Pull-Only Control Cable Assembly With Red PTO Knob
Product Description：
A control cable with a red PTO (Power Take-Off) knob is a dedicated mechanical pull-type control assembly widely fitted on agricultural and off-highway machinery to engage or disengage the power take-off system. The high-visibility red knob acts as a distinct visual marker for operators to quickly find and manipulate the PTO control. This mechanical cable assembly converts manual pulling force into linear motion to activate or deactivate the PTO unit. It adopts heavy-duty flexible conduit and high-strength inner steel wire, suitable for installation on tractors, harvesters, farm implements and construction machinery. The red knob delivers clear visual warning, helping operators make fast, correct operations during daily field work. It supports custom length, stroke and mounting thread sizes to fit OEM and aftermarket replacement requirements for different equipment models.

Working Principle
This PTO pull-only control cable transmits manual pulling force through inner steel wire. The outer conduit is fixed firmly to machine housing by dual locking nuts. When the operator pulls the red PTO knob, inner steel wire moves linearly and transfers pulling force to the PTO linkage mechanism, to complete power take-off engagement or disengagement. An external return spring on machinery side is required to reset the knob and inner wire back to original position once released.
