Abstract
A flail mower assembly includes a deck having a shaft rotatably connected to the deck. A flail drum is connected to the shaft and is co-rotatable with the shaft. A plurality of flail blade assemblies is independently rotatably connected to the flail drum to provide two degrees of freedom-of-rotation of each of the plurality of flail blade assemblies independent of a direction of drum rotation. First and/or second electric motors are connected to the deck and rotatably connected to the shaft. The shaft is rotated by an energized one of the first or second electric motors or both energized simultaneously. A load connected to the first and second electric motors when the first and second electric motors are de-energized reduces a rotational velocity of the flail drum.
