Planter with narrow row spacing capability
First Claim
1. An agricultural planting implement comprising:
- an interplant frame including an elongated bar extending in a lateral direction;
a first gang of planter units mounted to said interplant frame bar and extending in said lateral direction;
a second gang of planter units mounted to said interplant frame bar spaced rearwardly from said first gang of planter units, said second gang of planter units being offset from said first gang of planter units in said lateral direction,each said planter unit comprising a furrow opener and a seed metering unit and at least two of said planter units being positionable relative to each other to provide a drill spacing between said at least two of said planter units; and
wherein said first gang of planter units extend rearwardly to locations between said second gang of planter units whereby said first and second gangs of planter units overlap each other in a front to rear direction.

Abstract
A planting implement is disclosed which is operable for performing both row crop and drill planting operations. The implement includes a front planting structure which is detachably coupled to a rear planting structure. The front planting structure includes a front gang of planter units and the rear planting structure includes first and second gangs of planting units wherein the planting units of each gang include a furrow opener and a seed metering unit. The planter units provide accurate seed depth control as well as singulation and precise positioning of seeds along each row. In addition, the planting implement is formed as a compact structure in a longitudinal direction to ensure that a consistent spacing between planted rows of seeds is provided during use of the implement.
