ABSTRACT:
The invention is a highly maneuverable prime mover adapted for normal or orthogonal steering modes. In the normal mode true Ackermann steering is achieved. Either two or four wheel steering may be chosen. When in the orthogonal mode the vehicle is hybrid skid steered. In hybrid steering only one wheel of a side-by-side pair is steered. This greatly simplifies the necessary shifting mechanisms. Each wheel is driven by an individual hydraulic motor supplied from a main system. In the preferred version the prime mover has a turret capable of 360.degree. rotation. This turret preferably has a universal mounting capable of holding various types of lifting tools. The prime mover is especially well adapted for use with a tool head comprising an array of parallel screws or chains which can rapidly pick up, transport, and deposit objects such as container grown nursery plants.
