I took one of the bolts from mine earlier this year and adjusted the angle of the blades to nearly straight. You could then pull the disc fast as you wanted with no crabwalking but it wouldn' t cut anything. I am now going to fabricate a system to adjust the discs to whatever angle I want and try to reach a happy medium so it will cut good and walk less. I may add about 50 lbs to each edge first and see what that does for it.
