I'm getting ready for the big spring push. One question I have is about tow behind aerators. We do a lot of spring aerations down here and just was wondering what the smallest size lots are that you guys use your tow behinds on? I did about 100 warm season turf aerations and about 75 cool season turf aerations last year with very little advertising. I plan to advertise heavily and double those numbers.(Aerations are much more profitable than mowing).The average size lawn around here is about 5000 sq. ft. I certainly don't want to invest in a tow behind if I'm only gonna use it on a handful of lawns. So what do you guys think? I look forward to reading your responses.
