You could always "Outsource" your aeration work to some other lawn care company that has a $10,000 aerator. Then you don't have to worry about spending the money.
Sounds like a win, win situation!!!
You're not out the $10,000, the work is getting done, and now you have extra capital spend in your business. Problem solved.
