4wd on BX23 - not working?

Okay, some confusion here. I thought you were using a 3PH back blade and had taken off the BH to attach it which is why I asked about the hose hook ups. But I see from this that the BH is still attatched and is functioning fine so scratch that theory.

Reading the WSM reveals that if resistance to both wheels is equal they will both spin at the same speed. If you put a load on one you could expect the other to turn faster, this is how it compensates for going around corners. When one tire encounters slippery conditions it spins and robs power from the other. This is where the dif lock comes in. It locks both wheels together so (hopefully) the other wheel can get a grip and move the tractor.

Well, I hope that's helpful, but as for a diagnosis I'm afraid I don't really have any ideas.

Good luck and keep us posted!

Fuel delivery problem? /forums/images/graemlins/confused.gif

Changed your fuel filters yet?

I believe I found the problem. It finally stopped raining and I was able to take the tractor outside and take a look at it. The rear left rim is spinning inside the tire. The rear tires are filled, so I don't understand why I don't have fluid all over the place, but the seal around the rim must be gone in order for it to spin like that. I'll take the wheel off the tractor and bring it over to the dealer.

Thanks for the suggestions.

So in 2WD, the tractors not even moving much? I think you need a little more air pressure in that tire. Make sure that with the valve stem at the 12:00 position you are not blowing out pure water when you depress the tire valve. If so, you have to much water. Check the manual for the correct tire pressure.

Well I would never have guessed that! /forums/images/graemlins/blush.gif /forums/images/graemlins/grin.gif Maybe it was only supposed to be filled. I, for one, am looking forward to what they have to say about it. /forums/images/graemlins/confused.gif

The fluid has gotten between the rim and the bead causing the tire to lose its grip on the rim. The air pressure is keeping it seated.
I have heard of this happening on larger equipment. They may have to empty the tire wash it off dry it out and refill it.

Ahhh! This makes sense now, thanks for the explanation!

I have a hard time believing that some water or a bunch of water for that matter would allow it to slip. When we mount tires we use soap and water to mount the tires, inflate them and drive off. Granted the air pressure is higher. I would double check the pressure with a low pressure gauge.
