Supplemental Lifting Fingers Patents (Class 56/312)
  • Patent number: 9642308
    Abstract: A crop lifter apparatus has a bracket for attachment to a header guard finger. A cylindrical groove in a front portion of the mounting bracket has an axis perpendicular to a travel direction and a lock bolt hole is defined through the mounting bracket at the groove. The rear of a finger support member has a cylindrical wall engaged in the groove, and defines a cylindrical lock aperture with an axis coincidental with the axis of the groove. A slot in the rear of the support member is oriented perpendicular to the axis of the lock aperture. A lock cylinder is engaged in the lock aperture and a lock bolt extends through the lock bolt hole and the slot and into the lock cylinder and is tightened to secure the support member to the mounting bracket at a selected finger angle. A length of the lifting finger may be adjustable.

  • Patent number: 8991145
    Abstract: A crop lifter apparatus has a base member adapted to be attached to a cutting header guard finger about a lifter pivot axis. A plurality of lifter tips with different configurations are releasably attachable to the base member at a mounting position such that the attached lifter tip extends forward from the base member. A bias element is operative to exert a bias force on the base member urging a front portion of the base member forward of the lifter pivot axis to pivot downward about the lifter pivot axis, and the bias force urges the base member to bear against a stop. The tips can be configured to suit various conditions of soils and crops.

  • Patent number: 8539744
    Abstract: A crop lifter for attachment to a cutting header includes a lifter member adapted for attachment to the header and a lifting finger attached to the lifter member by a quick-attach mechanism such that a leading end of the lifting finger is ahead of and below the knife. The lifting finger is structurally weak compared to the lifting member such that the lifting finger will readily move when striking an obstruction, thereby preventing damage to the lifter member or header. The crop lifter or similar crop accessory can have a latch member at a rear end thereof, and a cooperating latch member attached to the header. The accessory latches to the header and a releasable latch lock prevents forward movement of the accessory that would disengage the latch.

  • Publication number: 20010037635
    Abstract: A crop lifter is described that combines the lifting ability of a conventional lifter with the sickle protecting qualities of a sickle guard. Crop-lifting surfaces in the combination lifter and guard extend from a forward end of an extended guard finger to a rearward end located substantially above a sickle knife slot and substantially rearward of a leading edge of the knife slot. This arrangement has been found to reduce crop loss. Some versions of the combination lifter and guard include a crop-holding surface that prevents crop loss by preventing grain from spilling backward or off the front end of a cutter bar.
