Tractor rocks going down the road

[Fritzy]

I have a 3030 with a Cab which I use for snow blowing and cutting Grass. Most of my accounts are in town about 5 mile away and sometimes when the trailer is busy on other jobs I drive the tractor into town. The problem I have is the tractor at full speed rocks from side to side, not nice to drive. It's a little better if I drive on the gravel but it still rocks. does anyone know why it does this?

Flat spots in the tires from sitting

Maybe for the first few minutes but it's a good 20 min to get into town, I would think the tires would even out by then.

Do the tires have liquid ballast? What type and how full?

Does it do it at a rate that seems to coincide with the rotation of the front or rear wheels?
I have an idea...

bent rim

My tractor didn't do it, but it does bounce after I got the tires full. I think at certain speeds the liquid kind of flops around in the tire causing it to bounce. Is that what is happening to you?

My B26 does it when I'm in 4WD and as soon as I pull it out it handles like a baby.

It doesn't seem to do it in any rythum, it will do it for awhile and then stop then start again.
The rims look good, I don't think they are bent.
I don't run it in 4wd on the road I don't know if that would make a differance.
I don't have any liquid in the tires.

One of the things to think about is that I have never seen a wheel weight on a tractor tire.

This probably means that the tires are not balanced, which is fine at low speeds, but may lead to problems at higher speeds.

I have no idea how to balance a tire if it is loaded, but you might ask at a truck stop if they can balance unloaded tractor tires.

My L3130 did that when I first bought it. R4 tires not loaded. I jacked up the rear of the tractor and let the air out and reiflated them above the regular pressure and then deflated back to normal. It seemed to help some but not all of it. don't over inflate to much or the tire might be damaged. I thought that maybe the tire bead might not be seated correctly. worth a try.

Then prepare to get laughed off the property.

Duffster got it right... flat spots on the tires from sitting.
