What the Max-Chisel is used for
Max-Chisel combines residue cutting and mixing by the front disks with deeper loosening from its chisel shanks. It is used after harvest where moderate primary tillage and residue incorporation are desired in one pass. The rear finishing system levels ridges and helps prepare the field for later finishing or planting.
Why the Great Plains Max-Chisel stands out
The disk-and-chisel arrangement combines surface residue management with deeper soil fracturing. Shank protection and replaceable points are intended to handle variable field conditions. A rear basket, reel, or comparable attachment improves surface leveling.
Buying a used Great Plains Max-Chisel
Examine shanks, reset assemblies, points, and shank mounts for fatigue, cracks, and repaired welds. Inspect disk gangs for worn blades, noisy bearings, and loose hardware, and check rear finishing equipment for damaged bars or bearings. Test depth, lift, and fold hydraulics, then inspect tires and wheel hubs.
