we are adding lawncare next spring and have found a dixon 5021 commercial that is used but it is in decent shape. is this a reliable mower or would i be better off to hold off another season and buy a new one with a warranty.i am leaning toward purchasing it. which i can easily pay it off in 90 days so i dont have a payment for our first season.i have heard bad feedback about dixon. that is my only concern.some say dixon commercial is just an over priced residential mower. thanks for your input.
