ABSTRACT:
A mower includes a cutting mechanism, an attachment structure, a carrying beam connected to the cutting mechanism by way of a first articulation and to the attachment structure by way of a second articulation and a third articulation, and a safety device including an energy accumulator. The safety device includes a pivoting member connected to the attachment structure by way of a fourth articulation and a connecting rod installed between the pivoting member and the cutting mechanism or the carrying beam. The energy accumulator is connected to the pivoting member by way of a connection which is capable, from a certain angle of pivoting of the cutting mechanism toward the rear, about the axis of the third articulation, of reducing the lever arm with which the energy accumulator acts on the pivoting member.
