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. ​

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 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. ​

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. ​

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. ​
