Fast and Easy Metal Change
Cost Effective and Eco-Friendly Knock-on is a patented system* and the easiest way of changing parts on a cultivator, either to adapt the machine to the job to be done or to change wearing parts. This user friendly system is able to work from 3 down to 35cm in a very economic way in regards to the low pulling requirement and the cost of the parts which is at same level as the standard points. Kverneland always use the highest quality steels. This enables the Knock-on to use a simple locking system. The Knock-on system fits easily to the tine, requesting only a hammer to knock the parts in and out in seconds.
Economic‌ The bulb shape on the shares protects the holder system by decreasing the soil pressure on it. The holder can take several shares before it has to be changed, reducing the downtime dramatically.

1000g If the soil is wet or dry the shares will not behave the same way: 1. In dry soil, the point wears down to the end, the bulb continues to protect the holder.
250g
2. In humid soil, the point wears thin but will not lose its shape. when a hole appears its time to consider changing the point.
‌and Ecologic As a comparison, a standard reversible point (1300.g) worn out after having done the same number of hectars (been reversed half way) as the Knock-on parts above. Knock-on allows to use up to 75% of the original part, when only 60% with standard points, thus saving more than 200.g of steel each time a point is changed. Thousands of Kverneland tines will contribute to save a lot of steel and energy!

90% Down Time Saving! Knock-on is turning back the clock With Knock-on minutes become seconds! To change the points on a 3.00m unit with 10 tines it takes 1.30 minutes - while 20 minutes are necessary with bolted reversible shares.
Soil friendly The Knock-on range is full of possibilities offering 6 width of cutting with 80, 150, 250, 320mm shares and 360/470mm wing shares to match with various tine spacing and depth requested. The combination of the 150mm point and the wing shares 360/470mm is mostly used for shallow cultivation with 2 row machines. The wings can be removed quickly by removing 2 bolts when deeper operations are necessary. It is not easy to perform cultivation in ideal soil conditions every year. When work has to be done the machine should provide the best possible effect and cause the least damage to soil structure. Therefore, the Knock-on system offers a wide range of deflectors and tine protections which can be more or less active in boiling and breaking down aggregates. In wet soil a wide deflector should not be used. a narrow protection plate will produce smaller aggregate maintaining soil structure. This in addition will save fuel. However in optimum conditions a good boiling effect will be possible with the wide deflector. In order to make it easy and fast, the deflectors are locked by a single bolt.
Functional and Agronomic In the DLG-Fokus test the working quality of the CLC pro Classic was analysed. Power requirement, fuel consumption, working depth, crumbling effect and the soil density have been measured. The handling of the new share system was also evaluated in comparison with the standard bolted one by various people. Each time the necessary time to change the shares was controlled. For the first stubbling test the cultivator was equipped with the new share system Knock-on which is composed of 3 parts: share, holder and deflector. In test was the 320mm wide share with an 80mm deflector. These wide “A” blade shares of the CLC pro Classic are evenly cutting through the all width at 5cm deep (see pict.1). The residues were also well dispersed and incorporated in the top layer of the ground. Seeds of weeds and the previous crop were in good conditions to promote their germination.

For the second pass the same options of deflectors and holder of the Knock-on system were used. Only the wide „A“ blade 320mm was replaced by an 80mm narrow point. The working depth for this second run few weeks later was at the depth those narrrow point were working around 16cm, when inter tine spacing was around 12cm.
The graphics above show the profile of the ground before and after the pass of the CLC pro Classic. The reconsolidation of the ground by the Actipack roller was revealed in the top 12cm with a density of 1,05 g/cm³ in sandy loam and 1,06 g/cm³ im silty loam. As during the first shallow stubbling operation a good firming of the ground was possible through the entire working width. 1. shallow soil preparation

End users experiences... Frank Scholz is a contractor from Linsengericht in Hessen, Germany. He is enthusiastic about the new Knock-on system. He has been using the Knock-on on his foldable CLC pro with 4.0m working width and cultivated approx. 500ha. In Scholz` area, the soil quality varies from sand to loam. In the area around Hanau the rainfall is between 400-500mm, and on the Vogelsberg this can reach up to 1000m. There is also the physical obstruction at a depth of about 1.2m, of a water-impervious loam stratum. „I am satisfied with the cultivator CLC pro. With the Knock-On system I have been saving not only downtime this year but also the perfomance is very good with low power requirement and fuel consumption. The single parts of the Knock-On system can be changed easily so I am very flexible for all requirements. As opposed to the quick change system with screws I was using before I‘m very flexible to the needs and requirements of my customers.“
“I was using carbide tips on our CLC, but the Knock-on system is taking less power and keeps the best possible penetration capacity. I’m carrying a set of shares in the tractor cab and we can quickly change them in the field when worn-out or fit the wider shares for shallow cultivation to optimise fuel consumption. In our soils we can use 6 to 7 points per holder in a season, which makes it very economic when considering fuel and time savings.” Ludovic Chaillou, SCEA les grives aux loups, farming 300ha (France, Boufféré 85).
James Nott is farming a 900 ha farm near Sudbury in the UK and has been using the Knock-on system on his Kverneland CTC for 2 years. „The Knock-on system is simple, quick and easy, we like the extra depth the new point and holder gives the CTC. As the metal wears it does not lose its shape. In all soil types and conditions penetration is excellent.“
