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. 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. And there's no wear in the joint to affect depth.
