I think the DNR has enough to do, than try to govern the Wisconsin Gamefarms for safety. I have hunted on many Game-farms in WI and other states and NEVER FOUND THEM LAX ON SAFETY. I don't know of any Game-farms that let kids hunt with out a hunters safety card. There are many accidents on public land so I see no difference in safety.
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...
