Vertical Shaft Engines


The Honda GXV630 with its powerful twin engines is used in a variety of applications from lawncare equipment to small vehicles and tractors.


The OHV design enhances combustion efficiency and ensures an optimal power transfer.

Honda’s Variable Timing Digital CDI ignition allows optimal ignition timing based on engine speed. The result is excellent starting, high power output, reduced fuel consumption, and outstanding emissions performance. An engine rev limiter is also incorporated to prevent over-revving.


The lubrication system uses a high capacity pump with discrete chambers. This facilitates consistent oil delivery to the flywheel, PTO, and connecting-rod bearings. The result: reduced friction, extended engine life and less mechanical engine noise.
