Abstract
The connecting linkage between a control lever and a control valve that controls the operation or the manipulation of an implement of a construction machine is often complex and difficult to properly adjust. The present invention provides a restraint mechanism for the control lever 10 to maintain its position in a neutral condition with respect to the control valve. A first plate 42 is pivotally mounted to a base plate 22 on the console of the machine and is movable to a first position to engage the control lever 10 and establish a neutral position. A second plate 58 is utilized to selectively secure the position of the first plate with respect to the control lever while the proper connections and adjustments are made to the linkage arrangements connecting the control lever 10 and the control valve to synchronize their respective neutral positions.
