ABSTRACT A rotary mower having a central section and extension wings or end sections relatively pivotably movable upwardly and downwardly with respect to the central section. Each of the sections includes a plurality of cutting units mounted for rotation about vertical axis to provide a horizontal cutting plane across the width of the mower when the exten- sion wings are in a lower or mowing position. Each cutting unit is carried on a horizontally disposed pneumatic tire wheel. An external drive rotates one of the tire wheels. The other tire wheels are mounted in frictional circumferen- tial engagement with each other and the driven tire wheel so that all wheels are driven in the mowing position. When either of the extension wings is pivotally raised to a posi- tion greater than approximately 30° relative to the center section, its tire wheels are moved out of frictional engage- ment with the tire wheels of the center section so that its cutting units are rendered inoperable. The mower has an adjustable cutting height and is capable of being tilted upwardly as a unit to a vertical position so as to expose all cutting units and tire wheels for maintenance purposes.
