How old is the plow? It sounds like it's doin gwhat my Diamond did- after about 15 years of plowing, LOL! It was a good blade- still have it, going to straighten it out next year and put it back to work. It's never really hit anything other than banks, just started to bend back on each side form use, we tend to get a lot of snow in my area. I'm glad it's nothing major- but you might want to keep an eye on it, and if its bending near where the ram mounts possibly reinforcing the back of the blade to keep it from bending any further. At least you know what the problem is and now you can watch it and figure out how to correct it, or at least keep it from getting worse
