Our FS Series engines are powerful, reliable and resilient. They offer long-term, high-level commercial performance and can be steadfastly trusted to power your mower day in, day out.
Automatically releasing cylinder pressure during start-up reduces the force required to start the engine.
This reduces strain on the engine starter and makes for reliable starts every time, regardless of engine temperature – so you can be sure your machinery is ready to work when you are.
Dual element air filtration through foam and paper elements traps airborne particles and contaminants before they reach the combustion chamber, even in the harshest conditions. This high particle capture capability keeps engine performance at optimum levels and means less maintenance over time.
A hemispherical shaped cylinder head is designed to reduce heat loss and improve the movement of air and fuel inside the combustion chamber.
Your engine is made more efficient as less fuel is needed, and more powerful as the effectiveness of the combustion process is improved.
Twin oil feeds provide high-pressure lubrication and cooling, vital for reducing friction and ensuring longevity. The system protects components, even at maximum performance levels, keeping your engine working reliably for longer.
A rotating metal screen chops larger cuttings into fine debris, preventing grass build-up on the cooling fins. This protects engine cooling for reliable performance, keeping your engine running smoothly and efficiently.
Easy access clean-out ports located under the engine housing give a clear view of the cylinder’s cooling system, making inspections and cleaning quick and hassle-free. *Dependent on engine specification.
Engine life is extended and internal components protected by a heavy-duty oil pump designed to handle commercial-level workloads. It circulates engine oil under pressure to lubricate the components and assist with engine cooling.
Robust materials make the difference for a durable engine. The high-speed sliding of piston rings inside an engine cylinder causes high temperatures, high pressure and abrasion: cast iron is able to withstand this exceptionally well, prolonging engine life.
Crankcases and cylinder heads are high-pressure die cast using automotive grade aluminium, providing durability while remaining lightweight.
A simplified mechanism that makes valve clearance adjustments easier for quicker servicing. These adjustments are essential in maintaining maximum power delivery and engine efficiency.
FS Series engines utilise a 90-degree V-Twin configuration to achieve perfect primary balance. The design generates less vibration from piston movement, improving both the power and durability of the engine.
The carburetor is vented internally to keep your engine efficient with reduced contaminants, while the fuel shut-off solenoid ensures smoother operation.
"When I think of Kawasaki, I think power and reliability. If you buy a Kawasaki-powered machine it will last. They never let me down."Paul Griffin, Paul’s Garden Services and Handyman
We offer a three-year, unlimited hours warranty for commercial and private use on all of our FS Series engines. Because, at Kawasaki Engines, we know that a reliable mower requires an engine that can power through the rough patches, we provide a warranty that gives you the confidence to do so. We’re so sure of the quality and dependability of our engines that you can enjoy three years of complete confidence in your engine performance, no matter how many punishing hours of work you put your new mower through.
