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.

Pollutant abatement system (ATS) produced comprising in succession, from an exhaust gas inlet point (IN) and an outlet point (Out) of purified exhaust gas, a first SCR selective reduction catalyst (SCR_1), a diesel oxidation catalyst (DOC), a particulate filter (DPF), a second SCR (SCR_2), connection means (DV1, V2, V3, L1, L3a, L3b) configured to bypass the first SCR (SCR_1).

Agricultural or work vehicle comprising a hydraulic steering system (SS), at least one hydraulic working tool (HU) and a first hydraulic pump (P) for supplying the steering system by means of a hydraulic supply line (SL) and the at least one hydraulic working member, a hydrostat (HY) comprising a second hydraulic pump (HP) and a hydraulic motor (MP) operatively connected to at least one vehicle wheel (W), wherein the second hydraulic pump and the hydraulic motor are interconnected by means of a pair of hydraulic lines (F, R) and comprising a switching valve (SWV) arranged to connect said pair of hydraulic lines with said steering system in place of said first hydraulic pump, in conditions of failure of the first hydraulic pump.

Hydraulic circuit (HC) for an agricultural or work vehicle, wherein the agricultural or work vehicle comprises at least one working part such as an arm, a hydraulic lift, etc., a braking system (BI) comprising service braking means (7) and parking braking means (3, SAHR), and a user interface (14) for receiving a braking request from a user of the vehicle; wherein the hydraulic circuit comprises a variable displacement hydraulic pump (1), operatively connected to a directional valve assembly (4) for supplying said at least one working member, comprising a discharge valve (2) for recirculating hydraulic oil through cooling means, wherein said braking system comprises at least one braking valve (7) for actuating said service brake, operatively connected to said hydraulic pump, said parking braking means are configured to activate in response to said braking request, when a fault in said service braking means (7) is detected, said discharge valve is set so that an opening pressure threshold of the discharge valve is greater than a maximum supply pressure value of said at least one braking valve (7).

Method of supporting the completion of a mission of an agricultural or work vehicle operated by a computer, wherein the vehicle is equipped with an articulated arm (A) connected to a chassis (F) of the vehicle such as to assume a plurality of operational configurations, a propulsion system such as to allow movement of the vehicle with respect to a support surface, the method including monitoring (step 1) of a mission of the vehicle within a continuous and predetermined time interval and when it appears (steps 2 and 3) that the mission coincides with a pick & place mission, then the method comprises a step of suggesting (step 4) to the user or automatically operating the activation of a function of parallel movement of forks operationally connected to said articulated arm.
