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!!
