ABSTRACT:
The present invention is an improved trailer for processing items. The trailer includes a frame, translating wheel assemblies and a pivoting hitch assembly. Each translating wheel assembly includes a stationary portion fixed to the frame and a translating portion for carrying at least one wheel. The translating portions of the wheel assemblies move up and down between a first extended position in which the wheels support the frame of the trailer and a second retracted position in which the frame sits on the ground. The hitch assembly includes an arm for coupling the trailer to a tractor vehicle. The arm moves between a first trailering position and a second stowed position. The arm is pivoted into the stowed position so that it does not interfere with process items entering or leaving the trailer.
