Working Principle
The PTO system transfers mechanical power from the engine to auxiliary equipment like mowers, tillers, and pumps. The PTO control knob is mounted on the control lever via its 3/8-24 UNF thread. When the operator pulls, pushes, or turns the knob, it actuates the PTO control mechanism (usually a cable or linkage), engaging or disengaging the PTO clutch. This controls whether power is transmitted to the attached implement. The ergonomic knob ensures precise, effortless control during operation.
