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.

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; anda 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. 2. The tilting device as recited in claim 1, wherein the movable chassis element is configured such that in the retracted position the movable chassis element fits inside the fixed chassis element. 3. The tilting device as recited in claim 2, wherein the axle is mounted essentially above the plane formed by the fixed chassis element. 4. The tilting device as recited in claim 3, wherein the movable chassis element is a right-angled, “L”-shape, the angle of which is truncated. 5. The tilting device as recited in claim 1, wherein the cylinder is permanently attached to the fixed and the movable chassis elements at a point close to the axle. 6. The tilting device as recited in claim 1, further equipped with at least one retractable jack that is permanently attached to the movable chassis element and braced against the fixed chassis element to lock the movable chassis element in at least one of the raised positions. 7. The tilting device as recited in claim 1, wherein the movable chassis element comprises a limit stop extending essentially perpendicularly to said frame. 8. The tilting device as recited in claim 1, wherein the cylinder is operated via a pedal or a lever. 9. The tilting device as recited in claim 1, wherein the cylinder is a single-action cylinder. 10. The tilting device as recited in claim 1, wherein the cylinder belongs to the group consisting of: hydraulic cylinders;pneumatic cylinders;electric cylinders. 11. The tilting device as recited in claim 1, wherein the axle is mounted essentially above the plane formed by the fixed chassis element. 12. The tilting device as recited in claim 11, further equipped with at least one retractable jack that is permanently attached to the movable chassis element and braced against the fixed chassis element to lock the movable chassis element in at least one of the raised positions. 13. The tilting device as recited in claim 11, wherein the cylinder is a single-action cylinder. 14. The tilting device as recited in claim 12, wherein the movable chassis element comprises a limit stop extending essentially perpendicularly to said frame. 15. The tilting device as recited in claim 11, wherein the movable chassis element comprises a limit stop extending essentially perpendicularly to said frame. 16. The tilting device as recited in claim 1, wherein the movable chassis element comprises a limit stop extending essentially perpendicularly to said frame. 17. The tilting device as recited in claim 1, wherein the frame of the movable chassis element is rectangular and has a length and a width, wherein the length is greater than the width and extends perpendicularly to the axle. 18. The tilting device as recited in claim 1, wherein the frame comprises first and second spaced bars extending along the length and connected together by first and second cross bars, forming an open frame cradle arranged to support the at least one wheel between the first and second spaced bars with the axis of rotation being parallel to the bars.
