8 Reasons Zero Turn Mower Quits When Hot: Causes And Fixed
It is possible for the lawnmower to malfunction if it gets too hot, just like any other machine. If you are only able to dedicate a few hours to work on your lawn every week, then this can be frustrating. It is possible for your lawnmower to overheat and fail when it becomes hot, and there are several reasons why this may be the case.
There are a number of things that can lead to your mower quitting when it gets hot, and some of them can be found on this list.
Usually, lawn mowers that quit when hot are caused by plugged air filters, clogged mower decks, a bad spark plug, a faulty ignition coil, bad fuel, or a plugged fuel cap. This type of problem appears when there is a clogged air filter, a clogged mower deck, or an incorrect engine oil level.
You should eliminate one cause of why your lawnmower has stopped working when hot before moving on to another when troubleshooting the likely cause of why your lawnmower has stopped working when hot. In certain cases, it may be necessary to check all possible causes in order to find a permanent solution to a problem, as there may be more than one fault to resolve. If you are wondering how to fix your mower, read on to find out how to do it
Reasons Your Lawn Mower Quits When Hot
Lawnmowers fail because of bad or old fuel
You will experience fewer fuel and engine problems by using fresh gasoline that contains low ethanol content in your mower. After running, the engine dies due to fuel restriction problems.
A gummy, sticky substance will result from the ethanol and moisture, as well as the separation of the gasoline and sinking to the bottom.
Your engine will run hot and may shut down when this solution runs through it. The octane rating of gasoline in gas-powered lawnmowers must be 87, and the percent ethanol content must not exceed 10%.
A lawn mower with a smaller engine will contain less ethanol.
Solution
Remove the fuel from your tank and place it in an approved fuel storage container using a siphon. Fresh fuel should be added to your lawn mower. Stabilize and clean your fuel by adding an additive.
My recommendation is Sea Foam Motor Treatment. You don’t have to worry about your engine being damaged by this product since it is petroleum-based. The fuel system and engine are cleaned with this product.
Carburetor Clogged with Dirt
A carburetor mixes air and fuel in the right proportions and provides the mixture to the cylinder for combustion. In the case of a faulty carburetor, improper or incomplete combustion will take place in the cylinder as a result of an incorrect mixture being prepared. A mower will not run if there is improper combustion, which leads to insufficient power being produced in the engine.
A gas tank that is left sitting for too long will produce sticky gum, which clogs lawnmower carburetors.
A carburetor consists of a series of needle valves, spray jets, springs, and floats that are all arranged inside its internal mechanism. As these components build up with a buildup of sticky gum-like materials, their smooth operation will be hampered due to their clogging.
Solution
There are a number of online tutorials available that will teach you how to clean your carburetor. It is not that easy to fix a malfunctioning carburetor, and it would be best to leave the task to the experts. Replacement is the only solution if the carburetor cannot be repaired.
Why a Lawn Mower Doesn’t Work When You Use the Wrong Oil
Air-cooled engine oils with high zinc concentrations are the best choice for lawnmowers. Cooling agents are made of zinc.
There is a difference between air conditioning in cars and air conditioning in airplanes. The engines of cars are cooled with liquids, while the engines of small engines are cooled with air. SAE30 or 10W-30 engine oil is recommended by most lawnmowers and small engine manufacturers.
When operating at higher ambient temperatures, you may have to use a different viscosity, such as 20W-50 since this is the recommended viscosity for most areas.
Your lawn mower’s engine oil should be selected according to this chart provided by Kawasaki Motors.
Overheating your engine can cause it to shut down when you run the wrong engine oil.
Solution
Whenever you find that the engine oil is incorrect, drain it and replace it with fresh air-cooled engine oil.
Fuel filter that is dirty
It prevents dirt from getting into the carburetor through the fuel filter. As a result, it is unfortunately inevitable that the fuel filter will become clogged with dirt over time, especially if you fail to keep the dirty fuel away from your engine regularly.
Fuel will not flow into the combustion chamber efficiently if the fuel filter is clogged, and the engine will stop running when the fuel cannot reach the combustion chamber.
Solution
A clogged fuel can be fixed in several ways depending on what type of filter it is, how often it is cleaned, and when it was last replaced. The following tips will help you maintain your fuel filter:
Fuel filters made of metallic materials are easy to clean.
The oil and gas industry is facing problems
As a result of oxidation and evaporation, gas stored in a mower’s tank will go bad after some days. Fuel lines and carburetor clog when gas sits in the tank for a long period of time. A clogged carburetor has already had the adverse effects discussed. Be sure to fill up a mower’s gas tank with fresh gas before you start it after it has been stored. It may be necessary to clean the fuel lines as well if there was old gas in your mower. To ensure that your mower runs smoothly, make sure the gas level is sufficient before starting it. Mowers will start alright, but stop running a few minutes after they reach a low gas level.
Solution and Oil Problems
An engine that is running low on oil will overheat and stall. It is therefore essential to check the amount of oil in the crankcase before starting the mower. Oil needs to be used correctly and changed regularly. After 25 houryou changen, we recommend changing the oil.
The lubricant is not adequate
Furthermore, oil serves as a lubricant as well as a coolant. Plugs and coils, for example, work better when it is present. It is impossible for spark plugs to operate without sufficient lubrication.
In order to determine whether there is another cause of heating in the lawn mower, check the oil level first.
Solution
- If the oil is low, add a little more.
- e oil in your car.In addition, it is recommended to change it every 50 hours if it has been used for more than 50 hours. The engine can be damaged just as much by dirty oil as it can by a low level of oil.
It is possible for a lawn mower to malfunction due to low engine oil levels
Make sure the engine oil level on your lawn mower is correct before each use. Overheating and shutting down can occur when engine oil is low. Lubrication of internal engine parts is done with oil.
There will be friction among the moving parts if there is not enough oil in the crankcase. Oil and parts can burn when this temperature is reached, resulting in significant engine damage.
Solution
If your mower does not run after you change the engine oil, you can try to correct the level and restart it. Your mower will most likely suffer extensive engine damage once it shuts down due to low oil.
Ensure the extent of the damage to your engine is determined by an experienced small engine mechanic. If your lawn mower’s oil level is low, you may need to replace the engine.
The spark plugs are faulty
An inoperable spark plug will either prevent the lawnmower from starting or cause it to stop running after just a few minutes. An electrode may be dirty or corroded, the porcelain housing may be broken, and carbon may accumulate on the ignition end of the spark plug.
Solution
Spark plugs can be cleaned if they are dirty. A broken spark plug needs to be replaced, but carbon buildup can be removed with sandpaper or a file. The gap between the new and old spark plugs should match when replacing a spark plug. There are many parts shops that sell spark plugs, and they are not expensive.
Conclusion
It is a sign that something might be wrong when you see your lawnmower heating up while it is running. Sadly, if this problem is not fixed, more parts may be damaged in the future as they will have to work harder to keep the engine running, which will result in them being damaged. If you are able to identify the possible causes of your lawnmower’s problem, you can fix it so that it continues to run when you are using it.
