Prior to the 1990's, Iseki made the Bolens large Garden/Small utility tractors. They also made the White compact/utility tractors... I believe this went back to the early 1970's if not before....
They of course are now making many of the Massey Ferguson in the 1200 series line, Agco ST Compacts and the new Caterpiller Challenger line which is really just the Agco ST's in Yellow paint vs. orange.
I happen to have a Grey Market Iseki which is basically like the Massey Fergusion ferguson 1125 series which was the machines out just before the 1200 series line. Mine is a 1993 model TA 210.....
