The ATV-Mounted PolyFence Wizard is designed to make temporary fence-building for cell grazing, fencing off hay lots, cross fencing, etc. an easy, one-person job. Mounted on the front of an ATV/utility vehicle, the Wizard consists of an angle-iron-frame tray that holds the tread-in posts and supplies, and tubing mounts for holding the polywire-dispensing spools. The complete unit also includes jumper wires, two spools, plus retrieval and spool-out attachments. To use, the operator sets the first post and attaches the wire from the dispensing spool then drives to where the next post is needed. Remaining in the vehicle, he sets that post with his left foot and attaches the wire to it. The process continues to the end of the fence run. To remove the fence, the operator uses a cordless drill motor on the take-up spool to reel in the wire.
