摘要： The device for regulating ground clearance of a working unit of an agricultural machine includes a position sensor (11) which detects a position of the working unit (2) relative to the machine and generates a working unit position signal; a pressure sensor (10) which generates a control element pressure signal; a ground clearance sensor (9) which issues a corresponding ground clearance sensor output signal in a contactless manner; and a control device (7) for operating the control element to set the ground clearance according to the ground clearance sensor output signal alone in a first range closest to the ground, according to the working unit position signal alone in a second range furthest from the ground and according to a combined signal in a third transitional range between the first and second ranges, which is equal to a mixture of the ground clearance sensor output signal and the working unit position signal and which varies continuously from the first range to the second range.

摘要： An agricultural pulling machine such as a tractor or construction machine vehicle with an attachment comprises a mounting device for coupling the attachment to the agricultural machine and a device for active damping of pitch vibrations of the vehicle. The device for active damping including a power lift for moving the mounting device and a regulating device which controls movement of the mounting device in the region of its lifting position in dependence upon the vibrations of the vehicle during travel, and a force sensor producing signals to which the regulating device responds. The mounting device includes a lever, a housing of the vehicle and a side guiding member connecting the lever with the housing of the vehicle. The force sensor is arranged in a force flux of the lever between its connecting point to the housing and a supporting point of the side guiding member, wherein the regulating device is provided with a means for reducing disturbing influences on an operation of the vibration damping device during travel over a curve by the vehicle.
