ABSTRACT:
In construction machines it quite common to utilize a plurality of control levers to manipulate a multitude of implements. It has often been a problem to quickly and accurately establish a connection between the control lever and the implement since the control lever is often quite some distance away from the mechanism that controls the implement. In many instances multiple personnel are required to properly assemble the various components. This leads to added expense and complexity of the assembly process. The present invention includes a restraint mechanism for a control lever that positively holds the control lever at a preselected location with respect to an established operational pattern. With the control lever locked in the preselected location, the connection of the control lever with the remaining components may be done in an extremely efficient and cost effective manner
