Abstract: An agricultural vehicle is disclosed having ancillary equipment that may be raised and lowered relative to the ground with consequential changing of the position of the centre of gravity of the vehicle and having a hydraulic braking system comprising a master cylinder and a slave cylinder. The braking system further includes a pressure relief valve for limiting the hydraulic pressure applied to the slave cylinder only when the vehicle is in road mode. This ensures that the braking force does not exceed a safe limit below which the vehicle does not risk toppling forwards when braking.

Abstract: A control arrangement for a hydraulic system is disclosed. The system comprises a variable displacement hydraulic pump (4), which is connected with a hydraulic drive motor (16) by a supply line (11) and a return line (12). The system also includes a pump controller (4a) which is adapted to vary the displacement of the pump (4). The control arrangement includes a first feedback element in the form of an oil temperature sensor (19), which provides the pump controller (4a) feedback of the evolution of the oil temperature. The pump controller (4a) is adapted in vary the displacement of the pump (4) in response to said feedback. A second feedback element is constituted by a pressure limiter valve (15c), which provides to the pump controller (4a) feedback of the pressure in at least a feedback portion (12a) of the return line (12).
