Troubleshooting

Problem
There are areas of uncut grass at the
overlap between cutting units.
There are full-width ridge lines in the cut
across the direction of travel.
There are ridge lines in the cut grass,
across the direction of travel, over the
cutting width of 1 cutting unit.
There is a step in the cut grass height at
the point of overlap between cutting units.
There are some uncut or poorly cut
strands of grass.
There are lines of uncut or badly cut grass
in the direction of travel.
There is scalping of the turf.
Possible Cause
1. You are turning too tightly.
2. The machine slides sideways when
driving the machine across the face of
a slope.
3. There is no ground contact on 1 end
of the cutting unit because of poorly
routed hoses or wrongly positioned
hydraulic adapters.
4. There is no ground contact on 1 end
of the cutting unit because a pivot pin
is seizing.
5. There is no ground contact on 1 end
of the cutting unit because of grass
buildup under the cutting unit.
1. The forward speed is too high.
2. The rotor speed is too slow.
3. The height of cut is too low.
1. A rotor is running slow.
1. There is an inconsistent height-of-cut
setting on 1 cutting unit.
2. The raise/lower position control is not
in the float position.
3. There is no ground contact on 1 end
of the cutting unit because of poorly
routed hoses or wrongly positioned
hydraulic adapters.
4. There is no ground contact on 1 end of
the cutting unit because of pivot pins
seizing.
5. There is no ground contact on 1 end
of the cutting unit because of grass
buildup under the cutting unit
1. A blade is stuck.
2. A blade is damaged.
3. The height of cut is too high.
4. The cutting edges of the blades are
rounded.
1. The blades are in contact with the
ground.
2. The cutting unit has a nose-down
angle.
3. The cutting units are bouncing.
4. There are worn rotor bearings/bearing
housing pivots.
5. There are loose components in the
cutting unit.
1. The undulations are too severe for the
height of cut setting.
2. The height of cut is too low.

Corrective Action
1. Increase the turning radius.
2. Mow up/down the slope.
3. Correct the hose routing or the position
of the hydraulic adapters.
4. Release and grease the pivot points.
5. Clear the grass buildup.
1. Reduce forward speed.
2. Increase engine speed.
3. Raise the height of cut.
1. Check the rotor speed; consult your
authorized distributor.
1. Check and adjust the height-of-cut
setting.
2. Set the position control to the float
position.
3. Correct the hose routing and the
position of the hydraulic adapters.
4. Release and grease the pivot points.
5. Remove the grass buildup.
1. Free the blade.
2. Replace the blade.
3. Lower the height of cut.
4. Replace or sharpen the blades.
1. Raise the height of cut.
2. Adjust the cutting unit to position the
cutting unit parallel to the ground.
3. Reduce the forward speed and reduce
the weight transfer.
4. Replace any worn parts.
5. Check and tighten components as
necessary.
1. Raise the height of cut.
2. Raise the height of cut.
