Abstract
A machine for filling a trench comprises a tub, release assembly, and a hopper. The tub mixes a material to be filled into the trench. The release assembly releases the material into the hopper and the material flows from the hopper and into the trench. The machine moves parallel to the trench as the trench is being filled. An operator controls the movement of the machine from an operator station on the machine.
