The mower (1) has a cutting mechanism (2), a hitching system (3), and a carrier beam (5) which is connected to the cutting mechanism by a first articulated joint (9) and to the hitching system by a second joint (10). It also has a third articulated joint and a safety mechanism (16). The safety mechanism incorporates a pivoted element (17) connected to the hitching system (3) by a fourth articulated joint (18), and an arm (19) fitted between the pivoted element and the cutting mechanism or the carrier beam. An energy accumulator (21) is connected to the pivoted element by a coupling (22) which, when the cutting mechanism is pivoted to the rear at a certain angle, reduces the length of the lever with which the energy accumulator is applied to the pivoted element. <IMAGE> |
