Abstract
A flex wing rotary cutter includes wheel axles on each of the center and wing deck frames which are linked together for simultaneous rocking by a lift cylinder coupled between the center deck frame and the center axle. Each of the support wheels of the cutter is mounted to a spindle carried at the rear end of a rocker arm that is pivotally attached, at a location between its ends, to a rear location of a respective strut cantilevered from one or the other of the axles. An air spring is coupled between the strut and a forward end of the rocker arm and a shock absorber is coupled between the rocker arm and the strut at a location between the air spring and the connection of the rocker arm with the strut.
