For next year I'm wanting to target the smaller yards. I want to be able to get in and out in 30 minutes or less. I'm tired of the headache and hassle of the bigger yards. So, for everyone w/ smaller yards which do you prefer: ZTR or Walk Behind? And why? I'm kinda leaning towards the Walk Behind b/c it may be a little easier getting into tighter places. Also, it won't leave as much of a track. What do you all think?
