The sweet smell of freshly cut grass and the satisfying hum of a well-maintained lawnmower are the hallmarks of a well-kept yard. But what happens when that hum turns into a sputter, your lawnmower starts wheezing, or worse, refuses to start at all? You might be looking at a frustrating afternoon of yard work.
This article will guide you through the common problems encountered with Yard Machine lawnmowers and equip you with the knowledge to diagnose and fix them yourself. From engine issues to blade problems, we’ll cover everything you need to know to get your Yard Machine lawnmower back in tip-top shape.
A Quick Overview of Yard Machine Lawn Mower Issues
Yard Machine lawnmowers, like all mechanical devices, are prone to wear and tear. Common problems include engine starting difficulties, engine performance issues, and cutting problems. The good news is, with a little bit of know-how and the right tools, many of these issues can be tackled by homeowners without needing to call a professional.
Diagnosing the Problem
The first step to fixing your Yard Machine lawnmower is pinpointing the problem. Start by asking yourself the following questions:
- Does the lawnmower start at all?
- If it starts, does it run smoothly?
- Is the engine running but the blades are not spinning?
- Are you experiencing any cutting issues, such as uneven cuts or scalping?
By answering these questions, you can narrow down the potential issues and direct your troubleshooting efforts accordingly.
Common Yard Machine Lawn Mower Problems and Solutions
Engine Starting Issues
Problem: The Engine Won’t Start
This is perhaps the most common lawnmower problem. There are a few reasons why your Yard Machine lawnmower might not start:
- Dead Battery: If your lawnmower is battery-powered, the battery may be dead.
- Old Fuel: Old gasoline can gum up the carburetor, preventing the engine from starting.
- Clogged Air Filter: A dirty air filter restricts airflow to the engine, hindering combustion.
- Spark Plug Issues: A faulty spark plug or a fouled spark plug can prevent a spark, stopping the engine from firing.
Solution:
- Check the Battery: If your lawnmower is battery-powered, ensure the battery is charged or replace it if it’s too old.
- Replace Old Fuel: Drain the old fuel from the tank and replace it with fresh, high-octane gasoline.
- Clean the Air Filter: Remove the air filter and clean it with a brush or compressed air. If it’s beyond cleaning, replace it.
- Inspect the Spark Plug: Remove the spark plug and inspect it. If it’s fouled with carbon, clean it or replace it. Test it by holding it near the spark plug wire and grounding the plug to the engine block. If it sparks, the problem lies elsewhere.
Engine Performance Issues
Problem: The Engine Runs but Sputters or Dies
If your Yard Machine lawnmower starts but doesn’t run smoothly, you may have a fuel or ignition problem.
- Fuel Problems: A clogged fuel line or carburetor, or a bad fuel filter, can restrict fuel flow to the engine.
- Spark Plug Issues: A worn-out or fouled spark plug can cause the engine to misfire.
Solution:
- Inspect the Fuel Line and Fuel Filter: Check for any blockages or kinks in the fuel line. Replace the fuel filter if it’s dirty or damaged.
- Clean the Carburetor: A dirty carburetor can be a common culprit. Cleaning it involves removing it and disassembling it. Use a carburetor cleaner and a small brush to clean the jets and other components.
- Replace the Spark Plug: If the spark plug is worn or fouled, replace it with a new one.
Cutting Problems
Problem: Uneven Cuts or Scalping
If your Yard Machine lawnmower is leaving an uneven cut or scalping your lawn, the problem might be with the blades or the cutting height adjustment.
- Bent or Dull Blades: Bent or dull blades can cause uneven cuts and scalping.
- Improper Cutting Height: Setting the cutting height too low can also lead to scalping.
Solution:
- Sharpen or Replace Blades: Sharpen the blades with a file or replace them with new ones. When sharpening, ensure you maintain the original blade angle.
- Adjust the Cutting Height: Adjust the cutting height to a suitable level. It’s best to start with a higher setting and gradually lower it if needed.
Blade Issues
Problem: Blades Are Not Spinning
If the engine is running but the blades aren’t spinning, the problem might be with the blade clutch, the blade shaft, or the belt.
- Faulty Blade Clutch: The blade clutch engages and disengages the blades. A worn-out or faulty clutch can prevent the blades from spinning.
- Broken Blade Shaft: A broken blade shaft will prevent the blades from rotating.
- Broken or Loose Belt: The belt connects the engine to the blade shaft. A broken or loose belt will prevent power transfer to the blades.
Solution:
- Inspect the Blade Clutch: Check for any damage or wear on the clutch. If it’s worn out, it needs to be replaced.
- Examine the Blade Shaft: Inspect the blade shaft for any cracks or breaks. If it’s damaged, it will need to be replaced.
- Inspect the Belt: Ensure the belt is intact and properly tensioned. If it’s broken or loose, replace it with a new one.
