I have several large fields of bet. 3 and 5 acres that require occasional mowing. In the past a local farmer would mow for hay, but with his herd reduced in size no longer has need for it. I do have a 4 ft. rotary mower that works well but takes forever and a day. Plus it's a rough cut, and leaves a lot of debris on top. I was thinking of getting a finish mower; something like 50-72" in size. The land mowed is debris/rock free, and I would never use a finish mower in an area that's questionable. Does this make any sense? Also, if a finish mower does make sense for my needs, is there a particular brand that anyone could suggest thats well regarded for performance and durability?
