A backhoe for quick connection to an end of an all-terrain vehicle (ATV) is described. A quick-connector mechanism is secured to a main mounting frame of the backhoe for securement to attaching components of an ATV. The backhoe has a pair of adjustable telescopic legs and a pivoting boom assembly, as is common with such apparatus. The pivoting boom assembly is connected to the main mounting frame of the backhoe by a piston operated pivoting mechanism for 180° lateral displacement of the boom assembly. The pivoting mechanism is comprised of a toothed sprocket secured to a vertical pivot connection at an attaching end of the boom assembly and fixedly secured to the main mounting frame. A sliding rack is provide with a series of teeth in toothed engagement with the toothed sprocket and secured for axial displacement by a fluid operated cylinder to cause the sprocket to turn and cause rotation of the pivot connection to thereby rotate the boom assembly within an arc of 180°.
