Abstract: A lawnmower attachment for providing an increased cutting width on a lawnmower uses a mower deck attachable by means of a hitch to the back of a riding lawnmower, or other pulling unit, and includes the use of at least two additional lawnmower cutting blades operably powered by an independent motor mounted on the mower deck. A pair of guide wheels mounted in a spaced apart relationship are provided to support the mower deck off the ground, while a non-horizontally pivotable hitch arrangement is provided to prevent jackknifing of the attachment during a reverse movement of the riding lawnmower.
