Hydraulic coupling SG 20

The design of SG 20 is such that it allows one mechanic to transfer the harrows BZSS-1 or BZT-1.0 from the working position to the transport position and back again using the tractor's hydraulic system, and the machine itself can be transported without problems both from field to field and to the machine yard on field roads or motorways. During harrowing, the design of the couplings allows the harrows to be lifted by the required amount when turning, then after turning they can be lowered without any problems, bringing them back to the working position, which excludes the presence of turning furrows on the surface of the cultivated field, and in cases when the harrows are clogged with crop residues, they can be easily freed from them by simple lifting, during which the crop residues fly off the harrow tines. If some of the crop residues are delayed, they are easily discharged by means of a water hammer.
