摘要： A tool lifting apparatus for gardening vehicles such as lawn mowers or the like, of the type that comprises a lever-type frame, which supports the tool and is associated with hydraulic-cylinder lifting actuators, coupled between the frame and the vehicle chassis. The lever-type frame is coupled to the vehicle chassis to perform oscillations with respect to a longitudinal axis. The lever-type frame defines a third-class lever in which the lever fulcrum is arranged to the rear of, and parallel to, the front axle of the vehicle and to the rear of the actuators.
