An earth moving machine is adapted to be pulled behind a tractor or other powered vehicle. The earth moving machine comprises a hitch at a forward end thereof adapted to be connected to the tractor and an axle assembly at a rearward end thereof. A trough-shaped scoop is pivoted on a frame of the earth moving machine at a point intermediate the forward and rearward ends thereof. A first hydraulic cylinder assembly is operable to control the height of the axle assembly relative to the frame, while a second hydraulic cylinder assembly is operable to pivot the trough-shaped scoop relative to the frame. By controlling the fluid pressure supplied to the first and second hydraulic cylinder assemblies, the scoop on the earth moving machine can be used to effect scraping, levelling, digging, carrying, and dumping of dirt. When the scoop is pivoted to its scraping position, a blade provided on the scoop for selectively cutting into the ground surface is located at a position rearward of the pivot point of the scoop.

An earth moving machine adapted to be towed behind a powered vehicle, comprising: a frame member comprising a forward end and a rearward end; hitch means disposed at the forward end of the frame member and adapted to be connected to the powered vehicle for permitting the earth moving machine to be pulled by the powered vehicle; a suspension member connected to the frame member, the suspension member having a displaceable portion which is movable relative to the frame at least in a vertical direction; a wheel assembly secured to the displaceable portion of the suspension member, the wheel assembly comprising a plurality of wheels adapted to roll along a ground surface on which the earth moving machine travels; a scoop comprising a pair of side plate sections rigidly joined to opposite ends of a trough-shaped section and defining a scoop opening, the scoop being pivotally mounted relative to the frame about a pivot location on the frame intermediate the forward and rearward ends thereof, wherein the trough shaped section comprises a scoop lip portion located adjacent the scoop opening to which at least one blade means is attached for selectively cutting into the ground surface; a first motor means for controllably moving the displaceable portion of the suspension member relative to the frame member so as to controllably vary the vertical position of the displaceable portion relative to the frame member the first motor means being connected to the frame member at a position rearward of the scoop; and a second motor means for controllably pivoting the scoop relative to the frame so as to controllably vary the orientation of the scoop opening relative to the frame member, the second motor means being operative to controllably pivot the scoop between a first and a second position, wherein in the first position, the scoop is oriented such that the scoop opening faces generally upwards and the scoop is effective for carrying a load as the earth moving machine travels along the ground surface, and in the second position, the scoop is oriented such that blade means is positioned rearwardly of the pivot location of the scoop and the scoop is effective for facilitating scraping and levelling of dirt.
