hi all . I read in classic tractor . that the crystal range was a joint venture with ursus of poland and universal of romania .zetor supplied engines and transmissions .Universal supplied front axles and Ursus supplied backend and hydraulic . i never heard this before is it true
 
Development started in 1964 at Zetor Brno. some polish engineers were stationed in Brno too. Universal (UTB ) got to build the front axles, Ursus got to build the rear axles, Zetor the engine and transmission. In 1981 the production was moved to ZTS Tees in Martin due to an international treaty about the reduction of arms production: ZTS built the T-72 tank in license from the russians, which suddenly became a slow market leading to unemployment.
To bring employment to that region, they moved the UR2 production there. Povaszke Strojarne then got to build the transmissions, a company that was later owned by HTC before they bought Zetor. They just discontinued this company, perhaps moved the production machines to Zetor ?

Anyways, when ZTS started doing their own modifications, the quality went down the drain. brittle rear axle castings, poor gearbox bearings, they cut costs on anything to stay in the race but it was too late for them. They went broke shortly after the Zetor takeover by HTC, but i guess HTC didnt find anything worthwhile there, as the UR3 was basic ally a Crystal equivalent. The UR2 rear end with its 16 speed was becoming dated, while the rear end was too light for 160hp (and in practice often tuned to 200) ever from the start.
 
From what year will you say the best models was made from ZTS Renze?
I have no experience with the latest models from Zts,because they was not sold in Norway.
There was only sold a few 8245-12245 in the early 90`s here i think. Not after 1994
The 8145-16145 seems to be great models. My 8145 and 12145 has only 3000 hours on the clock and they run like new.

 
No i say that the more changes ZTS made, the worse they got. 1 series were ok, 2 series were worse, 3 series was poor.
 
yes i would agree the newer they got. The worse they got . we had a good few crystal but the best was a 1974 .. its still earning its keep . has the old type hydraulic filters and the old type injector pump . was not oiled from engine
 
From the sound of it then, my 6745 UR1 is one of the better model Zetors, (despite it's shortcomings in the power steering dept)
From everything i have read on this site, the First of the 6cyl Crystals should be the best of the best ??????
 
I also think the Brno-buildt crystals was the best. I understand i have to take care of my 12011from 1979,not a oil leak,and 3bar oil pressure even with hot engine..
