I am looking to purchase a mower for my home. I have used your units in my commercial business Z units and walk behinds. The purchase I want to make now is for my home which is slightly less than an acre smooth turf several trees and mild slopes. I am looking at a used Fast Trak what I think is a 20 hp Honda with a 52 deck (2006 +/-). I am not sure about the wheel motors/transmission in comparison to the newer units you are selling for home use today, the guy selling it wants just a few hundred less than I could purchase a new sport for. Are the wheel motors on this older unit better than the sport?
