Description
English: A checkwire spool on an old John Deere corn planter; photo taken at the Froelich Gasoline Tractor Engine Museum, Froelich, Clayton County, Iowa, USA. – "I hope my explanation will make sense. Checkwire: this spool holds some half-mile of hook-linked, segmented wire. First the length of wire was unreeled across a planting field. As the tractor (or team) pulled along with this device behind, the wire's length fed through a simple (but ingenious) tongued mechanism along its side. The links between segments triggered the corn planter to feed a few corn seeds to the ground. Rearward tires, not visible here, rolled across the seeds to firm them into the soil. Since the links along this length of checkwire were equidistant, the resulting cornrows were as neat as today's fields. An old timer told me how by using this method a clever farmer could 'cross-hatch' the planting pattern: he would stagger another series of seed lines at right angles to these first rows. The result would be a pegboard square-patterned, or crosshatched pattern for maximum land yield."
