Your benefits

Thoroughly Mix Residues

Optimer+Disc Blades.png

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 working in large quantities of plant residues, shredding crop residues and ensuring even mixing of the soil and 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.

Increased Clearance

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

Easy and Simple Adjustments

Compact Design

The Optimer+’s compact design and small overhang means it can be adapted to most tractors. With simple adjustments, working depth can be continuously adjusted using an easy to access stop screw and a graduated plate.

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.
