From: Paul A. Waco , TexasSimple device. Unpack and ready to go. Attached to front end of loader on tractor and run across ground to pick up screws, pieces of metal . Do before mowing area. This area is where we scrap old machines for recycling!! Easy to dump collected metal in a wooden 8 tray we made to catch ball the scrap. Very powerful magnet and the release of the pieces could not be easier. Then brush bottom of frame to clean any dirt. I drilled holes in tractor bucket and put in eye bolts and used snap clips to attach bar, giving it a little swing is I hit something very large in the grass . Great product and will stop a lot of flats on tractor and lawnmower!!
