Agree with Wildernessbob. HANG the 30 gallon feeder instead of setting it on legs. Florida hogs will attack the legs making the feeder barrel fall. Then they throw the barrel in the air until the lid pops off to get to the corn. I modified a large feeder with two eye bolts close to the lid opposite each other, then I attached the eye bolts together inside the barrel with a turnbuckel so the eye bolts don't pinch the 2 sides of the plastic barrel together when lifted and screw attach only one section of the 4-part legs to the barrel to the 3 leg attachment points. These 3 legs are used to set the barrel and motor on the ground to refill the barrel when lowered. Then I tie a rope to each eye bolt forming a large V above the lid. Next tie a rope high between 2 trees to hold the barrel and attach a small U-bolt with a pulley to the center of this tree rope so the pulley doesn't slide on the tree rope. I then attach another rope to the barrel V, up through the pulley on the tree rope and to a boat trailer hand winch.

I attach the boat winch to one of the trees to raise and lower the barrel. Sometimes I use a 2nd winch on one end of the tree pulley rope to tighten the pulley rope. You can also buy a small 6.5 gallon bucket feeder to pull up and down without a boat winch, but it's harder to pull up in a tree then you might think.

Good luck and have fun outsmarting them. They are smarter than a deer.
