Patent number: 11612107Abstract: A chopper arrangement for an agricultural harvester, having a housing and a plurality of rotatable knife rows in the housing. The chopper arrangement includes a counter knife arrangement including a first counter knife bank and a second counter knife bank downstream of the first counter knife bank. The counter knife arrangement is movable between an engaged position, in which the first and second counter knife banks at least partially overlap the plurality of rotatable knife rows, and a disengaged position, in which the first and second counter knife banks are retracted away from the plurality of rotatable knife rows. The counter knife arrangement also includes a mechanical linkage coupling the first counter knife bank to the second counter knife bank to provide for simultaneous movement of the first and second counter knife banks upon actuation of the counter knife arrangement between the engaged and disengaged positions.Type: GrantFiled: May 12, 2022Date of Patent: March 28, 2023Assignee: CNH Industrial America LLCInventors: Frank R.

Patent number: 9986687Abstract: A stone trap assembly including an entrance and an exit. The entrance receives objects from a crop flow path for accumulation into the assembly during a harvesting operation, and the exit allows evacuation of the accumulated foreign objects out of the assembly during an evacuation operation. The assembly further includes a door configured to be rotatable around a first rotation axis, substantially transverse to the crop flow path, for movement along a door movement trajectory between a closed position and an evacuation position, and an impeller for forcing the accumulated foreign objects towards the exit. The impeller is configured to be rotatable around a second rotation axis, substantially transverse to the crop flow path, for movement along an impeller movement trajectory between a retracted position and an extended position closer towards the exit. The door and impeller are separately movable during at least a part of the trajectories.Type: GrantFiled: October 20, 2015Date of Patent: June 5, 2018Assignee: CNH Industrial America LLCInventors: Jolan Heyns, Marijin Vanslambrouck, Gert Mattheeuws, Willem De Coninck
