Getting Your Murray Riding Mower Started: A Step-by-Step Guide
Starting a Murray riding lawn mower is a straightforward process once you understand the essential steps and safety precautions. We’ll break it down into manageable sections to ensure you can tackle it with confidence. Before you even think about turning the key, it’s crucial to prioritize safety. Riding mowers are powerful machines, and a little preparation goes a long way.
1. Safety First: Essential Pre-Start Checks
Safety is paramount when operating any lawn mower, especially a riding one. Always ensure you’re in a well-ventilated area, away from children and pets. Never attempt to start the mower indoors or in an enclosed space due to the risk of carbon monoxide poisoning.
- Clear the Area: Before starting, walk around the mower and the area where you’ll be mowing. Remove any rocks, toys, branches, or debris that could be picked up by the blades.
- Engage the Parking Brake: Always ensure the parking brake is firmly engaged. This prevents the mower from moving unexpectedly when you attempt to start it.
- Operator Presence Control: Most modern riding mowers have an operator presence control system. This means the engine will shut off if you leave the seat while the blades are engaged. Ensure you are seated firmly before attempting to start.
- Blades Disengaged: Make sure the mower deck’s blade engagement lever is in the ‘disengaged’ or ‘off’ position. Starting the engine with the blades already engaged can be dangerous and strain the engine.
- Check for Leaks: Visually inspect the mower for any signs of fuel or oil leaks. If you find any, do not attempt to start the mower. Address the leak first.
2. Fueling Your Murray Mower
A common reason a mower won’t start is simply a lack of fuel. It sounds obvious, but it’s easily overlooked! (See Also: How to Start Black and Decker Electric Lawn Mower)
- Check the Fuel Level: Locate the fuel tank, usually found under the seat or on the fender. Check the fuel gauge or visually inspect the tank. If it’s low, you’ll need to add fuel.
- Use the Correct Fuel: Always use fresh, unleaded gasoline. Avoid using old fuel that has been sitting for months, as it can degrade and cause starting problems. For most Murray mowers, 87 octane is sufficient. Refer to your owner’s manual for specific recommendations.
- Adding Fuel Safely: Ensure the engine is off and cool. Slowly pour fuel into the tank, being careful not to overfill. Wipe up any spills immediately.
3. Understanding the Ignition System
The ignition system is what provides the spark to ignite the fuel-air mixture in the engine. This involves the key switch, ignition coil, spark plug, and related wiring.
The Key Switch
The key switch is your primary interface for starting the mower. It typically has several positions:
- OFF/STOP: This is the starting position. Ensure the key is in this position before you begin.
- ON/RUN: In this position, the engine is running.
- START: When you turn the key to this position, the starter motor engages.
The Choke
The choke is essential for starting a cold engine. It restricts airflow into the carburetor, creating a richer fuel-air mixture that is easier to ignite when the engine is cold.
- Cold Engine: For a cold start, you’ll typically need to engage the choke. This might be a lever on the dashboard or a pull/push knob. Move it to the ‘choke’ or ‘full choke’ position.
- Warm Engine: If the engine is already warm, you may not need to use the choke, or you might only need to partially engage it. Using the choke on a warm engine can cause it to flood and refuse to start.
4. The Starting Procedure: Step-by-Step
Now that you’ve covered the safety checks and ensured you have fuel, it’s time to start your Murray riding mower. Follow these steps carefully: (See Also: How to Attach Grass Catcher to Craftsman Lawn Mower)
- Ensure Safety: Double-check that the parking brake is engaged, you are seated firmly, and the blade engagement lever is disengaged.
- Insert the Key: Insert the ignition key into the key switch.
- Set the Choke (if needed): If the engine is cold, move the choke lever or knob to the ‘full choke’ position. If the engine is warm, you may not need to use the choke at all, or just a partial choke.
- Turn the Key to START: Turn the key to the ‘START’ position. Hold it there until the engine begins to crank and then runs. Do not crank the engine for more than 5-10 seconds at a time. If it doesn’t start, release the key and wait about 30 seconds before trying again. This prevents overheating the starter motor.
- Adjust the Choke as the Engine Warms: As the engine starts and runs, gradually move the choke lever or knob towards the ‘run’ or ‘off’ position. You want to maintain a smooth idle without the engine stalling. For a cold engine, this might take a minute or two.
- Disengage the Choke: Once the engine is running smoothly and consistently, ensure the choke is fully in the ‘run’ or ‘off’ position.
5. Troubleshooting Common Starting Problems
Even with the correct procedure, your Murray riding mower might still refuse to start. Here are some common issues and how to address them:
The Engine Cranks but Won’t Start
This usually indicates a problem with the fuel or ignition system.
- Fuel Issues:
- No Fuel: Double-check the fuel level.
- Stale Fuel: If the fuel is old, it might need to be drained and replaced with fresh fuel.
- Clogged Fuel Filter: The fuel filter can become clogged over time. Locate it (usually in the fuel line between the tank and the carburetor) and check if it’s dirty. Replacing it is a relatively simple task.
- Carburetor Problems: The carburetor might be clogged or dirty. This often requires cleaning or rebuilding the carburetor, which can be more complex.
- Ignition Issues:
- Spark Plug: The spark plug might be fouled, dirty, or damaged. Remove it, check its condition, clean it if necessary, or replace it. Ensure the gap is set correctly according to your mower’s manual.
- Ignition Coil: A faulty ignition coil will prevent spark. This is a more advanced repair.
- Ignition Switch/Wiring: Damaged wiring or a faulty ignition switch can interrupt the electrical flow to the ignition system.
The Engine Doesn’t Crank at All
If you turn the key and nothing happens, the problem is likely with the electrical system or the starter.
- Battery: The most common culprit is a dead or weak battery.
- Check Connections: Ensure the battery terminals are clean and the cables are securely attached. Corroded terminals can prevent power flow.
- Test the Battery: Use a multimeter to check the battery’s voltage. If it’s below 12 volts, it needs to be charged or replaced.
- Charge the Battery: Use a suitable battery charger designed for lawn mower batteries.
- Fuse: Many riding mowers have a fuse in the electrical system. Check your owner’s manual for its location and inspect it for being blown.
- Starter Solenoid: The starter solenoid is an electrical switch that engages the starter motor. If it’s faulty, the starter won’t engage.
- Starter Motor: The starter motor itself might be worn out or have internal issues.
- Seat Safety Switch: Ensure the seat safety switch is functioning correctly. If the mower thinks you’re not seated, it won’t allow the starter to engage.
- Neutral Safety Switch (if applicable): Some mowers have a neutral safety switch that prevents starting if the transmission is not in neutral.
The Engine Starts but Immediately Stalls
This often points to a lean fuel mixture or an issue with the governor or air intake. (See Also: Want a Faster Lawn? Here’s How to Increase Speed on Lawn)
- Choke Adjustment: If you’re not gradually reducing the choke as the engine warms, it can stall.
- Air Filter: A severely clogged air filter can restrict airflow, causing the engine to stall. Check and clean or replace it.
- Fuel Delivery: A partially clogged fuel line or filter can cause intermittent fuel starvation.
- Idle Speed: The idle speed might be set too low.
6. Maintenance Tips for Easy Starts
Regular maintenance is the best way to prevent starting problems. Here are some key areas to focus on:
- Regular Oil Changes: Ensure your engine oil is at the correct level and changed at recommended intervals.
- Clean or Replace Air Filter: A clean air filter is crucial for proper engine combustion.
- Check and Replace Spark Plug: A fouled or worn spark plug is a common cause of starting issues. Replace it annually or as needed.
- Keep Fuel System Clean: Use fuel stabilizer, especially if storing the mower for extended periods, to prevent fuel degradation.
