Spring defections of the axes are braced by cable 11 and secured via hydraulic cylinder 6 before supporting beams 13 are extended. Pressure-tight check valves 10 prevent any slackening of this locking position. During a subsequent supporting operation the hydraulic reaction pressure applied in the spring locking cylinder 6 from the supporting operation is used as a control variable in respect of s...

A drive unit 1 for driving agricultural implements or effecting the drive in agricultural implements, has an input shaft 4 and at least one output shaft 10, 10a and a torque measuring device associated with at least one of the shafts 4 or 10, 10a. The shafts 4, 10, 10a are rotatably held in two spaced bearings 5, 6, 13, 14. To determine shaft twisting as representative of the shaft torque, strain ...
