MIDDLE BUSTER/SUB SOILER XB KING KUTTER'S MIDDLE BUSTER/SUBSOILER combines strength and durability to offer a tool with many uses. Its tubular steel shank and heavy duty frame construction make a solid platform for the furrower to do its job. The middle buster point is great for laying off rows, digging potatoes, pointing a ditch, general field prep, and many other farm, field, and garden uses. The subsoiler point is for ripping sod and loosening compacted soil for better plant growth and production.
