Mechanical weed control rethought

The Zürn TOP CUT collect cuts off the top of weed plants and collects the seeds in a bin. This improves field hygiene significantly.

Collecting the weed seeds

Especially intensive farming can lead to weeds developing resistances against herbicides. Common methods are no longer effective and many chemicals lost their acceptance in society.

With this background, Zürn Harvesting and French farmer and technician Romain Bouillé developed an entirely new approach for mechanical weed control. The weed collector TOP CUT collect is an intelligent combination of two tasks: Cutting the weed tops above the crops and collecting this material which contains the weed seeds. Hygiene in the field is improved sustainably by reducing the weed seed bank in the soil.

“Different scientific studies show that up to 40 % of the weed seeds are shedding before harvest. It’s therefore very effective to cut off and collect the top of these weeds before harvest. By doing this, the cycle of weeds getting into the seed bank is interrupted” says Zürn Harvesting managing director Rolf Zürn about the perennial field trials in France.

When cutting the grass weeds in their generative growth, the remaining plants are drying and not getting any new shoots. This is benefi­cial for harvest with a combine in heavy weed patches. This new approach is also a great opportunity for organic farms to extend their mechanical weeding toolbox.

The TOP CUT collect is especially strong when fighting resistant grass weeds like black grass, apera, wild oat or ryegrass. Furthermore, it can be a game changer in root crops which take some time to close the “canopy”.

Hohes Durchsatzvolumen

Die direkte Ernte von Biomasse mit dem selbstfahrenden Feldhäcksler hat sich gerade zur Energiegewinnung in Biogasanalgen etabliert. Besondere Herausforderungen an die Technik stellen hier neue Pflanzen und Pflanzenmischungen mit hohem Mas-senaufwuchs.

Der erfolgreiche Einsatz gerade bei der Ernte in der Königsdisziplin der „durchwachsenen Silphie“ beeindruckte auch die zahlreichen Häckslerfahrer der weit verbreiteten Baureihe Claas Jaguar. Aufgrund zahlreicher Kundenanfragen stellt nun Zürn Harvesting sein PROFI CUT passend für den Häcksler Jaguar des Harsewinkeler Herstellers vor. Das PROFI CUT Schneidwerk steht in Arbeitsbreiten von 5,30 und 7,00 m nun auch für den Häcksler Jaguar zur Verfügung.

Für den perfekten Gutfluss, und damit für eine hohe Ernteleistung und Häckselqualität, sorgt die große Einzugsschnecke (ø 808 mm) mit ihren konisch auslaufenden Schneckenwindungen zusammen mit den verstellbaren Einzugspaddeln. Passend für den Jaguar wird das Schneidwerk über einen federbelasteten Pendelrahmen mit zentralem Drehpunkt angekoppelt. Das sorgt zusammen mit der Auflagedruckregelung und einer in den Anbaurahmen integrierten Schnittwinkelverstellung für eine gute Bodenanpassung.

Auch den Testfahrern mit dem Jaguar fiel die Leichtzügigkeit des Erntevorsatzes in den verschiedenen Kulturen auf. Je nach Erntesituation konnten die erfahrenen Praktiker satte Mehrleistungen gegenüber ihren bekannten Schneidwerken feststellen.

Zürn offers Seed Terminator in Europe and CIS

The cutting platform and field research technology specialist Zürn Harvesting is taking over sales, production and service for the Australian “Seed Terminator” in Europe. The special mill technology almost entirely kills those weed seeds which come out of a combine. It was invented by the farmer and engineer Dr. Nick Berry who went in depth with this topic for many years as part of his thesis.

“With regard to increasing herbicide resistance and few new product authorisations, we need effective alternatives soon. Thus, we see a huge potential for mechanical weed control like this new concept from Australia.” says Zürn Harvesting director Rolf Zürn about the new collaboration.

The unique technology consists of two high-performance multistage hammer mills which process the residue coming from the sieves. It is now available for John Deere, Claas, Case IH and New Holland combines.

Mechanical weeding becomes intelligent

Zürn and Garford to cooperate

The cutting platform and field research technology specialist Zürn Harvesting has acquired a majority stake in the English hoeing technology manufacturer Garford Farm Machinery Ltd. The German family-owned company is thus expanding its product range to include the growth market of mechanical weed control and future-oriented camera-assisted machine guidance with individual plant recognition.

"In the future, we want to jointly use our experience and resources in sales, production and development to enable Garford to take further growth steps with its extensive hoeing technology programme. The increasing resistance problems with herbicides will open up new opportunities for mechanical weed control," is how Managing Director Rolf Zürn of Zürn Harvesting sums up the company's cooperation.

Further information on the products and the Garford company can be found on the website www.garford.com.

PROFI CUT direct cut header optimised for cup plant harvest

The PROFI CUT direct cut header demonstrates great performance in high biomass volumes and down crops,  for example in cup plant.
The PROFI CUT direct cut header demonstrates great performance in high biomass volumes and down crops, for example in cup plant.

Strictly trimmed for performance

Direct harvesting of biomass with the self-propelled forage harvester has been gaining increasing relevance for several years. Operators of biogas plants in particular are looking for extended crop rotations, new types of cereal and crop mixtures for energy production. In practical tests the cup plant has proven to be the supreme discipline when it comes to harvester throughput capacity and cropflow with tangled plants.

The benchmark for whole crop headers was therefore expanded to include this crop. Zürn has added a special „silphie kit“ to its harvesting technology to optimise the harvesting of cup plant: A passive roller crop press (in place of the rigid crop deflector pipe) allows the plants to glide evenly into the header. Special paddles have also been added to the intake auger in order to pull in the crop with an even higher force.

Field experience proves the high feeding capacity of the PROFI CUT in high and dense biomass crops. This applies not only to cup plant but also the harvesting of further crops, such as sorghum and tall wheatgrass (Szarvasi) or crop mixtures, e.g. vetch-rye mix.

For even more performance

Wolverine: The 735PF profi test report

What happens if you improve the "best header" once again? That's what the German farm machinery magazine "Profi" wanted to find out when testing the new PREMIUM FLOW 735PF in a weedy rye field. Check out the video to see the result.

“Converting the header to rapeseed [...] is almost child’s play. The massive intake auger is raised simply by operating the pump on the back of the header. You don’t even have to release the tensioner of the drive chain for that. Then you fit the [...] side knives, which may take some muscle power but not a lot of time. The crop dividers are unlocked and unhooked without any need for a tool, and the double knives simply take their place. Excellent! Better still, neither the electric nor the oil lines need coupling, because the knives are driven mechanically by a simple but ingenious overload clutch.”

Unmatched Versatility

Thanks to the specialy developed "Silphie-Kit" the PROFI CUT does an excellent job harvesting the perennial cup plant.

Clever solutions for all crops and conditions

The new PROFICUT direct cut header sets new standards in power and performance with working widths of 5.3 and 7 m.

The PROFI CUT is a universal tool for direct cut of biomass. It is designed for the highest throughputs no matter if you are harvesting classic whole crop silage, vetch-rye or cup plants (Silphium).

Thanks to the large working width, even the capacity of the most powerful forage harvesters will be utilized. If there is a little less yield on the field, the PROFI CUT will work properly up to a ground speed of 20 kph

Katja's Harvest Tour | USA 2017

In the upcoming months, we will be accompanying a German young talent as she embarks across the US for her harvest tour.

Before the great adventure, Katja explained, “I am from the beautiful Schrozberg in the south of Germany where my parents run a custom harvesting business.” The 20-year-old completed her apprenticeship at custom harvester Landtechnisches Lohnunternehmen Frank Scholz. After her graduation last summer, Katja moved to the US and admits: “Now I have fulfilled my dream of being in the land of unlimited possibilities.”

Katja is telling us what to expect in the upcoming months: „ The custom harvester Green Acres Enterprises has its home base at Elk City, OK. Every year they start with the wheat harvest here in Oklahoma, in the south of the country. Then they follow the harvest northwards to the Canadian border in North Dakota. Because of this we will be traveling a lot in the upcoming months"

Follow Katja and her harvest crew.

Research Transfer Prize from IHK Heilbronn-Franken conferred

On April 3, 2017, Chamber of Industry and Commerce IHK Heilbronn-Franken held its sixth “IHK Research Transfer Prize” awards ceremony. Three outstanding cooperation projects merging science and business were chosen to receive the prestigious award.

The gold award was given to Zürn i-Flow project, a result of cooperation between Rolf Zürn, Zürn Harvesting GmbH & Co.KG, Schöntal and Steffen Wöbcke, Institute for Natural Product Technology at the Dresden University of Technology. Under this project, an intelligent and automated cutting platform for combines was developed wherein all components can inter-communicate and adapt to the individual conditions and needs of the harvested materials.

Kirsten Hirschmann, Managing Partner of Hirschmann Laborgeräte GmbH & Co. KG, vice president of the IHK Heilbronn-Franken and jury member, congratulated the project partners on their success. He also highlighted the intensive cooperation between project partners and the innovation of self-optimizing technologies, as they relate to the theme of knowledge-transfer. The resulting intelligent control allows between 10-15% of additional power.

To encourage cooperation between research institutes and companies, IHK offers special “Research Transfer Prize” to 3 successful projects each year. All submitted projects are evaluated on the basis of their innovation level, transfer of knowledge, application potential and economic impact potential.

The new direct cut header for harvesting of biomass

The completely new Profi Cut 700 direct cut header is a match for even the toughest conditions with high-yield harvests and flattened crops.
The completely new Profi Cut 700 direct cut header is a match for even the toughest conditions with high-yield harvests and flattened crops.

Direct cut headers for challenging tasks are increasingly in demand for the biomass harvest. Especially when it comes to unusually long, high-yield, non-homogeneous or flattened crops, many headers reach the limit of their capabilities.

New benchmarks for more performance

That is why we added the completely re-engineered Profi-Cut 700 and ProfiCut 530 to our product range. With a working width of up to 7 m the headers set new benchmarks in performance.

The Optidisc mower bed supplied by Kuhn is lubricated for life. This disc cutterbar practically "chomps" through the crop. Power is transmitted via a 5-groove power band and distributed to the two cutterbars that are externally driven and synchronised. In keeping with the high harvest yields, the direct cut header features a large intake auger to cope with these great quantities.

RapsCompact Side Knifes for Draper Headers

Mechanical driven side knifes now available for right and left hand side mounting on the Draper headers of John Deere, Case IH, New Holland and MacDon.

Zürn rapeseed/canola side knifes are now also available for right and left hand side mounting on common Draper headers. The new side knife models are tailored to the specific cutting platforms.

Superior mechanical drive

Due to the proven purely mechanical drive, the side knifes convince by unmatched fast installation and removal. The slim design of the side knifes prevents unnecessary cutting losses. In addition, Zürn rapeseed/canola side knifes are running with very low vibrations, as there is no drive unit on top of the knife.

Agritechnica Silver Medal

Zürn PremiumFlow headers represent the highest level of innovation and performance worldwide.

This was confirmed again by the independent Innovations Commission of Agritechnica, the world's biggest agricultural fair. They awarded Zürn for its advanced technology again a silver medal.

Innovative Zürn i-Flow header awarded

Zürn i-Flow is a newly developed intelligent cutting platform generation to improve performance of large combines. For the first time all rotating drives are electrified, flexible in speed and torque and communicate with each other. Field trials confirm that harvesting performance, ease of use and durability rise significantly.

top agrar system comparison: "With or without Flow?"

"What are the advantages of the PremiumFlow technology with active transport compared to a standard cutting unit?" This question is answered in a large combine harvester system comparison in the January edition by the journal top agrar.

"Performance starts with the header." Special focus was therefore the comparison of the Zürn PremiumFlow belt conveyor header with the John Deere standard header: "Here the PremiumFlow
has clear advantages. The supply of material is a pleasure to work with, much more relaxing. Even in dense rapeseed/canola stalks there was no need to help out with the reel. The threshing unit is noticeably more evenly fed, the feeder house is distinctly less strained."

Regarding the power demand of the PremiumFlow header the top agrar editorial team was surprised: "The header with belts required no more driving power than the normal header. In addition, the more uniform crop flow generates substantially lower torque spikes in the drive train."

During fiel trials the maintenance of the PremiumFlow only made little effort: Wenig Aufwand hatten die Tester mit der Wartung des PremiumFlow: "The seal between the belts is worthy of its name. Apart from a little dust, we did not have to clean anything from under the service guards for an entire season."
