Troubleshooting
Problem
Possible Cause
Corrective Action
1. Turning too tightly
1. Reduce turning radius
2. Mower sliding sideways when travelling
across face of slope
2. Mow up/down slope
3. No ground contact on one end of the
cutter because poorly routed hoses or
wrongly positioned hydraulic adaptors
3. Correct hose routing/reposition
hydraulic adaptors
4. No ground contact on one end of the
cutter because pivot pins seizing
4. Release and grease pivot points
Areas of uncut grass at overlap between
cutting cylinders
5. No ground contact on one end of the
cutter because of grass build up under
cutterhead
5. Remove grass
1. Forward speed too high
1. Reduce forward speed
2. Cylinder speed too slow
2. Increase mower engine speed
Ridge lines in the cut across the direction
of travel over full width
3. Height of cut too low
3. Raise height of cut
Ridge lines in the cut grass across the
direction of travel over cutting width of one
cylinder
1. Cylinder is running slow
1. Refer to TROUBLE SHOOTING
1. Inconsistent height of cut setting on
one cylinder
1. Check and readjust height of cut setting
2. Raise/lower position control not in float
position
2. Operate position control to float position
3. No ground contact on one end of the
cutter because poorly routed hoses or
wrongly positioned hydraulic adaptors
3. Correct hose routing/reposition
hydraulic adaptors
4. No ground contact on one end of the
cutter because pivot pins seizing
4. Release and grease pivot points
Step in cut grass height at point of overlap
between cutting cylinders
5. No ground contact on one end of the
cutter because of grass build up under
cutterhead
5. Remove grass
1. Cutting cylinder is partially out of
contact with the bottom blade
1. Readjust cutting cylinder to bottom
blade
2. Cutting cylinder is in heavy contact with
the bottom blade
2. Readjust cutting cylinder to the bottom
blade
3. Height of cut is too high
3. Lower height of cut setting
Some uncut or poorly cut strands of grass
4. Cutting edges of cutting
cylinders/bottom blades are rounded
4. Back lap or regrind to restore cutting
edges
1. Tram lining of cutting edges due to
heavy contact caused by poor cutting
cylinder to bottom blade adjustment
1. Back lap or regrind to restore cutting
edges
2. Bottom blade in ground contact
2. Raise height of cut
3. Nose down attitude of bottom blade
3. Re adjust cutterhead to ensure bottom
blade is parallel to ground
4. Cutterheads bouncing
4. Reduce forward speed and reduce
weight transfer
5. Worn cylinder bearings/bearing
housing pivots
5. Replace worn parts
Lines of uncut or badly cut grass in
direction of travel
6. Loose components in cutterhead
6. Check and retighten as necessary
1. Undulations too severe for height of cut
setting
1. Use floating cutterheads
Scalping
2. Height of cut too low
2. Raise height of cut
