A snubber system for retarding a swinging movement of a door with respect to a body of the dipper. The snubber system includes a braking assembly, an arm structure, and a link structure. The braking assembly is configured to be fixedly mounted to the body. The arm structure is configured to execute rotation about a first axis, the rotation of the arm structure being dampened by the braking assembly. The link structure is rotatably coupled to the arm structure to rotate about a second axis, and is movable in correspondence with the swinging movement of the door to exert and transfer a force to the arm structure. A direction of the force defines an angle between 80-100 degrees with respect to an axis or a plane passing through the first axis and the second axis throughout the swinging movement of the door.
