Increasing frictional resistance to forward movement is provided by a self-propelled power stopper weight transfer apparatus comprising a four-wheeled vehicle chassis on which there is positioned an elongated mass guide upon which a gear-driven mass of up to ten tons may be moved from a position over a rearward, relatively frictionless means to a forward position over a high friction sled means. A motor power means at the front end of the vehicle chassis not only allows the apparatus to be driven on a highway and acts as a return means during a contest, but also eliminates the need for a separate dead weight on the sled means. Movement of the mass on the mass guide is produced by a direct gear drive connected in the power transmission system. A cab which may be provided on the chassis also adds dead weight. A fifth wheel arrangement on the sled, the attachment of which to the chassis may be controlled from the cab, allows rapid coupling and uncoupling of the apparatus and the sled means for simple, quick and efficient operation.
