Spreading some half composted manure with a International Harvester model 200 ground drive spreader. The floor chain is size S and is worn out so we don't haul full loads or it will break. I had to replace the wooden floor and fix a few other things when we got it but it works fine now. With this loose fluffy half compost manure a lot of it falls off the end of the spreader before it can get flung by the beaters but in more pack type manure it does a really good job of spreading.
