Seedbed combination
EXTREM

In order to ensure precise seed placement, growing conditions and emergence the seedbed combination EXTREM offers the following advantages:

• precise levelling of the soil surface
• exact depth guidance of the working tools
• uniform breaking up and crushing of the soil
• perfect mixing of fine soil and coarse crumbs
• optimal soil reconsolidation as well as compact seedbed

Perfect seedbed preparation requests ideal technology. The seedbed combination EXTREM mixes fine soil with coarse crumbs, which prevents sludging and water evaporation. Particularly important in this respect is the correct crumbler, but also the front levelling plates. To ensure that the seed can be placed between the crumbled (top) and consolidated (lower) layer of soil a compact, smooth-running machine which precisely keeps the working depth is needed.

1: Air and heat | 2: Water | 3: Fine soil | 4: Coarse soil crumbs

In order to specify the best possible seedbed combination for the different soil types and conditions there is the possibility to combine many different working sections. In this way, the best machine for every field of application, as well as for every objective in soil tillage and seedbed preparation can be offered.

The working depth of the sections is adjusted parallel to the ground via the breadboard. This ensures fast and simple, but still precise adjustment of the working tools. In addition, this ensures there is no need to readjust the 3-point-linkage of the tractor when the working depth is changed.

Double crumblers with different diameters follow the tine sections to ensure a perfect seedbed. As they rotate at different speeds, the crumbling effect is perfect. Serrated crumblers improve this effect in comparison to flat steel crumblers. A single row of trailed weeder tines is available as an option on all crumblers.

In order to be able to increase pressure to the trailed implements (crumblers), the bracing of the three-point linkage is designed directly to the coupling points of the crumblers.

The low traction point ensures good retraction of the working tools in the soil and smooth guidance of the machine. This guarantees optimum immersion and exact maintaining to the working depth even in heavy soil conditions.

The large-dimensioned, low-maintenance and completely sealed and protected ball bearings guarantee a long service life of the crumblers. The rubber buffers, which connect the crumblers to the mainframe ensure obstacles (e.g. stones) do not lift the working sections – this again ensures a quiet operation and increases service life.

In heavy, wet, sticky soil conditions without stones the combination harrow-harrow is most recommended. Two harrow sections are mounted one behind the other, each of them in the front is fixed to the frame with chains.

The frame, as well as the crumblers, are very well protected against vibrations via rubber suspensions. The machine works more dynamically and there is less force on the frame. The quiet mode of operation extends the service life considerably.

All EXTREM machines have been designed to achieve a transport width of less than 3 m / 9.80 ft. In addition, the design ensures that the machine does not sway or swing during road transport, which in turn increases durability.

The side wings can be easily adjusted from completely rigid to floating via handles. If the handles are removed, the wings can float downwards.

The safety hydraulic lock block fixes the hydraulic folding mechanism in working- or transport position. This guarantees a rigid frame over the entire working width during operation in the field or safe road travel at all times.

The spring mounted levelling plate of the seedbed combination (on variant 2E only the rigid variant is possible) is height-adjustable and can therefore be precisely adjusted to the field conditions. The possibility to adjust the position (”trailed” or ”forward”) will crush the clods, level the surface and even out the tractor tracks. The tools are running very smoothly and the working depth remains exactly the same. The levelling plate is a useful tool especially for springtime seedbed preparation.

In order to prevent soil being pushed sideways on the already worked area optionally side plates are available for both sides (for 2ZW/2FZ).

Spring mounted track loosener (1)
The spring mounted track loosener 32×12 mm / 1.26×0.47″ (1) can be easily adjusted to the track width.

Safety track loosener 50×15 mm / 1.97×0.59″ with duckfoot sweep 70 mm / 2.76″ (2)
For stony soil conditions optional safety track loosener, which are secured against overload by a pressure spring, are available. They are equipped with 70 mm duckfoot sweeps.
Both track loosener can be adjusted in height depending on the desired intensity.

An optionally available single-row of trailed weeder tines ensure a good distribution of organic matter on the surface. It also increases as final tool the exactitude and precision of the machine.

These are available for the VIBROSTAR to the front and/or to the rear (symbol image – variants vary depending on the design)
