A two-speed control for dual hydrostatic motors, especially for self-propelled, skid-steered loaders having hydrostatic transmissions. Each motor has a rotating piston group and a swash plate inclinable in either of two positions of piston displacement for low or high speed output. A shift lever connects the swash plate control arms of the motors with a manual selector lever biased by an over-center spring mechanism to either the high or low speed position. The shift lever has a slide and guide connection with one swash plate control arm and pivotally connects to the other in an arrangement which automatically locks the swash plates in the proper attitude in either shifted position of the slide and guide connection corresponding to the low or high speed range. |
