Abstract
A row unit has a frame with an upper portion and a lower portion. The upper portion has a parallel linkage and the lower portion is coupled to plural gauge wheels. A first sensor is configured to provide an output signal and a controllable device is coupled to the upper portion and configured to provide an adjustable down force. A dampening device is coupled to the upper portion and configured to provide adjustable dampening of the row unit based on the output signal.
Claims15
A row unit, comprising:
- a frame comprising an upper portion and a lower portion, the upper portion comprising a parallel linkage, the lower portion coupled to plural gauge wheels;
- a first sensor configured to provide an output signal, wherein the first sensor comprises an accelerometer;
- a controllable device coupled to the upper portion and configured to provide an adjustable down force;
- and
- a dampening device coupled to the upper portion and configured to provide adjustable dampening of the row unit based on the output signal.

A planter adjustable dampening system, comprising:
- a draw bar;
- a plurality of row units, wherein each of the row units comprises:
- a frame comprising an upper portion and a lower portion, the upper portion comprising a parallel linkage coupled to the draw bar, the lower portion coupled to plural gauge wheels;
- a sensor configured to provide an output signal;
- a controllable device coupled between the draw bar and a lower frame member of the parallel linkage and configured to provide an adjustable down force;
- and
- a dampening device coupled between the draw bar and the lower frame member of the parallel linkage and configured to provide adjustable dampening based on the output signal;
- and
- a controller configured to:
- receive the output signal;
- compare the output signal to a threshold value;
- responsive to the output signal meeting or exceeding the threshold value, signal the dampening device to adjust a dampening rate;
- wherein the threshold value is based on an acceleration or a cylinder position of the controllable device where corresponding seed placement from the row unit is undesired.
