Abstract: A stalk sensor comprising a first wand comprising a contact surface at a distal end, a first magnet disposed at a distal end of the first wand, a second wand comprising a contact surface at a distal end, and a second magnet disposed at a distal end of the second wand, the magnet configured to attract the first magnet and thereby the first wand into contact with the second wand at the contact surfaces with the second wand, wherein the first contact surface and the second contact surface are in contact when the stalk sensor is in a home position. The stalk sensor wherein the wands are self-aligning on horizontal and vertical axes.

Abstract: The disclosed apparatus, systems and methods relate to automatic calibration systems, methods and devices for use with vehicle systems such as grain cart and combine vehicle systems to calibrate the yield monitor via collected calibration load profile data that is processed and used to calibrate and recalibrate the system automatically.

Abstract: The disclosed apparatus, systems and methods relate to an electrically driven corn head and/or a corn head retrofitted with individual electric motor assemblies on each corn head. In various implementations, the corn head is configured for row-by-row control of harvesting operations. In certain implementations, the corn head and associated systems can count and estimate size of stalks and ears. Further the system is configured to measure yield.
