Abstract: A tool control system for a scraper is disclosed. The tool control system may have a tool, a first tool actuator configured to move the tool, and a first sensor configured to detect a position parameter of at least one of the tool and the first tool actuator and to generate a corresponding first signal. The tool control system may also have a tool member operatively connected to the tool, a second tool actuator connectable to the tool member in a plurality of configurations to move the tool member, and a second sensor configured to detect a position parameter of at least one of the tool member and the second tool actuator and to generate a corresponding second signal. The tool control system may further have a controller configured to make a comparison of the first and second signals, and to determine a current connection configuration based on the comparison.

Abstract: A scraper for plowing and gathering earth specifically adapted to fit to the front end of a skid steer vehicle. The scraper includes a frame for holding a scraper bowl. A caster wheel assembly is coupled to the front end of the scraper frame and is adapted to cause the scrapper bowl to adjust to the terrain. A hydraulic actuation assembly is arranged to lift the scraper bowl to carry its contents from a first site to a second site. A gate is coupled to the front end of the scraper bowl to capture the contents of the scraper bowl when its contents are moved from a first site to a second site. An implement quick-attach assembly is also provided for coupling the skid steer vehicle to the scraper frame in such a way that the frame can be made to pivot to vary the pressure between the earth being traversed and the cutting blade.
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.
Abstract: A pair of links disposed at opposite sides and rearwardly of a scraper ejector panel pivotly support the panel from the upper limit of the bowl side walls and maintain it in substantially upright position as it moves forwardly in a downward arcuate path of its lower limit adjacent the scraper bowl bottom. In the retracted position the ejector panel forms a rearward wall for the scraper bowl.
