Ok, as I promised in Tree Machine email thread, I have pictures of his winder upper for the throwball. He gave it to me at the last Columbus TCI Expo, while he was still recovering from that horrific stump grinder accident. I have been using a throwball quite a bit more, previously I hated to stuff the line back in the bag. This one makes rewinding the line very easy. It is currently loaded with 180 ft. of Zing It.
