1. A flexible mower deck, comprising:
a first wing deck and a second wing deck pivotably attached to a first end and a second end of a center deck, each of the wing decks pivotable between a lowered mowing position and a raised transport position;
an electric blade motor on each of the first and second wing decks, each motor having a rotational speed that is set based on a sensed rotational speed of a plurality of belt driven blades under the center deck for mowing if the first and second wing decks are in the lowered mowing position; and
a height of cut mechanism on each of the first and second wing decks that raises and lowers the wing deck independently of a center deck lift mechanism by pivoting a four bar caster wheel level mechanism holding a caster wheel sleeve in front of the wing deck and pivoting a rear arm behind the wing deck.
