Abstract: A mowing apparatus with multiple articulating cutting decks includes a support for the cutting blades which is attached at a first side to the mower to pivot about a horizontal axis, and is carried by a rocker arm at an opposing second side. The rocker arm has ground support wheels at its opposing ends and is coupled to the second side of the support by linkage that is adjustable to vary the position of the support member relative to the rocker arm and to vary the height of the cutting blade from ground.

Abstract: A mowing apparatus with multiple articulating cutting decks includes a pair of side cutting decks attached to a center cutting deck. The side decks are pivotally attached to the center deck and pivot about axes which lie in the planes defined by rotation of the respective cutting blades. The cutting blades are driven by pulleys and belts. Proper tension in each side drive belt is maintained during pivoting of the corresponding side deck by an assembly comprising a pair of idler pulleys rotatably mounted on a pivotally attached pulley arm which is biased in the direction which increases tension on the belt.

Abstract: A mowing apparatus with multiple articulating cutting decks includes a support for the cutting blades which is pivotally attached at one end to the mower and is carried by a rocker arm at the other end. The rocker arm is rotatably attached to the support and has wheels at the front and back ends for supporting the rocker arm on the ground. The vertical position of the wheels relative to the rocker arm is variable.
