Well, I talked to my cousin today. Yes, we have checked the oil level, it is about 1/3 up from low to high level, should be enough for just raising a rake or so. And today I got a better picture of how the jumpy stuff acted... he says the rake lifted about 4 inches of the ground (that is about 10 cm for those who is in need of the metric system) and it was jumping up and down there... not raising a bit more... after a minute or so, he lowered the rake, and stopped the engine. And let it sit for a couple of hours or so, then started the engine again, and then the rake could be lifted as normal. Later the hydraulic has been weak, but today again it was mostly strong as it should be, he has been carrying wood on the rake all day long today. What makes the scene so tricky is that it has been changing so much, but, now I suspect that maybe it can be more than one fault playing games with us. Some suggest a leaking gasket or o-ring. The weak hydraulic indicates that... but then, how come it was strong again today ? The former owner also complained about a weak hydraulic, but maybe the TEF 20 was not as strong as newer tractors he suggested, and he was of course right about that. But, maybe he also knew things he did not tell us when we were there getting the tractor. When I talked to my cousin today, we realize that we have to take the lift cover off, and look what is down there. Maybe it can be the safety valve, that sometimes it does not seal well after being opened once in a while, maybe dirt in there, and then maybe the dirt goes away... Only thoughts from me... Bill
