Abstract: A frictional resistance measuring apparatus having a platform (28) attached to a frame (20). A pair of tandem wheels (36) are also attached to the frame (20), the combination providing a resistance surface and a rotational drive source when placed upon the ground or floor. A movable weight box (38) is slideably disposed and captivated within the frame (20) and is free to move fore and aft. A gear reduction drive arrangement in the form of gears and roller chains transmit the rotation of the wheels (36) to a linear movement when removably connected to the weight box (38). When a remote power source in the form of a model vehicle is attached to the front of the apparatus and operated, the frictional resistance of the platform (28) is increased proportionately as the weight box (38) simultaneously moves forward from the rear placing the box with weights progressively closer to the platform (28) thereby increasing the resistance providing measurement of the pulling power of the vehicle.
