I bought my aerator (113 hrs) and power rake from Home Depot, both are Blue Bird.
Both were well maintained and serviced so no concerns there.
The rental department also wanted to sell me a bunch of "spare" power rake parts.
It seems they had a rental unit they took apart so in the box was everything except the motor, including the bar and flail blades. I told them I really did not want it but they said give us a offer. So I said $20.00 and they said YES !!! Holy crap I got a great deal.
For both machines and parts I paid $2062.00 inc tax. Not bad. They paid for them selves in the first spring.
I would not hesitate to buy from Home Depot again.
