Question

What is the best way to get a lot of nails out of the grass?

Answer 1

all the answers are good and in my opinion the only ones.

Answer 2

I don’t know the name of the piece of equipment but contractors use it to remove nails from construction sites.  It has two wheels on both sides of it and a long magnet in between the wheels.  The magnet is about 3 inches wide and 2 feet long.  I think it’s called a magnetic nail remover.  

Answer 3

A strong magnet, inserted into a can, or sock. (so you can easily release the grip to dump off the nails)

If the nails are aluminum I'd use a shop vac.

Answer 4

A magnet maybe?

Answer 5

big magnet or metel detector  

Answer 6

A big magnet.  Wal Mart has one you tie to a rope for about $10.
