WILDFIRE - I have a New Idea 101 that is made for spreading ag lime. It is a 9 footer I believe, and if you figure out how much it will cost to split it into 2 functioning units, it may work out you can have a 4 or 5 footer for the cost of the split and build.
Our coop has an EZ Flo we paid $300 for on craigslist WTB ad, but I could use a smaller unit for harder to reach areas.
If you are interested just get some input here on what the cost would.
