What is the best method you have found to remove nails from a yard where new siding/construction has been done over an existing yard? I have one of my customers who just had new siding put on and there are nail and screws everywhere in the Rye Grass. I told her I could not cut within 15 feet of her house. She told me to do whatever I need to get the nails up and she would pay for it. Now I am not going to pick these things up one at a time. There are hundreds of them. These guys were the sloppiest workers.... Ideas? Oh yea.... one more thing. Some of the nails are ALUMINUM!
