The present invention relates to a device which is to be combined with a bar with disks, that include a plurality of cutting elements with each one turning about its respective axis. The axes of the cutting elements are directed upward during work and are arranged alongside each other along a transversal line with respect to a forward direction of the device during work. Each cutting element is made of a cutting disk including cutting blades connected to the cutting disks and a support which is also provided with blades. Each support is connected to the corresponding cutting disks. The cutting bard and disk of the present invention permit the cutting and chopping and/or crushing of plants or vegetables.

A farm machine includes first and second elements connected to each other through a joint which permits a rotation between the first and second elements. The farm machine also includes a stop member for limiting the rotation between the first and second elements and a protective device for isolating the stop member which is not deformed during the rotation of the first and second elements.

This invention relates to a farm machine with a toolholding frame including a crosswise support provided with at least two rotors which is jointed to a coupling device by way of a pin. The crosswise support is made up of a central part and two lateral parts jointed to the ends of the central part by way of substantially horizontal pins. Each of these lateral parts is provided with a coupling device having three hooking points for connection to a rotor.

An agricultural machine to be pulled by a tractor and having working tools driven by outer driving sources comprises a chassis arranged to support the working tools, a beam unit arranged for connecting the chassis with a tractor and including a first beam and a second beam, a transmission including a first portion and a second portion turnable relative to one another and arranged so that the first portion is connected with the first beam turnable relative to one another about an upward axis of turning of the portions whereas the second portion is fixedly connected with the second beam, a locking element arranged to lock the rotation between the first portion and the first beam, and a driving device arranged in the transmission and including two input shafts located in the first portion and receiving the movement from one driving source, an output shaft located in the second portion and adapted to transmit movement to the working tools at approximately the same speed independently of the input shafts which receives the movement, and intermediate driving element interconnecting the two input shafts and the output shaft, the working position of the input shaft which receives the movement of one outer driving source is determined by the locking element which locks the rotation between the first portion and the first beam.

Agricultural machine

The disclosure is of, in a mower which works over a great cutter width and comprises cutter discs or cutter drums or cutter belt pulleys or other rotary elements involved in the cutting operation, at least one device for reducing the width of the windrows comprising an endless flexible windrowing member which travels around two drums having substantially vertical axes of rotation, the first of said drums being approximately above one of said rotary elements at one extremity of the mower, the second of said drums being spaced to the rear of and nearer to the middle of the mower so that the windrowing member follows a path at an acute angle to the cutting front, at least one of said drums being driven at a speed different from that of said rotary elements so that the windrowing member impels cut fodder from a margin towards the middle of the windrow.
