Loose blade
Check blade hardware
Streaking conditions in swath
Conditions too wet for mowing
Allow grass to dry before mowing.
Blades unable to cut that part of grass pressed
down by path of tractor tires
Slow ground speed of tractor but keep engine running
at full PTO rpm. Cutting lower will help. Adjust tractor
tire spacing if possible.
Dull blades
Sharpen or replace blades.
Loose blade
Check blade hardware.
Material discharges from mower unevenly;
bunches of material along swath
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 for the second and cut at
90 degrees to first pass. Raise rear of mower high
enough to permit material to discharge, but not so high
that conditions listed above occur.
Grass wet
Allow grass to dry before mowing. Slow ground speed
of tractor but keep engine running at full PTO rpm.
PROBLEM
POSSIBLE CAUSE
SOLUTION
Belt slippage
Mower overloading; Material too tall or heavy
Reduce tractor ground speed but maintain full PTO
rpm. Cut material twice, one high pass and then mow
at desired height. Cut at 90 degrees to first pass.
Oil on belt from over lubrication
Be careful not to over lubricate. Clean lubricant from
belt and pulleys with clean rag. Replace oil-soaked
