I bought a used New Holland box spreader with single horizontal beater for spring cleanup of the area around the winter hay feeders.  It works very well in that type material as long as I don't fill it above the beater centerline.  if filled higher it clumps.

It would be better to have two horizontal beaters and fill higher, or the vertical beaters. However for the price and the little I use it the single horizontal beater NH works fine. Just have to make a couple extra trips a year. Good luck .
