TROUBLESHOOTING GUIDE
PROBLEM POSSIBLE CAUSE POSSIBLE REMEDY
Leaves a
streak of uncut
or partially cut
grass
1. Mower not level side to side. Level 3 Point Hitch linkage on tractor.
2. Blades dull or bent. Sharpen or replace blades.
3. Carrier RPM too low. Use correct PTO speed.
4. Field conditions are so wet that the
tractor tire is pushing grass into
mud.
Too wet to mow. Stop operation and wait
until it is drier.
5. Ground speed too fast.
Reduce ground speed by shifting to a lower
gear.
6. Blades lock back. Free blades.
7. Blades riding up due to blade bolt
wear or loose bolts.
Replace blade bolts.
8. Grass is down from previous weather
conditions.
Mow in only one direction.
9. Possible build up of material under
mower.
Clean mower.
10. Weed and grass stems are pushed
down by tractor tires and do not
rebound up so they can be cut (this
can happen when weed/grass is
high).
Mow again in opposite direction.
Mow back and forth with enough overlap to
mow tire track of previous cut again.
Offset mower to left 4"-6” by adjusting
stabilizer bars. Then mow in counter
clockwise direction (rotation direction of
blades will help cut stems pushed forward).
Grass cut
lower in center
of swath than
at edge
Height of mower lower at rear or front.
Adjust mower height and attitude so that
mower rear and front are within ½” of same
height. See tailwheel adjustment instructions.
Material
discharges
from mower
unevenly;
bunches of
material along
swath.
1. Material too high and too much
material.
Reduce ground speed but maintain 540 rpm
at tractor PTO, or make two passes over
material. Raise mower for the first pass and
lower to desired height for the second and
cut a 90° to first pass. Raise rear of mower
high enough to permit material to discharge,
but not so high that conditions listed above
occur.
2. Grass Wet.
Allow grass to dry before mowing. Slow
ground speed of tractor but keep engine
running at full PTO rpm. Cutting lower will
help.
3. Rear of cutter too low, trapping
material under mower.
Adjust mower height and attitude. (see
instructions).
Gearbox
overheating
1. Low on lubricant. Fill to proper level.
2. Improper type lubricant. Replace with proper lubricant.
3. Excessive trash build-up around
gearbox.
Remove trash.
