ABSTRACT:
A skid-steer loader having transversely spaced wheel assemblies driven by individually operable drive mechanisms having spaced apart independently mounted hydrostatic motors is disclosed wherein a speed shifter linkage interconnects the hydrostatic motor cam shafts to affect a simultaneous shifting of both motors from one speed to another. A floatingly mounted cross shaft is threadably engaged with trunnions pivotally mounted in pintle arms fastened to the hydraulic motor cam plate shafts. Rotation of the cross shaft is affected through manipulation of a control lever engageable with adjustable stops to permit a quick and convenient adjustment of high and low speed operating positions. A frictional clamping of the linkage between the control lever and a sprocket for rotating the cross shaft provides an easy initial positioning of the control lever and permits a still greater range of adjustment of the nominal operating positions for maximum operator comfort.
