A high clearance vehicle includes a walking beam frame and an independent suspension. The frame consists of a main frame, A-shaped frames, a main truss, leg braces, and an axle. Pins which are used to join each A-shaped frame and leg braces to the main truss act as pivot points, as does the pin that attaches the axle to the main frame. Each leg brace may connect to each A-shaped frame by an elastic member to provide the independent suspension. Legs are at each corner of the frame. At the bottom of each leg is a wheel hub mount with a wheel drive assembly operably connected to a wheel for propelling the vehicle. At the top of the front legs are tapered kingpins which carry segmented thrust washers having a knob and receiving portion. A boom having extension arms and spray nozzles may also be attached. The walking beam frame may include a crab steering device which shifts the rear axle off-center so that the vehicle dog legs. A hinge stacked assembly includes a self-cleaning screen, a condenser, oil cooler, and a radiator. Angled hinges allow a door to be opened away from the vehicle and the rear tire so that the stacked assembly is easily accessible to maintenance. A knee action suspension may also provide independent suspension to the vehicle. The boom may have upper and lower lift arms. An elastic member may be provided for supporting the lower lift arm.
