I have a welded blade on my mower right now. When it broke the dealer didn't have any in stock & I wanted to get some mowing done. I ground both sides & welded with 6011. Finished the weekend. Will get 2 new blades this week. They can be welded although I wouldn't rely on a welded blade as a permanent fix. BTW I don't have an irrational fear of liability but I don't allow bystanders either. MikeD74T
I'm not telling anyone what to do, but I'd highly recommend against welding blades to repair a blown out bolthole.
According to my math, 17,000 fpm works out to be over 190 mph blade tip speed. The fact that they can be welded doesn't mean you should do it. Folks, do not do this. Dis-similar metals (can be a good thing with proper metalurgy), loss of heat treatment condition...I don't have anywhere near FMJ's experience but I would take a WAG that the blades were nearly worn out and the metal around the holes was work hardened/fatigued which contributed to the failure. Just my guess.
A dealer without bush hog blades in stock needs to light a fire under the parts manager.
