Abstract: A crop header adjustment system including a plurality of row units, a plurality of dividers disposed between the row units, a plurality of pitch adjustment mechanisms operatively engaged with each of the plurality of dividers, and a controller in communication with the each of the plurality of pitch adjustment mechanisms. The controller configured to adjust the pitch of the plurality of the dividers on-the-go in response to changing conditions.

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.
