I had a Moultrie "EZ Load" and it was "OK" for about two years, then the motor casing leaked and the motor froze solid in DEC due to rain.
I then broke down and bought a Texas Hunter Products Trophy Feeder with "Ez Lift" system. It is expensive at close to $769 before shipping, but it is one hell of a feeder.

Premier 12-Volt TF300 Trophy Feeder 300 lb. Feed Capacity (corn)
Heavy Duty Galvanized Hopper Powder-coated Texas Hunter Green Finish
Built-in Galvanized Funnel
Lockable Lid & Door Protects Components
High Torque 12-Volt Motor Heavy-duty
Hanging Bracket 12-volt Rechargeable Battery
12-volt Solar Charger
Varmint Guard EZ Set Digital Timer (12-Volt) w/ 5-Year Limited Warranty


I’ve had it 3 years now and have been feeding 10 months per year on the same battery. At a couple pounds a day I usually go about 2.5 months between filling using a corn. Bean mix.
