A windrower rake consisting of a comb and a rotor having a special configuration that makes it possible to optimise the windrowing system, avoiding material loss and forage entanglement in the rotating areas of the machine, thereby increasing the performance and efficiency of the machine. The comb contains a plurality of teeth arranged along several horizontal bars which, in turn, are mounted on either side on two rotating disks that rotate about a horizontal shaft. The blade rotor is located above and in front of the comb, including a transverse horizontal shaft to which a plurality of teeth, blades or disks distributed along the length thereof, are rigidly connected, partially covered by a casing.

An agricultural machine comprising a swath sensor system. The swath sensor system is configured to detect one or more properties of a swath on an agricultural area traversed by the agricultural machine. The agricultural machine further comprises a swather for swath generation. At least one sensor of the swath sensor system is configured to detect properties of a stream of swath-forming material during or after its processing into a swath by the swather.

A rake apparatus is disclosed. The rake apparatus includes a plurality of material gathering members connected to a continuous conveyor member such as a chain or a belt. A drive sprocket supports the conveyor member at a discharge end of the rake apparatus. An idler sprocket supports the conveyor member at a distal end of the rake apparatus. The material gathering members contact a bottom stripper guard and a top stripper guard as they travel about the raking device to remove crop material from the material gathering members. The rake apparatus may be part of a harvesting machine in which the processing chamber of the harvesting machine has a width that is the same width as the pickup device of the harvesting machine.
