Greenworks Lawn Mower Won't Start: Causes and Solutions

Greenworks is a well-known brand that produces high-quality lawn mowers. However, even the best machines can sometimes experience issues. One of the most common problems that users encounter with Greenworks lawn mowers is when they won't start.

In this article, we'll explore some of the causes for this issue and provide you with solutions to fix it.

Reasons Why Your Greenworks Lawn Mower Won't Start

1. Dead Battery

The most common reason why a Greenworks lawn mower won’t start is because its battery has died or lost charge over time. This can happen if you’ve left your machine unused for an extended period or haven’t charged it correctly.

Solution: Charge your battery completely before using your machine again. If this doesn’t work, try replacing the old battery with a new one.

2. Damaged Spark Plug

Another potential cause is a damaged spark plug that prevents fuel ignition from occurring within your mower's engine system.

Solution: Replace your spark plug if it’s dirty or corroded to ensure proper fuel ignition in the combustion chamber of your engine system.

3. Clogged Carburetor

A clogged carburetor may also prevent fuel from reaching the combustion chamber in sufficient quantities leading to startup failure on electric lawnmowers as well as their gasoline-powered counterparts by blocking airflow through tiny jets located inside its body which mix air and gas together before sending them into intake manifold onto cylinder port on top of piston head where explosion take place producing power stroke needed turn blades under deck

Solution: Clean out any dirt or debris buildup within carburetor passages by removing all components first then running compressed air through each area until cleared up completely.

4 . Faulty Starter Solenoid

If neither solution has worked so far in getting rid off starting problem then there’s possibility faulty starter solenoid may be causing this issue which responsible for transmitting electrical current from battery to starter motor to engage engine turning over blades on deck.

Solution: Check if starter solenoid is malfunctioning by using multimeter capable of measuring voltage drop across terminals while cranking machine over several times., If you notice significant voltage drop when engaging switch then replace the unit after confirming against manufacturer’s guidelines.

Tips To Avoid Starting Problems In Future

Some additional tips can help avoid starting problems in the future:

  1. Store your Greenworks lawn mower indoors, out of harsh weather conditions that could cause internal damage.

  2. Keep your battery charged regularly so it always has enough power to start up quickly and efficiently without fail.

  3. Use only fresh fuel to prevent clogs in carburetor and other components from old gasoline or ethanol blends with high percentage of water making worst situation worse as they attract more moisture leading rust corrosion within engine system parts like cylinder head, valves etc..

4 . Regularly check spark plug condition changing every season at least once if needed too much combustion deposits buildup around its electrodes making harder start next time around.


In conclusion, there are several reasons why a Greenworks lawn mower won't start ranging from dead batteries and damaged spark plugs,to clogged carburetors or faulty starter solenoids.. But with proper maintenance practices in place such as regular cleaning , charging fully before use, using fresh fuel appropriate for seasonal changes (blends containing little ethanol) checking all components thoroughly each season those issues can be easily avoided resulting longer lifespan increased performance overall improved experience for users trying get their work done right first time everytime!


Why won't my Greenworks lawn mower start?

There are several reasons why your Greenworks lawn mower may not start. Firstly, check the fuel level and ensure there is enough gasoline in the tank. If the fuel level is fine, make sure that the spark plug is clean and properly gapped as a dirty or worn-out plug can cause starting problems. If these two things are okay, it’s possible that a clogged air filter could be preventing air from reaching the carburetor which would stop your engine from starting.

Another reason for failure to start could be due to issues with th eignition system or loose electrical connections. Ensure that all wires are securely connected before attempting to diagnose any ignition problems further.

Lastly, if you have not used your mower for an extended period of time then it might just need some basic maintenance such as oil change or cleaning of filters before it starts up again.

To keep your Greenworks lawnmower running smoothly and avoid problems with starting up – regular maintenance checks both seasonal (before putting away for winter etc.)  and routine (checking oil levels) should be done at least every six months.
