<p>A multi-purpose four-wheel drive vehicle having four-wheel steering. The vehicle according to the present invention incorporates a number of features, some of which are individually known in the prior art but which, when combined in a single vehicle, constitute a vehicle having several advantages over conventional vehicles presently employed for various uses. The applicant's multi-purpose vehicle is of light-weight construction, is relatively inexpensive to manufacture in comparison with vehicles presently employed for the same jobs as those accomplished by the present vehicle, and has substantially less initial and operating costs. The applicant's vehicle incorporates a relatively high ground clearance which is achieved by employing four vertical axles and wheels situated at the four corners of a main frame body of the vehicle. The vertical axles are situated in respective spaced-apart leg post members, each leg post member being rigidly interconnected by two spaced-apart longitudinally extending frame members and two spaced-apart transversely extending frame members. At least three of the frame members are of torsionally resilient construction. When a weight is suspended mid-point between the front and rear wheels of the vehicle, this weight may be transferred by the vehicle without traction loss due to the increased load in that true traction is increased as the load increases.</p> |
