Patent number: 11712004Abstract: A follower assembly of a cam assembly for a harvester reel including a baffle, a compressible member adjacent the baffle, and a roller spacer adjacent the compressible member. The follower assembly further includes a tubular cam follower housing the roller spacer, and a fastener extending through the tubular cam follower, the roller spacer, the compressible member and the baffle. The resultant follower assembly provides a construction which minimizes peening of the baffle, whereby the fastener maintains its clamp load such that the cam followers maintain engagement with the cam track and the potential for breakage of the fastener is minimized.Type: GrantFiled: March 2, 2020Date of Patent: August 1, 2023Assignee: CNH Industrial America LLCInventor: Barry E. Lehman

Publication number: 20230034156Abstract: An actuator assembly for moving an implement attached to an agricultural vehicle. The actuator assembly includes an actuator comprising a longitudinal axis, a cylinder extending along the longitudinal axis, and a piston rod extending from the cylinder along the longitudinal axis and that is configured to be attached to the implement at a connection point. A safety stop is pivotably attached at the connection point and is movable between a deployed position where the safety stop is configured to block retraction of the actuator, and a retracted position where the safety stop is not configured to block retraction of the actuator. The safety stop is configured to rotate with respect to the actuator about a first rotational axis that is orthogonal to the longitudinal axis, as well as a second rotational axis that is orthogonal to both the longitudinal axis and the first rotational axis.Type: ApplicationFiled: July 29, 2021Publication date: February 2, 2023Applicant: CNH Industrial America LLCInventors: Seth Bietz, Jonathan E.

Patent number: 7455584Abstract: A system and method for positively discharging crop residue from a combine for precisely and consistently delivering crop residue from the threshing and separating area of a combine to the combine's residue handling system or outwardly from the rear of the combine and onto the harvested field below as a windrow. The present invention can include, or operate in cooperation with, a discharge mechanism, such as a conventional discharge beater, which delivers at least some of the crop residue to a conveying mechanism of the system. The system also includes a guide mechanism including a door arrangement configurable in several alternative configurations for receiving and merging and regulating crop residue flow from the discharge mechanism and the conveying mechanism, and directing the merged flow to a desired processing mechanism, such as, but not limited to, a chaff spreader, a straw chopper and/or spreader, etc.Type: GrantFiled: March 14, 2006Date of Patent: November 25, 2008Assignee: CNH America LLCInventors: Herbert M.

Patent number: 7392123Abstract: A system and method for detecting existence of a failed or broken shear bolt supporting all or a portion of a concave of a threshing system of an agricultural combine and utilizing information relating to rates of movement and absence of movement of a concave to determine the existence and non-existence of a failed or broken shear bolt supporting the concave. More particularly, the present system and method is operable to diagnose existence of a broken shear bolt from a rapid downward movement of the concave and non-movement of the concave during operation of a driver for repositioning the concave. Also, existence of a false broken concave condition can be diagnosed by movements of the concave responsive to operation of the driver.Type: GrantFiled: November 1, 2004Date of Patent: June 24, 2008Assignee: CNH America LLCInventors: David N. Heinsey, Barry E. Lehman

Patent number: 7022013Abstract: An axial flow combine harvester comprises a rotor having a separator section which can be adapted to suit different crops. Within the separator section staggered crop engaging elements are spaced from one another along a first helical crop flow path. The crop flow path can be modified to suit crops such as corn and sunflowers by attaching at least one separator blade to the rotor in place of or in addition to selected crop engaging elements of the rotor. The separator blade forms a continuous crop engaging surface defining a second helical crop flow path of greater pitch than the first path defined by the staggered strop engaging elements.Type: GrantFiled: November 17, 2004Date of Patent: April 4, 2006Assignee: CNH America LLCInventors: Eric P.

Patent number: 6485364Abstract: A combine harvester comprises a threshing and separating arrangement mounted to a main firm and including a generally cylindrical chamber having a generally longitudinal axis. Part of the chamber is constituted by a separating concave assembly comprising at least two separating concaves, the one located behind the other. The concaves are taken from a choice of less and more aggressive separating concaves. The chamber comprises mounting device operable to receive and hold each of the separating concaves. The front and/or the rear concaves can be removed and replaced.Type: GrantFiled: June 11, 2001Date of Patent: November 26, 2002Assignee: New Holland North America, Inc.Inventors: José G. T.

Patent number: 5941056Abstract: A disc mower incorporates a modular disc cutterbar. The drive mechanism for the mower utilizes a V-belt drive apparatus that requires proper tensioning which is accomplished through a spring tensioning mechanism that includes an indicator to visually determine when the proper tension has been applied. The indicator includes a bracket positioned adjacent the spring and has a length substantially equal to the length of the spring required for exerting the proper spring force for tensioning the drive belt.Type: GrantFiled: May 7, 1998Date of Patent: August 24, 1999Assignee: New Holland North America, Inc.Inventor: Barry E.

Patent number: 5919087Abstract: The disclosure relates to a concave latch mechanism for an agricultural combine. The invention consists of concave surrounding a rotor. The concave has a concave pin and an adjust pin. The adjust pin is inserted into a support slot located in the frame. The concave pin is inserted into a handle also located on the frame. The handle has a lever which orients a curved cradle plate which supports the concave pin. When the lever is released, the cradle plate correctly orients the concave pin with the handle. The concave pin enters the cradle plate through an aperture. The aperture can have a sloped lead-in which assists in the positioning of the concave pin. The handle can also have an isolation mount between a portion of the handle and the frame. This isolation mount helps minimize vibrational noise from the rotor.Type: GrantFiled: November 6, 1997Date of Patent: July 6, 1999Assignee: New Holland North America, Inc.Inventors: Russell W. Strong, Barry E. Lehman, Floyd W. Grove, Eric Cromheecke

Patent number: 5806291Abstract: A pull-type mower conditioner includes a crop harvesting header vertically movable relative to the frame of the mower conditioner between a raised transport position and a lowered operative position, a lift mechanism to effect the movement of the crop harvesting header relative to the frame, and a transport latch mechanism to control the locking of the lift mechanism in the transport position. The transport latch mechanism has a biasing lever operably positionable between locking and unlocking positions. An extension spring is connected to the biasing lever to bias the lever in the selectable positions. The transport latch will not engage whenever the header is moved to the transport position to avoid an obstacle unless the biasing lever is moved to the lock position.Type: GrantFiled: June 25, 1996Date of Patent: September 15, 1998Assignee: New Holland North America, Inc.Inventors: Barry E. Lehman, Michael L. Bandi, Galen R. Erb
