I am a part-timer and I only do residentual lawns in my neighborhood. I was looking at the Exmark CT 19hp. Still undecided if I will go with the 48" or 52". Keep in mind I'm only looking to get a max of 20 lawns. Do you pros out there think this piece of equipment will work for that. All lawns are 1/2 acre or less. I am demoing the 48" 19hp this week. I'll let you all know how that goes. Thanks for any input.
