## Step-by-Step Guide to Starting Your John Deere Riding Mower
Follow these steps to start your John Deere riding mower:
**1. Pre-Start Checks:**
* **Check the Fuel Level:** Ensure there’s sufficient fuel in the tank. Use fresh, clean gasoline with the recommended octane rating. Avoid using old fuel, as it can degrade and cause starting problems. A fuel stabilizer can help prevent fuel degradation, especially if the mower is stored for extended periods.
* **Inspect the Engine Oil Level:** Use the dipstick to check the oil level. Add oil if necessary, using the type and grade recommended in your operator’s manual. Low oil levels can damage the engine.
* **Examine the Air Filter:** A dirty air filter restricts airflow and can make the engine difficult to start. Clean or replace the air filter if it’s dirty.
* **Check the Battery:** Ensure the battery is properly connected and charged. Clean any corrosion from the battery terminals. If the battery is weak, it may need to be charged or replaced.
* **Inspect the Spark Plug:** Check the spark plug for damage or fouling. Clean or replace the spark plug if necessary. A faulty spark plug can prevent the engine from starting.
* **Check the Blade Engagement (PTO):** Make sure the blades are disengaged. The PTO lever or switch should be in the “OFF” position.
**2. Setting the Controls:**
* **Engage the Parking Brake:** This prevents the mower from moving during starting.
* **Neutral Position:** Ensure the transmission is in neutral. This prevents the mower from lurching forward or backward when started.
* **Throttle Position:** Set the throttle lever to the idle or slow position (usually marked with a turtle symbol).
* **Choke (if necessary):** If the engine is cold, pull the choke control out to enrich the fuel mixture. The amount of choke needed will vary depending on the ambient temperature and the engine’s condition. For warm starts, you may not need to use the choke at all. Refer to your operator’s manual for specific choke instructions for your model.
**3. Starting the Engine:**
* **Insert the Key:** Insert the key into the ignition switch.
* **Turn the Key:** Turn the key to the start position and hold it there until the engine starts. Avoid cranking the engine for more than 10-15 seconds at a time. If the engine doesn’t start, release the key, wait a few seconds, and try again.
* **Adjust the Choke:** Once the engine starts, gradually push the choke control in as the engine warms up. If you leave the choke on for too long, the engine may run roughly or stall.
* **Throttle Adjustment:** After the engine has warmed up for a minute or two, gradually increase the throttle to the desired operating speed.
**4. After Starting:**
* **Listen to the Engine:** Pay attention to the engine’s sound. A smooth, consistent sound indicates proper operation. Unusual noises may indicate a problem.
* **Check for Smoke:** A small amount of white smoke is normal during a cold start, but excessive smoke of any color may indicate a problem.
* **Engage the Blades:** Once you’re ready to mow, engage the blade engagement lever or switch (PTO). Ensure the area is clear of obstacles before engaging the blades.
## Troubleshooting Common Starting Problems
If your John Deere riding mower doesn’t start, consider these common issues and solutions:
* **No Cranking:**
* **Dead Battery:** The most common cause of no cranking is a dead battery. Check the battery voltage with a multimeter. If the voltage is low, charge the battery or replace it if necessary. Clean the battery terminals to ensure a good connection.
* **Loose Battery Connections:** Ensure the battery cables are securely connected to the battery terminals. Clean any corrosion from the terminals.
* **Faulty Starter Solenoid:** The starter solenoid relays power from the battery to the starter motor. If the solenoid is faulty, it may not allow the starter motor to engage. You can test the solenoid with a multimeter or by bypassing it temporarily (use caution when bypassing the solenoid).
* **Seat Safety Switch:** The seat safety switch prevents the mower from starting unless the operator is seated. Ensure the switch is functioning correctly. You can test the switch with a multimeter or temporarily bypass it (use caution).
* **Parking Brake Switch:** A faulty parking brake switch can also prevent the mower from starting. Ensure the switch is functioning correctly.
