Aggressive Primary Tillage Tool

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" of soil, chopping it to accelerate decomposition.

Mounted to individual C-shanks, 24" blades on 15" 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" 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', and four folding models from 16' 6" to 24'. All feature hydraulically-adjustable disc gang depth control and heavy-duty toggle-trip reset shanks that can till up to 12" deep. With 2,450 pounds of horizontal trip force, these shanks will not pull out of hard ground like a traditional chisel. Medium-duty chisel shanks are also available.

Features May Include:

Implement Command® (Optional)

• Take control of your adjustment and monitoring needs right at your fingertips with the Implement Command option. This system allows you to set, adjust, and monitor your implement on-the-go and in real time – on your ISOBUS-compatible monitor in your tractor cab.

Choose Parabolic or Chisel Shanks

• Order the Max-Chisel the way you want it with two different shank combinations: standard chisel (right) or heavy-duty parabolic toggle-trip shanks (left). When equipped with heavy-duty parabolic toggle-trip shanks, this unit works in the mid-ranges of 8" to 12" – requiring less horsepower than competitive disk rippers that run in the 13" to 15" range – while horizontally fracturing soil much better than a disk chisel. Toggle-trip shanks either run at the set depth or trip – there is no in-between. Both shanks are effective at eliminating ruts and shallow compaction caused by harvest traffic.

Exclusive Concave Turbo-Wave Blades with Patented “Samurai Edge”

• Two opposing rows of exclusive 24" concave Turbo-wave blades aggressively remove root balls while mixing and incorporating crop residue into the top 4" to 5" of soil. This anchors the residue to the ground to accelerate the decomposition process.

INDIVIDUAL DISC MOUNTS

• Mounted to individual C-shanks, 24" blades on 15" spacing offer adequate room to clear the flow of trash/residue. They are also designed to perform well in wet conditions.

Maintenance-Free Bearings

• All blades feature maintenance-free tapered bearings in a cast hub with six-lip interlocking seals to keep grease in and dirt out.

Single-Point Depth Stop

• Adjust the depth across the entire width of the machine in one convenient location.

Walking Tandem Axles

• Maintain consistent mainframe height for accurate, uniform tillage depth.

Optional Angled Rear Chopper Wheels

• Patented angled chopper wheels and 15" shank spacing work together to pull dirt back into shank voids, leveling soil while maintaining the vertically-tilled profile left by the shanks.

Optional Chopper Wheel with ML Roller

• Choose chopper wheels w/ ML rollers for a smooth, uniform finish.

Rear Hitch Options

• Variety of hitch configurations in long, short, ball, and flex-tongue configurations are available. The rear hitches complement the versatility of the Max-Chisel by enabling cover crop, nutrient application, and other light-duty towed attachments.
