"Whirlwind" Strips Create Ideal Strip-Till Seedbed
Plastic swirl strips on Dawn Strip-Till closing units create a whirlwind in every row. The whirlwind breaks up dirt particles and mixes them with fertilizer to create a perfect seedbed, says Rodney Arthur, Dawn Equipment, Inc.
"Just as fuel injectors create a vortex to break gas particles up and plunge them into the combustion chamber, our strips create a parabolic vortex that blasts soil particles against each other," he says. "The force pulverizes them, mixing fertilizer particles with them before ejecting them back into the ground. The parabolic swirl creates a bermed bed ideal for the germinating seed."
Also available in steel, the plastic strips are especially well-suited to heavier soils. Dirt and crop residue can build up on the steel strips, interfering with vortex development. However, when the material reaches a critical mass, the plastic strips will bend outward, dislodging it.
The strips mount to the closing wheels on the Dawn Pluribus Strip-Till Unit. Steel strips are priced at $89 per wheel. The ultra high molecular weight plastic strips are priced at $70 per wheel. Dawn's Pluribus Strip-Till Units are priced at $3,250 each.
"The units can be used in heavy residue in the fall or in a spring pass to prepare the soil," says Arthur. "A large share of our customers use them a couple hours ahead of the planter, running at 8 to 10 mph. Walk behind a unit, and the seedbed looks like potting soil."
