I purchased a used M7060HDC12 about 18 months ago with 1100 hours. I have noticed an intermittent vibration in the rear end, and if pressed, would say it is on the right side. This occurs at all speeds, and feels like I am going over highway rumble strips. It occurs as the wheels (ag tires) rotate. Vibration interval seems consistent - more frequent at higher speeds, and less so at lower speeds. It has not gotten worse or better. The rear wheels have wheel weights - not filled with fluid. I keep around 15lbs pressure in the tires. I have pulled the hydraulic filters and there are no signs of metal in the oil or filter. An independent mechanic looked at it and is baffled. Local dealer won't service it as I did not buy it from them. Is this a tire issue? I think the tires are the orignal OEM, and the tread is even with little wear on them. Wheel lug nuts all snug. Any ideas? Thank you!

1st.....If the local dealer IS a Kubota dealer, they're supposed to service Kubota !

2nd, any chance the right brake is slightly on ?

The local dealer is useless. They are happy to sell equipment, but have zero interest in providing service. I am still waiting - 1 full year - to have a new 10' Bushhog 2310 repaired under warranty that I did purchase from them. Tractors purchased elsewhere have to wait until the shop is current with repairs which in effect means not gonna happen. The tractor has to remain on their lot until they get to it.

I had not considered a brake issue. Both brakes work as intended. Same pedal travel for both. I'll explore that further, though. Sounds plausible.

Thank you.

You might also consider cab support bushings. I've seen cases where deteriorated bushings can cause some strange effects. Noises, vibrations rattles, clunks, ETC. Your vibration may not be in the tractor but only in the cab. I would take a large prybar, go around and pry upwards on all four corners of the cab as close to mounting bolts as possible to see if one or more of the bushings seems looser or different from the others.

Check that wheel lug nuts and weight bolts/nuts are all torqued properly.

Are the tires filled? if so are the over full or under full and the fluid is sloshing over the top of the rim? I don’t know if that could happen but I can see it making odd vibrations if it did!

I'll check the cab mounts later today when I am back at that farm. I had not considered that at all. Many thanks for the suggestions.

The tires do not have fluid, but I do have wheel weights. All the nuts/bolts are tight to torque specs.

Sounds too simple, but are your 3 point arms hitting the inside of your rear tire?

That will have the effect you described to a T.
