Abstract
A control lever assembly for controlled reciprocation of an operating member which may be a Bowden cable for regulating the flow rate of a pump supplying a hydraulic motor in a hydrostatic transmission. In addition to the usual pivotally mounted control lever, an intermediate lever is pivotally connected between the control lever and the operating member. The intermediate lever is received in a sleeve member which is pivotally mounted about a fixed axis spaced from the fixed axis about which the control lever pivots. The sensitivity of the control lever assembly is thus made smoother and more gradual proximate to the neutral or dead center position of the assembly.
