Patent number: 8353149Abstract: A self-propelled forage harvester is provided having a frame, a chopping drum, an accelerator arranged downstream of the chopping drum and a channel between the chopping drum and the accelerator. The channel has a section in which a conditioning unit or a hollow shell can be selectively inserted. The conditioning unit and the hollow shell are jointly supported on a pivot arm pivotable by way of a displacement drive about a pivot axis running horizontally and transverse to the forward direction. The conditioning unit is mounted on the pivot arm rotatably about an axis parallel to the pivot axis. The conditioning unit cooperates with the frame by way of a positive guide, which has the effect that the conditioning unit rotates about the axis in the same direction as the pivot arm.Type: GrantFiled: February 10, 2011Date of Patent: January 15, 2013Assignee: Deere & CompanyInventor: Manfred Engel

Patent number: 7708221Abstract: A kernel processing assembly includes a first roll supported in bearings on a first frame element and a second roll supported in bearings on a second frame element, that forms a slot with the first roll through which harvested crop can be conducted. A rotary bearing is arranged on the first side of the slot that retains the first frame element and the second frame element free to pivot against each other. A pre-load arrangement is arranged on the second side of the slot that pre-loads the first frame element and the second frame element against each other. The rotary bearing includes a shaft to which an eccentric is fastened that retains the first frame element free to pivot, and that the shaft is supported in bearings, free to rotate, relative to the second frame element, so that the width of the slot can be varied by rotating the shaft about its longitudinal axis.Type: GrantFiled: February 26, 2009Date of Patent: May 4, 2010Assignee: Deere & CompanyInventor: Manfred Engel

Patent number: 7311448Abstract: A bearing arrangement for a harvesting machine, including a bearing configured to couple a rotatable shaft with a chassis of the harvesting machine, a first element coupled with the shaft so as to be rotatable therewith, and a second element coupled with the chassis of the harvesting machine. Additionally, at least a portion of the second element is substantially concentrically enclosed by the first element and the first and second elements cooperate to define a contactless seal configured to substantially prevent contamination of the bearing. The shaft is coupled with a product treating element, such as a crop feeding and/or processing element that is driven or idle rotating.Type: GrantFiled: October 19, 2005Date of Patent: December 25, 2007Assignee: Deere & CompanyInventors: Manfred Engel, Joseph A.

Patent number: 7222804Abstract: The invention concerns an arrangement for the adjustment of the position of a shearbar with respect to knives of a chopper assembly. The arrangement includes a first adjusting drive to position the first end of the shearbar at a predetermined first spacing from the knives and a second adjusting drive to position the second end of the shearbar with respect to the knives until a spacing measurement arrangement indicates that the spacing between the shearbar and the knives is less than a threshold value. An analogous procedure is applied to the first adjusting drive. On the basis of the measurement values the shearbar is brought into a position that corresponds to a desired gap between the shearbar and the knives. Each of the first spacing and the second spacing are greater than the desired gap between the shearbar and the knives.Type: GrantFiled: March 29, 2005Date of Patent: May 29, 2007Assignee: Deere & CompanyInventors: Helmut Wolf, Steffen Clauss, Manfred Engel

Patent number: 6449936Abstract: A wide pick-up of a large round baler is mounted for floating or pivoting vertically about the axis of rotation of a rotary secondary conveyor that includes a pair of centering augers at its opposite ends. Provided at each side of the pick-up is a float spring assembly including a coil tension spring and an L-shaped link. Each coil tension spring has its upper end coupled to the baler main frame by a bracket receiving a rod joined to a spring end retainer, and has its lower end defined by a hook which is received in a hole provided in an upper end of the L-shaped link. The lower end of the link is defined by a short leg which projects forwardly beneath lower rear structure of the pick-up frame and contains a kidney-shaped aperture in which a cylindrical coupler is received, the coupler being fixed to a side member of the pick-up frame.Type: GrantFiled: June 15, 2000Date of Patent: September 17, 2002Assignee: Deere & CompanyInventors: Henry Dennis Anstey, Daniel Eric Derscheid, Roger William Frimml, Manfred Engel

Patent number: 6370856Abstract: A large round baler includes a wide pick-up which lifts crop from the ground and transfers it to a rotary conveyor including crop centering augers which narrow the crop flow to the width of the baling chamber before it passes through the chamber inlet. The augers are each equipped with crop lifters and associated with each auger is an auger pan structure formed in such a way as to include a relief area into which foreign objects engaged by the crop lifters may go before they are ejected by the rotating crop lifters.Type: GrantFiled: June 15, 2000Date of Patent: April 16, 2002Assignee: Deere & CompanyInventor: Manfred Engel
