I owned a zetor 50 hp range several years ago , they have a great engine etc. but I had lots of small issues with it , brakes would freeze up if you didn't use it for a few weeks , leaky brake and power steering lines , and some other small issues . I was always able to get parts with no problem . My dealer no longer sold them so I sold it with very few hours on it . It was one rugged tractor and the fuel economy was probably the best I have ever had with that size tractor , again a great engine . They probalbly have all those little issues taken care of by now .
