Abstract
A machine for filling a trench. The machine 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. A compactor assembly may follow behind the hopper and pack material into the trench. An operator controls the movement of the machine from an operator station on the machine.
