I am looking at several ZTRs for residental use only at present time. I have 7.2 acres of which I cut about 3.5 with mower and rest with a bushhog. It is mostly on a hill with trees and few large rocks that can't be removed. Nothing extremely steep. I currently have a lawn service cutting for me but they do NOT like to do residental apparently. They only came about once every 4 to six weeks last season to cut. They use Grasshopper 325/61 midmounts when they cut. They have no problems with my hills. My question is: will the Hustler Fasttrack in a 20/52 handle the hills or should I invest in a full size Z mower? I can get a 2003 Hustler Z 23 Kaw/60 for $6800.00 plus tax or a Grasshopper midmount 220/52 for $5995.00 plus tax. Please comment.
