In the 80's when the Soviet Union fell apart and they were breaking up the huge corporate farms with their behemoth diesel tractors there was a huge shortage of smaller tractors and no diesel fuel to run them anyway. A friend of mine was shipping container after container of 30 hp to 80/100 hp gas tractors. They had to run good and the rubber had to be brand new because they would never be able to replace them. The Russians had no money but would trade anything they had to get these tractors. They apparently were making their own fuel to run the tractors on. We send a lot of WD's, M's, H's, 77's, 88's, 770's 1600, 1650, a few 100 and 30 series Case and a couple of MM's and almost no JD's because they did not want them
His agent who was a Dane would take just about anything in trade. Vodka, religious artifacts, weapons, fighter aircraft etc.
