    Abstract: A waste collection system including a trailer and a towing vehicle which is selectively interconnectable with the trailer. The trailer, which may be divided into a number of separate interior compartments, has a prow-shaped forward end wall which extends beyond and above the trailer hitch to enlarge the material-receiving capacity of the trailer. A towing vehicle is disclosed which can selectively elevate and tilt the trailer sufficiently to dump the contents of the trailer. An alternative towing vehicle is disclosed which provides a trailer hitch having a limited extent of vertical adjustment necessary to raise and lower a parking support associated with the trailer. The trailer is provided with a ground support stand which is automatically locked in downward support position.
