Not to ask a dumb question, but I am assuming pine straw is just the needles off of pine trees. How do you bale it, and what is it used for? I have large pine trees on the back side of my house, and each fall the tree deposit 4 inches of pine needles onto the roof and gutters. I was just up on my roof a couple of days ago blowing the needles to the ground, and then I mow them up and get rid of them.
Thanks JekJr. I am familiar with baling hay but not pine needles! Is your baler similar to a hay baler? I'd be interested in seeing pics of both the finished bales and your equipment.

So do you hand load the needles into the baler? I don't see a scoop or rake that picks the needles off the ground and into the baler. Did you make the baler? It looks like a Harbor Freight trailer - lots of uses for those!
