Abstract: A soil-working farm machine including a frame 1 provided with a device 20 for hitching to a tractor vehicle. At least one row 6, 7 of two bars 2, 3, or 4, 5 equipped with soil-working tools 21 and having a phase opposition movement is connected to said frame by a plurality of oscillating arms 9, 10, 11, 12. The phase opposition movement is generated by a mechanism for transformation of the rotary movement received from a driving source into a reciprocating movement crosswise to the forward direction. The mechanism includes a connecting rod-eccentric device 22 supported by the frame 1. The connecting rod 30, 31, 32, 33 serve to transmit the reciprocating movement to corresponding bars 2, 3, 4, 5.

Abstract: A machine for removing blocks of forage from inside a horizontal silo has a chassis with prongs fitted on a lower part of the chassis and extending substantially horizontally, an arm located at a certain distance above the prongs and bearing a cutting device, wherein the arm with the cutting device is hingedly mounted on a crank by means of a substantially vertical first axle, and the crank is hingedly connected to the chassis by a second axle which is offset relative to the first axle.
