Someone makes a feeder kit that does not use a "spinner" (no electric motor to burn out), but uses a timer to dump a gravity fed holder full of corn once or twice a day.
This feeder uses a "can" to hold the corn which is filled from a barrel by gravity. When the timer releases a catch the can dumps, then when empty it swings back into place and the catch holds it there until the timer releases it again (12 or 24 hours later).
With the projected price of corn this year my old barrel feeder may be too costly to keep full!
It hold 100# of corn, but there's no way to regulate the amount critters can eat, and I hate to spend my cash so the coons & squirrels can feast around the clock.
