There are two very different "Eicher" tractors. One was an older German maker that no longer exists and one is a modern brand lable made in India that is now owned by India's TAFE.
If the latter, they use to have a website but I no longer find it. I can't tell you their dealer or support base. Tractors may be great and looked fine from what I remember, but.
TAFE use to market here in the U.S. but they too are hard to pin down today.
What is the situation exactly?
