摘要
An adjustable track tractor formed by a control and slave drive unit connected together at their front and rear ends with respective front and rear cross beams pivoted at each end thereto. Each drive unit is converted from a conventional tractor to have only a single front and rear wheel. When the cross beams are pivoted by rotary hydraulic actuators, the drive units are moved together or apart to change the wheel track.
