The serial production stands nothing in the way.

Plant oil drivetrain. Manifold are the ideas of tractor manufacturer to activate the production of environmental- and climate-friendly drive systems.

The Hart of the John Deere fuel-research beats at present also in the Waldviertel (Region in Lower Austria). In Oberwaltenreith near by Zwettl produces and review the company Waldland most plant oils, which are testet in the 2ndVegOil project. The research work operated by the European headquarter of the US farm machinery group in cooperation with some partners from seven EU-countries. On the end of the study evaluation is a concept in autumn prepared, by which JD-tractors could be operated environmental friendly and towards newest exhaust emission standards. On the way to that target operates European wide 16 tractors and deliver research data. Five of these are in the fielding in Austria. The tasks within the research project are clearly assigned: Germany is working on the engine technology, England develops appropriate engine oils and the Netherlands prepares a standard for the fuel quality.

The Austrian part is the advancement of fuels as of plant oil. “We are working on a procedure to reduce phosphorus, calcium and magnesium.” tells Hannes Blauensteiner who maintain the project for Waldland. These components fall out of the fuel like gas and could finally occur engine damage. The solution which found Blauensteiner and its Team is imaginable easily: After oil compression is the plant oil added a substance which admit removing unfavourable ingredients by oil filtering. “Essential is, that the system is applicable in decentralized oil mills and therewith a regional cycles can be created, so Blauensteiner.

The Practicability engage the 5,500 operating hours, which performed the Austrian tractors trouble-fee in test bench. Blauensteiner: “There is also a machinery present which vacates snow in winter-service. With a preheating establishment for cold starts come up no problems.” But bother with the new exhaust emission standard for diesel particle filter, by witch existing also problems with conventional diesel tractors and have still have to be solved. On fuels is John Deere testing oils out of rapeseed-, sunflower-, camelina-, maize germ and jatropha. Whereas the first one directly can be cultivated in Central Europe, was the East African plant jatropha admitted for test because its nut delivers oil which isn’t eatable however optimal usable for energy production. “Principled are working all these oils. The most experience we have clearly with rapeseed oil.” told Blauensteiner. One crucial point by realisation of the whole system will it be to standardize the oil for warranty and servicing guarantee by conventional trade with farm machinery. There were many times a lack by self-building equipment. “Some conversations with self-invented solutions are anyway no longer feasible because of the common rail technology.” destroys Blauensteiner some thinker illusions. By modern tractors occur 90% of the conversion on the electrical part. A substantial benefit compared to other alternative drive systems views John Deere also therein, that the sharpness of the food discussion is been taken. With 10% of the cultivation area for the oils can be used 90% of the remaining land for food- and feed production. Ought to a bottleneck by food production or any other market distortions can the tractors be operated with the same tanks anytime by diesel. Additionally be incurred protein feed – keyword rape press cake – as co-product in production. Basically views Blauensteiner by John Deere large willingness to launch the technology after conclusion of study. “Decisive will be the request. Interested parties can already register by local dealers.”
