Towed field cultivator MAX-CHISEL™

with rollerrigid tinewith hydraulic adjustment

The Great Plains Max-Chisel is an aggressive primary tillage tool that is designed to achieve complete fracture at shallower depths, leaving fields smoother and more uniform than most traditional disk rippers. Built on the same rugged platform as the Great Plains Turbo-Chisel®, the Max-Chisel utilizes two opposing rows of exclusive concave turbo-wave blades. With a patented “samurai edge,” the blades aggressively remove root balls while mixing and incorporating residue in the top 4" to 5" (10-13 cm) of soil, chopping it to accelerate decomposition. Mounted to individual C-shanks, 24" (61 cm) blades on 15" (38 cm) spacing allow plenty of clearance for trash and residue. All feature maintenance-free tapered bearings in a cast hub and a six-lip interlocking seal to keep grease in and dirt out. Max-Chisel works the soil more aggressively than a traditional chisel, but leaves the surface level enough for a single-pass tool, such as Great Plains Disc-O-Vator® or Turbo-Max®, to finish the field ahead of the planter in the spring. Angled chopper wheels combine with 15" (38 cm) shank spacing to pull dirt back into the shank voids, leveling the soil while maintaining the vertically-tilled profile left by the shanks. Max-Chisel is available in two rigid models, ranging from 11' 6" to 14' (3.5-4.3 m), and four folding models from 16' 6" to 24' (5-7.3 m). All feature hydraulically-adjustable disc gang depth control and heavy-duty toggle-trip reset shanks that can till up to 12" (30 cm) deep. With 2,450 pounds (1111 kg) of horizontal trip force, these shanks will not pull out of hard ground like a traditional chisel. Medium-duty chisel shanks are also available.
