Hi all I have a MM2 with the insta act pump. Last weekend I ruined both of my angle cylinders. One of them I split the outer tube on Friday night and the other I broke the tube right off on Sunday. Both times I caught some frozen snow with the corner of the blade. I don't feel that I was going to fast or any faster than usual. My question is, could there be anything causing this or just bad luck. Also I've had this plow for 10 years with no problems like this. one other question where would be the best place to get new ones from Fisher?
