What You'll Learn
Disconnect the spark plug
Disconnecting the spark plug is a crucial safety step when removing or working on a lawn mower's electric clutch. It prevents accidental ignition and activation during the removal process.
Before beginning any work on the electric clutch or any other part of the mower, locate and disconnect the spark plug. This is usually located near the engine or in a compartment on the mower's frame. Once located, use a wrench to loosen and remove the positive and negative battery terminals. Check that the motor does not turn on and that the electric clutch is no longer receiving power.
After disconnecting the spark plug, you can proceed with removing the electric clutch. This process involves removing any protective covers, loosening and detaching the clutch from its mounting points, and finally, disconnecting the wiring.
It is important to note that lawn mower engines can be hazardous to work on. Always use the proper tools and safety equipment, and follow all instructions. Do not proceed with any repairs unless you are confident that you understand all the steps and are capable of completing them safely. Some repairs may require the assistance of a qualified technician.
Additionally, always be cautious of moving parts and avoid contact with them. Wear safety glasses and gloves to protect your eyes and hands from any debris or sharp edges.

Use an impact gun
To remove an electric clutch from a lawn mower using an impact gun, you will need to follow a few crucial steps. Firstly, it is important to prioritise safety. Disconnect the spark plug to prevent accidental ignition, and always wear safety glasses when working with tools and machinery. Ensure your lawn mower is on a stable and level surface, and be cautious of any moving parts, avoiding contact with them.
Next, you will need to disconnect the power supply to the electric clutch. This is a critical step to prevent accidental activation during the removal process. Locate the battery, which is typically near the engine or in a compartment on the mower's frame. Disconnect the battery terminals using a wrench to loosen and remove the positive and negative terminals.
Now, we can focus on the impact gun. With your safety measures in place and the power supply disconnected, you are ready to use the impact gun to remove the clutch bolt. The impact gun will deliver a rapid burst of force to loosen the bolt. If your electric clutch is rusted or seized, the impact gun's force may be necessary to break it free.
Once the bolt is removed with the impact gun, you can proceed with the rest of the removal process. Loosen and detach the clutch assembly from its mounting points, and finally, disconnect the wiring. Remember to label the wires and their corresponding terminals to make reassembly easier.
Using an impact gun can be an effective way to remove the clutch bolt quickly and efficiently. However, always exercise caution when using power tools, and ensure you have the necessary safety equipment and knowledge to operate them safely.

Remove the mower deck belt
To remove the mower deck belt, follow these steps:
First, disengage the mower deck and wait for it to come to a complete stop. Then, engage the mower deck again and listen for any abnormal sounds. Disengage the mower deck once more, bring the throttle down to idle, and turn off the riding lawn mower. Remove the ignition key and the spark plug wire(s). Remember to ground the spark plug wire(s) against the engine to prevent unintended starting.
Next, adjust the deck to its lowest position. Check the mower deck belt to ensure it is running properly through all the pulleys and that there is no damage. Once you have confirmed these, you can proceed to remove the belt.
Loosen, but do not remove, the idler pulley nuts. This will allow you to easily remove the mower deck belt from around the idler pulleys. Remember to not put your fingers on the idler spring or between the mower deck belt and any pulleys to avoid injury. Remove the belt from around all the pulleys, including the deck idler pulleys.
Finally, route the new mower deck belt in the same manner as the old one, using a reference photo or your operator's manual. Tighten the idler pulley nuts and put the belt keeper rod back in place around the engine pulley.

Unplug the electrical connector
To unplug the electrical connector from the electric clutch of a lawn mower, you must first lift the front of the machine and place it on jack stands. This will make it easier to access the mower deck belt and the electrical connector.
Next, remove the mower deck belt from the PTO clutch. Be sure to pay attention to how the belt is positioned so that you can put it back correctly later.
Now you can unplug the electrical connector. Be sure to secure it out of the way so that it doesn't get pulled loose or damaged while you work on the rest of the removal process.
After unplugging the electrical connector, you can move on to removing the bottom bolt from the PTO clutch. If your clutch is rusted in place, you may need to use an impact wrench or try some of the other methods suggested for removing stubborn clutches.

Remove the clutch, paying attention to its position
Before removing the clutch, it is important to disconnect the spark plug to prevent accidental ignition. It is also important to wear safety glasses and gloves when removing the clutch. Now, let's get into the steps for removing the clutch, paying close attention to its position:
First, locate the battery and disconnect the battery terminals using a wrench. Confirm that the power is off by briefly testing the motor to ensure it does not turn on. Next, remove any protective shrouds or covers over the clutch assembly by unscrewing the screws or bolts using a screwdriver or socket wrench. Set the cover aside carefully.
Now, we can begin to remove the clutch itself. Pay close attention to the clutch's position and how it is oriented against the locator pin or tab that mates against it to keep it from spinning. Make sure the upper engine pulley stays in place as you remove the clutch. Once the clutch is removed, use a compound like NeverSeez on the crankshaft to prevent rusting and make future removals easier.
Finally, if you plan to reinstall the clutch, make sure to orient it properly against the pin or tab, then replace the washer and bolt. If you are installing a new clutch, ensure it is positioned correctly. Line up the slot in the electric clutch pulley with the key in the engine shaft and push the clutch onto the shaft. Reattach the flywheel cover and reconnect the wire harness, ensuring it is routed correctly.
