ABSTRACT:
The present invention is an adjustment mechanism to move the seed firming wheels into its correct side-to-side position. The seed firming wheels are rotatably mounted to a bracket which in turn is mounted to a wheel support member of the planter unit frame. The bracket is provided with two radiused bushings which cooperate with radiused surfaces in the side walls of the wheel support member. The side walls and the wheel support member are provided with fore/aft extending slots through which adjustment bolts pass through the bracket and sidewalls of the wheel support member for clamping the bracket to the wheel support member.
