Abstract
A combination fertilizer and seeding Implement includes a front section of disk type fertilizer openers and a rear section of frame mounted seed openers. The fertilizer openers are connected by drawbars to a rockshaft which is vertically adjustable to accommodate different ranges of operating depths of the frame mounted tools. Shank depth is set by frame height, and the vertical adjustability of the rockshaft facilitates a wide range of frame operating heights for different tool depths while maintaining optimum disk opener drawbar angles.
