摘要：
An agricultural planter (10) includes systems, methods, and apparatus for providing down force pressure at row units (34, 40) of the planter (10). The row units (34, 40) include an electric linear actuator (49) connected to linkages of the row units (34, 40) to provide and maintain a down force pressure for the row unit (34, 40). The linkage (42) may also be removed and replaced with a strut (73) or like mechanism to apply a direct down force pressure to components of the row unit (34, 40). One or more sensors (62) can be included to obtain information related to the ground to automatically adjust the amount of down force provided based upon a ground characteristic in order to maintain a substantially uniform furrow depth.
