Just wondering which lawn mower would be more worth the money, i own a lawn care service and i am preparing to purchase a new lawn mower to retire my aging fleet. The time cutter ss 4235 has a 42 inch deck on it and a 20 hp kawaski vtwin engine on it. Where i live its priced around $3400.00 and my other option is a jd x300 42 inch deck with a 18 hp kawasaki vtwin engine. the price for this one is $3000.00. what would be better?
