Hi, I have a sears self propelled walkbehind mower. I've hit bricks, sticks, etc, and it works fine. However I hit a large stick the other day, and when I push down on the handles to raise the front wheels, [to turn a corner] it makes a loud racquet, like the blade is hitting something slightly. Is that just a bent blade or could it be the shaft? Is there a way to tell? Plus do I have to get the sears blade or will any 22" blade work?
thx
