2024 Kuhn Optimer® XL 6000

Manage fall residue or create a spring seedbed with the KUHN Optimer® XL Series compact discs. Mounted and trailed configurations with a wide range of rear roller options customize the Optimer XL to help suit your needs!

The KUHN Optimer® XL is a heavy-duty, high-speed compact disc available in mounted and trailed versions to meet the needs of a wide variety of customers. As a “large-disc” machine with 24” (620 mm) diameter blades, the Optimer XL is best suited for heavy residue and deeper working depths. Each disc blade uses its own suspension arm and elastomer mounting blocks to clear obstacles without upsetting the rest of the blades.

Features may include:

Main Frame

Both the mounted and trailed versions of the Optimer XL are built on a strong frame with generous clearance underneath that allows soil and residue to pass through unhindered. Mounted versions use a rigid frame integrated with the headstock. Trailed versions have a large “backbone” that forms the main structure between the hitch and transport carriage. The discs and roller then mount to folding wing subframes that in turn mount to the main structure.

All Optimer XL models come standard with 24” (620 mm) diameter, notched disc blades. These blades are nearly ¼” (6 mm) thick for greater durability and a longer wear life. Each blade mounts to its own arm at a compound angle to create a high-quality cutting and mixing action. The individual suspension arms mean that only individual discs are affected in the event of an obstacle strike, rather than an entire gang. The suspension arms bolt to sealed bearings that are lubed-for-life with high-quality synthetic grease.

The suspension arm for each disc blade mounts to the frame with four polyurethane elastomer blocks. These blocks firmly hold the arms in place, yet have some “give” that allows the arm and disc blade to flex up and out of the way when an obstacle is struck in the field. Just like the suspension arms, the blocks are independent for each disc blade.

All Optimer XL models include deflector discs as standard on both the left and right sides. These discs catch soil and residue thrown from the disc blades and deflect it downward into the path of the roller, reducing the formation of ridges and promoting an even, level field finish. Each deflector adjusts in three directions: length, depth, and distance from the center of the machine, allowing the operator to fine-tune the field finish depending on conditions.

Easily Change Your Working Depth

Optimer XL 100 models feature a mechanical depth control system as standard. This design uses a series of shims that the operator can add or remove to change the working depth of the machine.

Hydraulic depth control is an option on Optimer XL 100 models and a standard feature on all Optimer XL 1000 models. Connected to a tractor SCV, the cylinders raise or lower the rear roller to obtain the desired working depth. Hydraulic control allows the operator to remain in the comfort of the cab and make quick adjustments as needed. There is a convenient gauge that allows the operator to quickly assess the current settings.
