Many lawn mower owners feel the fatigue when they have to chug behind their mowing machine to clear the grass at their backyard or garden especially with a big lawn and not so powerful mower. The hot summer heat does not ease up the issue which has the lawn mower owners wish for a faster speed mowing machine.
These owners would be happy to note that it is possible to have their mower move faster to get their mowing job done. In fact, the mower could be converted into a racing machine if so desired with the right adjustments made to the engine. This would require some basic knowledge about mower engines and their safety components to tinker with them appropriately in speeding their function. However, such changes could also cause the engine to wear out faster especially at higher speeds than that recommended by the manufacturer.
1) Ensure that the lawn mower is shut off and cooled.
This would make the task safer when the engine is not operating. It is easy to get hurt with the engine still running even if it is stationary. This DIY task must take all necessary precautions to be well executed without getting injured.
2) Removing the Hood
The hood must be carefully removed from the lawn mower. This would allow the maximum airflow to reach the engine. The hood does the exact opposite by trapping hot air around the engine to cause it to be heated up and be less productive; much less faster.
3) Unscrew the bolts
There would be various bolts located near the base of the hood. These could be removed properly with the right sized wrench.
4) Inspecting the muffler
The muffler would be exposed when the hood is unveiled. There should not be any crack or hole in the muffler as its presence could reduce the back pressure engine; hence, the speed of the lawn mower is reduced.
If holes or cracks are present in the muffler, the best choice of action is to replace it if faster speed is really preferred.
5) Removing the engine governor
There is a flap located near the flywheel which is usually at the top of the engine. That piece is known as the engine governor. When the flywheel goes at high speeds, the flap tends to blow out to reduce the speed of the engine.
6) Uncover the Flywheel housing
In order to get the lawn mower to move at higher speeds than intended by the manufacturer, the flywheel housing must be unscrewed. This is easily done with the right sized wrench to work on the various bolts located around the flywheel perimeter. There is a housing cover on the engine’s top which must be removed.
7) Work on the Governor
At the side of the flywheel is the governor which requires some work. There is a bolt set in place to hold the governor flap to the frame of the engine. This holding bolt must be unscrewed along with the two springs that are found between the carburetor and the governor flap.
Next, the flywheel housing must be placed back on the engine top before bolting it in place again.
8) Fuel input
For more power, it is recommended to fill the engine gas tank with higher octane fuel which burns faster and cleaner to give faster speed. The 92-octane gasoline is the recommended option.
Lawn mower Components
The lawn mower comprises many components to become the functional machine one sees diligently on the lawn. These components should be familiar to the lawn mower owner if any DIY task is to be performed correctly.
These lawn mower components or parts are instrumental in speeding up the lawn mower when it is put to work on the lawn or backyard. Faster speeds are possible with the right twitching of these components in an apt manner.
However, the wrong twitch of these parts in the lawn mower could also prove detrimental to the power and functionality of the lawn mower. Hence, care must be exercised with sufficient knowledge in tinkering with the various component of the mower.
The various components in a lawn mower are put together inside the machine at their right places to ensure a functioning device that would perform its intended task; that is, cut grass. Each component has a role in ensuring the proper functionality of the entire mower. The specific role and functionality of each part of the mower is identified and tested in the factory to be approved for the consumer market.
There is a proper synergy among the different parts of the lawn mower to reduce the laborious work of cutting grass especially over a wide area. Every gardener, lawn mower or homeowner would want a functioning machine to simplify their lawn mowing tasks all the time.
Various components or parts of the lawn mower influence the speed of the lawn mower.
1) The Engine pulley
Every lawn mower has an engine; and a pulley comes along with it. Such mowers are known to be equipped with a common belt system on its engine. The speed of the mower could be adjusted by changing the pulley size.
Lawn mowers with a belt system usually are adorned with two pulleys; one of which is linked to the engine and the other is located near the end of the mower. This type of belt-driven mower is called the motor pulley mower where the pulley of the engine is secured on the crankshaft of the engine.
The speed of the mower could be increased when the size of these 2 pulleys are increased to offer more power to drive the mower.
2) The Engine governor
Another important mower component is the engine governor which holds an important role. It is a crucial component used to control the fuel flow in the gasoline engine system for a proper fuel supply to the engine.
The governor is the key component that establishes the higher limit in the speeds of the engine. With the attached spring, the engine governor determines the quantum of fuel to be supplied to the engine for an effective functioning.
Hence, lawn mower owners could adjust the governor spring to be shorter for faster speed. Furthermore, the spring could be removed in its entirety to gain even higher speeds.
3) The Air Filter
If the mower is not maintained properly, its speed could be affected. This is true particularly for the air filter inside the mower which is not cleaned out after use especially over winter. The power supply could be greatly reduced to impact the engine adversely. Hence, the mower performance is adversely affected with its speed.
An air filter which is clogged would slow down the mower speed. It is a simple task to change the clogged air filter to enjoy an extra thrust on mower speed. Usually the air filter could be found on the mower engine’s left side in the round compartment.
A simple cleaning of the air filter would do the trick unless the owner has no qualms in removing it completely to put in a new piece for better speed.
5) The Engine Oil
The oil provides the fuel to charge up the mower; hence, it is crucial to change the oil at the right time for a more efficient engine to run at higher speeds. Lawn mower owners need to identify the best type of engine oil which is most suitable to the engine. This would boost up the speed of the mower operation.
A better performance could be expected of the lawn mower when the best fuel keeps the engine in great condition to impact its operational speed.
6) The Spark Plug
Another mower component impacting its performance speed is the spark plug. This component is required to supply the spark in igniting the engine power through a mixture of fuel and air.
When the spark plug is faulty, the engine performance is affected; the speed of the lawn mower would be impacted adversely. This is a sign of the need to change the spark plug.
7) The Carburetor
The lawn mower carburetor component works to mix air with fuel in the right proportion for better engine operation. Any carburetor issue could affect the mower speed to generate slower performance.
8) The Mower Battery
A good electric lawn mower runs fast and well with a powerful battery. This happens with a new battery or when the battery is fully charged. Defective batteries will not offer the same power.
9) The Drive Belt
A faulty or worn out drive belt could slow down the mower speed.
By fine tuning and improving the functionality of these lawn mower parts, you can make your lawn mower run faster and get the mowing done in a jiffy.
