This control cable transmits the operator's adjustment command from the cab-mounted controller to the metering slide on the fertilizer spreader. It connects the lever or actuator at the control end to the linkage that opens or closes the shut-off plate, regulating the flow rate of granulated material. A cable that stretches or binds will cause a lag between the control input and the actual slide position, leading to uneven application width. The cable assembly is manufactured to the original length and end-fitting geometry so that the full travel range of the control lever corresponds exactly to the full range of the metering slide.
