John Deere Lawn Mower Troubleshooting. When your lawn is getting higher and not mowed, it’s frustrating to deal with. Fortunately, there are basic things you can do to get the job done that include: Check the oil levels; checking the fuel level to make sure it has plenty of gas in it. Make sure the fuel tap is on.

Make sure the air filter is clean and make sure that its cover is back on correctly. Do a quick check to see if the plug wire can be wiggled and make sure it’s attached to its base.

Finally, apply the choke properly and start-up following this basic starting procedure.

Our goal here is to troubleshoot a few problems with a John Deere lawnmower.

Lawn Mower Will Not Start

The carburetor may be clogged. A common cause of a clogged carburetor is an old fuel mixture that has become thicker over time. To try to clear out the clog, use a can of carburetor cleaner. If cleaning does not work, you may need to replace the entire carburetor or rebuild it entirely from scratch.

The fuel filter might be clogged. There are usually two fuel filters at work in the lawnmower – one inside the fuel tank and one inside the carburetor.

If these are not regularly cleaned, they can become clogged with sediment from new fuel and can create trouble when used. To stop this from recurring, make sure you regularly clean or replace your fuel filter to ensure the smooth running of your machine.

Lawn Mower Leaks Gas

The float needle may not be shutting off the fuel. The float needle is one part of a float needle assembly that needs replacing if it becomes worn or damaged.

If your carburetor continues to fill with fuel, drain it until you can get a replacement float needle.

If your float is stuck open, it may be because dust or dirt has accumulated in your carburetor assembly. If there’s a build-up of dust or dirt inside the carburetor assembly, then you should clear it to ensure that the float is able to work properly again.

Make sure you check all areas including where the float attaches to the rest of the carburetor, as this can allow dirt or other debris to get stuck in-between parts and set off a chain reaction of problems.

Lawn Mower Running Rough

To inspect the spark plug, check if it’s worn out or damaged. If the design on the porcelain insulator is cracked or scorched, replace it with a new one.

You can determine if the spark plug should be replaced by using a spark plug tester. A strong spark should appear between its terminals when the engine is cranking.

The defect of a defective spark plug can reveal itself in one of two ways t either can’t start sparking at all or does so poorly. So make sure to test the engine start with your spark plug tester and look for a strong current. This shows that your malfunctioning heat source needs replace.

If the carburetor assembly may be clogged. The most common cause of a clogged carburetor is leaving fuel in your lawnmower for an extended period.

Over time, the mower will use fuel and some of the ingredients can evaporate leaving behind a thicker substance that can clog up the bowl and prevent the fuel from mixing properly with air leading to rough idling, or worse it can even lead to a fire.

There’s no polite way to say this so we will just be honest: You’re going to have to start all over Billy.

The Lawn Mowing Battery Keeps Dying

The alternator is used on petrol mowers as a motor that converts mechanical energy from the engine into electrical energy and also recharges the battery.

The multimeter can be tested to see if it’s defective by using it for checking the output voltage on an alternator wiring diagram.

To determine if a charger and cable are broken you need to plug in a multimeter when charging your phone. The multimeter will tell you the exact voltage of the charger.

If there is an issue with the charger, do not use it. Check all outlets for any possible issues and be sure that the area is free from any fire hazards.

Lawn Mowers Are Not Self-Propelled

The drive pulley is connected to the engine’s crankshaft (which is what rotates when the car is on). If the drive pulley has become worn out or damaged, it can cause there to be a problem in the transmission connecting to the wheel assembly.

Inspect the driveshaft pulley – if it is faulty, replace it with a new one.

The wheel assembly features gears that engage with the drive gear of the transmission. If these gears are worn out, you may need to replace the wheel assembly because if they are unable to engage then the transmission will be unable to operate them.
