Here is just one example of price vs profit, a brand new scag mower that I bought was 12k. There are guys mowing lawns for 35.00 with these. I bought a Zspray for 8500.00 and it has been the most profitable one man ride on piece of equipment ! I have been looking at aerators for a while and have not purchased yet, but will be at some point knowing what we make doing aerations. I don't think the price is outrageous in this day in age compared to ALOT of items in our trade.
