Abstract

Agricultural or work vehicle comprising an internal combustion engine (E), an electro-hydraulic circuit (HC) for powering at least one hydraulic actuator (Al - A3) by means of a respective closed-center control valve (V1 - V3), comprising a first hydraulic pump (P) operatively connected to the internal combustion engine (E) to be driven in rotation by it to power said valves (V1 - V3) by means of a hydraulic supply line (PP), a transmission having a hydrostat (HY) comprising a second hydraulic pump (HP) operatively connected to the internal combustion engine (E) to be driven in rotation by it and a pair of hydraulic lines (F, R), wherein the first hydraulic pump has a variable displacement with a displacement value that is a function of a sensing signal generated by a sensing line (LS) connected downstream of said control valve (V1 - V3) and by a supply pressure signal generated by the supply line (PP). A compensation valve (A) is arranged to connect said pair of hydraulic lines (F, R) with said supply line (PP), wherein the compensation valve is controlled as a function of the sensing signal and the supply signal.
