Troubleshooting
Mowing Conditions
PROBLEM
Grass cut lower in center of swath than at edge
Streaking conditions in swath
Material discharges from cutter unevenly;
bunches of material along swath
Cutter will not cut (Shear bolt drive only)
Cutter will not cut all the time
(Slip clutch drive only)
POSSIBLE CAUSE
Height of cutter lower at rear or front
Conditions too wet for mowing
Blades unable to cut that part of grass
pressed by path of tractor tires
Dull blades
Material too high and too much material
Grass wet
Rear of cutter too low, trapping material
under cutter
Shear bolt sheared
Slip clutch slipping
TROUBLESHOOTING
SOLUTION
Adjust cutter height and attitude so that cutter
rear and front are within 1/2" of same height.
Allow grass to dry before mowing.
Slow ground speed of tractor but
Sharpen or replace blades.
Reduce ground speed but maintain 540 RPM
at tractor PTO or make two passes over
material. Raise cutter for the first pass and
lower to desired height for the second and
cut at 90° to first pass. Raise rear of cutter
high enough to permit material to discharge
but not so high as to cause conditions listed
above.
Allow grass to dry before mowing. Slow
ground speed of tractor but keep engine
running at full PTO RPM. Cutting lower will
help.
Adjust cutter height and attitude.
Install new shear bolt.
Adjust slip clutch according to instructions in
Slip Clutch Adjustment, page 21.
