KUHN has announced a new 12 metre model has been added to the popular OPTIMER range. It is the first 12 metre machine to feature KUHN’s unique STEADY CONTROL system which maintains a uniform working depth, even at higher speeds and on undulating land, regardless of soil conditions. Product specialist Edd Fanshawe explains:

“STEADY CONTROL exerts equal pressure across the full 12 metre width of the machine. This means the discs all cut to an equal depth even when the ground is undulating because the OPTIMER compensates for ground contours by adjusting the ground pressure across the machine’s five sections.”

The 12-metre machine can also be run at up to 15 km/h whilst maintaining a consistent depth across the width. “This will help larger farmers and contractors to cover the ground faster and more consistently with approximately 45 acres possible in an hour,” he adds.

The OPTIMER has been continually updated and the XL range is now available in mounted and trailed models in working widths of 3 to 12 metres wide. All models feature independent 620mm diameter discs which can work at depths of 5 to 15 centimetres. When folded, the 12-metre model is just 3 metres wide and 4 metres high.

“With an OPTIMER XL operators can choose from a variety of models to suit tractors from 90 to 600 horsepower. All can improve the management of residue such as maize stalks, and green cover crops, and are available with five different roller options. On the smaller width machines, a KUHN SH 600 small seed drill with a 600-litre capacity hopper can be added. This enables stubble cultivation and cover crops or cereals to be sown in just one pass,” he concludes.
