Hey Tractortaylornut, is that Polish fellow near your location, in the U.S. ?? The Ursus tractor as well ?? Or is it an Ursus rebadged as Long 900 ?? We had a C-385 A few years back. It was a hell of a machine, when the bolts connecting the diff housing with the tranny ran loose, i just drove home (without knowing the exact cause of the oil leak and funny feeling) with it and at home, my brother and i saw that it was just hanging together in the cab mounts (thats why the cab floor squeeked) and in the transmission driveshafts, the bolts were all loose, and the fitting pins were out of their holes too, there was a one inch slot between the parts. After tightening the bolts, topping up 55 liters of gear oil, i continued work and this 20 year old machine did about 1500 hours after that little accident, and died at 14,800 hours.

Renze He comes here from the home office of Ursus, the newer tractors they ship over here some of the 4 wheel drive tractors with loaders have been breaking over the axle pivots. They have a severe design flaw the local dealer has fixd several all over the US. They have several bolts that run into the thinest parts of that casting then the loaders bracket is directly behind that. the last 10 were broken in the same exacts spot I suggested to make a bracket that runs all the wat to the front to hold it equally on both sides. Im making a few repair kits fr the dealer. I should see the engineer in a few weeks when they come to get the parts.
The fella says its in his home town in Poland. Ill have to ask him again when he brings the pictures back by here to scan.
I know the feeling of having a tractor fall apart I also know its a bad feeling when you see you own transmission fluid in the road on you return trip lol.

Oh yes, the MF licensed Ursuses are imported in America...
Sorry to say so, but that is just crap. They copied an MF design but used cheaper steels.

They are no match for the older Zetor developed series Ursus sell in Poland and all over western Europe.

You might not believe this when i, as a Zetor driver say that, but everything that Ursus built on their own, has these design flaws. The MF 300 series copies they sell in America, but also the C-360 they sold mid 70's.
Those C-360 series were originally a Zetor design (Zetor 5511, 1968) but the original design was a little bit mutilated by Ursus.

I know a dealer that sold both Ursus and Zetor. He said there was a C-360 they sold, the gear of the oil pump drive broke every year and a half. They replaced it three times, then they applied a minor modification so that a Zetor gear would fit. Then, the tractor ran for years without any problems.

The best Ursuses are the bigger 80-160 hp series, designed by Zetor, (but assisted by a small team of Polish engineers, that worked in Czechia from 1964-1968)

Ursus is a good manufacturing company, but they cant take responsibility for their designs.
