RoTeC coulters are maintenance-free and work very reliably, even where large amounts of straw and plant residues prevail. The sowing disc and a furrow former create the seed furrow profile and provide optimum seed placement into the soil. The Control 10 depth guidance disc or the Control 25 depth guidance roller prevent the soil from sticking to the sowing disc, thereby ensuring that the pre-selected sowing depth is precisely maintained.

Row spacings of 12.5 cm and 15 cm can be chosen.

Advantages of the RoTeC coulter 

• High-performance single disc coulter for wet and cohesive soil types 
• High level of self-cleaning through the depth guidance roller 
• Decoupling of coulter guidance and reconsolidation 
• Up to 35 kg additional coulter pressure

The maintenance-free RoTeC pro single disc coulter
1. Tool-free adjustment of sowing depth in 3 steps.
2. Reinforced support arm with a coulter pressure of up to 35 kg. Central coulter pressure adjustment.
3. “Control" 25 mm or 10 mm depth control and cleaning roller for an even planting depth.
4. Furrow former for a clean profile seed furrow.
5. Seed guide tube up to the furrow former for even seed placement.
6. Sowing disc ∅ 320 mm made of boron steel, working angle of 7°, for smooth operation of the coulter.
7. Exact harrow for excellent seed coverage.

One of the unbeatable advantages of the RoTeC coulter is that there is no connection between depth control and the reconsolidation system. This means that the coulter is raised only once when passing a stone. Furthermore, the coulter and harrow pressure can be adjusted independently of each other. This very even and accurately controlled way of guiding the RoTeC coulter is ensured by the Control 10 depth guidance disc with its 10 mm wide contact area or the Control 25 depth guidance roller with its 25 mm wide contact area mounted directly on the coulter.

The basic setting of the sowing depth is carried out directly on the coulter in 3 steps without the need for tools.

RoTeC coulters are operated with a coulter pressure of up to 35 kg. In this case the actual effective coulter pressure is comparatively higher with AMAZONE, because the pressure is not distributed between the coulter and the following press roller, but acts solely on the coulter. When sowing rape, or early sowing in dry conditions, working with less coulter pressure is possible without any problem.

Robust and precise: The WS coulter is particularly suitable for single-pass ploughing and sowing, or if there is only a little straw, e.g. after rape or turnips. The hard cast coulter tip enjoys an enormous service life. For larger farms with hardwearing soils, the quick coulter tip change, where replacement is necessary, is possible by removing just one bolt.

The 3-row layout and the large coulter stagger prevent blockages in amongst the coulters. A funnel in the coulter guides the seed precisely down into the coulter tip. The back-up flap prevents the coulter outlet from being blocked when the machine is set down.

For WS suffolk coulters, the row spacing is 12.5 cm.

The sabre coulter tip was developed for very shallow seed placement on light soils or for mulch sowing with an average amount of prevailing straw. It can be replaced with the WS tip with very little effort.

Band sowing shoes are easy to attach and allow the seed to be divided into strips as well as helping to reduce the placement depth.

The Exact harrow covers and levels the open seed furrow without blockage even with large amounts of straw present. With its individually pivoting harrow elements, the Exact harrow follows the undulations of the soil perfectly, ensuring an even seed coverage on soils either with or without straw.

The harrow pressure is set without tools via the setting lever. On the hydraulic harrow pressure adjustment, a pair of locating pins predetermines the minimum and maximum settings. This way both the harrow and the coulter pressure are linked together and so can, during operation, be adapted to changing soil conditions by the use of just one tractor control valve.

The coulter pressure is mechanically adjusted centrally on the AD-P Special. As an option, hydraulic coulter pressure adjustment is available. For ISOBUS machines with hydraulic coulter pressure adjustment, a sensor that triggers an increase in seed rate is available as an option.

When creating tramlines, the marker discs automatically lower and mark where the tramline will be created. This means that the tramlines are visible prior to the seed emergence.

The Roller harrow additionally consolidates the soil above the seed furrow resulting in the optimum germination conditions. This is recommended especially for light, dry soils when sowing spring crops or rape.

An undulating surface profile that reduces erosion is the result. The Roller harrow, adjustable separately from the coulter pressure, can follow the ground contours over a range of ± 100 mm.

Stepless adjustment of the Roller harrow via spindles.

The centralised adjustment of the Roller harrow is carried out via the adjusters with overload safety device. As a result, the intensity of the Roller harrow pressure can also be very flexibly adjusted and the press rollers can even be completely switched off. So, the press rollers can, for instance during late autumn sowing in wet conditions, be lifted out completely. The drag tine harrow can be accurately adjusted via a hole pattern.
