well i just got back in the house the other day after getting into an argument b/c my father seems to believe there is absolutely no difference between residential and commercial mowers and will not let me ditch my POS Timecutter. I had put my Toro Timecutter Z (which I STRONGLY recommend nobody who mows commercially to buy) in the newspaper in the classifieds, without mentioning it to parents. So i am not home when a guy calls about it and leaves a message on the answering machine. Dad comes home and listens to the messages and when I tried to explain why I was doing it (so I can get an Exmark w/b next season) he refuses to listen to any of my perspective and then asks me how mush extra i would be spending. I say $1000. he says no way and claims I have a car to pay for and can not get a real machine. He forget the fact that with the extra 10+ customers I will have next year, I would be able to earn that 1000 back in about a month. So I told him he will pay for every replacement part I will buy and I will charge him by the hour for all of the time I waste maintaining it. Is there any advice I can get from anybody to convince him?
