The head sheared off a bolt on my robot mower (must have worked its way loose, must tighten up on my maintenance…!) and jammed against the underside of the blade disc causing the motor to detect resistance and stop, but not before chewing the disc up!
I’ve never had any success with screw/bolt extractors but had a set of small ones in the shop so with nothing to lose I set to.
Snapped three metal bits drilling the stainless bolt but managed to get a hole deep enough to get the extractor tool in, and out she came!!
New disc arriving tomorrow so he can get back out and catch up on his missed 4 days of work!
