The link worked for me, but unfortunately I don't read Chinese ideograms so it is useless. It could be just a rant from Chairman Mao and I wouldn't know the difference. :thumbdown:
I do know that Jinma has been making tractors in China from as far back as the 1950's, so I 'd say they are well-accepted domestically and quite likely to remain in business a good while longer. I don't know anything about the history or provenance of any of those other Chinese brands mentioned, though I do know Foton has a good reputation these days. In the recent past Foton's reputation wasn't as good as Jinma's, but that very well may have changed - the new Fotons look like pretty polished machines in the pictures I've seen.
