R 14 tires on a MX6000, Problem with vibration

[HEC]

I have a new Kubota MX6000 with rear loaded R14 tires. When driving on a hard surface like a driveway or road the tractor vibrates quite badly. I did have the rear tires set in their widest position if that makes a difference I don't know. When using tractor on the field no problem. Is this normal for R14 tires? I have a M5700 Kubota with R4 tires and no problem at all.

I have a MX6000 with R4 tires. I have only had it on a paved road a few times and didn’t notice a vibration beyond what’s expected for lugged tires. I don’t have R14, but would assume a similar ride to R4. But truthfully I seldom run on pavement.

Lower the air pressure and take it out of 4-wheel drive.

I have a MX5200 with loaded wheels and R4 tires spaced 3" out. I do notice some vibration on the road but I don't road it very much or very far. So I accept it. There is no noticeable vibration working at lower speeds.

I find a vibration at certain speeds with R1 tires on all the tractors I've driven. Changing ai pressure will change at what speed the vibrations occur. It is usually at lower speeds on hard surfaces. Felt at times, seen in the mirrors or open doors often.

YES

Thanks, I will try the lower air pressure and it is not in 4 wheel drive,

YES

Jeff, is that more of a problem because they are radial or just R14 style.

It is the lug tread on the R14 tires which is the primary cause of the vibration you feel.

Mine don’t vibrate on my very short dirt road trips around the corner.

Jeff it is almost like a shaking in the rear. Both rear tires seem to be running true as it almost feels like loose wheel nuts but it is not.The left outside mirror doesn't vibrate it is more of a shaking. I am considering having the dealer take out the juice in the rear tires if that would help.
