I am just starting out for the most part next year and this is only part time for now. I mow a few lawns now and they range from 1/4 acre to 1 acre. I hope to add more for next year. There are no hills or steep slopes around where I live. I've only got one gated lawn. I didn't know if I should start out with a walkbehind or ztr. I was thinking ztr at the beginning, but the I started searching and thinking maybe I should get a good walkbehind. I've got a few choices so far. I thought about the Exmark Turf Tracer HP with the 19hp 48" deck, Exmark Lazer Z HP 50" deck, or the John Deere 727A 54" deck. I know two of those are riders but I've kind of got my mind set on the TT-HP if I get a walkbehind. I keep going back and forth in my head so I thought I would ask all you pros.
