I think what he is talking about is a Gandy Drop Spreader or something similar to that type spreader. Several companies have made these through the years including Deere. You can get one at a farm auction for about $2 but they go for $1k on Craigslist and I'm not on Facebook but I am sure you might see one there. You can also look on TractorHouse or Fastline. Sounds like the St. Clair Co-Op might have new units you can purchase.

They certainly work. They don't hold a whole lot in terms of pounds of lime at a time.... so if your lime pile is far away you'll make a lot of trips to spread a couple 1,000lbs at 500 lbs a tote but that's not real that bad if you don't mind a little work..
