ABSTRACT:
An adjustable vehicle counterweight device (10) with cylinder positioning means (62). The vehicle counterweight device (10) comprises a frame (16) for being secured to a motor vehicle, such as a tractor (12), and comprises a weight member (14) reciprocatably supported by the frame (16) such that the weight member (14) is laterally reciprocatable and selectively positionable along a path of travel substantially parallel to the axis of the axle (13) of the tractor so as to allow the selective alteration of the center of gravity of the tractor (12). The device (10) also includes means for selectively moving the weight member (14) along its path of travel, which, in the preferred embodiment, comprises a hydraulic cylinder (22) provided with cylinder positioning means (62) for adjusting the axial position of the cylinder portion (24) of the hydraulic cylinder (22) to alter the range of travel of the weight member (14).
