Abstract:
1. A seed firming assembly for agricultural seeders, comprising: a seed-firming wheel for firming seeds into soil at the bottom of a furrow created by a furrow opener; and an attaching arm that rotatably supports said seed-firming wheel in said furrow behind the furrow opener; said attaching arm having a forward portion on which the seed-firming wheel is rotatably supported, said attaching arm being pivotally attached to a planter subframe for pivotal movement about an axis of rotation located behind the seed-firming wheel so as to push the seed-firming wheel to roll along the bottom of the furrow in a forward direction during operation while allowing the forward portion of the attaching arm and the wheel to move vertically relative to the planter subframe about said axis of rotation in response to variations in furrow depth and undulating terrain.
