A stakedown assembly for a horizontal directional drill that multiplies the travel of a hydraulic cylinder so that the drive head travels twice the distance of the hydraulic cylinder travel. A gear pinion is pivotally attached to a top end of the hydraulic cylinder. A first gear rack is fixedly attached to a tower, and a second gear rack is fixedly attached to a drive head. The gear pinion floats between the two gear racks, thus, producing multiplication when the hydraulic cylinder is actuated. This allows the use of a shorter hydraulic cylinder and results in a smaller overall stakedown assembly height.
