  • Agricultural machine, particularly of the rotary mower type, comprising an improved chopping device
    Patent number: 7370459
    Abstract: An agricultural machine fitted with a chopping device. The chopping device includes a guard, at least three chopping members disposed above the guard and that are linked thereto to pivot around a shaft directed upwards, and transmission elements that rotate the chopping members around the respective shafts. Among the chopping members at least two adjacent chopping members rotate in opposite directions converging towards the front. The distance separating the rotary shafts of two adjacent chopping members rotating in opposite directions converging towards the front is greater than at least a distance separating the rotary shafts of two adjacent chopping members having directions of rotation that do not converge towards the front. The arrangement of the chopping members in this manner can be used advantageously to improve the removal of the chopped product towards the rear of the chopping device.
