I have the same problem with my 3140 with the the frontloader. When it warms up it starts to vibrate now and then. My mechanic thinks that it could be some kind of problem in the front pump. Do have to get it sorted out yet. I also had some problems with the three point linkage, like it was still pumping when you raised it all the way up. And when you shut the tractor off with the lift arms all the way up, they would drop down again.

That's what I'm thinking too, maybe a relief valve or something. Thanks for watching!
Nice video
Thanks Dad
