Bison Extra Heavy Duty blades are exceptional for a wide range of material handling chores… from landscaping to heavy dam building jobs.An important factor in the performance of the Bison blades is the precision-formed moldboard with the exact curvature needed for maximum penetration. This precision allows Bison blades to cut and roll the soil rather than dragging, which saves time horsepower and fuel. The moldboard can be rotated 360 degrees with forward and reverse working positions.
