Identifying the Problem: A Starting Point
Before diving into repairs, it’s essential to pinpoint the specific problem you’re facing. This will help you narrow down the potential causes and avoid unnecessary troubleshooting. Here are some common symptoms and their possible causes:
1. The Mower Won’t Start:
- Dead Battery: A dead battery is a common culprit for a no-start situation. Check the battery terminals for corrosion and ensure the battery is charged.
- Fuel Issues: A clogged fuel filter, bad fuel, or a faulty fuel pump can prevent fuel from reaching the engine.
- Spark Plug Problems: A fouled or worn-out spark plug can hinder ignition.
- Engine Problems: A stuck valve, damaged starter motor, or a faulty ignition system could be the root cause.
2. The Mower Runs Rough or Stops Suddenly:
- Fuel System Problems: A dirty carburetor or fuel line, water in the fuel, or a clogged fuel filter can cause erratic engine behavior.
- Spark Plug Problems: A fouled or worn spark plug can lead to misfires and stalling.
- Air Filter Problems: A clogged air filter restricts airflow to the engine, causing performance issues.
- Engine Problems: Worn-out engine components, like the piston rings or valves, can lead to roughness and stalling.
3. The Mower Cuts Unevenly or Doesn’t Cut Well:
- Blade Problems: Dull, bent, or unbalanced blades result in uneven cuts.
- Deck Problems: A clogged deck, worn-out bearings, or a misaligned deck can affect the cutting height and quality.
- Engine Problems: A lack of power from the engine can lead to uneven cutting.
4. The Mower Overheats:
- Cooling System Problems: A clogged radiator, faulty cooling fan, or low coolant level can cause the engine to overheat.
- Engine Problems: Worn-out engine parts can lead to increased friction and overheating.
Engine Troubleshooting: Getting Your Craftsman Running Again
The engine is the heart of your Craftsman riding mower, and troubleshooting its problems is crucial. Here’s a breakdown of common engine issues and how to fix them:
Starting Problems
1. Battery Check:

- Replace the battery if it’s beyond repair.
2. Fuel System Check:
- Examine the fuel filter for clogs. Replace it if necessary.
- Inspect the fuel lines for kinks or cracks. Replace any damaged lines.
- Check the fuel tank for water or debris. Drain and refill the tank with fresh fuel.
- Clean or rebuild the carburetor if necessary. This is a more complex task, and it’s advisable to consult a repair manual or seek professional assistance.
3. Spark Plug Check:
- Remove the spark plug and inspect it for wear, fouling, or damage.
- Clean or replace the spark plug if needed. A new spark plug should have a clean gap of 0.030 inches.
4. Ignition System Check:
- Inspect the ignition coil and wires for damage. Replace any faulty components.
- Test the ignition coil and wires with a multimeter. Consult a repair manual for testing procedures.
Fuel System Issues
1. Fuel Line Problems:
- Inspect the fuel lines for kinks, cracks, or leaks. Replace damaged lines.
- Ensure the fuel lines are properly connected.
- Check the fuel line for clogs. Blow compressed air through the line to clear any obstructions.
2. Fuel Filter Problems:
- Inspect the fuel filter for clogs. Replace it with a new filter.

3. Carburetor Problems:
- Clean the carburetor if it’s dirty. This can be done with a carburetor cleaning kit.
- Adjust the carburetor if necessary. Consult your mower’s manual for specific adjustments.
- Replace the carburetor if it’s beyond repair.
Engine Overheating
1. Cooling System Check:
- Check the coolant level in the radiator. Add coolant if needed.
- Inspect the radiator for clogs. Flush the radiator with a solution of water and vinegar.
- Check the cooling fan for proper operation. Ensure the fan spins freely and engages when the engine heats up.
2. Engine Problems:
- Inspect the engine for leaks or damage.
- Check the engine oil level. Add oil if needed.
- Replace any worn-out engine components. Consult a repair manual for specific parts and procedures.
Deck Maintenance: Keeping Your Cut Clean
The deck is the part of the mower that houses the blades and creates the cut. Maintaining your deck is essential for a clean and even cut:
Blade Maintenance
1. Inspect the Blades:
- Check the blades for dullness, bends, or cracks.
- Sharpen or replace dull blades.
- Balance the blades to prevent vibrations and uneven cuts.
2. Blade Installation:
- Follow the manufacturer’s instructions for blade installation.
- Ensure the blades are securely mounted on the deck.
Deck Maintenance
1. Deck Cleaning:
- Clean the underside of the deck to remove grass clippings and debris.
- Use a deck cleaning solution for a thorough cleaning.
2. Deck Height Adjustment:
- Adjust the deck height to achieve the desired cut height.
- Ensure all wheels are adjusted to the same height for an even cut.
3. Bearings and Belts:
- Inspect and lubricate the deck bearings.
- Check the belts for wear or damage. Replace worn or damaged belts.
