The trailer is equipped with the drawbar with hydraulic shock absorption and smooth height
adjustment for connecting with tractor hitches (hitch, piton fix, transport hitch, ball hitch).
TIP
The hydraulic system of the drawbar is filled with L-HL32 Lotos hydraulic oil.
The drawbar's hydraulic system is supplied by the tractor's external hydraulic system through
the hydraulic conduits which are connected to the sockets of a single section of the tractor's
hydraulic system by means of quick couplers (1). Rising or lowering the drawbar is carried
out in order to level the trailer and is done by withdrawing or extending the hydraulic cylinders

bar. The purpose of the accumulator is to amortize vibrations transferred to the tractor.
