Hi Guys and Gals. First time zero turn mower owner. We moved into our 1/2 acre home late 2016. Bought a Gravely ZT-HD 48' in the spring of 2017 to take care our and next door neighbor yard. I have almost 60 hours on the mower now. It has been trouble free and does a very good job! I have very little experience prior to since we lived in Townhouse community before. So far i have changed engine oil twice, hopefully this mower will last many years ahead!
