The high performance of the Sunflower Saber Blade™ on the 6631 is exclusive to Sunflower. This unique combination of low concavity, twenty-five correctly sized flutes and the serrated “sawtooth” edge works the soil like no other blade can. Sunflower Saber Blades keep cutting heavy residue long after the competitor’s blades have dulled beyond effectiveness. The front and rear gangs of the 6631 are mounted at an 18-degree gang angle, allowing the narrowly spaced 22-inch blades to mix soil and residue to achieve the desired results. Increase the operating blade depth and move from Spring’s fast, shallow vertical tillage to Fall’s heavy crop residue management. The 6631 SW keeps the wing wheels out to the edge of the wing maintaining the correct relationship with the front and rear gangs, ensuring superb performance and a level field.
