The synchronisation of the first and second transmissions (T1, T2) takes place by a result value (cal_out) of an arithmetic logic unit (140) being conducted to the second adjustment unit (ADU2) arranged at the second transmission (T2), dependent on the first transmission (T1) and on the reference value (v_set) of a preselection unit (100).

Abstract: A hydraulic system for utility vehicles is disclosed for prioritized pressure medium supply to internal and external pressure medium consumers (6, 11, 12), which are fed via load sensing spool valves (20, 26), the external pressure medium consumers (11, 12) being supplied with pressure medium via a priority valve (17). In order to improve the work quality of an implement driven by an external pressure medium consumer, the present invention provides that priority can be selectively assigned to the internal (6) or the external (11, 12) pressure medium consumers. It is thus possible for the driver, in order to ensure optimum operation of the utility vehicle in critical situations, to give priority to external pressure medium consumers. In this way during operation of an implement for dispersion of substances, better work quality can be attained, as a reduced supply and thus slower function of the internal power lift are accepted.

The tank can be displaced in such a way that access to important components is possible without complete dismantling, and, as well as this, the installation and dismantling of the tank can be designed to be easier, faster, and therefore more economical.
