We have just bought a new house and i am trying to decide on the mower i need or want . I will be mowing .53 acre , i have thought about a 21'' push mower but i want to mow as fast as i can on my days off or before work . I am a firm believer in commercial mowers and that is what i want , i think the extra money up front more than pays for itself over time . I have been looking and wanting something from the Exmark line . I know the 21'' or the 26'' is probably all that i need but i was thinking if im going to spend that much money should i step up to a 32'' or 36'' walk behind . I have a gate to my back yard but the 36'' will fit no problem . Also if i do step up to a walk behind is the hydro worth the extra cost over the belt drive . I know having the reverse would be a big plus .Also is it worth stepping up to a floating deck over the fixed in this size . I know this is a lot to ask but i need help making up my mind . Thanks for any help you guys can give me .
