Troubleshooting your Toro SR4 Super Recycler lawn mower involves a systematic approach to identify and resolve issues. Here are some common problems and their potential solutions:

### 1. **Mower Won’t Start**
– **Check Fuel:** Ensure that the mower has fresh gasoline. Stale fuel can cause starting problems.
– **Inspect the Spark Plug:** Remove the spark plug and check for wear or carbon buildup. Clean or replace it if necessary.
– **Battery (if applicable):** If your model has an electric start, check the battery charge and connections.

### 2. **Engine Starts, But Does Not Run Smoothly**

– **Air Filter:** A dirty air filter can restrict airflow. Clean or replace the air filter.
– **Carburetor Issues:** If the carburetor is dirty or not functioning correctly, it may need cleaning or adjustment.

### 3. **Mower is Cutting Unevenly**
– **Blade Condition:** Inspect the blade for dullness or damage. Sharpen or replace the blade if needed.
– **Deck Leveling:** Check if the mower deck is level. Adjust the deck height accordingly to ensure even cutting.

### 7. **Mower Won’t Self-Propel**
– **Drive System:** Check the drive belt for wear or breakage. Replace if necessary.
