Martin - Model 13 - Spading Closing Wheel Systems
Martin Spading Closing wheels move soil toward the seed at planting depth, while lifting and fracturing the surface layer to achieve compaction free closing of the seed trench in wet, hard, or sod conditions. With soil firmed around the seed from each side and the surface layer loosened, crops emerge sooner and planting can be done at the proper depth, even in wetter conditions, without fear of crushed soil above the seed preventing emergence.
Our Spading Closing Wheels do not attempt to close the seed trench by a crushing action from the top down. The soil is wedged toward the seed from either side at seeding depth by a pair of Martin Row Cleaner wheels. The ends of the teeth have full bevels cut on them. The beveled sides of the teeth on each wheel are placed toward the row and the narrow edge enters the soil first producing a wedging action. As the teeth on the wheels rotate up out of the soil, a slight lifting and crumbling occurs in the surface layer. The area on either side of the seed and immediately above it is not fractured. Because of the shape and spacing of the teeth on these wheels, wet soil does not bind to them
