Troubleshooting

Problem
There are areas of uncut grass at the
overlap between cutting cylinders.
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 one cylinder.
There is a step in the cut grass height
at the point of overlap between cutting
cylinders.
There are some uncut or poorly cut
strands of grass.
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 one end
of the cutter because of poorly routed
hoses or wrongly positioned hydraulic
adaptors.
4. There is no ground contact on one
end of the cutter because a pivot pin
is seizing.
5. There is no ground contact on one end
of the cutter because of grass buildup
under the cutterhead.
1. The forward speed is too high.
2. The cylinder speed is too slow.
3. The height of cut is too low.
1. A cylinder is running slow.
1. There is an inconsistent height of cut
setting on one cylinder.
2. The raise/lower position control is not
in the float position.
3. There is no ground contact on one end
of the cutter because of poorly routed
hoses or wrongly positioned hydraulic
adaptors.
4. There is no ground contact on one
end of the cutter because of pivot pins
seizing.
5. There is no ground contact on one end
of the cutter because of grass buildup
under the cutterhead
1. A cutting cylinder is partially out of
contact with the bottom blade.
2. A cutting cylinder is in heavy contact
with the bottom blade.
3. The height of cut is too high.
4. The cutting edges of the cutting
cylinders/bottom blades are rounded.

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 cylinder 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 adaptors.
4. Release and grease the pivot points.
5. Remove the grass buildup.
1. Adjust the
cutting-cylinder-to-bottom-blade
contact.
2. Adjust the
cutting-cylinder-to-bottom-blade
contact.
3. Lower the height of cut setting.
4. Back lap or grind the edges.
