Abstract
A wheeled dump cart is described which may be dumped from the user's normal position behind the handle. The cart includes a box member pivotably connected to the frame. A cam member may be pivoted from a normal raised position to a ground-engaging position. The cam member engages the box member and causes it to pivot forwardly relative to the frame so as to dump the contents of the cart.
