Thoroughly Mix Residues
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.
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.
Easy Soil Preparation
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
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.
Trailed Optimer+ models can be equipped with front gauge wheels to till the soil perfectly. These wheels are hydraulically assisted for more comfort.
Right Side Deflector Disk
The deflector disk keeps residue and soil clods from in line with direction of travel for ideal mixing.
Rear Leveling, Spring Tine Harrow
The rear leveling, spring tine harrow optimizes soils and residue flow for a level, even finish.

Customer Spotlight: Optimer+ 1003
John Borer General Manager of Edelweiss DairyRead this review
“When we bought the Optimer+ (KUHN Optimer+ 7503 Compact Discs), we were looking for a machine that could prepare a good two- to four- inch seedbed for corn after running a manure dragline through it. It certainly helped us achieve our goal.”
