Description
Overview:
The Spring Governor 16561-ZE7-020 is a genuine Honda OEM component for walk-behind petrol lawn mowers using Honda's GXV160-series engines. Made from durable spring steel, it links the governor arm to the throttle mechanism to regulate engine speed automatically under changing load. By maintaining stable RPM, it reduces hunting and surging, improves cut quality, and helps protect the engine from over-revving. This direct-replacement spring is suited to popular commercial and domestic models such as the HRD536 and HRH536 ranges. It is designed for a precise fit and correct tension profile, restoring reliable control of idle and top speed when the original spring has stretched, corroded, or failed.
Key Features:
- Genuine Honda part (OEM) for assured fit and performance
- Precisely calibrated tension for accurate engine speed control
- Helps prevent surging, hunting, and over-revving under load
- Durable spring steel construction for long service life
- Direct replacement for 16561-ZE7-020 with no modifications required
- Supports smooth idle and consistent blade speed for cleaner cuts
- Suitable for GXV160-equipped mowers used in domestic and commercial work
- Compact part that is straightforward to fit with basic hand tools
- Restores designed governor response after wear or corrosion of the old spring
Typical Applications:
Used on Honda HRD/HRH 53 cm lawn mowers fitted with GXV160 engines to maintain steady engine speed during mowing. Ideal when symptoms include fluctuating RPM, loss of top speed, poor idle stability, or inconsistent cutting performance after load changes such as wet or long grass.
