Maintenance
Procedures to overlap the blades
Blades overlap
These rotary cutters have blades that overlap to assure the cut over the whole job area
to compensate a possible wearing on the blades, leading to cut failures. If the transmission
box (distributor or gearbox) or the supports receive a maintenance that alters the factory-
adjusted synchronism, resync the blades to assure that they will not collide when turning.
• Totally lift the rotary cutter to the third point of the tractor until it is possible to inspect
their supports.
• Turn off the tractor, brake and use chocks on the tires. Firmly immobilize the rotary
cutter on this height.
• For RC² 2600 CL and RC² 3100 CL models, remove one of the chains from the
gearbox. If you have a RC² 2600 LSL model, uncouple the cardan shaft end.
• Manually turn the blade supports until they reach an angle of
90 degrees.
• Assemble the chain/cardan shaft end on
the rotary cutter and observe the
supports position, always keeping
an angle of
90 degrees
.
• Perform a complete
turn on the blades using
your hand to assure that
they will not collide during
operation.
ATTENTION When replacing the blades,
observe that they are supplied
in pairs, which should be kept
together until assembled on
the cutter spindle. Unbalanced
blades may cause excessive
vibration and can damage
bearings, retainers and
the transmission box. The
discrepancy in weight of these
blades is within the tolerance
specified in the project.
