A supporting wheel substitute or track drive conversion apparatus is connectible to a driven wheel of a vehicle having a support frame. A frame is pivotally connectible to the support frame of the vehicle for movement in a vertical plane relative to the support frame of the vehicle. An end wheel is positionable spaced longitudinally from the driven wheel of the vehicle along the frame. Adjustable members selectively secure the end wheel in various longitudinal positions along the frame with respect to the driven wheel of the vehicle. An endless, flexible track is trainable over the end wheel and the driven wheel of the vehicle and is engageable with a surface over which the vehicle is traveling.
