Abstract: In the case of a mounting device for mounting a support arm, which moves a lifting tool, on a harvesting machine, a cylindrical bushing is mounted on a machine part. The bushing is enclosed by a retaining element on which the end of the support arm opposite the lifting tool is fixed. The bushing has a through-hole that receives a machine part and has an axis of symmetry extending eccentrically relative to the axis of rotation of the cylindrical bushing.

Abstract: A system for an agricultural machine for displaying machine-specific information and inputting machine-specific commands comprising a programmable electronic control unit (1) comprises a microcontroller having an interface for connection to a bus system (2) belonging to the machine. The control unit (1) further comprises wired or wireless communication means for setting up a wireless or wired communication connection (4) to a mobile computer unit (3), such that the control unit (1) is connected for data exchange to the mobile computer unit (3). The control unit (1) is connected, on one hand, to a tractor control device (5) and other participants (6) of the bus system (2) by means of the machine's bus system (2), and on the other hand to the mobile computer unit (3). The mobile computer unit (3) is used for displaying machine-specific information and inputting machine-specific commands.

Abstract: A motor arrangement on the steering wheel of a vehicle has a motor, a friction wheel drivable by the motor and engagable against the steering wheel, and a motor mount having a main support that is securely connectable to the vehicle and a motor support that is mounted on the main support for pivotal movement about an axle and is securely connectable to the motor, and a spring bearing against the main support and the motor support and attempting to turn the motor support relative to the main support in a direction of engagement. The motor arrangement includes a locking device which limits the pivoting movement of the motor support relative to the main support, adopts a locked position upon reaching a first pivot angle as the result of a pivoting movement of the motor support in the direction of disengagement, and is unlockable by a pivoting movement in the direction of disengagement which exceeds the first pivot angle by a second pivot angle.
