ABSTRACT:
An elongated single-unit vehicle having a steering system that provides increased vehicle maneuverability at slow speeds. The vehicle has a front steering axle connected to steerable front wheel assemblies, an auxiliary steering axle connected to steerable wheel assemblies and positioned rearward of the front steering axle, and a rear axle and wheel assemblies rearward of the auxiliary steering axle and positioned at the rear portion of the vehicle. A remotely adjustable linkage assembly is coupled to the front and auxiliary steering axles and connected to the steerable front end auxiliary wheel assemblies, so the ratio of the degree of wheel turn of the front wheels to the degree of wheel turn of the auxiliary wheels can be adjusted from a remote position, such as the driving compartment of the vehicle. An axle lifting mechanism is connected to the front steering axle and adapted to move the steerable front wheel assemblies between a lowered position, wherein the wheel assemblies engage the ground, and a lifted position, wherein the front wheel assemblies are off the ground.
