Decisive modifications are proposed to a cutting system reducing cutting losses and having a floating disk, in order to improve the efficiency of the system. The lower finger (1) cuts at the lower level and has a tip pointing upwards to prevent the finger from entering the ground； weeds passing past the lower finger pass over the upper finger (3), the accumulation of branches between the fingers being thus prevented. The upper finger (3) has a guard (4) that prevents grains from dropping out of the cutting platform, and the guard is also used to mount two bearings which act to orient the cutter bar (2).
