I am buying a couple new pieces of equipment, one of which is an aerator. i have looked at a lot of different models and prices. i rented and used a bluebird before and i hated it. it was a hard machine to use and just hard on your body. i am either making a decion on buying the ryan lawnaire V(26.5") or the ryan lawnaire 28. there is only an $800 dollar difference in price, which is not a problem. i just want to know which one will be easier on my employees, do the best job, and be the most efficient.
