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.
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.
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.
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.
The award-winning electric driven cutting platform Zürn i-Flow is a joint development of several innovative project partners. Each partner contributed its experience to optimize not only the components in the respective areas of competence, but also to improve the overall system by cooperation.
Four medium-sized industrial companies
worked together for several years with two universities
By the interaction of theory and practice, an intelligent cutting platform was developed, which will improve the performance of the combination of cutting platform and combine.
The project was supported by funds of the Federal Ministry of Food and Agriculture (BMEL) based on a decision of the Parliament of the Federal Republic of Germany via the Federal Office for Agriculture and Food (BLE) under the innovation support programme.
Zürn Harvesting GmbH & Co. KG, in collaboration with its partners, has equipped an entire combine header with electric drives. Field trials in 2014 and 2015 demonstrated a significant increase in performance when compared with hydraulically / mechanically driven headers on the same combine. The trials revealed the following: the more difficult and uneven the crop stand, the greater the increased efficiency of the i-Flow header. In 2015 the DLG (German Agricultural Society) awarded the manufacturer from Hohenlohe a silver medal for this innovative header concept.
All the header components feature electric drives: cutter bar, conveyor belts, auger and reel. The dual function of electric motors is cleverly utilised: they serve as both drives and sensors. As drives, their rotational speed and torque can be accurately controlled; as sensors they supply information about load and working conditions.
The new drive concept is notably the first time that smart operation has been applied within a header: the cutter bar drive load provides the speed-related information for the conveyor belts and the auger. If the cutter bar is working under high load, for instance, the belts and the auger will run faster.
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.
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.
The product range of Zürn contains a complete family of header transporters for the new John Deere 600X cutting platforms. For the development of specific supports, interfaces and homologation test of the new header transporters Zürn partnered exclusively with John Deere.
The header transporter type SWW X6 has been specifically designed for the transport of 600X cutting platforms with large cutting widths. The all-wheel-steering keeps the transporter safe in alignment with the towing vehicle even on narrow roads and around tight corners.
Prior to the series production the new header transporters had to demonstrate their practicality in detailed simulations and pass the toughest load tests in the field. In conjunction with the specific header supports you will receive a transport system specially tailored to 600X cutting platforms. Only with Zürn header transporters you can be confidant that no damage will occur to the cutting platform during transport.
"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."
