Abstract: A wheeled work vehicle (1) comprising a fon/vard part (3) and a rearward part (5) pivotally coupled together for steering thereof supported on pairs of rearward and fon/vard ground engaging wheels (34, 87) carried on respective suspension arms (27, 88). The suspension arms (27, 88) are pivotally coupled to chassis (12, 14). An electrically powered motor (32, 95) mounted on the second end (29) of each suspension arm (27, 88) extends into a wheel well (52) with a wheel rim (50) of the corresponding ground g engaging wheel (34, 87). The wheel rims (50) are secured to coupling plates (47) of the motors (32, 95). The axial length of each motor (32, 95) is such that substantially the entire motor fits within the wheel well (52). The tracking and camber of each ground engaging wheel (34, 87) is adjustable by engaging appropriate ones of a plurality of selectable adjustment elements (70) in secondary bores (80) in inner and outer mounting brackets (58, 59) on which the suspension arms (27, 88) are pivotal.
