Soil moisture-based planter downforce control
First Claim
1. A seeding machine comprising:
- a main frame;
a row unit coupled to the main frame, the row unit having a row unit frame, a gauge wheel coupled to the row unit frame, and a furrow opener coupled to the row unit frame; and
a downforce adjustment system for adjusting an amount of downforce applied to the row unit, the downforce adjustment system including a moisture sensor configured to detect a moisture level of soil, a controller configured to receive a signal from the moisture sensor corresponding to the detected moisture level, and an actuator configured to change the amount of downforce applied to the row unit based on the signal received by the controller,wherein the row unit is one of a plurality of row units coupled to the main frame, and wherein each of the row units includes its own associated controller, its own associated moisture sensor, and its own associated actuator, such that each controller only communicates with the moisture sensor and the actuator associated of a single row unit.

Abstract
A seeding machine includes a main frame, and a row unit coupled to the main frame. The row unit has a row unit frame, a gauge wheel coupled to the row unit frame, and a furrow opener coupled to the row unit frame, the furrow opener having a stationary or rotating surface that contacts and moves soil. The row unit also includes a furrow closer, the furrow closer having a stationary or rotating surface that contacts and presses soil. The seeding machine also includes a downforce adjustment system for adjusting an amount of downforce applied to the row unit, the downforce adjustment system including a moisture sensor, a controller configured to receive a signal from the moisture sensor, and an actuator configured to change the amount of downforce applied to the row unit based on the signal received by the controller.
