Tractors and Farm Equipment Limited (TAFE), has announced that its entire sub 100 HP range of Massey Ferguson and TAFE tractors, barring one model, has been made compatible for use with bio diesel. These tractors can use the current 5% blend of regular diesel with diesel produced by esterising vegetable oils obtained from Corn, Jatropha, Rape Seed, etc. Since use of edible oil for this purpose is banned in our country, oil from Jatropha is normally used for making bio diesel which is a green fuel, bio degradable and environmental friendly.
