The vehicle (10) has a steering arrangement which allows the vehicule to be steered merely by selectively driving the left and right wheels. The steering arrangement (18, 19, 22, 23) requires at least one of the front and rear pairs of wheels (12, 13) to be castor mounted so as to be freely pivotal around respective pivot pins (18), with the pair of castor mounted wheels (12, 13) being linked (22, 23) so that they pivot generally in unison. Preferably, each of the castor mounted wheels (12, 13) rotate in a vertical plane which is laterally spaced from the pivot pins (18). |
