Abstract: Two or more tractor vehicles are disposed in a highly stable unitized side-by-side relationship to apply increased tractive effort to a single working implement such as a bulldozer blade. Disengageable bracing structure couples the adjacent tractors to maintain parallelism and a pre-determined longitudinal relationship without subjecting localized regions of the assembly to excessive stress. In a preferred form, the bracing maintains these relationships while providing for independent oscillations of the tractors in response to terrain irregularities.

Abstract translation: 两台或多台拖拉机车辆以高度稳定的并排关系布置，以将增加的牵引力应用于诸如推土机叶片的单个作业工具。 可拆卸的支撑结构将相邻的拖拉机联接以保持平行度和预定的纵向关系，而不会使组件的局部区域过度受力。 在优选形式中，支撑件维持这些关系，同时响应于地形不规则性而提供拖拉机的独立振荡。
