The tank riders are fairly decent machines. They are not in the same ballpark as a Walker or something else you'd see very many of on the back of a landscaper's trailer. As a homeowner, you should do fine mechanically. Do you feel that your "hilly" terrain is a consideration?

agree with tom's take. would also add that such a machine will need inside storage, will burn a lot of fuel and require a substantial amount of ongoing maintenance. don't plan to just hop on it it , cut and hop off.
cutting round obstacles is relatively easy (slow on sharp turns), but long runs across open areas on less than smooth ground will demand your fulltime steering attention on the control sticks - both hands. If you are not aware of these things already, suggest you rent a similar machine first to find out if you really like how it handles.
