Claim:
1. An agricultural seed planting implement, comprising: a frame moveable in an up and down direction relative to soil area over which the frame traverses; a seed trench opening assembly mounted to said frame; a pair of gauge wheels, each gauge wheel having an axis, and wherein the axes of the gauge wheels are offset by a first distance in a vertical direction; equal length gauge wheel arms pivotally mounted to said frame for journaling said gauge wheels, the position of the gauge wheels setting the depth of the seed trench, wherein each gauge wheel arm is defined by a center line extending through a center of the respective gauge wheel arm in a horizontal direction substantially orthogonal to the vertical direction, and wherein the center lines of the gauge wheel arms are offset by the first distance in the vertical direction; a depth control device including a control lever settable in a plurality of discrete positions and a control rocker pivotally connected to said control lever for abutting said gauge wheel arms to set the depth of said seed trench; and, wherein said gauge wheel arms are mounted to said frame in staggered locations and said control rocker has arms staggered to matched the staggered locations of the gauge wheel arms.
