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.
