I got a Woods DMH 6, paid $1550. It weighs. 890 lbs and has 20 notched blades spaced 7.5 inches apart. It cuts a 6 foot path and had gang adjustment angles of 0, 7, 14 and 21 degrees. The frame is 3x 3 tube steel with pins that go the frame and adjust easily. I really like it but do not consider it heavy duty. For my soil , sandy loam and clay loam it it great. I really like the "Everything Attachments" construction except for the angle adjustment mechanism. It features a threaded rod with handle for infinite adjustment which drives thru a "nut " welded on top of main frame. It could be fine but the "pin thru tube steel" is a superior design. I would be interested to know if anyone had had any failures of that welded nut. Other than that issue ( which may be fine) that unit seems heavy duty. It is about 2200 vs the. 1550 I paid. I am a structural Engineer and if I knew that joint was. "Designed" vs just built as "this seems like a cool idea", I would buy that unit.
