8.15 Maintaining the reels
8.15.1 Checking the mowing units
Check the mowing units regularly to ensure the cutting quality.
CAUTION!
• Always wear protective gloves when performing a service function on or near a mowing unit. Severe injury
can result from contact with sharp cutting edges.
• When a mowing unit is rotated by hand it is possible that the other mowing units may rotate as well.
Materials needed:
• Several strips of paper (80 g/m
2
).
1. Raise the mowing units to get access to
the underside of the mowing units.
2. Lock the front mowing units with the
transport and safety brackets.
3. Park the machine safely, turn off the
engine and remove the ignition key.
4. Place a double-folded sheet paper at a
right angle on the bed knife.
5. Turn the mowing unit (very carefully!) by
hand in the cutting direction.
The paper sheet should be cut cleanly
over its entire length.
6. Repeat steps 4 and 5 over the entire
length of the bed knife.
The adjustment is correct when at least one sheet of paper is cut completely. A slightly audible contact between the
cutting knife and the bed knife is allowed. When no paper strips are cut completely or the cutting knife and bed knife
overlap, adjust the cutting cylinders.
