Abstract: A trailer that includes a belts that each encompass a front wheel and a rear wheel and have a ground engaging surface and a wheel engaging surface, the wheel engaging surface having lugs thereon for mating with the apertures in the front wheel and the rear wheel such that when the at least one of the front wheel or the rear wheel rotates, the belt is positively driven and at least one belt tensioning system for maintaining tension on the plurality of belts, the at least one belt tensioning system includes a track tension cylinder operatively mounted between an axle of the at least one of the front wheel or the rear wheel and the main frame, wherein the track tension cylinder maintains tension on the belt by moving the axle of the at least one of the front wheel or the rear wheel in a horizontal.

Abstract: A military vehicle, e.g., tank, that includes a turret, a gun mounted on the turret, a plurality of belts, wherein each of the plurality of belts encompass a front wheel and a rear wheel to provide a positive belt drive system for rotating the belt, at least one suspension system for absorbing load stresses, each suspension system having a suspension cylinder that is operatively and pivotably mounted to a military vehicle frame pivot on a main frame of the military vehicle, at least one belt tensioning system for maintaining tension on the plurality of belts, by moving the axle of the at least one of the front wheel or the rear wheel in a horizontal direction, and at least one electric drive system that includes electric drive motors for rotation of the at least one of the front wheel and the rear wheel and braking.

Abstract: A tractor that can pull a wide variety of equipment such as that for tilling, seeding and fertilizing of field crops. The equipment can also include reservoirs for containing large quantities of seeds and fertilizers such as liquid manure. As tilling and fertilizing progresses these materials as dispensed changing the weight distribution on the tractor. The change can be compensated for during use by sensing weight and adjusting the position of the machine connecting structure in response thereto, such as a fifth wheel of the tractor, in real-time, to generally equalize weight distribution.
