Because the person I talked to about the Ariens lawn mower I have from your company did not answer one question I asked her she was not informed of all she needs to learn product information I cannot believe that you even have people like that answering the phone you can't even answer a basic simple question and also I am disgusted with my lawn mower I bought that lawnmower thing it was a very good brand and make great reviews my lawnmower has been nothing but a lemon I've had nothing but trouble with it on and off since the day I got it it's not been reliable when I need it the most States had to go into the shop I should have went out and bought a Skaggs or a Dixie Chopper I regret that I did not do it now thank you very much Mark.
