just checked it out.
Zbyni, do you work for
Zetor ?
If so, could you ask the development department to investigate what ZF asks for their transmission parts (like splined shafts, 2400 euro for a Deutz Fahr Agrotron) ? I get the idea that, when Zetor maintains the part prices we are used to, they cant earn anything on it, so it would be better to build their own transmission so the parts revenue comes into their own pocket, not into ZF's pocket.
I just dont think a ZF transmission fits Zetors business model (of asking reasonable prices for parts, and sell many of them to owners of older tractors that are kept in working order because of the reasonable cost for parts)
Perhaps ZF doesnt ask this much for parts, and only Deutz, Fendt and Steyr put a 200% margin over it, but when i hear that a Deutz owner had to pay 2400 euro for a transmission splined shaft, i'm a little worried.
Also, the 7200 series rear axles are too weak, they are notorious for breaking when pulling heavy dumptrailers with 3 ton drawbar pressure, it often happens at Steyr 9145, Fendt 514 and DF Agrotron 150.
p.s. i repaired the link in your post.
