Abstract
A system for accelerating the front wheels of a vehicle, eg an agricultural tractor, on turning a corner, comprises steering angle sensors (21) which, via a control unit (22) enable or disable drive to the front wheels from a hydraulic motor (11). The drive from the hydraulic motor from the front wheels is via a one-way clutch (14). The hydraulic motor (11) is powered by a pump (6) driven either directly from the vehicle engine or from the main transmission.
