I'll have to look at the square footage on real green. You can do a 10-15k yard in about the same time as a 5k yard. Once this thing is open space it flys. I did time one yard which was 15,000ft2. It took 2 guys exactly 30 minutes to unload, aerate, broadcast, load, fill paper work, blow, and load up. We have yet to run 1 guy solo.
