<p>A side loader is provided with a pair of front wheels and a pair of rear wheels on front and rear axles. Each pair of wheels is steerable by its own piston and cylinder in either of two modes controlled by a clutch. In the first mode the wheels of each pair are steered by different angular amounts for turning of the vehicle, but in the second mode the wheels of both pairs are steered by the same angular amounts so that the vehicle can move bodily at an angle, up to 90 DEG , to the normal fore and aft direction of the vehicle.</p> |
