Issues with ProMagnum feeder

I have two pro magnums that do the same thing. When the hopper has corn in it, the spinner plate will occasionally work or most of the time will turn a partial turn and stop. During the spin cycle, I can take a stick and help it go and it'll spin fine until the timer is up. When there's no corn in the hopper, all test spins are perfect. It's like the pressure from the feed is causing the spinner/motor to strain and not turn. The feed is clean and not clogging at all in the hole.

Does the funnel help with any of this or do you think there's an actual motor/spinner problem? I plan on sending them in for warranty replacement but I'm willing to bet that they send them back stating no problem found. The batteries are new and have tried two different sets of new batteries with the same results.

  • Definitely strange. What it sounds like is happening is the motor isn't able to over-come the torque required from a stall condition. The most common cause of this is the battery being dead and not being able to supply enough current. If you have any way of monitoring the battery voltage (like a voltmeter or something) it would be interesting to see what the voltage output of the battery is during the spin cycle - if it's dropping very low but then bouncing back up when the spin cycle is over that means that it's actually dead or close too it, but is providing a sort of false high when there is no load on it.

    Obviously I can't rule out a QA thing, but two in a row would be some serious back luck! I would definitely give Moultrie CS a call and tell them the problems you're having, because it absolutely shouldn't be doing that under normal operation.

  • I am having the same problem. I wonder if adding a second battery will increase the current enough to overcome the issue. Does anyone have any thoughts on 1 battery vs 2?

  • I too have this problem with my Pro Hunter I am on the third motor and all do the same thing. I have a solar charger and always have a fully charged battery display on the screen.
    KI wasted the entire deer season on this POS

  • I think I have solved the problem. Hope this will help others.
    After my last email I saw this video on You Tube so I decided to try it.I went out today and removed the feeder motor and in addition to bending the ears out so there is no 90 degree angles for the corn to wedge I ground off about 1/4 inch from the spinner plate shaft so it lowers the spinner plate giving even more clearance between the plate and the funnel.
    I made a saw cut on the corner of the longer ears of the spinner plate so I could bend them down also.
    I set all 6 times for it to cycle about a minute apart and ran the program twice..... no stalls threw corn every time.

  • I have the 30 gallon feeder and am having the same problems. I had already bought the better spinner plate, which has flared ends so that nothing can get caught, but when the feeding time comes, nothing happens. The plate spins freely when I turn it manually, and works so well that corn practically falls out when you breathe near it. The battery is new, shows a full charge, but the only thing I can think of doing is replacing the battery. It came from an old landmark garden center, and maybe they were new but old. I'll post again after I install a new battery.
