Close without surface compaction
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, and because of the shape and spacing of the teeth on these wheels, wet soil does not bind to them.
- Speeds up warming of the row area
- Closing wheel arm pressure can be greatly reduced
- Seed trench is closed in the most severe conditions
- Seed depth does not have to be raised to insure emergence
- Soil above the seed is loose and slightly mounded allowing quicker emergence in a compaction-free environment
- Sidewall compaction is greatly reduced
In the past we thought the only way to grow no-till crops successfully was to wait until the soil was dry enough for the planter’s smooth closing wheels to crumble the soil over the seed. Our long-standing struggle with the problem prompted us to find a solution that we have since patented. Customers around the country are praising it.
