The other day I was mowing a new account with very tall grass and I hit a 1/2 inch piece of rebar sticking out of the ground. I must have bent it over enough to shave a little bit off the top. Not 20 min. later, I hit a alluminum baseball bat. It looked like tiger stripes where the blade sliced through the bat. My mower still ran good and cut good so I was lucky. I just wanted to know what some of yall have hit in the past and how bad of damage it was.
