    • A track conversion unit for wheel-driven tractors in which the forward steerable wheels and their axle of the wheel tractor are removed from the wheeled tractor and replaced with tandem wheel units respectively secured to the forward end of the tractor--one at each side--by a bracket attachment for connection therewith. These tandem wheel units include two inflated tires with tread and at each side of the tractor, a crawler track extends about these inflated tires from a regular large size treaded rear drive wheel of the tractor for the purpose of being driven in crawler-like fashion over snowbound and rough terrain areas. With the steerable wheels detached, the tractor with the crawler track treads will be dependent upon the trailing equipment for steering the tractor, which steering equipment will be connected through hydraulic means with the steering wheel of the tractor to be available to the driver.
    • 用于轮式拖拉机的轨道转换单元,其中向前可转向轮及其轮式拖拉机的车轮从轮式拖拉机移除并替换为分别固定在拖拉机前端的串联轮单元 - 一侧在每侧 用于与其连接的支架附件。 这些串列轮单元包括两个具有胎面的充气轮胎,并且在拖拉机的每一侧,履带轨道围绕这些膨胀的轮胎从拖拉机的常规大尺寸踏板后驱动轮延伸,目的是以履带式方式被驱动 积雪和崎岖的地形区域。 随着可转向轮的拆卸,具有履带履带踏面的拖拉机将取决于用于转向拖拉机的拖车设备,该转向设备将通过液压装置与拖拉机的方向盘连接以供驾驶员使用。
