A well-maintained lawn mower is the key to keeping your garden looking its best. But like any machine, its engine won’t last forever. If yours is struggling to perform, it may be time for a lawnmower engine replacement.
A failing lawn mower engine doesn’t have to mean buying a brand new machine. By recognising the signs of engine failure early and selecting the right replacement, you can keep your mower running smoothly for years to come. So, let’s explore the tell-tale signs your lawnmower engine needs replacing, and how to choose the right one for your needs.
Signs Your Lawn Mower Engine Needs Replacing
Difficulty starting
If your lawn mower takes multiple attempts to start or won’t start at all, the engine may be on its last legs. While issues like a faulty spark plug or stale fuel can cause starting problems, persistent trouble even after maintenance suggests a deeper engine problem.
Excessive smoke
A little smoke is normal, but if your mower is constantly emitting thick, white or black smoke, it could indicate burning oil, a cracked cylinder or poor fuel combustion. These are serious issues that often require an engine replacement.
Loss of power
If your lawnmower struggles to cut through grass, or stalls frequently, the engine might be losing compression. Over time, internal wear and tear can prevent the engine from delivering the power needed to keep your mower running efficiently.
Unusual noises
Loud knocking or grinding sounds coming from the engine often signal internal damage. These noises can indicate worn-out bearings, loose components or failing pistons - problems that can be expensive to repair.
Excessive oil consumption
If your lawn mower is burning through oil quickly despite regular top-ups, it could be a sign of engine wear. A failing engine may leak or burn oil inefficiently, leading to performance issues.
High repair costs
If you find yourself repeatedly repairing the engine, or if the cost of repairs exceeds half the price of a new engine, it’s time to consider a replacement. A new engine can extend your lawn mower’s lifespan without the ongoing hassle of breakdowns.
How to Choose the Right Replacement Engine
Identify your mower’s engine type
Before purchasing a replacement engine, check the specifications of your current one. Look for details like horsepower (HP), torque (Nm), displacement (cc) and fuel type (petrol or diesel) to ensure compatibility.
Consider the engine brand
Sticking to reputable brands ensures reliability and ease of maintenance. Always choose an engine from a trusted manufacturer to guarantee quality and longevity. At SPA Power Machinery, we stock various Kawasaki FS Series engines to keep your lawnmower performing at its best. Our Kawasaki engines are suitable as a replacement engine for SCAG, TORO, Ferris and Great Dane mowers.
Match the shaft size and orientation
The crankshaft diameter, length and orientation (vertical or horizontal) must match your existing mower engine. An incorrect fit could make installation impossible or affect mower performance.
Decide on a power level
Consider your lawn size and terrain when selecting engine power. If your current mower struggles with thick grass or hills, upgrading to a more powerful engine (with a higher HP or torque) may improve performance.
Look for fuel efficiency and emissions compliance
Modern engines are designed with fuel efficiency and lower emissions in mind. Look for models that meet UK environmental standards and offer improved fuel consumption.
Check for warranty and support
A good warranty provides peace of mind. Choose an engine with manufacturer support and availability of spare parts to ensure easy servicing and maintenance. Our Kawasaki engines come with a 3-year supplier warranty.
