We have two Zetor tractors now, a 7211 (2wd, cab, 55HP +/-) and a 7745 (4WD, cab, 55 HP +/-). We use them for haying, the 7745 pulls a Hesston in-line baler and the 7211 pulls a NH 1037 stacker wagon. They are VERY easy on fuel and seem to have a ton of power, but we don't use them for much more than for haying. The downside is they are difficult to get into. The fenders are large enough that you have to do some shuffling with your feet around the clutch/gear shifters, but once your in- it's a VERY roomy and comfortable station to sit in. My dad and I are both over 6' tall- that's are only true complaint about these. As I mentioned before ,the fenders are large enough for tool boxes and even to sit on as they are cushioned. We have owned these for a little over a year now and we haven't had any mechanical problems to speak of. Dealers seem to be far and few between, our research shows Zetors are popular in Texas and surrounds, we have located a few within a few hundred miles from us, but knock on wood, we haven't needed anything. One thing I have learned from these machines is they don't have a replaceable oil filter, its a re-useable one.
The turning radius on the 4wd is about 1/2 acre at best.
