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.
