I have a bank next to my house that get wet with a lot of rain, and slides into the road. The city comes along, and scoops it up the dirt, and hauls it away. Soon I will have no bank. I cover it with green house plastic during the rainy season. I hold the plastic down with metal parts. Wheel rims work real good. Disk blades work also. This is the first time I had blades missing. Some people use the blades like a large frying pan and fill with cooking oil. Some blades are 20 inches across, and could still be used. Since I don't disk anymore Not a great loss. They just weld up the 4 in hole. They are called waks or something like that. One guy left a another piece of metal when he took one blade. I usually just give blades away for cooking. One guy said he used his for cooking fish. Just don't take them. Stan
