I just bought a 2001 Kubota B7500. I find it unstable on even a small slope. Also it has a front loader and seems very light in the rear. Doing any work with the loader or even going up a grade, the front wheel dig in while the back spin....suggestions.
I understand you can switch the back and maybe front tires to get more wheel base...as yes weight will help but is it worth putting calium in the tires...how much weight will be gained for a tractor that size??

re: Kubota B7500 stability and use
I don't have front end loader (FEL) but think you will find the front tires are not to be widen with FEL to keep axle strong. The rear wheels probably can be widen with changing the wheels from one side to the other. I don't think that tractor has two piece rims if so then you have other options than just switching the tires from one side to other. I assume you recently bought this and trust manual came with it. Read it, Kubota does a good job with their manual. If you go to switch the rear tires don't forget the front axle pivots, so don't just use one jack but block both sides so the tractor does not move when the first wheels weight comes off of it. Can be very dangerous.
1. Is your real axle adjusted all of the way out? I do a fair amount of side hill work and this has helped.
2. Are you loaded in the rear tires? A weight box or rear ballast or both are required for any loader use.
3. If you are carrying a load slow speed and low range 4wd and keeping the bucket close to the ground. The articulating nature of the front of these B's makes them somewhat unstable.
4. What type of tires do you have? Have you check the pressures?
This is a fantastic forum. Please post your questions here because it is way better to learn from the mistakes of others rather than repeating them. A rollover is no joke!
For what it is worth I have a 7510 with the LA302 loader.

re: Kubota B7500 stability and use
The bucket aids stability when low but transfers relatively more weight to the rears when raised. Another factor is the tire tread-type. I'd get the rears ballasted in any case. If the valves are not corrosion-proof and they use the common calcium, have the valves replaced first.
William;
The drift I get from your post tells me you're new at tractors. The posts above are all good information and especially the warning that rollovers aren't a joke, they can be deadly.
None of us are trying to scare you away from tractors and it's good you recognize tha they are'nt a toy. A lot of us here have been driving tractors since we were ten years old, but that doesn't mean we are immune from making mistakes, we all need a safety reminder now and then.
I'm assuming your tractor has a roll bar so always fasten the seat belt. Start off slow and easy, you will soon find your comfort zone.
Frank.
