INNOVATING STRIP-TILL: Unverferth has been building strip-till tools since the early 1990s. But as farming has changed, so have the needs of farmers using the practice. Enter the Raptor Strip-till Tool. The company has pulled together a range of innovations designed to prepare a strip for planting while preserving organic matter in the soil. Using TerrainPro row units with independent depth control to follow soil terrain, the tool preps a seedbed in six stages:
1. The leading swivel coulter with 20-inch blades features 1,500 pounds of down pressure to cut through residues.
2. The free-floating row cleaners with curved-finger design help clear residue from the strip.
3. The centrally mounted, crowfoot-style wheel maintains row depth independently from row to row.
4. The tillage shank precisely tills the soil from 6 to 12-inches deep to manage root-zone hardpan. Model 2030 features spring-cushioned auto-reset shanks with 2,000 pounds of point-load pressure. Model 2015 offers shear-bolt protected shanks with 5,000 pounds of shear pressure.
5. To create the seedbed, 18-inch notched concave closing coulters are mounted on each side of the shank to keep soil in the strip.
6. Standard trailing, crowfoot-style conditioning wheels break up clods and condition the strip. The self-cleaning design prevents plugging with rocks, mud or other debris.
Raptor Strip-Till tools are available in pull-type 12- or 16-row models with 30-inch spacings; or three-point mounted units in 6-, 8- and 12-row models, with 30-, 36- or 38- row spacings.
