This is the Spring for a new riding lawn mower. I cut too much grass with a bushhog behind my Kioti (while tearing up the yard); and too much walking behind a mower (for mid-60's). Do not have either smooth or stump free 4 acres (1.5 acres wooded). Ruined last riding mower hitting nearly invisible stumps. Now after 10 years, I think I know where the stumps are. Appears Ariens dealers sell machines with Kohler, while H.D. sells similar Ariens models with Briggs engines. Looking for advice for riding mower in the price range of $2,000. Who has had a mower that exceeded his expectations? Deep South Louisiana so no snow blower features needed. Thanks.
