Abstract: Disclosed herein are various adjustable seed meter embodiments having a first seed disk having first openings defined therein and a second seed disk having second openings defined therein adjacent to the first openings such that the first and second openings are alignable to form adjustable seed cells. Various embodiments have a plate adjustment drive system to rotate the first and second seed disks in relation to each other. Other embodiments relate to methods of automatically adjusting a seed meter during operation of the overall planting system.

Abstract: Disclosed herein are various devices, systems, and methods for protecting open seed trenches form ingress of foreign material, such as plant residue. The preventing foreign material from entering the open seed trench during planting increases crop yield by minimizing delayed germination and late plant emergence. Various implementations of adjustable row cleaners may be used to prevent ingress of foreign material. Also, various shields may be disposed on the row units of a planter to prevent ingress of foreign material.

Abstract: The disclosed apparatus, systems and methods relate to devices, systems and methods for on-the-go monitoring and controlled feedback in a supplemental downforce application. Certain implementations provide real-time monitoring of furrow depth via contact and non-contact approaches, some of which are combined with gauge wheel feedback to calibrate and otherwise control the application of supplemental downforce to the row unit. A combination of sensor types are employed in collecting furrow depth measurements, which can be used to adjust the supplemental downforce through a control system module. A gauge wheel load sensor may be used to modify the application of supplemental downforce.
