Abstract
A lawn mower comprising: a frame (10); wheels and motors (20a;20b) for moving the frame (10) relative to a work surface (L); one or more blades (30) for cutting the grass on the work surface (L); a plurality of sensors (S1, S2) for generating detection signals (SR) representative of a distance of a mass (M) relative to the frame (10); a control unit (40) for determining, as a function of the detection signals (SR), whether the mass (M) is at a distance from the frame (10) within a predetermined value range, and to adjust the operating conditions of the lawn mower (1) as a function of the detection signals (SR); a selection circuit (50) interposed between the control unit (40) and sensors (S1, S2) for selectively enabling a connection between each of the sensors (S1, S2) and an input of the control unit (40).
Claims16
A lawn mower comprising:
- a frame (10);
- actuating means (20) for moving said frame (10) relative to a work surface (L);
- one or more blades (30) mounted on said frame (10) for cutting the grass present on said work surface (L);
- a plurality of sensors (S1, S2) for generating detection signals (SR) representative of a distance of a mass (M) relative to said frame (10);
- wherein said plurality of sensors comprises a first series of sensors (S1) adapted to detect the presence of grass on said work surface (L);
- a control unit (40) adapted to determine, as a function of said detection signals (SR), whether said mass is at a distance from said frame (10) which is included within a predetermined value range, and to adjust operating conditions of said lawn mower (1) as a function of said detection signals (SR);
- a selection circuit (50) interposed in a circuit between said control unit (40) and sensors (S1, S2) and suitable to selectively enable a connection between each of said sensors (S1, S2) and an input of said control unit (40)
- wherein, said selection circuit (50) is interlocked with said control unit (40) in such a way to regulate at least the operating conditions of:
- activation/deactivation of the actuating means (20) depending on the presence of grass on the work surface (L);
- activation/deactivation of the blades (30) depending on the presence of grass on the work surface (L).
