Barry,
As a fair sized Zetor dealer,I am admittedly somewhat biased,but I also own one for my own farm (haying) operation.
I can honestly say that we just don't have problems with these tractors. Most all of our customers will freely brag about their Zetors purchased from us.
We have never seen the problem with the air compressor locking up---I suspect these may have occurred on the open station tractors where the compressor may have been left running continually.
Zetor is one of the few brands that still manufacture everything themselves--castings and all.
Parts have never been a problem for us--American Jawa cliams a 98% fill rate---our experience bears this out.
A few short years ago Zetor built some tractors for the green guys--even tried to buy Zetor.
Bottom line is--Zetor is a well-built, tough tractor,built for serious work, at a reasonable price.
We have never had a customer say he was sorry he bought one.
The 102 loader is similar in design to the Quicke-Alo loader, both of which are the best built agricultural loaders on the market, in my opinion. The 102 is designed for the tractor,has a massive frame, and is easy to attach and to take off.
Sorry for my soapbox approach--but you asked for an opinion.
