The first tractors with engines purpose-built to run on pure rapeseed oil with full warranty will appear at Germany's Agritechnica show in Hanover from 13th-17th Nov.
Deutz – which already manufactures engines specially designed for operation with 100% RME biodiesel – simplifies farmer fuel requirements still further with its “Natural Fuel Engines” fully guaranteed for fuelling with crude, unprocessed vegetable oil.
Certain Deutz Fahr tractors and a new Fendt model will be launched with the pioneer engines which range from 80hp to 330hp.
The system features two tanks, one for conventional diesel and the other for cold-pressed rapeseed oil or any other vegetable oil of comparable standard.
At the heart of the new four and six cylinder power-plants is an electronic fuel management system that automatically starts the engine with conventional diesel and switches to pure vegetable oil when the right operating temperature is reached.
