The machine is equipped with an electrical knotter monitoring. In this process, each knotter is
monitored individually by a sensor (1). An error message appears in the display of the terminal if
a fault occurs at the knotter,
The knotters are numbered from 1 to 5 in direction of travel from left to right.
Knotter gearbox
BP000-071 / EQ000-072
Knotter gearbox in idle position
The knotter gearbox is in idle position if the trigger roller (1) is located in the recess of the cam
disc (2) of the knotter gearbox.
Tying process
The tying process consists of one rotation of the cam disc (2). The system automatically triggers
the knotting mechanism after the set bale length has been reached. In this process, the cam
disc rotates, presses the trigger roller out of the recess and continues to rotate until the trigger
roller slides into the recess again. While the cam disc rotates, the first knot (closing knot) is tied
at first and immediately after that the second knot (starting knot) is tied.
1st knot: Closing knot, ties the pressed big bale.
2nd knot: Starting knot, ties the initial knot for the next big bale.
Initiating the tying process manually
In case of maintenance, setting or repair work, the tying process can be manually initiated when
the tractor is not connected. The tying process is carried out by manually turning the flywheel
(3) in working direction (I);
