I run a relatively small business to help me pay for college. Now that fall is here i will be doing thatching and aerating. I will be purchasing a thatching attachment for my walker and really don't want to have to rent an aerator this year. The aerators for rent in my area are real back-breakers and are hard to be productive with. I am looking for an aerating solution suitable for doing half acre to one acre lots. I have a walker mower, husquavarna lawn tractor and 2 walk-behinds. I am hoping i can get an attachment to use on one of these machines. I saw the walker perfaerator but there is no way 3 grand for an aerator will pay off for my business. I have also seen the tow behind aerators for lawn tractors, but they look crappy and hard to maneuver on most properties i will be servicing. Budget wise i definitely can't be spending more than like 500 dollars for it to pay for itself this season given the competition in my area and my tight school schedule. Anyone have any ideas?
