My house sits on 7 acres of which I mow about 3 acres of it every 5- 10 days depending on the time of year. I have a JD LT133 13hp 38" cut. Need something bigger and faster. I would also like to mow all 7 acres rather than just the 3. Not a lot of trees but planting more all the time. I have been looking at ZTR mowers such as the Kubota 21 hp diesel, Hustler Super Z, and a few others. Should I go with a commercial or residential mower and would diesel be going overboard. Are the ZTR mowers a good option for my needs or should I be looking at other options. Most of my neighbors have tractors with either a belly mower or a rear finish mower. Looking for opinions. Thanks for your time.
