Abstract
A furrow closing system for an agricultural seed planter provides soil closing and soil pressing that are controlled by independent adjustable down force or pressure systems that react to a common frame element or backbone. The adjustable down force systems may be manually controlled, electronically controlled and/or part of a closed loop system. A down stop, which may also be adjustable, may be used to limit the maximum force of the adjustable down pressure systems.
