ABSTRACT:
Cargo in the nature of a farm machine, such as a grain drill, is combined with transport structure in the form of a mobile carrier to improve upon over-the-road travel and other movement in a manner to permit rolling support by the ground wheels of both the carrier and the machine during the towing operation. The carrier has a normally inclined bed to facilitate loading of the machine thereupon. Power means, for example, that with which the machine is equipped to control depth, is then used to raise the lower end of the carrier off the ground prior to coupling the carrier-machine unit with a tractor or other towing vehicle.
