A two lever, three function control apparatus for hydraulic control valves wherein a first control lever end is connected by a first cable to a first hydraulic valve operator, a link perpendicular to the first cable interconnects the first control lever and one leg of a bellcrank rotatable about on axis parallel to the first control lever. A second leg of the bellcrank disposed at right angles to the first leg is connected to a second cable parallel to the first cable which in turn connects to a second hydraulic operator. Fore-and-aft movement of the first control lever actuate only the first cable and hydraulic valve and transverse movement of the first control lever actuates only the second cable and hydraulic valve. To physically differentiate between the two function, the second bellcrank leg is twice the length of the first leg and a detent mechanism acting on the bellcrank hub is also provided. A second control lever is connected by a third cable to a third hydraulic control valve operator.
