An ability to move a wheelbarrow without lifting the rear part of the wheelbarrow is achieved by attaching a handle adapter that extends upward from the rearwardly extending handles of the wheelbarrow. Further, a converter kit converts a conventional single wheeled wheelbarrow into a three wheeled device. The handle adapter is a tubular construction and can be easily detached from the wheelbarrow. In one embodiment of the converter kit, a plate and a hollow tube are attached to generally U shaped resting arms for easy assembly and disassembly of auxiliar...

1. A three wheeled wheelbarrow with handle adapter comprising:a container; a tubular structure forming a base frame of the wheelbarrow, whereby said frame is attached rigidly to said container; a pair of first handles extending from both free rear ends of said base frame; a wheel attached to a front end of said tubular structure; a pair of generally U shaped resting arms extended downwardly from a bottom rear portion of said container, whereby free ends of said generally U shaped resting arms are rigidly mounted to said tubular structure; a pair of plates attached vertically to the said pair of generally U shaped resting arms, whereby each said plate has a slot extending therethrough; an elongated axle mounted through said slots in the plates; a pair of removable wheels mounted to said elongated axle; and a second handle of higher height than said pair of first handles mounted to said pair of first handles for easy tilting, pushing or pulling said wheelbarrow without bending or lowering the body and to move said wheelbarrow without lifting the rear end of said wheelbarrow; wherein said second handle first bends vertically at proximal ends near to said pair of first handles and second bends horizontally relative to said first handles in an arch to form an adapter handle of about the same width as the separation of the pair of first handles. 2. The three wheeled wheelbarrow with handle adapter as claimed in claim 1, wherein said wheelbarrow further has a pair of strips which are attached to both a front of said container and said front end of said tubular structure for stability.3. The three wheeled wheelbarrow with handle adapter as claimed in claim 1, wherein said proximal ends are detachably attached to said first handle.4. The wheelbarrow as claimed in claim 1, wherein said elongated axle has an aperture extending into it at opposite free ends to allow quick release pins to attach thereto.5. The wheelbarrow as claimed in claim 4, wherein said quick release pins prevent said removable wheels from slipping outward.6. The wheelbarrow as claimed in claim 1, wherein said slot is a G-shaped slot which enables the user to use the wheelbarrow as a three wheeled wheelbarrow or to station said wheelbarrow on its generally U shaped resting arms.7. A three wheeled wheelbarrow with handle adapter, comprising:a container; a tubular structure forming a base frame of the wheelbarrow, whereby said frame is attached rigidly to said container; a pair of first handles extending from both free rear ends of said base frame; a wheel attached to a front end of said tubular structure; a pair of removable wheels mounted to said tubular structure; and a second handle of higher height than said pair of first handles mounted to said pair of first handles for easy tilting, pushing or pulling said wheelbarrow without bending or lowering the body and to move said wheelbarrow without lifting the rear end of said wheelbarrow; wherein said second handle has two proximal ends and four bends, said proximal ends are detachably attached to said first handle; wherein said four bends of said second handle include first two bends bent approximately 125 degree vertically near to the proximal ends and second two bends bent approximately at a right angle horizontally between the first two bends, forming an adapter handle of about the same width as the separation of the pair of first handles. 8. A three wheeled wheelbarrow with handle adapter, comprising:a container; a tubular structure forming a base frame of the wheelbarrow, whereby said frame is attached rigidly to said container; a pair of first handles extending from both free rear ends of said base frame; a wheel attached to a front end of said tubular structure; a pair of removable wheels mounted to said tubular structure; and a second handle of higher height than said pair of first handles mounted to said pair of first handles for easy tilting, pushing or pulling said wheelbarrow without bending or lowering the body and to move said wheelbarrow without lifting the rear end of said wheelbarrow; wherein said second handle has two proximal ends and four bends, said proximal ends are detachably attached to said first handle; wherein said proximal ends are detachedly attached to said pair of first handles by an arch and a pair of nuts attached inside the tubular construction, and positioned at the proximal ends, said pair of nuts attached to the pair of first handles by a pair of bolts threadedly coupled to the pair of nuts through apertures in the pair of first handles.
