Abstract
A high-clearance dump system is described for use with a riding mower. A folding lift assembly lifts the catcher box up and away from the riding mower to allow dumping over and away from the walls of a truck or other receiving vehicle. The folding lift assembly interfolds into the dumping catcher assembly and the dump system mount assembly thus providing a low-profile when in the lowered position. A lift pivot arm, and lift control rods that are shorter than the lift pivot arm, cause the catcher frame to be tilted at an obtuse angle with respect to the lift pivot arm so that the back end of the catcher frame is higher than the front end of the catcher frame when the lift pivot arm is raised, thus providing high clearance. A power system provides power a switch box that switches power between a lift cylinder and a dump cylinder so that the catcher may be dumped in a raised, partially raised, or lowered position.
