Abstract
An earth mover includes a fixed scraper blade and a moveable floor section. The moveable floor section can be pulled rearwardly to provide an opening between the fixed scraper blade and the forward edge of the floor section. The floor section is mounted on tracks which run on the exterior of the sidewalls of the bowl. The forward portion of the tracks are angled upwardly which keeps the floor tight against the bottom of the bowl. When the floor is in the open position, it allows the floor to extend downwardly below the thick scraper blade. This allows the forward edge or blade of the floor section to act as a leveler as the dirt is being unloaded from the earth mover.
