Abstract
A gardening vehicle, more particularly a lawn-mower, comprising two sections and a composite duct across them: a first section, which comprises a front axle, a driver's scat and a couplings for a tool; and a second section, which comprises an engine with a corresponding transmission, a rear axle and a dump box; the first and the second section, together with the duct elements, being mutually articulated about a common vertical axis so as to perform a steering action.
Claims21
A gardening vehicle comprising:
- a first section including:
- a front chassis,
- a front wheels axle supported by said front chassis,
- a driver's seat mounted on said front chassis,
- a tool supported by said front chassis;
- a second section including:
- a rear chassis,
- an engine mounted on said rear chassis,
- a transmission connected to said engine,
- a rear wheels axle supported by said rear chassis,
- a dump box mounted on said rear chassis;
- an articulation between said first section and second section, said articulation being articulated about a vertical axis so as to produce a steering action,
- a hollow body fixed to said rear chassis,
- a sleeve contained in said hollow body so that said sleeve is rotatable,
- a kinematic transmission system supported by said sleeve, so tat said sleeve and said kinematic transmission system arc free to roll, within specific limits, with respect to the vehicle.
