Patent number: 11785892Abstract: An attachment system for attaching a crop saving accessory to a cutting header where the cutting header comprises a knife mounted along a lower front edge thereof and a discharge opening in a middle rear portion thereof. The header cuts plants and moves the plants laterally to the discharge opening where the plants move rearward through the discharge opening. The system comprises an accessory engagement mechanism on a rear portion of the crop saving accessory configured to engage a header engagement mechanism mounted on the cutting header. A first end of a tether is attached to the crop saving accessory and a second end of the tether is adapted for attachment to a tether location on the cutting header. The tether is configured such that when the accessory engagement mechanism is disengaged from the header engagement mechanism, the tether prevents the crop saving accessory from moving through the discharge opening.Type: GrantFiled: January 7, 2019Date of Patent: October 17, 2023Inventor: Dave Dietrich

Patent number: 11606906Abstract: A harvest header apparatus for harvesting a first crop in a field while preventing damage to a second later crop planted in the same field. A header table with a knife mounted along a lower front edge thereof has a plurality of crop shields attached to and spaced along the header table at a selected shield spacing, each crop shield extending forward from a rear portion thereof located under the knife to a forward end thereof located forward of the knife. A forward portion of each crop shield slopes upward such that crop plants contacted by the forward portion of each crop shield are pushed downward and pass under the knife without contacting the knife. The shield spacing is selected so the crop shields move along rows of second crop and push the second crop plants down and under the table such that same are not contacted by the knife.Type: GrantFiled: May 29, 2020Date of Patent: March 21, 2023Inventors: Dave Dietrich, Ron Wheeler

Patent number: 9027316Abstract: A corn harvesting header comprises a knife bar extending along a front lower edge of a cutting header, with triangular knife sections attached along the bar and a plurality of guards with guard fingers extending forward. Pointed divider pans extend forward from the header such that a slot is formed between adjacent pans. A mounting bracket extends down from a rear of each pan and is attached to forward end portions of a pair of adjacent guard fingers, leaving rear portions of these guard fingers exposed. The divider pans are attached to alternating pairs of guard fingers such that a pair of bare guard fingers extends forward under and laterally adjacent to edges of each slot. The bottom surface of each seed pan is above the guard fingers an elevated distance that is greater than a spacing distance between the guard fingers. The header cuts the corn rows at angle.Type: GrantFiled: February 27, 2013Date of Patent: May 12, 2015Inventor: Dave Dietrich

Patent number: 8991145Abstract: 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.Type: GrantFiled: November 15, 2011Date of Patent: March 31, 2015Inventor: Dave Dietrich

Patent number: 8572942Abstract: A seed pan apparatus has an elongated seed pan plate with parallel right and left edges, a curved configuration and a pointed front end. An engagement mechanism attaches the plate to a harvester cutting header such that the plate is above two adjacent guard fingers, such that an open slot is defined between the right edge of one plate and the left edge of an adjacent plate and the edges of the slot are in proximity to the outer edges of the guard fingers under the adjacent plates. The point is offset to make one front tapering edge forming the point longer than the other. The inclination, height, and fore and aft position of the seed pan plate can be adjusted.Type: GrantFiled: September 23, 2010Date of Patent: November 5, 2013Inventor: Dave Dietrich

Patent number: 8539744Abstract: 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.Type: GrantFiled: September 22, 2011Date of Patent: September 24, 2013Inventor: Dave Dietrich
