Patent ID: 6860093

Claim:
A mower comprising: a main support frame adapted for supported connection to one end of a self propelled support vehicle having a predetermined direction of forward travel including a first subframe having a first pair of vertically spaced parallel guide members extending laterally in relation to said direction of forward travel, a second subframe including a second pair of parallel guide members supported by said first pair of guide members for predetermined lateral movement of said second subframe and a first linear power actuator interconnected between said first and second subframes operable to adjust the lateral position of said second subframe relative to said first subframe, an inverted U shaped frame pivotally connected to and extending laterally from said second subframe including a laterally inward upright leg, a laterally outward upright leg, and a horizontally extending beam having one of its ends rigidly secured to the upper end of said laterally outward leg and having its other end pivotally connected to the upper end of said laterally inward leg, said beam and laterally outward leg being vertically swingable from a mowing position in which said laterally outward leg is upright to an overhead position in which said beam and laterally outward leg are above said laterally inward leg, a rotary cutter head mounted on the lower end of each of said upright legs, a second linear power actuator interconnected between said laterally inward leg and said beam operable to vertically swing said beam to said overhead position, and a third linear power actuator interconnected between said second subframe and said laterally inward leg, said power actuator being operable to pivot said inverted U-shaped frame to an inoperative transport position.
