Hey guys, Wanting some opinions on this one..... I am debating rental vs. purchase of an aerator and power rake for the 2013 season. When I used to live in the south and was in business with my dad we used a core aerator quite a bit and never de-thatched lawns. I'm up here in Wyoming now dealing with cool season grasses and I'm sure not all my accounts will want their lawns thatched and aerated but if I found a couple low hour machines for a good price I would consider investing in them just to avoid the hassles of equipment rental. I probably wouldn't use them more than twice per year (spring and fall) on 15-20 primarily residential accounts. Any thoughts??
