Engine overheatingDamaged components in the coolant system Replace the damaged component. 
Rough running engineDamaged ignition switch Replace the ignition. 

Problem 1: Engine Will Not Start

The engine not starting can be because of problems with the fuel filter.


Replacing the fuel filter located inside the fuel pump will solve the issue. 

Tools Needed: 

  • Pliers
  • User’s Manual
Step 1: Disconnect the Battery

Place the lawnmower on a flat area and then switch off the engine. Then, disconnect the batteries. This is to protect yourself from an electrical shock and to maintain your safety.

Step 2: Locate the Fuel Pump

Inside the fuel tank is normally where one will find the fuel pump on a John Deere LX277. It will be necessary to remove the fuel tank from the mower. That is in order to have access to the fuel pump.

Mostly, removing the fuel tank only requires the removal of a few clamps that are holding it in place. Use the plier to loosen the clamps. And then remove it from the mower altogether.

After the tank has been taken out of the way, you will have access to the fuel pump. The fuel pump can either be found at the very bottom of the tank. Or anywhere within the tank itself. 

The precise location of the fuel pump in your John Deere LX277 might change depending on whatever model you have. 

So it is strongly suggested that you consult the john deere LX277 manual that comes with the model that you own. Because it will have comprehensive instructions on how to find the fuel pump and gain access to it.

Step 3: Remove the Fuel Filter 

Use the pliers once more. This time remove the clamps that are securing the fuel filter in place.

It is important to remove the fuel filter from the fuel line with extreme caution. Be very careful not to let any fuel leak out.

Step 4: Install the New Fuel Filter 

Simply replace the old fuel filter with the new fuel filter in the same location as the old fuel filter. Check that the arrow on the fuel filter is pointing in the direction that fuel is being pumped through the system.

Put the clamps back on the filter so that the filter can be held in place securely. After reattaching the battery and starting the engine, check for any leaks that may have developed.

You can go for a test drive in the mower if everything seems to be operating normally.

Problem 2: Rough Running Engine

A malfunctioning ignition module or a problem with the ignition timing can cause a rough-running engine.


Replacing the defective ignition switch will solve the issue. 

Tools Needed: 

  • Flat blade screwdriver
Step 1: Disconnect the Battery

Turn off the engine and park the mower in a flat place. After that, disconnect the battery. This is to protect yourself from getting shocked by electricity and to secure your safety.

Step 2: Remove the Ignition Switch 

Find the switch that turns the engine on and off on the dashboard. It is typically located close to the wheel that steers the vehicle.

At this point, you should take the key out of the ignition switch. To accomplish this, take the little screwdriver with the flat blade and remove any screws or clips. Remove all the screws that are securing the switch in place.

After that, detach the ignition switch from the dashboard in a cautious manner. Take special care to not lose any of the smaller components or cables that might be attached to it.

Pull the wires away from the back of the ignition switch so that they can be disconnected. You can do this by removing the clips or by unscrewing the nuts. Now simply remove the ignition switch. 

Step 3: Install the New Ignition Switch 

Now, get the replacement ignition switch, and attach the wires to it. Do this in the exact same way that you did with the previous switch. 

Replace the ignition switch in the dashboard in a careful manner. After that, reinstall any screws or clips that were taken out earlier in the process.

After reconnecting the battery, put the switch through its paces. Do this to check that it is operating as it should. You can now start up your mower and give it a spin to see if everything is functional.

Problem 3: Overheating Engine 

The cooling system is responsible for managing the heat of the whole machine. Any problems with the cooling system can lead to the engine overheating 


Locating the fault in the cooling system and fixing it.

Tools Needed: 

  • User’s Manual
Step 1: Check the Coolant Fluid Level

Check the radiator to see if it has the appropriate amount of coolant in it. If the level of the coolant is low, it is likely that there is a leak in the surrounding area.

There is also the possibility that there is a problem with the circulation of the coolant throughout the system.

The instruction manual will provide you with the information you need to locate the radiator. The user’s manual will be helpful for all of the steps that are still to come as well, so make sure to have it handy.

Step 2: Check the Radiator for Issues

Perform a complete inspection of the hoses, as well as the radiator. Examine both of these components carefully, looking for any obvious evidence of damage or leakage. 

In the event that you discover a leak, getting it fixed as quickly as you can is an absolute must.

Step 3: Check the Thermostat for Issues

Make sure the thermostat is in operating condition by giving it a careful inspection. Make any necessary adjustments. 

The thermostat is responsible for controlling and regulating the amount of coolant that is circulated throughout the system. Overheating is more likely to occur in mowers that have thermostats that are not functioning properly.

Step 4: Replace the Defective Components

At this stage, you should have identified the component of the cooling system that is faulty. Either fix the broken component or replace it in order to solve the problem with the cooling system.

The structure of the cooling system is very intricate overall. It is strongly discouraged that you work on it if your abilities are not previously experienced.

If you do discover an issue, though, it is strongly suggested that you consult a trained professional. Alternatively, you could go to a John Deere dealership.

The wiring that is damaged or hanging loose should be replaced. And you should check that all connections are secure.

Step 3: Calibrate the Sensor

If the sensor is clean and the wiring is correct, then the problem might lie with the calibration. 

To calibrate the AWS sensor, first park the mower on a level surface and turn off the engine. Then locate the AWS sensor on the top of the mower deck.

Now use the flat-blade screwdriver. Turn the adjustment screw on the sensor counter-clockwise until it stops. Turn the screw clockwise until it stops again. Then turn the screw one-quarter turn clockwise. This is the calibrated position.

Battery not charging Faulty battery Replace the battery via a professional. 
Faulty alternator diodeReplace the alternator diode.

Problem: Battery Not Charging 

The battery may not charge because of a fault in the battery itself. In that case, the battery would need to be replaced. But more often the problem is caused by faulty alternators. 


Fixing the alternator will solve the john deere lx277 charging problems.

It is strongly suggested that you consult the user manual that comes packaged with the model that you now own. Because it will include comprehensive directions that explain where the alternator may be found.

Step 2: Remove the Alternator 

Take out the alternator that’s attached to the mowers. To do so, you’ll have to uninstall all mounting bolts or brackets securing the alternator in place

Also, remove any electrical connections that are currently attached to the alternator. And then disconnect them.

Step 3: Replace the Malfunctioning Diode 

Examine the alternator for any obvious symptoms that might indicate a defective diode. The diode is located within the alternator itself. It is responsible for regulating the flow of energy through the alternator. 

It is necessary to take the diode out of the alternator. That’s the case if there’s a problem with it breaking or otherwise not working properly.

To remove the diode, you will need to make use of a soldering iron or another device of a similar nature. This is in order to carefully remove the diode from the alternator.

After you have removed the defective diode, you will need to replace it with a new diode. In order to accomplish this, you will again need to make use of a soldering iron or a similar device. Use it to delicately attach the new diode to the alternator.

Step 4: Reinstall the Alternator 

After you have done installing the new diode, you will need to put the alternator back together again. After that, you should reconnect it to the mower.
