An automatic control system designed to ensure consistent performance from multi-element cultivators has been introduced by Case IH in North America to help improve seedbed quality.
Case AFS Soil Command records the settings for different elements – such as discs, tines and packer – chosen by the operator and then automatically adjusts them as necessary to maintain the same relationship when one setting – the working depth, for example – is changed.

Case IH points out that soil structure issues resulting from inconsistent seedbed preparation can limit planting speed at a time when growers are benefitting from big increases in planter working speeds. An uneven seedbed floor gouged into a rough ‘surface’ from misadjusted tillage tools, inexperienced operators or a set-and-forget mentality during spring tillage operations can hamper planter performance, causing row units to bounce resulting in uneven seed spacing and depth.
Sensors in hydraulic cylinders on selected Case IH cultivators record the working depth and pressure on soil-engaging components, providing displays on an AFS Pro 700 terminal screen and enabling manual or automatic adjustment to maintain the relative settings of one element versus another.

On a Case IH Ecolo-Tiger 875 disc ripper, for example, the working depths of shanks and discs will become misaligned from the original setting if the operator changes the working depth of the tines. Fore-aft level and crumbler pressure adjustment may be overlooked when working depth of the True-Tandem disc harrow is altered – and AFS Soil Command is designed to correct such oversights.

The system is also available on the Tiger-Mate 255 cultivator and is operated through the AFS Pro 700 isobus display, which provides on-screen adjustments to create an initial cultivator set-up that is saved to one of four pre-sets.
