This is going to cost.

This bracket came off our mower today but far worse was to come.

I saw a hole had corroded through the deck and tacked a plate on ready to weld it back to some sort of health, but when I stepped back I saw the underneath was riddled with smaller holes so gave up repairs after welding that adjustment bracket back into place, I didn't even bother with any sort of paint as the whole deck will collapse soon enough.
Now I seek a part number 532192556 at a price that doesn't make buying a new mower a better proposition.
