Abstract
A wheelbarrow with a drainage system. A drainage hole is drilled into the wheelbarrow tray. A flange is positioned over the predrilled hole. The flange has a contoured track and a flange opening. An elbow is positioned under the predrilled hole and is connected to the flange. The elbow has a ball bearing connected to the elbow and inserted into the contoured track. A removable drain plug is connected to the elbow and plugs the flange opening when the drainage system is in the closed position and unplugs the flange opening when the drainage system is in an open position. The drainage system is moved from the closed position to the open position by turning the elbow. The ball bearing then moves along the contoured track and causes the drain plug to move between plugging and then unplugging the flange opening.
