Any NEW grownd driven speader will be POOR at best. Any OLD ground driven (1950's or older) will work GOOD at worst. The older ones can adjust their unload speed to a point that the spread will almost cover the ground totally. If you only have a few critters oone of these older ground drives would work well, but if you have more critters get a bigger PTO type. Also- here in NY the ground drive does slip sometimes in the winter. Ice or very heavy snow can do it, but just put a tire chain on the spreader and you'll never have a problem. I have a newer (80's) PTO spreader and an old (40's) ground driven spreader. The old one has 5 times more use than the new one, just since I've had them, and that old girl has never, never let me down once! The newer one I've had to replace chains, bearings, ratchet locks, etc on. Both are New Idea, as good as were ever made. That old girl i got for $100. More than that was put into the newer one just last year. Mike
