I own a 2 year old aerator and I'm putting about 25 hours a week on it this time a year. My scheduling is pretty tight with one employee scheduled 4 days a week with 6 ish lawns a day. Minor breakdowns are killing me. It broke a belt = 2.5 hours to take it in and get repaired. The chain broke = down for 24 hours while a new one was ordered and so on. My dilemma is do I buy a backup ( used aerators are impossible to find ) new $2400, or do I rent with every breakdown over 2 hours??????
