Abstract
An implement lift system for a machine such as a front mouted mower having a pair of transversely spaced lift arms operable by a single life cylinder. The lift cylinder is transversely adjustable utilizing a special cylinder bracket arrangement and a transverse member extending between bend locations on the lift arms forwardly of the pivotal connections of the lift arms with the vehicle. The transverse member is connected to provide lift to both arms from the single cylinder while permitting independent vertical movement of each of the arms. Compensation for unequal forces acting on the lift arms can be provided by moving the cylinder laterally to achieve even lift and flotation characteristics.
