“When a farmer from the Douglas area approach you and says he is saving 15% on his irrigation costs because tilling his soil with Lemken equipment had improved the moisture retention status of the soil, you know that you are moving in the right direction,” says Karel Munnik of LEMKEN SA.
At the NAMPO Show regeneration in their range of combination equipment was announced, which will assist farmers in tilling even more biological material back into the soil.
The Karat 12 is an addition to the Karat equipment chain. In comparison with the well-known Karat 9, the new machine has four rows of teeth instead of three. The four beams have been placed closer to each other, making the machine about 30 cm longer than the Karat 9.
There are now more teeth that work closer to each other. With the Karat 9 the teeth were 27 to 29 cm from each other, but with the Karat 12 it is now 23 cm. The same teeth or shares are still used and the total working width goes up to 7 metres.
Karel says with more teeth in the soil more clean soil can be brougght up to the surface to be mixed with the material at the top; in other words, even more plant material can be returned to the soil.
The Karat 12 also displays the new LEMKEN design with the beam running from the front to the back in the middle of the machine, making it even sturdier and heavier, but also more streamlined.
The Rubin 10 disc combination implement was the main attraction of the exhibit. The Rubin 10 is the successor to the Rubin 9 and has undergone quite a few changes, e.g. the implement now works seven metres wide – one metre more than before. The Rubin 10 now connects with the tow bar and not any longer to the lift’s arms. It makes it easier to set the machine correctly.
Depth control is still managed by the rollers at the back, but there is now also an additional hydraulic adjustment tool with an indicator in the middle of the machine. The reason is that the front and rear of the machine have to be set to the same height so that it can deliver an even bed. On the three point machines there is only one indicator on the right at the back.
Each disc still has its own spring for fast release while the machine remains stable. However, the arms of the discs are not fixed to the beam with U-bolts. This has been replaced by a mechanism that has been welded onto the main frame.
The discs themselves have been replaced with Duramax discs, which have been hardened even more and made more substantial for a longer lifespan than standard discs. They are now somewhat bigger – increased from 620 to 645 cm. The discs have been placed 25 cm apart on the beam, but the back row cuts evenly between the front row for cutting widths of 12,5 cm.
The indents in the discs are no longer round but angular, which means it should have a more aggressive cut through material. The biggest change, based on input by farmers, is that the discs on the right-hand and left-hand sides of the machine have now been fitted symmetrically. Previously the front row discs faced to the one side and the back row to the other.
At times this made it difficult to keep the machine straight against inclines, or when working very hard soil it caused the rear discs to enter the soil a lot easier, which would result in side-pull causing the machine to pull in one direction. Now no sideways pull takes place, which also leads to less strain on the framework. Equalisers have now been placed between the second set of discs and the rollers instead of a second row of rakes.
Another more user-friendly change is the way in which the height of the discs on the side can be adjusted. Previously it was quite a process to lift the disc to prevent it from making a furrow in the seedbed. Now you simply pull a lever and insert a peg at the desired height.
When you do cutting only, the outside discs can also work deep and aggressively, but then it is no problem if furrows are created.
The Rubin 10 also has a new design with a strong beam in the centre. All hydraulic pipes and pistons are now neatly hidden inside the beam and the conspicuous blue machines have become even more striking!
