question Let's talk about Zetor prototypes and pre series models...

5441 and 5421 aka 5320/5340 was one of the most senseless models from Zetor . Only 6 hp more then a 43xx makes no sense.

No, i am not talking about UR1 Super but JRL Proxima: there was mention of a three cylinder 3.1 liter UR3 engine as base model, in the first brochures. Konedata.net even mentions them, although they were never advertised nor built and only existed in early brochures printed before the Proxima went into serial production

Years ago I have seen photos from a 5341 on nasetractory.cz on a CZ farm - but I dont know much about it. Possible its only a pre series model like the existing Maxterra was. I dont know.
I mean the cz 5341 at nasetractory was a 3cyl. Turbo ...

I found now only this:

ZETOR Polska

Traktory ZETOR , serwis i oryginalne części zamienne.

www.zetor.pl

and the attached PDF with some interesting informations about a 3 cyl prototype. But I mean I see this motor in a Proxima 5441 at nasetractoy. Possibly a modified selled prototyp Zetor 5040, I dont know.


But...
What have this model to do with differences betwen 7745 Turbo und 6340 Turbo aka 7340 and 7341 ?

UR V also UR 5 ?
Is this a official kategory from Zetor ?

Its a pre Proxima, wouldnt that be UR1 called?

Years ago I found this picture:

I think its a Zetor 5020 ?

And this:

Its view a 8040 and 9040

And... this one, called 7911, but I doesnt think its realy from Zetor...

Looks like a older version of 5020 or 8020 maybe?

Yes, the UR5 was a brand new gearbox with two overdrive gears like Fendt 300 series. Or so ive heard. Prototypes only.

UR5 or URV in roman numerals, it means the same.


Zetor 7945
As we can see there is URI engine
