General description
The deck are equipped with two synchronised rotating blades. The tracks of adjacent
blades are overlapping each other, which means that the synchronization is vital.
All shafts/pulleys are pivoted in sealed and permanent lubricated ball bearings.
All decks are provided with a quick-coupling to simplify the lifting up procedure for cleaning
and inspection and. The decks are also provided with an electrical or manual adjusting
device for the cutting height.
All decks are tested prior to delivery and are delivered as completely assembled as
possible. This ensures that assembly on delivery is rapid and simple.
This chapter describes how to repair and adjust the cutting device assembly.
For information on how to install it on the main machine and for information on periodical
maintenance and cleaning operations, please refer to the INSTRUCTION MANUAL.
Safety
To reduce the risk of accidental injury in the event of a collision and to protect important
parts in the cutting deck, a force limiter is integrated as follows.
• Shear bolts between blades and blade bar.
• Torque limiting between gear wheels and blade shaft.
• Possibility of positive drive belt slipping on the plastic gear wheels.
