Description
Overview:
The Gearbox Pinion is a genuine Honda drive gear for professional walk‐behind mowers, manufactured to OEM specification (OEM No. 23411‐VB3‐801). Precision‐machined from high‐grade steel and heat‐treated for wear resistance, it transfers drive through the gearbox to keep cutting and self‐propel systems working smoothly under load. This pinion is engineered for the Honda HRH536 QXE Pro and HRD536K4 QXEH ranges, providing the correct fit and mesh with mating gears to maintain reliable performance. Built for frequent use and demanding conditions, it is a direct replacement that helps restore smooth power delivery, reduce gearbox noise caused by worn teeth, and extend service life when paired with clean oil and sound bearings.
