4066R Vibration

moxiemeister · Apr 8, 2019

I have a 2018 JD 4066R with 100hrs. It has a pretty harsh vibration when driving that correlates with speed. I've checked everything I can think of. I'm wondering if it could be a front wheel alignment issue. It has done this since day one. Most of my time with it has been at speeds too slow to reveal it. I took it up the road the other day and it was almost violent.

Wondering if anyone else has come across this?

Sorry, I don't have a similar experience.

The only thing that comes to mind, especially as you say that the vibration occurs at low speeds (or is it 'lower' speeds?) is that there is a problem with the MFWD... in that, it's always engaged, despite what position the lever is in, or there is a "broken bit" in the front axle associated with it.

Do you have R1 tires on it?
Are they loaded?
And what is your tire pressure?
A lot of tractors with R1 tires will get rumble type vibration, some at most road travel speeds some it will come and go with the different speeds,
tire pressures and loading can effect it also.
