Claim:
A castor wheeled trailer for laterally rigid attachment to a standard towing hitch receiver secured to a towing vehicle comprising a T-bar hitch assembly pivotally attached to a trailer frame assembly with castor wheel assemblies removably suspended therefrom; a) where said T-bar hitch assembly is comprised of: a hitch bar and riser assembly with an adjustable hitch riser bracket slidably attached whereby alignment adjustments between said towing hitch receiver and T-bar hitch assembly can be made as required; a hitch cross bar attached to the rear side of said hitch riser bracket; with U-clamp supports attached to the rear of said hitch cross bar; b) where said trailer frame assembly is comprised of: a rectangular frame assembly of square frame rails and a round frame pivot bar as the front rail of said frame assembly with bushing material and caps located on said frame pivot bar at the appropriate locations as to align with said U-clamp supports attached to said hitch cross bar; a customizable top plate that is configured to secure a load chosen from the group of motorcycles, golf carts, ATV's, garden tractors, mowers, snow mobiles, jet skis or a box for sand, rocks, or mulch mounted to the top of said rectangular frame assembly; and spring loaded clutch plates suspended from the under side of said trailer frame assembly located as to engage a torsion clutch pad mounted to a torsion bar attached to said castor wheel assembly when it is facing directly forward; c) where said castor wheel assembly is comprised of: a heavy duty castor wheel assembly pivotally attached to the under side of a castor wheel assembly mounting plate; a torsion bar attached to said castor wheel assembly; and a torsion clutch pad attached to the top side of the distal end of said torsion bar in such a position that when said castor wheel assembly is facing directly forward, said torsion clutch pad is in spring loaded frictional contact with said torsion clutch plate, whereby high speed shimmy is eliminated.
