Well done, Ken. That axle repair is not nearly as strong as a new axle, but it may be strong enough, and if it's not, you are now in a good position to replace it easily (though maybe not cheaply). It might be worth your while to keep an eye out for a second-hand axle as a spare, so you won't be out of action if the repaired one breaks, since you are using it commercially.
This thread is likely to be useful to others with hydro drive ride-ons. I'll now close it for the archive.
