6245 vibration

Hi everybody out there,
I went out to move some stuff with my uncles 6245 4 wheel drive zetor today and as soon as I started it, it began vibrating/shaking. It got better the faster the engine ran and made no difference whether the clutch was in or out (pto or transmission). Since it was pouring rain I did not really get into it. I was just wondering if anyone could give any advice on what the problem might be. It also has a loader.
Thanks so much for your responses.

I have 6245 with log grane. When im lifting 2 or 3 logs to bin without support feets it begins vibration. And when i open the grabber and drop logs off shaking stops. Any shaking either when i use support feet.

I suppose it can be the same, if you have loader on it. Its been bending whole tractor

Allthought there can be other reasons. Un balanced clutch, crankshaft balansing weight is loosing, etch etch.

Anyway, my 6245 hasnt broken.... yeat. But i dont care, when it breaks to half, i can take nice picture of it to all zetorworld people

It may be an idea to check the oil levels in the power steering tank and the gearbox, air in these systems could cause vibration, If they are OK I wouldn't use the tractor until it has been checked out by an experienced person.
