I'm new to the whole tractor spreader thing. I purchased one from my aunt last fall and have tried to use it, but I've got a lot to learn lol. My question is in the bottom of the drum is a spinner that should help bust clumps and feed things thru. When I planted the other day I noticed a lot of dust coming out of the spreader and some fodder flying around. Is that spinner grinding my seed up? I mixed wheat and oats and some of what I seen floating around looked like the outer part of the wheat seed.
