  • Clean Out the Air Filters Properly.
  • Take Care of the Moving Levers.
  • Tighten The Belts and Wheel Hubs.
  • Grease The Joints.
  • Sharpen The Blades.
  • Drain The Fuel.
  • Clean Out Any Debris.

You Need to Clean the Spark Plug

Spark plug is undeniably the most important part of the lawn mower as it is responsible for igniting the fuel in the engine, which results in the spinning of blades.

Before you start servicing your lawn mower, you need to look at the spark plug and make sure it is properly cleaned and is in a pristine condition.  Before you undertake the process of cleaning your spark plug, you need to make sure that the plug is properly disconnected, and the engine doesn’t ignite when you clean the spark plugs.

Once you have properly disconnected the engine from the spark plug, you can then begin to clean your spark plug. Check the manufacturer’s manual to make sure that the gap between the spark plug and the engine fuel is as recommended.

Remove the spark plug from the engine and thoroughly clean it with a wet cloth. Once the spark plug is cleaned, let it dry before inserting it back into the engine. You also need to remember not to overtighten the spark plug when you are replacing it or inserting it back into the engine as this can easily and accidentally close the air gap between the spark plug and the engine.

Elimination of the air gap between the spark plug and the fuel will hinder the process of ignition and cause problems.

You Need to Drain Gasoline

Another important thing that you need to remember is to completely dry up your lawn mower at the end of every cutting season and make sure there is no gasoline left inside the tank.

You need to take care of the residual fuel left in the tank and keep your lawn mower running as long as possible in order to drain it. The majority of fuel cans have a shelf life of around 30 days, and using stale fuel to start up your engine can result in damage to your lawn mower.

Therefore, you need to make sure that you have drained every drop of fuel from your tank and cleaned the engine with a wet cloth.

Take Care of the Accumulated Debris

One of the most important tips when servicing your lawn mower is to clean out any debris from the engine and other places of a lawn mower. One of the most important places to check underneath the cutting deck to make sure that there is no residual debris or dust.

Moreover, you also have to take a look around air inlets and motor and make sure that there is no debris that can cause your lawn mower to overheat during the next cutting session. If you want your lawn mower to function as long as its advertised lifespan, you need to make sure that you properly clean out any debris from underneath the cutting deck and from around the air inlets.

Remember when cleaning out the debris that wet and moist grass is easier to remove then dry grass. Therefore, you need to clean your lawn mower from any form of debris after the cutting session, and you should not wait for weeks to remove the grass from blades and air inlets.

You also need to make sure to wear personal protective gloves around the blades and take care of your eyes as well with the help of protective goggles. Moreover, it is usually recommended that people take the spark plug out so there’s no risk of starting the lawn mower with your hand near the blade.

You Need to Check Bolts and Nuts.

Lawn mowers are designed so that the blades keep running extremely fast in order to cut any excessive grass from your front yard. This fast motion can result in loose bolts and wheels, and you need to make sure that all the bolts and wheels are tightened when servicing your lawn mower.

If any bolts are loose, the blades can come off and can seriously result in severe injuries. It is better to make sure that all the bolts nut and wheels are in place when you are servicing the lawn mower. Professionals recommend tightening the bolts and wheels during every session, but not to overtighten the bolts, as this can also result in issues with the lawn mower.

If your lawn mower is wobbling irregularly more than usual, you need to take a look at the axle nut, which may either need replacement or adjustment. It can also be an issue with the wheel itself, and this is why you need to take a look at all the nuts and bolts in your lawn mower during your next servicing session.

You need to Sharpen the Blades.

You can keep using your lawn mower to keep your garden tidy and clean, but if the blades are blunt, it will have less than a minimal impact on your grass. You will end up wasting a lot of fuel without any results.

Therefore, during every servicing session, you need to make sure to sharpen the blades of a lawn mower and keep them in a healthy condition. In order to sharpen your blades, you need to safely remove the blades from their position and take it to your local lawn mower dealer for proper sharpening. Once again, professionals recommend that the spark plug be removed for safety.

You can also sharpen the blades by yourself with the help of a file, but you need to make sure that you are wearing protective gloves and goggles. However, it is recommended that you take the blades to a professional lawn mower service center since they will understand how to properly sharpen the blades at the natural angle of the cutting blade.

These professionals can also make the blade evenly weighted so that these blades don’t come off or wobble during the next cutting season.

Take a Look at The Throttle Cable Adjustment

If you have a lawn mower that still uses a throttle cable to ignite the fuel, you need to make sure that the throttle cable is properly adjusted and clean of all debris.

  • You need to make sure that the throttle is properly connected to the butterfly choke inside so that it can properly ignite the fuel to spin the blades.
  • In order to service the throttle cable, you need to take off the air filters and ask someone to operate the throttle lever while you are taking a look at the valve.
  • Just a little behind their filters, you will find the butterfly valve that is supposed to be properly connected to the throttle cable. This basically serves as the lawn mower’s choking mechanism that is used when you use a throttle cable to start the lawn mower.
  • When you are not using a throttle cable, this butterfly valve should be closed all the way.
  • When your friend or somebody moves the throttle lever, you need to make sure that the butterfly valve opens up slowly to accommodate the throttle cable.
  • When this throttle lever is moved to full speed, you should also notice a butterfly valve that should also be open all the way.
  • Otherwise, this could indicate a problem with your throttle cable. If there are any problems with the throttle cable, you need to loosen the cable screw and re-tighten the screw in order to adjust the throttle cable properly.

You Need to Check the Drive Belt

Another important thing when servicing your lawn mower is to make sure that the drive belt is properly connected to the rest of the engine and is not loose.

Moreover, you also need to make sure that there is no grass or debris accumulated under the belt guard. If the drive belt and the belt guard are filled with grass, the belt may come off at any time and get stuck in the blade. It will then be shredded into pieces.

Therefore, if you want to make sure that you do not have to pay any additional money on replacing your drive belt, you need to remove the belt guard and check if it is filled with debris. You can easily remove the belt guard cover that is attached to the lawn mower with screws and take a look at the belt itself.

Once you have removed the belt guard, you can take any fluid or oil and clean the belt as well as the belt guard to make sure that it is properly cleaned and ready for the next cutting session.

If the belt is old, worn and cracked like in the photo below, you should definitly get a new one.

You Need to Inspect the Transmission Box

Lastly, you also need to check the transmission box and make sure that it is free from any grass or debris.  If the transmission box is filled with accumulated dirt or debris, it will slowly start causing problems for you when you use the lawn mower. The transmission box acts as the catalyst for controlling the movements of the lawn mower.

Lift the grass box deflector up and remove the square plastic part from the back of your lawn mower in order to get to the transmission box. You can use a long piece of metal or wood to keep the grass box deflector out of the way and check the transmission box manually to clean it from any residual debris or dust.
