Abstract

A four wheel steer gantry vehicle which includes a pair of wheels (12) at each end of an elongate middle section (10). The vehicle is drivable and steerable in a first mode in which the vehicle moves substantially in its longitudinal direction and in a second mode in which the vehicle moves substantially transverse to its longitudinal direction. The steering system of the vehicle comprises two pairs of wheels, each wheel being independently steerably mounted and the mounts of the wheels of each pair of wheels being connected together by a hydraulic tie bar (15). Each wheel (12) is mounted such that it can undergo steering rotation by about 180°. The wheels (12) are steered by hydraulic steering actuators. The vehicle has two end sections (120) joined to the middle section (10) and a hydraulic power back up system. RTK-DGPS antennae executing synchronised sampling can be used for controlling tracking of the vehicle relative to crop rows.
