Tires Rear Wheel Spacing

[Citydude]

Citydude, That's some serious wheel width! Where did you go for the spacers? Any issues with axel stress?

I got the spacers from Motorsport Tech. I've got 150+ hours on them with no axle issues and absolutely the safest machine I've ever ran on slopes.

Thanks for the input. Always a wealth of information, and greatly appreciated.
Has anyone swapped their own? Was it a Pain in the ***? Mine are filled 3/4 with water and Methanol.
Anyone else have any photos showing the tires set wide?

If you've never done it before, yes it is a pain in the behind.

I haven't lately, but routinely did so on other tractors as has my brother. I wouldn't recommend trying it alone if you don't have an engine hoist or another tractor. It's much easier and safer with a partner; very easy to lose control of a loaded tire and get hurt.

At my age, I just call the tire service if my brother or sons are not handy.

When you say reverse the rim and then place it either inside our outside, are you refering to placing it back on the same wheel or the wheel on the opposite side of the tractor. If it's the same wheel, wouldnt that change the direction of the tread?

Look at page 62 of the OM, I was trying to verbalize what it was showing. When I had mine spaced out, they had to change sides to keep the tread in the correct direction. My rear tires are marked for "traction" and something else. The local Kubota dealer knew what to do and did it.

Saved (stole) this from a thread a long time ago, cause the topic keeps coming up.

I done it once 20 years ago. I was younger/stronger then. It was a little scary even then. This was a full size Utility tractor tire too. A smaller CUT would be a lot better.

The one he mentioned was that the rears would not follow the front tires exactly.

I flipped the fronts on mine too. Only downer is the valve stem is on the inside which is really not a problem. I think it only supposed to go on one way(lug nuts), but it works fine. I have narrow trailer ramps so I needed to make this change..

Mine are all the way out.,

So based on the chart above, and the pictures below, which setting 1-4 do you think these wheels are at?

I think it is three, but hard to tell for sure, on the main rim from the photo

I was thinking three also. So I should be able to get 4" +/- more going to option four.

they look like setting three to me also.

Well according to the chart a L4330 can't use #1 (no clearance), it is #3 because the rim is behind the disc.

For #2 and #4 the rim would be visible in front of the center disc.

Thanks again for all the photos and good information.
So for my next question. Assuming that a slope is consistent in angle and dry, at what grade should I be concerned about running along with versus running up and down? This is with the FEL and 6' bush hog attached.

This is a 50% grade or 26.6 degrees, with the 7' brush hog on the front.

Don't think I would try it on a tractor. :shocked:

I have seen the MoDot boys mow all day on slopes worse than that.. Scares the "p" out of me just watching.

But their tractors (mostly New Hollands, and some old Fords) Are set really wide, and some have "squat" tires and wheels.

If you mow at night with lights on your senses won't kick in and you'll be able to hold it! I did this once while mowing late, the tractor can take more then your senses.

I was set to switch my L3130's rears to the max spacing, but since they are filled, I was waiting until my neighbor got his engine hoist back. As it turned out, the "right" L3400 came along, and I sold the 3130, but other than the weight, I didn't think it was going to be too bad a job. With the right tools, of course. Now I am contemplating adding some 1.75" Kubota spacers, since the non-Grand L tractors like the L3400 don't have all those nice adjustments built in.

If I spread the wheels out to the max, will wheel weights help or hinder traction when running across the grade?
