All the 3 point bar mowers I have seen are to run with a clockwise PTO shaft. Why can they not br run with a counter clockwise PTO? The cycle would still move back and forth. Don't think a wobble box direction of rotation would make any difference.. Reason for asking is my Sotah Bevaer CUT has a 2 speed PTO but it runs counter clockwise. Requires a revers-er attachment for most PTO drive equipment. But would it make a difference on an older bar mower ? ?
