I have been contemplating buying a bed edger for most of the season and still have not found the answer. So far for the season, I have rented one 7 times for a half day and it has cost me $40/ea. So for the season I have shelled out approz $280 for the little machine and made a little over $1000. This has left me a profit $720 for a few hours work and is usually priced much higher than anything else. I believe one mulch job that I did I ran it for about an hour and made over $200, would have to open Quickbooks to get exact amount. Now, If I were to own one, I would of course have $2100 or so dollars out of pocket but I would of course never have to rent again thus a time or money savings factor is added in and next year I will probably use it an estimated 12-18 times is my guess. Now, usually equipment purchases are a no brainer, but this one I just can't make sense out of one way or the other.
