JOKER RT - Horsch Australia

5 to 8 m working width
Produces high quantities of fine soil within the germination zone
Efficient consolidation in the germination zone
No problems with long residues and shallow cultivation. High clearance because of mountings in pairs.
Improved operational results with increased speed
High working performance with little draft requirement
High working speed in general
Good penetration with aggressive, serrated discs and maximum machine weight
All-over cutting at low working depth

In which working conditions does the Joker perform well?

Shallow and fast stubble cultivation for quick germination of lost grain, interrupting capillary and ensuring incorporation of straw
Effective seed bed preparation after plough or cultivator
Incorporation of long straw and difficult residues (cover crops, corn stubble)
Smooth incorporation of organic fertilisers (manure, cover crops)

The Joker prepares a fine and consolidated seed bed with good conditions for germination.

Effective packing system ensures intensive crumbling and consolidation.

Joker 5 – 8 RT

CAN BE COMBINED WITH ADDITIONAL TOOLS

Optional knife roller for the Joker 5 – 8 RT

The roller covers the whole working width. Its diameter is 300 mm and it is equipped with 6 knives per roller for a very high rotational speed, thus additionally improving the crushing effect. The knifes are arranged in a slightly diagonal way to guarantee that the force is distributed evenly. The knife rest against the rotor to guarantee top stability. The whole system is pre-stressed hydraulically with up to 100 bar and protected hydraulically against overload. The new front tool is perfect for example for chrushing catch crop populations in spring or autumn as well as for a ultra-shallow stubble cultivation in rape, sunflowers or silage maize. The knife roller can also be used to fight the corn borer in silage maize stubbles.
