Zetor-1971 5711 model

I know this is an older model but does anyone have any information that might be helpful in deciding whether or not to purchase this Zetor-1971 5711 model. It seems to be in good working order. What flaws should I be taking a closer look at?

7 series is the best they ever made. faultless tractor, just old

By the way, where is it located ? Zetor only started selling in North America since the early 80's, they sold just a handfull of 6011 and 7011 before the 5211-7211 came in 1984...

And are you sure its a 71' ?? To my knowledge they started building the 7 series from 72' onwards. Its basically the same as my 5511.

May be too late, but I haven't been on forum much lately.
5711 is older version of 6011, the engine is the same, but gearbox can be older model, and cabin ofcourse.
6011 and 7011 have same 4 cilinder engine but 7011 has biger dissplacement and is stronger.
That tractor is verry reliable and not easy to brake down, so I guess it can't be mistake to by.

Sorry if posting to late
