Weed control in young plants

With the Thulit, Lemken presents its first weeder harrow and rounds off its range of mechanical weed control implements. In developing this machine, the company broke new ground to now launch a new concept with four beams and eight rows of harrow tines. The Thulit is specifically suitable for weed control in young plants.

Complex spring combinations are replaced by an innovative hydraulic tine pressure adjustment, which ensures that the tines deliver more even pressure across the full working surface. The pressure can be continuously adjusted to up to five kilograms while driving. As a result, the Thulit effectively works during the sensitive crop growth stages.

The tines are arranged with a line spacing of 31.25 millimeters and ensure blockage-free work. Stable, true-to-track and wear-free tine bearings ensure optimum weed removal. A straightforward quick-change system makes it easy to replace the harrow tines. The Thulit features precise and continuous ground contour following with consistent tine pressure, making it a versatile implement, even on very uneven ground and in ridge crops. Due to its clearance height and design that removes the need for the usual springs, it is almost impossible to find plants getting caught underneath the frame. The flexible hydraulic system further supports width section control within the frame sections to avoid multiple passes across parts of the field.

Minimising the frame weight was a core aim in designing this machine. To achieve this, the number of moving parts was significantly reduced in comparison to similar models, ensuring that the Thulit can also be used easily with tractors with low lifting capacity. The driver has a clear view of the harrow tines during work and therefore a constant view of work results. For transport, the tines fold in automatically for an increased level of safety.

The Thulit harrow will initially be available in limited quantities in working widths of six and nine meters in spring 2024.
