I am new to this website and could use some expert advice. I am a homeowner with 2 1/2 acres and lots of trees and landscaping. I am looking for a ZTR with a 48" cut. I have narrowed it down to two models based on dealer support in my area and the recommendation of a friend that is a profeesional landscaper. The models are the Exmark Lazer Z CT with the 19hp Kawasaki engine or the Husqvarna IZ4818 with the 18hp Kawasaki. Your input on durability and quality of cut would be greatly appreciated. Thanks!
