1. point - the hours by older Zetor's are engine hours not time hours like by other brands like Fendt eg.
2. thats a typical local problem - other countrys have other people and other people do more service for there tractor
3. in several markets Zetor dealers sells only with low prices to cam in a market with known old company names - that makes Zetor interesting for people with low budget and they often "forget" the service or just to clean the maschine.
I my home market (East Germany), Zetor has a real good relationship at the peoples here. Espacialy for the older models from 1982 up to 2000 they pay much more / hp for a Zetor then for some other brands like Deutz, Kubota, Branson, Case and so.
Look at my (one of 4) Zetor 5011 - for me the perfect tractor for my small "farm" (2 horses and 4 acres green for hay making) and business (inofficial Zetor parts dealer) as also for presentations on od tractor meetings and markets.
Its my helper in many situations for lifting, transport and agrar jobs like haying.
He has over 8.000 engine hours, and was produced in 1984 - he has the first engine, gearbox. New front loader from poland, new BKT tyres and I love them.
It is extremely manoeuvrable, consumes very little diesel and starts up without any problems even at -20°C. 45 hp are enough for a 5m hay tedder or a 2m disc mower. The front loader lifts 1,000 kg. It has a very well sprung front axle which is very comfortable on the road or when making hay. It has hydraulic steering, heating and ventilation, and of course a radio.
The best - I can alone without need any help fix it if its needed. Work ist easy and parts are here are here with us really very cheap in comparison. The TAX is also very cheap and he have no electronic inside, no ad-blue, no diesel particle filtre, no complicated rocket sience. ;-)
But yes - my heard is bleeding when I see some othe Zetor in some othe countrys when they are in bad conditions.
But that's not Zetor's fault, it's the fault of the owners who don't maintain and maintain it like any other tractor. Often enough, the Zetor is only refueled and maybe gets some oil, but everything else is omitted.
And this is what the machines look like - this is not a Zetor fault, this is a misconduct by some Zetor owners.
