| 056500000 | STALK CHOPPERS | 7 |
| 20120174554 | Conveyor, Particularly for a Machine for Mowing Stalk-like Crops - A conveyor ( | 07-12-2012 |
| 20090107103 | Methods and Apparatus for Stripping Leaves from a Stalk Cured Tobacco Plant - A machine which provides for both leaf stripping and grading can be used to process plants, such as burley tobacco plants, by continuously moving the plants in a first direction while simultaneously varying the position of the plants in a second direction relative to a defoliating apparatus. The plants may be moved horizontally through a machine by a transporter engaging the plant stalks while the vertical distance between the transporter (and thus the plants) is varied relative to the defoliating apparatus. The transporter and defoliating apparatus may be positioned at an angle to one another. Due to the changing amount of vertical distance, leaves from different sections of the plants, such as leaves at different stalk heights, can be contacted and removed at different corresponding horizontal locations in the machine. Accordingly, leaves can be graded based on the location(s) from which they are retrieved after removal. | 04-30-2009 |
| 20130111871 | Sugar Cane Chopper Blade - Sugar cane stalks are conveyed along a path passing between upper and lower chopper drums equipped with chopper blades extending lengthwise of the drums and located so that blades of one drum intermesh with those of the other so as to cut the cane stalks into billets. The cutting diameter of the blades of the upper chopper drum is greater than that of the blades carried by the lower blade resulting in the peripheral speed of the upper chopper drum being greater than that of the lower chopper drum. The cutting edge of each of the blades is defined at one side by a compound bevel with the blades being disposed on the drums so that they overlap and mesh bevel-to-bevel. The compound bevels are chosen so as to both satisfy the requirement that the blades be self-sharpening and have close to a zero timing angle. | 05-09-2013 |

| 20120031066 | CHOPPING CORN STALKS AND LIKE CROP RESIDUE - A method of lifting corn stalks from a field surface and chopping the corn stalks with a rotary mower comprises configuring blades of the blade assembly such that as the blade assembly rotates, air is drawn upward under the mower deck; configuring the rotary mower such that an area of a circle defined by a circular path of outer tips of blades of the blade assembly is greater than 60 square feet; and rotating the blade assembly such that the outer tips of the blades move at a speed greater than 20,000 feet per minute and such that the air drawn upward under the mower deck draws corn stalks up from the field surface into contact with the blades. | 02-09-2012 |

| 20080245047 | Shredder head, and mobile silvicultural vehicle including the same - A shredder head for passing over a terrain containing vegetation and rocks so as to silviculturally process said terrain. The shredder head includes an elongated support shaft, a rotor, and a plurality of first and second sections provided longitudinally along a peripheral support surface area of the rotor. The second sections are each disposed between pairs of first sections so as to have an alternation of first and second sections longitudinally along the rotor. Each section includes at least one supporting element for supporting at least one processing tool configured for cooperating with the terrain via a rotation of the rotor for processing the terrain and corresponding vegetation and rocks present therein. First longitudinal gaps are defined between pairs of adjacent first sections, and second longitudinal gaps are defined between pairs of adjacent second sections, and the supporting elements and corresponding processing tools of these sections are shaped, positioned and sized within their respective sections so that the longitudinal gaps are smaller than longitudinal thicknesses of the corresponding processing tools so that rocks present in the terrain to be processed by the shredder head are impacted either by processing tools of adjacent sections or by processing tools of a same given section, so as to decrease average impact forces of the rocks per processing tool of the shredder head. The shredder head is also advantageous in that it is configured to be able to change the nature of the processing tools used therewith, without having to change the rotor or the corresponding supports of the processing tools. | 10-09-2008 |
| 20100011736 | Agricultural Machine, Especially A Field Chopper - An agricultural machine, especially a field chopper, has a carrier vehicle ( | 01-21-2010 |
| 20110258979 | Cotton Stalk Removal Apparatus - A cotton stalk remover apparatus is provided for attachment to a cotton harvesting machine. The removal apparatus is placed in-line behind each harvesting head or operated as a separate machine. The removal apparatus includes a blade section having a rotating blade that lifts and damages cotton stalks. The cotton stalks are released rearward from the blade section assisted by the rotating blade. The blade may have four peripheral blades, and the blade may be assisted in ejecting the cotton stalks by an directional device section having a rotating walker or alternatively a spiral auger that moves the top section of cotton stalks downward and rearward. The lifting and de-rooting of the cotton stalks by the blade may be assisted by a pulling section that includes rotating spindles with spiral flanges that grab, lift and release the stalks immediately prior to the stalks entering the blade section. | 10-27-2011 |
