TROUBLE SHOOTING
MOWING CONDITIONS
BELT CONDITIONS
* Check belt for damage by laying it flat on the floor. A belt that does not lie flat (has humps or twists, indicating broken or stretched cords) must be replaced.
PROBLEM POSSIBLE CAUSE SOLUTION
Grass cut higher in center of swath than at
edge Height of mower higher at rear than at front Adjust mower height and attitude so that mower rear
and front are within 12 mm of same height. See
instructions on page 9.
Grass cut lower in center of swath than at

and front are within 12 mm of same height. See
instructions on page 9.
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.
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.
Rear of mower too low, trapping material under
mower Adjust mower height and attitude.
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
belt.
Belt hung up or rubbing Check belt position in pulleys and idlers. Check belt
for free travel in pulleys. Check under mower and
around blade spindle shaft for wire, rags, or other
foreign material. Clean all material from under mower.
Frayed edges on belt cover Belt misaligned or belt rubbing guide Re-align belt. Be sure belt does not rub any other part
while running.
Pulley misaligned Inspect to ensure belt is running in center of backside
idler. Shim idler as necessary to align.
Damaged belt Rollover, high shock loads or installation
damaged Replace belt.*
Belt breakage High shock loads Avoid abusive mowing. Avoid hitting the ground or
large obstructions.
Belt came off drive Check pulleys for foreign material in grooves. Avoid
hitting solid objects or ground.
