Rubin 12

The discs are arranged symmetrically in both rows. This ensures precise directional stability without lateral pull, even at high speeds and when travelling on slopes. The centre discs are offset to prevent blockages and ensure even cultivation across the entire surface.

The discs are angled at 20° to the ground. 

To the direction of travel they are inclined at an angle of 16° in the front row and 14° in the rear row.

This provides optimal penetration and ensures cultivation over the whole working width from 7 cm working depth. In this way, optimal mixing and crumbling results are achieved.

The concave discs on the Rubin 12 are attached individually to highly tempered, specially curved and coiled legs. The special shape provides maximum clearance between the discs.

This enables the Rubin 12 to operate without blockages, even with large quantities of crop residues.

The bearings of the Rubin 12 concave discs are designed as maintenance-free angular ball bearings, so that there is no need to lubricate or adjust them. Optimum seal against dust and humidity penetration The cap protects the seal on the bearing against wire and twine.

Each concave disc is individually attached to the frame with pre-tensioned coil springs. This means the optimum pressure is exerted. It also ensures that on hard soils the working depth is precisely maintained and the discs are guided on track. If there is an obstacle, the concave discs deflect upwards individually. Once the obstacle has been overcome, they quickly return to their working position. The springs are fitted with maintenance-free bearings, just like the discs.

An impact harrow behind the first row of discs provides intensive mixing and crumbling, while a levelling harrow behind the second row ensures optimal soil distribution and perfect levelling. Both harrows come as standard and can be quickly adjusted to changing conditions with a self-locking comfort setting.

Two mounting positions for the drawbar and a pivotable headstock allow a wide range of adjustments of the mounted Rubin 12. This is Ideal for hassle-free use with different tractors and in various soil conditions. Super convenient: The headstock for the upper link coupling can be easily swivelled to the front to achieve a greater lifting height.

On the mounted Rubin 12, the working depth is adjusted either with a series of holes or hydraulically. The levelling harrow is automatically adjusted to changes in the working depth.

The working depth of the folding semi-mounted implements is adjusted hydraulically. The depth indicator, integrated into the frame, can be easily read from the tractor cabin.

The folding semi-mounted implements are equipped with trailing rollers with self-levelling suspension. Both rollers oscillate autonomously, so that an optimal ground adaptation is ensured even with large working widths.
