Tackle Tough Residues
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.
Disc Blade Suspension
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
Mechanical Depth Control
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
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.
Steady Control is a ground-following option for the Optimer XL 6000 and 7500 models. This KUHN exclusive controls the hydraulic pressure on each section using the tractor’s hydraulic compensation. If the ground contours force a section to go up, the rising pressure returns some hydraulic oil to the tank, while a decrease in pressure would bring more oil into the circuit to compensate for low-lying areas. In this way, a constant pressure and uniform working depth are maintained. Uniform depth provides agronomic advantages, since all seeds will be placed in a similar environment to promote consistent emergence.
All Optimer XL 100 Series (mounted) models come standard with the T-Liner roller. The T-Liner measures 23.6” (600 mm) in diameter and works best in medium to heavy soils. The scrapers help to keep the roller clean in sticky conditions, while the solid tube design reduces the chance that rocks become jammed in the roller.
Single Tube Roller
The Single Tube roller is an available option on the Optimer XL 100 Series models. This roller features round bars arranged in a spiral pattern around the central axis, with an overall outside diameter of 21.7” (550 mm). It is lightweight for easy tractor lifting and performs best when crumbling and finishing light to medium soils. The Single Tube is less favorable if you work in sticky and/or rocky soils, as there is a greater potential for the roller to clog or stones to jam between the bars.
The Flexliner roller is offered as an option on the Optimer XL 100 Series models. Steel strips are attached to the central bar and can flex and spring as they roll along the soil surface. With a 21” (540 mm) overall diameter, this design works well in spring seedbed preparation applications.
Double U Roller
The Double U roller is offered on the Optimer XL 1000 Series models and is perhaps the most versatile roller in the lineup. It features two rows of wheels mounted in a staggered pattern, all of which measure 23.6” (600 mm) in diameter. This design helps the soil to flow through the roller and also helps the roller to self-clean. The Double U roller works with all soil types, including heavy and sticky soils, and offers good leveling ability.
Double Tube/Bar Roller
The Double Tube/Bar roller is offered as an option all Optimer XL 100 (mounted) and 1000 Series (trailed) models. The front (Tube) roller consists of round bars arranged in a spiral pattern around the central axis with a diameter of 21.7” (550 mm), while the rear (Bar) roller consists of flat bars arranged in a spiral pattern with a diameter of 16.5” (420 mm). This roller offers excellent stability as well as crumbling and leveling medium to heavy soils.
