A landing gear (10) is equipped with a mechanism (66) that isolates a hydraulic pitch trimmer (72) outside of the landing loop thereby eliminating the need for complex hydraulics normally associated with articulated landing gear designs equipped with pitch or trimmers or other articulating actuators. The mechanism comprises an articulated strut (68) connected between a bogie beam (18) and a shock strut cylinder (24) for controlling the pitch of the bogie beam, an over-center linkage (70) connected between the articulated strut and the shock strut cylinder, and an externally powered actuator (72) connected to the over-center linkage for moving the over-center linkage between the over-center locked position and other another position articulating the bogie beam from an end of take-off position to a stowage position, whereby the bogie beam can be properly angularly positioned relative to the shock strut for retraction into an aircraft landing gear bay.
