Ok, I am really confused. I read so much about the home made striping kits and how great they work....so i bought some 3/8" chain, a pre-drilled angle iron piece, and attached 6 links. Did not want to make any longer before i knew it really worked. Set the height at 4", cut my lawn, and was very, very dissapointed when nothing happened. I know that 6 links (about 6"-7") wide is not enough, but still.....not even a hair difference. Here are the pictures.
