Frequently Asked Questions
What's a typical feed amount per cycle?
Most timer-based spin feeders dispense 1-4 lbs per cycle depending on the throw setting and motor duration.
Why include a waste factor?
Wind, birds, and rodents cause spillage and loss, so actual corn depletion is usually higher than the programmed dispense amount alone.
How often should deer feeders be run per day?
Most hunters run feeders 1-3 times daily, often at dawn and dusk to match deer feeding patterns.
