It depends on how much lawn you have to mow. I had a 60" deck for many years and then bought a new JD tractor with a 54" deck to eventually replace my 420 with the 60" deck. After mowing a few times with the new tractor and the 54" deck I sold it because everything just seemed to be so slow with the smaller deck. It seemed like it took half again as long to mow. Stick with the biggest deck on whatever you get.
