B2910 front wheel snapped off!

Try praying the next time. It usually works better than cursing.

Haha...
no chance.

Not sure if they still offer the old part number or not, but the updated axle is P/N 32721-57323. It should be stronger than the original which is why they updated them. That P/N I listed is also used on the B26 industrial tractors, so they should hold up without any trouble.

My front loft wheel on my B2910 snapped of while clipping my field. It was a low-stress operation on the tractor. I found that it sheared from the axle on a poorly engineered and executed weld. The axle consists of a flange (to attach to the wheel) and a shaft, welded together and machined afterward to be the finished axle. The weld penetration on the inside was completely machined through, and the weld penetration on the outside was machined back to be less than .050" thickness. There was about .400" of interface with no weld penetration. This .050 of weld is what failed. The replacement axle was similarly fabricated, but at a larger diameter interface, with no obvious indication that the weld on the inside had been machined through. That indicates to me that the manufacturer became aware of this faulty design and took corrective measures for the new part. If this is true, I believe that the factory should have issued a recall and replaced them all for free. This could potentially be a very dangerous situation.

,,,,Thank you for the lucidity in describing this latent defect.:thumbsup:

So does that mean they will stand behind a sub-standard product?

Again, with what we pay for this equipment, we should not be receiving equipment better suited for a kids sandbox.

Not quite. They improve the part but still charge the victims of the original design defect.

Seemingly there was not enuf cursing at Kub for this. Customer complacence garners the minimum response.

It happened not far from where I broke the first one, way down in the woods. I remembered a suggestion here to lift the axle off the ground with the bucket and chain it to the frame and 3-wheel it out. It worked like a charm! I was back at my garage in 10 minutes.

Not to laugh at your mis-fortune, but I did get a chuckle after reading this whole thread including your ordeal getting it out of the woods the first time...3 hours!:laughing::laughing:
We've all been there at one time or another. I'm glad you shared how to do this easier.
