A hydraulic system for a work vehicle has a high pressure circuit for providing high pressure hydraulic fluid, a medium pressure circuit for providing medium pressure hydraulic fluid, and a low pressure hydraulic circuit for providing low pressure hydraulic fluid. The high pressure circuit has a variable displacement charge pump that provides pressurized hydraulic fluid only to a high pressure variable displacement pump according to demand, which provides the further pressurized hydraulic fluid to a priority valve according to demand. The medium pressure circuit has a medium pressure variable displacement pump that provides pressurized hydraulic fluid according to demand. The low pressure circuit has at least one low pressure variable displacement pump that provides pressurized hydraulic fluid by way of an oil cooler and/or an oil cooler bypass controlled by a proportional valve.

An off-road vehicle includes a chassis, an axle carriage, a rigid axle and a pair of suspension cylinders. The axle carriage is attached to or forms a part of the chassis, and includes a generally vertically arranged slot. The rigid axle is mounted to the axle carriage with a wheel hub at each end thereof, and is vertically movable relative to the axle carriage. The suspension cylinders are connected between the axle carriage and axle, and are operable to move the axle in vertical directions relative to the axle carriage. The off-road vehicle is characterized in that the axle includes a first pair of roll angle stops which engage the axle carriage when the axle is at or near a fully lowered position relative to the axle carriage, and a second pair of roll angle stops which engage the axle carriage when the axle is at or near a fully raised position relative to the axle carriage.

A brake and steer-by-braking pedal arrangement for tractors includes a right pedal and a left pedal operating synchronously or diachronically; and at least one hydraulic or pneumatic circuit connected to one master cylinder activated by at least one of the pedals. The pedal arrangement also has potentiometers connected electronically to an electronic central control unit and the potentiometers determine the distance between the pedals The electronic central control unit determines, on the basis of data received from the potentiometers, whether or not to activate the steer-by-braking function.

A parking brake having an electromechanical and hydraulic device for gripping a pack of movable sectors connected mechanically to the wheels to exert the desired braking force on the wheels. The parking brake is characterized by having an oil flow regulating valve assembly, in turn having a first control solenoid valve and a second safety solenoid valve in series with each other.
