Patent number: 10091927Abstract: A seed firmer for pressing seeds into soil during planting. The seed firmer includes a mount for attachment to a row unit of a planting machine. An arm defines a ground-facing surface having at least one point of contact with the ground, including a rearmost ground contact point with respect to a direction of forward travel during planting operation. The ground-facing surface has a transition section directly trailing a rearmost ground contact point, the transition section can extending upwardly from the rearmost ground contact point with a radius no less than 25 mm.Type: GrantFiled: December 8, 2017Date of Patent: October 9, 2018Assignee: DEERE & COMPANYInventors: Elijah B. Garner, Jacob D. Salowitz, Kamalakannan Natarajan, Mark Underwood, Drew Whitcomb, Charles T. Graham, Dnyanesh Dhobale

Patent number: 9883626Abstract: A variable is sensed that is indicative of a performance of a machine. A rate of change of the sensed variable is determined, and a control signal is generated for controlling an agricultural vehicle, based upon the rate of change in the value of the sensed variable.Type: GrantFiled: October 2, 2015Date of Patent: February 6, 2018Assignee: Deere & CompanyInventors: Brianna L. Heim, Charles T. Graham, James R. Peterson, Donald Landphair, James Z. Liu

The ground-facing surface has a transition section directly trailing a rearmost ground contact point, the transition section can extending upwardly from the rearmost ground contact point with a radius no less than 25 mm. Also, in some constructions the rearmost section of the ground-facing surface defines a ratio of horizontal distance to vertical height that is no less than 1.2:1.Type: GrantFiled: September 30, 2015Date of Patent: December 12, 2017Assignee: DEERE & COMPANYInventors: Elijah B.

Patent number: 9179594Abstract: A seeding machine, such as a row crop planter, is adapted to switch between two or more seed varieties as the machine traverses a field. The control system uses a programmed quantity of seed representing a number of seeds in the seed meter that need to be substantially consumed once the flow of a first seed variety is stopped before introducing a second seed variety to minimize seed mixing. The seed quantity can be determined by a calibration process or published from the manufacturer or third parties. The seed quantity can also be part of a seeding prescription that includes assignment of where each seed variety is to be planted in a field. The seed quantity and the distance traveled to empty the meter can be used to optimize the planting operation including the machine direction which can also be part of the prescription.Type: GrantFiled: December 14, 2012Date of Patent: November 10, 2015Assignee: DEERE & COMPANYInventor: Charles T.
