With the Juwel, Lemken unveils a new generation of mounted ploughs

Juwel, which means "jewel" in German, is the name of the new generation of mounted ploughs presented by Lemken at the Agritechnica show 2009.
Designed to succeed the Opal range, this new plough is said to offer increased operating safety and greater control comfort.

Thanks to the completely new electro-hydraulic control system of the turnover head, the operator can adjust and save the plough's inclination directly from the tractor cab.

In addition, the clearance between the gauge wheel and the ground when the plough is turned over is significantly greater. This advantage proves valuable on tractors with low ground clearance, as well as on heavy five- and six-furrow ploughs.

The skimmers of the new Lemken Juwel have also been redesigned: their optimised shape and the modified position of the standard are said to ensure plugging-free ploughing, even in difficult conditions.

The working depth and the angular position of the skimmers are said to be adjustable simply and without tools.

All Juwel ploughs can be fitted with the new-generation "DuraMaxx" plough body, whose mouldboards and shares are manufactured without drilled or punched holes. This technique makes it possible to use extremely wear-resistant steels, which are said to guarantee maximum hardness and radically increase the service life of the plough body. Moreover, since the mouldboards and shares of the DuraMaxx plough bodies are wearing parts, they can be used right down to the end.

These parts are said to be replaced much more quickly, simply by hooking them onto the support. In a first, each individual share is also available in plastic, to better suit working conditions on particularly sticky soils and to plough at lower cost.

The "Hydromatic" automatic non-stop safety system is also said to provide extra safety: thanks to the maintenance-free attachment point, deflected plough bodies would return precisely to working position, even in difficult conditions.

With dimensions of 38 cm upwards and 20 cm sideways, the clearance would be more than sufficient to allow worry-free, uninterrupted work, even in deep ploughing.

The high release forces, which can be adjusted from the tractor cab to best suit differences in terrain, also help increase working comfort.

Another new feature of the Juwel plough is that the hydraulic gauge wheel is fitted with a built-in damper. This makes it possible to change the working depth even when the plough's weight is high and on difficult terrain, using only a double-acting valve.

Thanks to its bolted frame, the new Lemken Juwel mounted plough is said to offer remarkable stability and longevity. In the "OF version", the Juwel is suitable for both conventional and on-land ploughing.

For suitable and economical work, the plough is also available with centralised hydraulic adjustment of the working width. Lemken's "Optiquick" control is said to allow the width of the first furrow and the hitch point to be adjusted simply, quickly and independently.

The Lemken Juwel plough is scheduled to go on sale at the end of 2010.
