How to Repair a Self Propelled Lawn Mower

Self propelled lawn mowers are a great investment for homeowners. They can save time and money by cutting your lawn without any help from you. But, if you have an issue with your self propelled mower, it can be tricky to repair it on your own. This article will provide helpful tips on how to fix a self propelled lawn mower.

Fixing The Belt

There is a belt that is the main moving part of your self-propelled lawn mower. If you don’t know what this belt looks like, you can find it by opening the hood of your mower and looking for the motor.


The problem with this belt is that it can break easily. You need to take a look at it regularly to make sure that it hasn’t been damaged and replace it when necessary.

The belt on a self-propelled lawn mower is located at the back of the blade. It is important to change the belt when it wears out or becomes worn.

To replace it, unbuckle it from the pulley and unroll it as far as possible before removing. Then insert a new belt by connecting one end of the new belt to one end of the old belt and then connecting the other end to the other side of the old belt.

Fixing The Engine

The Engine of self-propelled lawn mower is a part of the lawn mower’s drive system. It is designed to move the engine, which in turn moves the lawnmower. The engine has a metal fan and a metal impeller that directly transfers power from the engine to propel the mower.

The most common problem that people face with their engines is that they have become noisy and have stopped moving.

The first thing to do when you experience a problem with your engine is to engage the blades in reverse and stop the mower. This allows you to remove the spark plug, which is located on top of a mesh.

The spark plug may also be located under a cap near the flywheel or under a metal cross-over tube that sits over the top of the first cylinder. Remove the spark plug and clean the area around it before you reinstall it.

Reinstall the spark plug as well as tighten it with a screwdriver. A torque wrench is recommended. You should never force the spark plug into place.

How to Change a Lawn Mower Spark Plug?

1. Obtain the spark plug that is to be replaced from your lawn mower. This allows you to remove the spark plug, which is located on top of a mesh.

The spark plug may also be located under a cap near the flywheel or under a metal cross-over tube that sits over the top of the first cylinder. Remove the spark plug and then install the new spark plug, ensuring that the old and new plugs are oriented correctly.

2. Remove the cap from a spark plug by turning it counterclockwise.

3. Install the new spark plug in two steps: first aligning the hex nut over one of two notches on top of a threaded stem with a knurled, cranked part and then tightening the hex nut onto that stem.

4. Ensure you align the notches on the threaded stem with the notches on top of a spark plug cap.

5. Install and tighten the cap onto the new spark plug, ensuring it is tight against one of two notches on top of a threaded stem.

6. Check for proper installation and torque by removing it from a cylinder head and rotating the spark plug to ensure all threads are engaging.

7. Apply a thin coat of clean engine oil around the thread pits of a new spark plug, then install it into an engine by turning it counterclockwise until it engages fully with one of two notches on top of a threaded stem.

8. Ensure that you torque the cap onto the threaded stem using a torque wrench. Torque specifications vary by manufacturer, but 20 ft-lb is not unusual for a spark plug cap.

This can be achieved by using the torque wrench to tighten the cap until you feel resistance, then release the torque and tighten it again two more times.

9. If your spark plug is a Champion® brand, it must be installed with its wire lock ring in place.

Fixing the Drive Cable

The drive cable of a self-propelled lawn mower is the part that connects the engine to the blade. It runs from the engine to the blade and provides power for it. If this cable breaks, you will need to replace it with a new one or fix it by yourself if you are handy with your hands.

Before you start, make sure that your lawn mower is turned off, unplugged from the power source, and all moving parts are still in place so that they don’t get damaged while working on them.

To replace a broken drive cable, you will need to remove the blade and engine first. You will also want to make sure that your lawn mower is on a level surface for this step. It should also be set up so that the blade is in neutral position and the Engine Housing Cover is facing up.

On most mowers, this can be accomplished by loosening the bolts that connect the blade to the engine housing. Once your new drive cable is installed, you should then reconnect everything together in reverse order.

Fixing the broken blades

Before attempting any fix, it is best to make sure that you have the right tools for the job.

You will need some basic tools such as a screwdriver and socket set to take care of most repairs on your self-propelled lawn mower.

If you have broken or bent blades on your self-propelled lawn mower, then it will be more cost effective to get replacement blades. However, if you are able to fix the broken and bent blades with a screwdriver and socket set, then you can save quite a bit of money by doing so.

First, gently remove the old blade from your self-propelled lawn mower. Then remove the broken blade from the shaft. Install the new blade on the shaft and then reinstall it in your self-propelled lawn mower.

Reassemble your self-propelled lawn mower and you are ready to go again!

Fixing the Wheels

Many people who own lawn mowers find that their performance becomes worse over time. This is due to the wheels on the mower, which often need to be tightened and replaced.

The wheels attached to your mower may feature a built-in gear or a modular gear assembly that helps them turn or receive commands from the engine.

Due to the materials used for self-propelled mower gears, a lot of times this may result in wear and tear over time. This can pose a problem if the mower is driven through areas that are thick with brush & vegetation.

Wheel replacement is a task that can be done by anyone. The hub cap of the wheel is detached to expose the wheel nut that keeps things together.

The removal of this nut can sometimes make the wheel fall off during use. To get around this, you’ll need to install a new drive wheel into the wheel shaft. Carefully and slowly tighten the nut back up to re-attach the wheel by holding it steady with your hand while turning.

Fixing The Batteries

Step One: Attach the battery terminal to the engine housing of your mower and using a bolt and nut, secure it in place by hand first, then tighten with a wrench.

Step Two: Attach the drive gear to the blade and attach the wire to the bolt and nut on another end.

Step Three: Connect the positive terminal of one battery with wire from the engine housing to the positive terminal of a second battery. Connect the negative terminal of the first battery to the ground/earth/negative post on the second battery (you can use a piece of wire).

Step Four: Connect the positive terminal of one battery with wire from the engine housing to the motor housing. Connect the negative terminal of the first battery to the ground/earth/negative post on the second battery (you can use a piece of wire).

Step Five: Connect the positive terminals of both batteries to the battery holder (if you are using only one, skip this step).

Step Six: Generally, it is a good idea to test your electrical system before connecting the motor. If you have made sure that you have two working batteries with a fully charged battery holder, then connect it up and make sure your electrical system is working.

If everything is good, then connect the motor to the starter on your mower (if applicable).

Step Seven: Connect the positive terminal of one battery to the positive terminal of the other battery and connect the negative terminal of one battery to the negative terminal of the other battery.

Step Eight: Connect one lead from your spark plug wire harness to a 6-volt spark plug (or distributor) and then connect another lead from your spark plug wire harness to your motor leads. If you are using a magnetic starter, connect one lead from the spark plug wire harness to the starter terminal and then connect another lead from your spark plug wire harness to your motor leads.

Step Nine: Turn on the ignition switch on an electric start mower or starter (if applicable) and make sure you are running in neutral. Your engine should now be turning over without the blades spinning.

Step Ten: Start your mower engine by rolling the throttle switch forward. The blades will now begin to spin and your engine will start running.
