Gather Your Tools and Materials
Before you begin, ensure you have the following tools and materials readily available:
- New spark plugs: Refer to your John Deere D130 owner’s manual for the correct spark plug type and gap specifications.
- Spark plug socket: This specialized socket has a rubber insert to grip the spark plug securely.

Safety First: Prepare Your Work Area
Safety should always be your top priority. Follow these steps to prepare a safe environment for working on your John Deere D130:
1. Park the tractor on a level surface: Ensure the tractor is securely parked on a flat, stable area.
2. Disengage the parking brake: This will prevent the tractor from moving during the repair.
3. Disconnect the battery: Locate the battery and disconnect the negative (-) terminal first, followed by the positive (+) terminal. This will prevent electrical shocks.
4. Allow the engine to cool completely: This is crucial to avoid burns and prevent accidental ignition of fuel vapors.
Locate the Spark Plugs
The spark plugs on your John Deere D130 are typically located on the top of the engine, under the engine cover.
1. Remove the engine cover: Locate the engine cover and remove any clips or screws holding it in place.
2. Identify the spark plugs: The spark plugs will be visible on the engine’s cylinder head. They are usually cylindrical with a wire connected to the top.
Remove the Old Spark Plugs
1. Disconnect the spark plug wires: Use your wrench to loosen the nut holding the spark plug wire to the spark plug. Disconnect the wire carefully, ensuring you don’t damage the wire or the spark plug.
2. Remove the spark plug: Place the spark plug socket over the spark plug and use a wrench to turn the socket counterclockwise to loosen the spark plug.
3. Inspect the old spark plug: Examine the old spark plug for signs of wear, damage, or carbon buildup. This will help you assess the condition of your engine.
Install the New Spark Plugs
1. Clean the spark plug threads: Use a shop towel to clean the spark plug threads on the engine cylinder head. This removes any debris that could interfere with proper installation.
2. Install the new spark plug: Carefully thread the new spark plug into the cylinder head by hand. Ensure the threads are aligned correctly and the spark plug is going in straight.
3. Tighten the spark plug with a torque wrench: Use your torque wrench to tighten the spark plug to the manufacturer’s specified torque setting. Overtightening can damage the spark plug, while undertightening can cause leaks.
4. Reconnect the spark plug wire: Reconnect the spark plug wire to the new spark plug, ensuring it is securely fastened.
5. Repeat for all spark plugs: Follow the same steps for each spark plug on your John Deere D130 engine.
Reassemble and Test
