Joachim, thanks for all the postings. I've always liked ZETORS - there is a lot to recommend them to any mechanically-oriented person....along with a few quirks.....
I'd agree that Czech design & manufacturing can be top notch. Exceptionally roomy comfortable cabs, too. They just feel quality.
Your 5011 seems quite the venerable machine. There aren't many places in the USA where ZETORS are popular or well known. That's a shame because they deserve better. In Greely, Colorado - a big Ag area - there is a large dealer who has been selling ZETORS for many years and they are locally popular there.
I seriously considered buying one from them several times in the last 40 years. Even went so far as to get some shop manuals to study. But in the end decided to switch to construction oriented machines rather than Ag type.
Thanks again for all the photos. I'd love to see a ZETOR designed to compete with the existing compact 4wd market.
