A hydraulic steering arrangement (1) is described comprising a supply port arrangement having a pressure port (P) and tank port (T), a working port arrangement having two working ports (L, R), a steering unit (2) arranged between the supply port arrangement and the working port arrangement and a steering valve (3) arranged between the supply port arrangement and the working port arrangement. Such a steering arrangement should have a safety means. To this end in a manual steering mode the steering valve (3) is connected to the working port arrangement through the steering unit (2).

A work machine having a cab coupled to a frame, a steering system coupled to the frame, a controller configured to selectively articulate the steering system, a joystick assembly positioned in the cab and in communication with the controller, a steering wheel assembly positioned in the cab and configured to selectively articulate the steering system, and a steering wheel sensor coupled to the steering wheel assembly and in communication with the controller to identify movement of the steering wheel assembly. Wherein, the controller does not articulate the steering system responsive to movement of the joystick assembly when the steering wheel sensor identifies movement of the steering wheel.

A tracked vehicle includes a pilot control module which enables the pilot to steer the tracked vehicle using an existing joystick of the tracked vehicle. The tracked vehicle also includes a dual track drive pedal which drives the tracks of the vehicle simultaneously. The joystick is used to make steering corrections when utilizing the dual track drive pedal.

A multiple-drive vehicle comprises a first driving position (3) for a first driver provided with first driving means (4), a second driving position (5) for a second driver provided with second driving means (6), a first pair of wheels (9) mechanically connected to the first driving means (4) and a second pair of wheels (10) mechanically connected to the second driving means (6). The first driving means (5) and the second driving means (6) are independent of each other for moving the respective pairs of wheels (9, 10) in an independent manner from each other;
