A C-cushioned middlebreaker cuts out center bulk and leaves level soil profile. Plus, you maintain a consistent depth without wandering. The blade is cushioned to protect against obstacles and never needs adjusting. A square gangbolt gives the disk gang extra strength. Extra-long triple lips on the inner race, combined with a wide seal between the outer race and flange, flex to resist wear, keep dirt out, and help maintain lubrication.
Bearings are self-aligning and greasable for longer life.
And they re backed with a two-year warranty. Welded steel spools add protection. Either way, soil and residue are directed backward rather than up toward the disk gangs where they can interfere with the disking action. Wheel modules are maintenance-free. Unlike the joints in other disks that wear over time and distort depth by increasing play in the rockshaft, John Deere disks feature maintenance-free wheel modules.
