Abstract: The Temporary Single Arm Adjustable Goose Neck Hitch system allows for a traditional tow behind trailer that has been constructed with a straight tongue or an A frame style trailer hitch, to be converted into, and function as a temporary single arm, adjustable goose neck style trailer, that can be attached to and towed by an independent self propelled vehicle such as, but not limited to, a small utility truck, an All Terrain utility Vehicle, a 5th wheel dolly assembly, or the rear hitch device of a towing vehicle such as a pickup truck by using a standard 5th wheel coupling device, the fore said hitch system uses a quick connect receiver coupler device that attaches to the traditional trailer frame hitch tongue, for the accepting of and locking in place the temporary, single arm adjustable goose neck, with the use of a temporary fastener that is inserted through the matching pre-drilled holes in the receiver coupler and the adjustable, insertable connector tube portion of the invention.

Abstract: The Quick Change Toolbar Construction Kit provides a parts based kit that when assembled systematically, and temporarily by connecting the quick change parts, one can create an unspecified number of usable toolbar configurations that can perform an unspecified number of tasks by easily transforming a single toolbar into different styles, sizes and configurations, so as to have a usable functioning toolbar that performs tasks including but not limited to tillage, seeding, material handling, landscape work or trailer towing without ever having to disconnect the main frame portion of the toolbar from the three point hitch equipped towing unit. This invention has the capability for quick expansion or reduction of the toolbar in width, length and depth. This quick expansion and reduction capability makes it possible to use the one toolbar in large or small job site applications.
