ok, thanks to everyone for the input and advise on rider vs walker. I went today to purchase a 48 inch walkbehind and the dealer was out. He tried to sell me a 36 claiming that the 48 will only be a little faster and sells for 500 more. MY QUESTIONS IS WHICh ONE. Is the 48 that diffucult to operator becuase of its size and yes I do plan to put a velke on it.
