A track-laying auxiliary thrust unit is connectable to a steerable wheeled or skid-mounted vehicle to add thrust and reduce the per unit area force on the ground. Various couplings are disclosed for interconnecting the thrust unit with the vehicle. The thrust unit derives its primary power from the vehicle which it is assisting through hydraulic hoses, a mechanical connection or an electrical interconnection. Thrust units in accordance with the invention are particularly useful in agricultural contexts for towing large and heavy agricultural implements with a tractor of modest capability.
