Curved Disc Blades

20”, curved disc blades, with large notches, aggressively shred crop residue and evenly mix it into the soil. The blades are angled, both horizontally and vertically, to work completely across the soil profile. The disc with notches excels in working in large quantities of plant residues, shredding crop residues and ensuring even mixing of the soil and residues.

Increased Clearance

Large arms provide nearly five inches of additional frame clearance, so you can power through even the heaviest residue conditions without fear of plugging.

Disc Attack Angle Inclines

The disc attack angle inclines to give the machine a large area to penetrate the soil. The shape of the discs provides intensive mixing of soil and crop residues.


Variety of Roller Options Available

Operators are able to choose from either a T-Ring or T-Liner roller for their machine. The T-Ring roller (shown) works well in clay or heavy soil. It provides the soil with even firming, while maintaining a smooth finish. It also assists with straw decomposition. The T-Liner roller comes in a solid tube design. It performs best in rocky conditions and provides good crumbling for the entire working width of the machine.


Low Maintenance Features to Save You Precious Time

Reduced Maintenance

The hubs on the Optimer+ feature a double row of oblique-contact ball bearings that are sealed and lubed-for-life to eliminate maintenance headaches for operators.

Independent Disc Protection

A system of four polyurethane elastomer blocks allows each disc to move independently in case the machine strikes an obstacle. With this system, the working depth will not be altered across the rest of the machine if it were to strike an obstacle.

Gauge Wheels

Trailed Optimer+ models can be equipped with front gauge wheels to till the soil perfectly. These wheels are hydraulically assisted for more comfort.
