At $10 a yard you would need to sell 3,000 yards to recoup your 30k investment NOT including fuel, teeth, bearings, grease, and support machinery (read an additional $10-20k per year). The guy by us that tub grinds charges around 4k a day but has around $1,100 in over head a day, mostly fuel. It's something to think about. I would think realistically you are going to be in the 100k + range even for modest tub grinding.
