdy gloves or
padding to protect hands when working
with mower blade(s).
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.)
•
With tractor positioned on a smooth, flat, level
surface and tire pressure properly set, perform
the following procedures in order of appearance.
Refer to figure 20 and 21.
•
With blade(s) positioned side to side, measure
distance of blade(s) tips to floor at right and left
side of mower pan. Rotate blade(s) 180 degrees
and check again. The measurement should be
equal within 1/8 of an inch side to side.
•
To correct for difference in height of blade tips
from side to side, loosen nut on height adjuster.
Turn height adjuster clockwise on low side of
mower pan to raise low side one half the
difference in height. Turn height adjuster
counterclockwise on high side to lower high side
the other one half of the height difference.
Mower Pitch and Height
•
Proper blade pitch is when blade tip (measured
from surface is 1/8” to 1/4” lower at front of
mower pan than when same tip is at rear of
mower pan. To adjust pitch loosen flangelock
nuts and slide adjusting tabs up or down to
achieve proper pitch (Figure 20 & 22).
•
Adjusting height adjuster hooks equally raises or
lowers mower pan and changes cutting height.
To adjust, loosen upper nuts on hanger hooks
and turn lower nuts equally clockwise to lower or
counterclockwise to raise rear of rotary mower.
With mower attachment lift in highest position
front blade height should measure 4” from ground
level.
•
Secure hanger hooks in position by securely
tightening nuts.
