摘要
A seed firming and furrow closing system for no-till agricultural seeders has a smooth in-furrow firming device that gauges the depth and limits penetration of the closing wheel(s). The firming device is mounted behind a seed furrow opener, and one or more spoked closing wheels are rotatably mounted behind the firming device. Each closing wheel is mounted to a support member for the firming device. An adjustable stop is provided to control the operating depth of the closing wheel relative to the firming device. During operation, the firming device moves along the bottom of the furrow to firm the seeds, and the adjustable stop maintains a selected depth of the closing wheel relative to the firming device and the bottom of the furrow. A swivel assembly allows the firming device and closing wheels to swivel from side-to-side to better track the furrow when planting around a curve.
