Claas Celtis 446 RX

[rexbrute]

Hello. I recently bought a Celtis 446 with a supposed transmission problem.
While in any gear, it's power is significantly lower and it makes a constant friction sound depending on the rotation speed. I barely got home with it, because it's quite hard climbing a hill.
What could be the problem? I thought maybe the clutch. But it seems 4x4 doesn't work as well.
I don't have a service manual for it.

Hey, we have Celtis 436 with a very similar issue and I was wondering if you have resolved yours?

When you start the tractor and put it in gear and release the clutch it makes an almighty shuddering noise which feels like it's about to fall apart. We learnt that fiddling with the trans fuses will temporarily fix the issue until you restart the tractor.

The only thing we can think is there's a faulty sensor on trans that resets when you pull the fuse

Also when it shutters the half gear doesn't work
