Here is a very handy and effective device I use to dispense corn with - but it could also be used to dispense any other seed or deer feed.
I had an old feeder that had a failed motor... I made a set of brackets to attach the feeder to the rear of the 4 wheeler - the lower one encircles the feeder and has a forward section with holes drilled in the outer ends of the bracket... these holes align with two 5/16" bolts that drilled into the rack of the 4 wheeler.
The upper bracket is an "L" shaped bracket on the outside of the drum and it has a circular shaped inner brace inside the drum to help distribute the weight when the drum is filled. The "L" bracket mates up to a bracket that is up high on the rear of the cargo box of the 4 wheeler.
When I want to use it, I just position the lower bracket over the 2 bolts and let it fall into place and then drop a pin through the upper "L" bracket and it - VOILA - it is mounted! It literally takes 15 seconds to install it.
I then route the pull rope over the cargo box, passing it through one of the lock holes and I make a quick knot in the rope so it can not fall down and drag or get backed over by the tire if I have to use reverse.
I fill the drum with corn - it holds about 150 pounds - and off I go.
When I get to where I want to distribute the corn, I simply drive along and pull the rope.... it opens the spring loaded door and the unit starts to dispense the corn!
I can dispense slowly or quickly by pulling the rope a little harder and/or driving faster or slower.
It works great and best of all - it was nearly free! The old drum, some scrap metal, 2 springs and a little bit of hardware... top it off with some "custom camo" paint (OK, I admit the paint was more for me than for the deer, heck... the 4 wheeler is YELLOW, after all!) and I was in business!
Try this for yourself if you have a need - I think you can do it with a lot of different containers and can be on the front or rear of the 4 wheeler.
It needs no batteries or wiring and is quick as a snap to use.
Please obey all game laws and regulations as it relates to deer hunting and baiting.
