Its really simple to make a crank up feeder. Like LandPirate said pipe of the appropriate length a boat winch and a pulley from the hardware store. We also run a small chain around the legs about 1/2 way up to keep the legs from spreading out. Immagine never having to climb a ladder with feed, or worry about hogs or cattle tearing up your feeder again! Crank ups are all we use.
