ABSTRACT A converter assembly for converting a drive-wheel-driven tractor into a track-driven tractor, the assembly having its frame separate and unattached relative to the frame of the tractor and constructed and arranged, together with a continuous track, to be positioned beneath the drive-wheel of the tractor, and within the track, in cooperating position with the drive-wheel and track, to effectively extend the ground-engaging area of the tractor. A pair of transversely spaced, relatively light, plate members rotatably mount a pair of idler wheels, one ahead and one behind the drive-wheel within the track. A pair of alignment rollers are also rotatably mounted between the plate members in engaging and aligning relation ahead and behind the drive-wheel, whereby the converter assembly is maintained in aligned relation with the drive-wheel, and some of the weight is transferred from the drive-wheel, through the alignment rollers and plate members, to the idler rollers. The plate members permit easy application of the converter assembly to, or withdrawal from, the drive-wheel by merely jacking the latter into an elevated position and applying or removing, as the case may be, the converter assembly and track by merely removing the outside plate member before applying or removing the assembly form the drive-wheel, and re-applying same after the lower portion of the drive-wheel is extended into the track and assembly or is removed therefrom, as the case may be. The entire converter assembly is otherwise entirely unattached relative to the frame of the tractor.
