We're in the market for a fresh flail mower,mostly for farm tracks and outsides of fields. Quite like the look of the offset type which work behind or at the side of the tractor. Such as EF, EFD,EFDL,EFG,EFGL,EFH,TM,FM. There seems plenty to chose from. Anyone used these type of mowers ? or can you point me in right direction. Many thanks. See its perfect working:
