Troubleshooting
Problem
There are areas of uncut grass at the
overlap between flail rotors.
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 a flail rotor.
There is a step in the cut grass height at
the point of overlap between flail rotors.
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
travelling across the face of a slope.
3. There is no ground contact on an end
of the cutting unit because of poorly
routed hoses or incorrectly positioned
hydraulic adaptors.
4. There is no ground contact on an end
of the cutting unit because a pivot pin
is seizing.
5. There is no ground contact on an end
of the cutting unit because of grass
buildup under the cutting unit.
1. The forward speed is too high.
2. The flail rotor speed is too slow.
3. The height of cut is too low.
1. A flail rotor is running slow.
1. There is an inconsistent height-of-cut
setting on a flail rotor.
2. The raise/lower position control is not
in the float position.
3. There is no ground contact on an end
of the cutting unit because of poorly
routed hoses or incorrectly positioned
hydraulic adaptors.
4. There is no ground contact on an end
of the cutting unit because of pivot pins
seizing.
5. There is no ground contact on an end
of the cutting unit because of grass
buildup under the cutting unit.
1. The height of cut is too high.
2. The cutting edges of the flails are
rounded.
1. The cutting units are bouncing.
2. There are worn flail bearings/bearing
housing pivots.
3. There are loose components in the
cutting unit.
4. Flail blades are not pivoting freely.
1. The undulations are too severe for the
height-of-cut setting.

Corrective Action
1. Increase the turning radius
2. Mow up/down the slope.
3. Correct the hose routing or the position
of the hydraulic adaptors.
4. Release and grease the pivot points.
5. Clear the grass buildup.
1. Reduce forward speed.
2. Increase the mower engine speed.
3. Raise the height of cut.
1. Check the flail rotor speed; contact
your 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 adaptors.
4. Release and grease the pivot points.
5. Remove the grass buildup.
1. Lower the height-of-cut setting.
2. Sharpen the blades.
1. Reduce the forward speed and reduce
the weight transfer.
2. Replace any worn parts.
3. Check and tighten components as
necessary.
4. Ensure that all flail blades are able to
pivot freely.
1. Raise the height of cut.
