KingTech 16HP Ride-on Mower Engine 450cc Vertical Shaft

The KingTech 16HP Vertical Shaft Engine brings 450cc of heavy-duty 4-stroke OHV power built for Australian ride-on mowers and outdoor equipment. Featuring a cast iron bore, electric start, and universal Honda and Briggs bolt pattern, this engine handles large properties and tough conditions without compromise. Reliable ignition, smooth throttle response, and fuel-efficient performance keep your mower running season after season.

Fitted with a transistorized magneto ignition system and centrifugal mechanical governor, this engine maintains steady RPM under load and fires up reliably even after months of storage. The 25.4mm vertical shaft and counterclockwise rotation suit standard mower drive setups, while the direct replacement design means you can swap it in for most 10-18HP engines without modifications.

Built for everyday Aussie dependability with an air-cooled single cylinder, 1.5L oil capacity, and compact 38kg frame that installs easily into most ride-on mower chassis. Backed by strong torque output and simple maintenance requirements, this power unit keeps your property looking sharp without constant upkeep.
