4.4 Compressing a big bale
The machine is able to compress hay and straw to a highly compacted big bale (square bale).
The square baler is compressed in 9 steps.
1. The pick-up gathers the crops.
2. The crop press roller unit and the intake roller behind it make sure that crops can be picked
up properly.
3. The integrated intake roller conveys the crops to the cutting rotor and then further to the
packer drum.
4. The packer drum fills the feed channel.
5. When a determined filling level has been reached, the sensing rake is swung back and the
bale channel is filled via the feeder strip with the crop.
6. The crops are pressed in the bale channel to a highly compacted big bale.
7. The knotting mechanism is triggered and the big bale is tied after the set bale length has
been reached.
8. The next big bale conveys the big bale further to the bale chute. From the bale chute, the
big bale is laid down on the field.
9. The last big bale is conveyed to the bale chute via bale ejector.
