Troubleshooting
Problem
Possible Cause
Corrective Action
1. You are turning too tightly.
1. Increase the turning radius
2. The machine slides sideways when
travelling across the face of a slope.
2. Mow up/down the slope.
3. There is no ground contact on an end
of the cutting unit because of poorly
routed hoses or incorrectly positioned
hydraulic adaptors.
3. Correct the hose routing or the position
of the hydraulic adaptors.
4. There is no ground contact on an end
of the cutting unit because a pivot pin
is seizing.
4. Release and grease the pivot points.
There are areas of uncut grass at the
overlap between flail rotors.
5. There is no ground contact on an end
of the cutting unit because of grass
buildup under the cutting unit.
5. Clear the grass buildup.
1. The forward speed is too high.
1. Reduce forward speed.
2. The flail rotor speed is too slow.
2. Increase the mower engine speed.
There are full-width ridge lines in the cut
across the direction of travel.
3. The height of cut is too low.
3. Raise the height of cut.
There are ridge lines in the cut grass,
across the direction of travel, over the
cutting width of a flail rotor.
1. A flail rotor is running slow.
1. Check the flail rotor speed; contact
your distributor.
1. There is an inconsistent height-of-cut
setting on a flail rotor.
1. Check and adjust the height-of-cut
setting.
2. The raise/lower position control is not
in the float position.
2. Set the position control to 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.
3. Correct the hose routing and the
position of the hydraulic adaptors.
4. There is no ground contact on an end
of the cutting unit because of pivot pins
seizing.
4. Release and grease the pivot points.
There is a step in the cut grass height at
the point of overlap between flail rotors.
5. There is no ground contact on an end
of the cutting unit because of grass
buildup under the cutting unit.
5. Remove the grass buildup.
1. The height of cut is too high.
1. Lower the height-of-cut setting.
There are some uncut or poorly cut
strands of grass.
2. The cutting edges of the flails are
rounded.
2. Sharpen the blades.
1. The cutting units are bouncing.
1. Reduce the forward speed and reduce
the weight transfer.
2. There are worn flail bearings/bearing
housing pivots.
2. Replace any worn parts.
3. There are loose components in the
cutting unit.
3. Check and tighten components as
necessary.
There are lines of uncut or badly cut grass
in the direction of travel.
4. Flail blades are not pivoting freely.
4. Ensure that all flail blades are able to
pivot freely.
There is scalping of the turf.
1. The undulations are too severe for the
height-of-cut setting.
1. Raise the height of cut.
