A dipper assembly includes a dipper having an open bottom and forward end, and a door pivotally linked to the dipper. The dipper bottom is defined by dipper wall bottom edges. The door has a bottom wall and side walls which extend above the bottom wall to define a volume between the side walls, wherein top edges of the side walls abut bottom edges of the dipper wall bottom edges to close the dipper bottom. |
