and rubber cutting edge. I built this pusher 5 or 6 years ago. It is built to last and works great. 3/8 steel with steel tubing bracing. Rubber cutting edge peels up hard packed snow well without hooking on every seem in the concrete and works great for grass or gravel to not dig in like a bucket or steel edge. The rubber edge is also gentle on blacktop surfaces. It has Replaceable shoes and built strong.
