Abstract
A flexible mower deck includes a center deck with a plurality of belt driven pulleys for rotating a plurality of rotary cutting blades under the center deck. A wing deck is pivotably attached to each of the first and second ends. A motor on each wing deck rotates a rotary cutting blade by actuating a switch in an operator station to pivot each wing deck to a mowing position.
Claims17
A flexible mower deck, comprising:
- a center deck with a plurality of rotary cutting blades rotated by a belt engaging a driven pulley for each blade;
- a first wing deck and a second wing deck pivotably attached to a first end and a second end of the center deck, each of the wing decks pivotable between a lowered mowing position and a raised transport position;
- an electric motor mounted on each of the wing decks to rotate a rotary cutting blade under each of the wing decks;
- and
- a controller configured to 1) monitor a sensed rotational speed of the plurality of rotary cutting blades of the center deck and 2) set a rotational speed for each of the electric motors to match the sensed rotational speed;
- wherein the belt is operable to rotate the plurality of rotary cutting blades of the center deck while each wing deck is in either the mowing position or the transport position.

A flexible mower deck, comprising:
- a pair of electrical switches in an operator station of a zero turning radius mower to pivot a pair of wing decks between a mowing position and a transport position;
- an electric motor on each of the wing decks that rotates a rotary cutting blade if the wing deck is in a mowing position;
- a center deck positioned between the pair of wing decks having a plurality of rotary cutting blades that are rotated if the wing decks are in the mowing position or the transport position;
- and
- a controller configured to 1) monitor a sensed rotational speed of the plurality of rotary cutting blades of the center deck and 2) set a rotational speed for each of the electric motors to match the sensed rotational speed.
