Research and development project MuSt5-Trak
Development and field test of a multi-fuel tractor compliant with emission stage V
Based on a standard production diesel tractor the John Deere European Technology Innovation Center is developing a Euro emissions stage V multi-fuel tractor, which is capable of running on divers fuels (vegetable oil, biodiesel, diesel) as well as mixtures of those. For this purpose the tractor will get a fuel analysis system which will provide data for the management of the engine control according to the used fuel. This system will be tested in practical application. The multi-fuel tractor should be able to operate with different fuels and fuel mixtures in a reliable, efficient and low emission manner. This project should help to increase the market introduction chances of vegetable oil powered agricultural and forestry machines.
The overall goal of this joint research project is the development of a European emission stage V multi-fuel tractor with the highest possible fuel flexibility combined with a high level of operative reliability and a low barrier for biofuels regarding market entry. The first sub-project is carried out by the project coordinator John Deere and is aimed to develop an algorithm for fuel detection, which is later on tested by implementing it in an engine control software and testing it on a test machine. The second sub-project, which is carried out by the Technology and Support Centre (TFZ) is tasked with testing and rating sensors for fuel recognition and field tests of the multi-fuel concept. The third sub-project which is the testing of sensors on an engine test bench and the optimization of the engine is conducted by the TU Kaiserslautern.
The major project parts of the sub-project are:
- Evaluation of sensors
- Development of a model for fuel detection
- Emission and performance tests on the tractors with different fuels and fuel mixtures on the tractor test stand
- Field tests with the tractors with rapeseed oil as well as in multi-fuel mode

Like with the small project tractor, tests with the portable emissions measuring system were also conducted with the bigger project tractor. This measurements were made at the Lehr-, Versuchs- und Fachzentrum Almesbach (centre for education, experiments and expertise) of the Landesanstalt für Landwirtschaft (Bavarian State Research Centre for Agriculture) (link below), where the project tractor will stay for the rest of the project to be evaluated in a field test.

The picture is taken from a sideward angel from above. It shows a tractor in a workshop with opened bonnet. The tractor is connected to a complex device via a pipe to the exhaust, other tubes and cables are running to another device by the back wheel of the tractor, more devices can be seen in the background. In the foreground is a trolley with gas bottles, a tank with a petrol pump and a barrel filled with some liquid.
As part of the project there are not only test bench tests conducted but also tests with a portable emission measuring system (PEMS; link below). These measurements are used as reference for the emissions of normal agricultural machinery use and to be able to compare those results to the results of the test bench. The picture shows the project tractor John Deere 6135R with mounted emissions measuring system during a brake of the measuring run.
Emissions and performance test of the John Deere 6135R tractor, on the tractor test bench of the TFZ, to evaluate the initial situation of the tractor in original factory condition with rapeseed oil and diesel fuel.
On 18th of April the second tractor of the MuSt5-Trak project was delivered to the TFZ. As the other tractor this one will be tested on emissions at the TFZ before it will be sent to the LfL testing farm. Almesbach for field trails.

On 2nd of April the first of the project tractors of the MuSt5-Trak project was received from John Deere (ETIC) by the TFZ to be tested on emissions, before it will be sent to the testing farm of the LfL in Grub for practical field tests.
