Publication number: 20070111766Abstract: A spreader, connected to the rear end of a combine harvester, is disclosed for spreading the crop residues existing from a cutter incorporated in the combine harvester behind the spreader across a width that considerably exceeds the width of the combine harvester and the spreader. The spreader includes several spreader wigs pivotally mounted thereon to define the desired spreading width. A wind deflector is mounted on said spreader and upon movement of the spreader in the direction of travel it prevents headwinds and/or lateral winds from affecting the distribution of the crop residues across the spreading width.Type: ApplicationFiled: May 21, 2004Publication date: May 17, 2007Inventor: Bengt Holmen

Patent number: 6881145Abstract: A combine harvester has a husk discharge device mounted downstream from a sieving unit, and a blower mounted in a housing having at least one husk discharge opening, and a straw chopping device, which is located downstream from a straw shaking device and the husk discharge device and which has a rotary cutter mounted in a housing to chop the straw, the housing having an inlet for the unchopped straw and an outlet for the chopped straw. A guide means is located upstream of the straw chopping device, the guide means being displaceable between a first position for closing the inlet so as to effect bypassing of the straw chopping device and allowing deposition of the unchopped straw in the form of strings, and a second position in which is exposed the inlet to allow chopping of straw. A spreading device for spreading of the chopped straw received from the straw chopping device is connected to the outlet thereof and is formed with spreader wings.Type: GrantFiled: October 22, 2001Date of Patent: April 19, 2005Assignee: Rekordverken Sweden ABInventor: Bengt Holmen
