Why this coupler

  • Pioneer AG interchange — which means it couples with the widely used Pioneer 4000 agricultural coupler standard found on tractors and farm equipment.
  • Steel ball check valves — which means dependable shut-off in heavy-duty hydraulic service within rated pressures.
  • Ball-locking mechanism — which means the mating halves are held securely together under load and vibration.
  • Induction-hardened, solid bar stock — which means critical parts resist wear for long service life in abrasive environments.
  • Proven heavy-duty design — which means reliability on construction, ag, oil-field, and steel-mill equipment.
