Pioneering for mulch sowing

In 1978, AMAZONE launched its first rotary cultivator. Ever since then, this machine has set the highest standards in functionality and robustness when part of a PTO-driven seed drill combination. With its “on-grip” tines, the rotary cultivator is considered even today as the pioneering technology behind modern mulch sowing systems.

Unique characteristic of the “on-grip” tines
It is true to say that the birth of successful mulch sowing was, when AMAZONE introduced the KG rotary cultivator in 1978, a revolutionary development. Yet the most important characteristic of the rotary cultivator remains, since then, the “on-grip” tines, which pull the machine automatically down into the soil even in the heaviest and stoniest conditions where it reliably maintains its desired working depth.

First rotary cultivator 1978

The “on-grip” tines throw earth upwards so that a bow wave is created in front of the rotary cultivator. This is the basis for mixing organic matter with the soil, because the stubble and crop residues are mixed at the working depth of the rotary cultivator, creating the ideal preconditions for rotting down. At the same time, the “on-grip” tines ensure that the finer soil particles get into the lower worked area and the coarser particles remain at the surface. In this way, the seed is embedded within the range of the fine soil – ideal for a quick and even field emergence. In addition, the somewhat coarser topsoil, that protects from capping and simultaneously offers shadowing the plants, remains on the surface.

Initially the drive of the tool carriers was achieved by individual gearboxes on each pair of tines. In addition, the tool carriers were designed to pivot and were equipped with a spring back mechanism that allowed the rotor to breakaway to the rear when hitting hard obstacles. This “stone safety” did a good job, however the technical expertise in this was so complex that the rotary cultivator was too expensive and could not be justified by many farms.

Ingenious stone safety
So, in 1987, this technology was replaced by another ingenious invention: the spring suspended tine fixing. Ever since then the tines are fixed into the tool carrier in pocket shaped brackets which swage outwards at the extremes. It they hit a big stone they can twist elastically and do not break as the hard shock loads are absorbed. This saves the machine and, above all, the gearboxes.

As a replacement for the usual tine fixing bolts which had until then be used, the AMAZONE engineers additionally developed the now well-known quick change device secured by split pins.

Pioneering technology
Though the rotary cultivator, which today is offered in working widths of 3 m to 6 m, can be utilised as a solo machine without any problems, it was right from the beginning designed for operation as part of a sowing combination. And here, during seedbed preparation, not only does the soil tillage matters but also its reconsolidation and so AMAZONE launched in 1987 the tyre packer, another pioneering technology. In this way, the reconsolidation was no longer carried out across the entire seed drill’s width but only in strips, exactly there, where also the sowing coulters run. The successor of the tyre packer roller became in 1995 the wedge ring roller, which can be utilised in all conditions, both, dry or wet. This concept of the reconsolidation in strips has prevailed on a broad basis and is universally usable.

Until today the rotary cultivator and the wedge ring roller in combination with a conventional or pneumatic AMAZONE seed drill is the flagship of modern mulch sowing technology. And not only mulch sowing, however, but also when plough sowing as this machine combination provides the optimum preconditions for an even, clean seed placement yet with high acreage outputs.

The proven advantages of the rotary cultivator generation

10 tine carriers

10 tool carriers in a 3 m working width means plenty of space and rigidity. More space means more robust drive parts, stronger tines and an improved soil land crop residue passage.

AMAZONE: 10 tine carriers

In comparison: 12 tine carriers


Quick tine change system
The tines are just pushed into the pockets of the tine carrier and secured with a split pin. There is no easier and simpler way.


Integrated stone protection
The sprung tine fixing system allows the tines to yield when stones are encountered. The tines are firmly clamped in the socket in the centre of the tine carrier. The socket becomes wider towards the outside so that the horizontal part of the tine can twist out of position while remaining sprung. Much of the shock is absorbed when the tip of the tine hits a stone. This tine fixing system ensures the safe operation in stony soils and allows the tines on both the KX and KG to be used in the “on-grip” mode.


Quality within the system
Long-Life-Drive – the drive system for a long service life, maximum smooth running and high resale value. Gear wheels and bearings run in a single oil bath and so are maintenance-free – there are no grease nipples.

Stone torture test track ensures the highest load potential

The infrastructure behind the AMAZONE rotary cultivators also include the legendary stone torture test track. To enable the constant checking of the robustness of rotary cultivators and rotary harrows all year round, AMAZONE established last century the first stone test track. This proved itself so well that later on, for use in the development of trailed soil tillage machines, similar torture tracks were built. Ever since then, AMAZONE soil tillage machines are continuously checked under the highest possible loads both during the new development and also within the framework of series support so that they are optimally prepared to cope with the most arduous of practical operation.

The top benefits of the new generation

2 Adjustable levelling board
Another outstanding feature of the new generation machines is that they are also equipped with the new side plate which is adjustable via a slotted hole and are spring suspended. In addition, the working height of the levelling board can be adjusted irrespective of the working depth of the soil tillage tool as the board is guided via the following roller.

3 Universal setting tool
Height adjustment of the levelling board to match the relevant soil conditions is achieved, easily and from the left hand side of the machine with the aid of the universal setting tool.

4 Hydraulic depth adjustment
The optionally available hydraulic depth adjustment for the KX and KG rotary cultivators offers even more comfort and flexibility for the driver in so far as now the levelling board, guided in height by the following roller, does not require readjusting when setting the working depth.

5 Comprehensive roller programme
For the new generation of PTO-driven soil tillage implements, AMAZONE also offers a comprehensive range of following rollers. Here, in addition to the wedge ring roller, the PW tooth packer roller is available and the KWM wedge ring roller with Matrix tyres which, with its profile, produces more fine soil for the seed bed. Another alternative is the TRW trapeze ring roller. This roller with its trapeze rings provides a reconsolidation in strips, however, thanks to its good carrying ability, prevents too deep a penetration of the trapeze rings on light soils.

The range

Flexibility with the KX rotary cultivator

An additional milestone in the expansion of the range was the KX rotary cultivator which was introduced at Agritechnica 2009. Due to the quick change of the tines from the “trailing” position to the position “on-grip“ the KX can be easily converted as a specialist machine which is always matched to the prevailing conditions. So, for instance, in autumn the KX can be utilised with rotary cultivator tines and in the spring for the seedbed preparation with the rotary harrow tines.
