Kubota M9960 Rides Rough Please Help

I can't distinguish for sure because photos are so closeup but I think you can change rear rim that tire is mounted on to other side of tractor to widen tread(you could just unbolt rim and turn around but tire tread would be wrong direction). Most rear wheels have attaching points where outside bolts go offset to one side or the other

The L owners can verify this, but, I believe your rear wheels are two piece? Meaning the pieces can be separated and rearranged to change the width of your footprint.

The larger M series are designed with as many as six different width configurations on the rear and front.

Manufacturers almost always ship tractors in the narrowest configuration for obvious reasons. My local Kubota dealer sells them all that way unless the buyer requests a change. Rarely is that requested, and, around here most buyers never make a change.

It was one of the first things I did to my M9540. I work in steep terrain a lot.

Our L5740 has R4s and we had them set to their widest settings, like the M95/8540, there are several options. We had our M8540 set to the next to widest settings.

I can't tell for sure by your closeup pics
But, by the first pic it looks like the outer rim is bolted to the wheel center??? If that's true the adjustment is made by changing the position of the outer rim. Inside or outside of the center. Or reversing the outer rim and switching sides. It doesn't look like your centers are reversable and mine aren't either.

Before we added wheel weights.

Yeah, look at Larry's pic and you can see the number of changes that can be made without reversing the center.

He has his outer rim in most outward position because the lug is not welded to the rim in the center, it's offset. Then he also had the lug on the outside of his center rim, which moves the outer rim to it's widest position.

He could have his rear tires completely in under his rear fenders by simply repositioning the outer rim.

Makes a tremendous difference in ride and performance.

For me, I know of no application where I would want my rears at their narrowest configuration.

I, like Larry, run my M9540 in it's second from widest configuration.

SDT, how is the ride of your 9960?

Cannot say as I have not yet used it.

I have mine set to the second most narrow configuration (approximately 82" overall width) to allow use of a 7' rotaty cutter.

Yep, think that's where my 9540 was set when I got it. You are set up for a very rocky ride and minimal stability on steep terrain. If those things are okay with you, I'd leave it alone.
