I'm looking to get a 3pt spreader to help with my driveway and my parents in the winter. Together it's over a mile to take care of, with the usual western pa hills and turns in the driveways. We each have an outside wood burner so we have a ton of coal and wood ash that we throw in 55 gallon drums to keep dry and currently use on my parents driveway. It's only a couple hundred feet long so we spread by hand. Mine being almost a mile long, I'm looking to pickup a 3 pt spreader but I know I need to crush the ashes so there able to run through. Any ideas on what to use to crush them? Or something I could use on the back of the tractor to spread them as is? I thought about making a manure spreader type design to spread them as is but if I can buy something reasonable I'd rather go that route.
