Lawnmower jack device assisted by an outboard mounted cylinder

摘要

A lifting and/or tilting device is provided for a grass cutting machine, such as a ride-on mower. The device includes a fixed chassis element designed to rest on the ground. A movable chassis element is capable of accommodating at least one wheel of the machine and is movable about an axle supported by the fixed chassis element, between a stowed position, in which the movable chassis element extends essentially in the plane formed by the fixed chassis element, and at least one raised position in which the movable chassis element is separated from the fixed chassis element. The device has a cylinder with a body that is attached permanently to the fixed chassis element and a shaft that is movable relative to the body, attached permanently to the movable chassis element, and mounted in such manner that in the raised position it extends essentially outside of the zone delimited by the fixed and movable chassis elements.

主权项

1. A tilting device for tilting a grass cutting machine to one side, comprising:
a fixed chassis element, designed to rest on the ground, which supports an axle; a movable chassis element comprising an elongated frame having a longitudinal axis extending perpendicularly to the axle and configured to accommodate at least one wheel of the machine having an axis of rotation perpendicular to the axle of the fixed chassis element, wherein the movable chassis element is rotatable about the axle supported by the fixed chassis element, between a retracted position, in which the frame of the movable chassis element extends essentially in a plane formed by the fixed chassis element, and at least one raised position in which the frame of the movable chassis element is separated from the fixed chassis element, wherein the axle remains at a same location on the fixed chassis element when the movable chassis element is moved between the retracted position and the at least one raised position; and a cylinder in a vertical symmetry plane of the device along the longitudinal axis of the frame, and having a body that is attached permanently to the fixed chassis element and a shaft that is movable relative to said body, attached permanently to the frame, and mounted in such manner that in the raised position the shaft extends essentially outside of a zone delimited by the fixed and movable chassis elements.
