The most likely reason as to why your mower shuts off when you turn the blades on is due to an issue with the engine. It may be that the engine is overheating or that the fuel supply has been disrupted.
The engine is the power source for the blades and when it fails to provide the correct amount of power, the blades will not engage. Additionally, the power switch or safety switch may have been tripped and it’s preventing the blades from turning.
If the blade itself is blocked in any way (such as by mud, grass, twigs, or debris) it may not get enough power from the engine and it will shut the engine off. You should inspect your mower to see if there is any debris or clogging restricting the blade from turning, and if there is, then remove it and try again to see if the mower will turn on.
If that does not help, then you should have a professional technician inspect the mower for any further problems that may be causing it to shut off.
Why does my Husqvarna lawn mower keep shutting off?
If your Husqvarna lawn mower keeps shutting off, there are a few potential causes you should investigate. The first is the spark plug. Check your spark plug to make sure it is clean and in good condition.
If it is damaged or clogged with dirt, it will not be able to ignite the engine, resulting in it shutting off. You should also check the air filter. Over time, the filter can become clogged with dirt and debris, preventing air flow and leading to a weak spark.
Clean the filter or consider replacing it if it is severely clogged. It is also possible that the gas tank is clogged, causing fuel to not get to the engine. Remove the gas tank from the lawn mower and use a tube brush to clean out any debris.
Once you replaced the plug, cleaned the air filter, and cleaned out the tank, you should try starting the lawn mower again. If it is still not working, it is likely a more serious issue that requires professional repair.
How do you bypass a seat safety switch?

How do you adjust the PTO clutch on a lawn mower?
Adjusting the PTO clutch on a lawn mower is a relatively easy process. First, you will need to locate the PTO clutch, which is typically located on the left side of the mower. Once you have located it, you will need to remove the necessary nuts and bolts that are keeping the clutch in place.
After the nuts and bolts have been removed, you will be able to access the adjustment screws. To make the adjustment, you will need to turn the adjustment screws clockwise to lessen the load on the clutch, or counterclockwise to increase the load.
It is important to note that each counterclockwise turn should reduce the load by less than one-quarter turn. If you turn the screws too much, you may cause permanent damage to the clutch. Once the adjustments have been made, be sure to reattach the nuts and bolts securely.
Lastly, you should always test the clutch after making an adjustment to ensure that it is working correctly.
What would cause a mower to start but not stay running?
A mower that starts but does not stay running could be experiencing a few different problems. One possible cause could be that the fuel in the tank has gone bad, is water-contaminated, is not being properly drawn into the carburetor, or is too old.
Additionally, the carburetor could be clogged or the spark plugs could be dirty or too worn, preventing them from firing. The air filter could also be too dirty or clogged, which can cause the engine to run rich and make it difficult for it to stay running.
Finally, low oil levels can cause the engine to struggle and shut off, so checking the oil levels and ensuring they are filled correctly is always a good place to start.
Why does my lawn mower only run for a few seconds then dies?
This is likely caused by a fuel system problem–either the fuel is not making it to the engine, or the engine is not getting enough fuel to keep running. It could be a number of things.
One potential issue is the fuel tank vent. If this is blocked, the tank won’t let air in and the fuel won’t be able to flow out, which will cause the engine to stall after a few seconds. Make sure the tank vent is not blocked.
Another potential issue could be the fuel filter. If the filter is blocked it will stop the fuel flow to the engine, causing the engine to die. It’s a good idea to check and replace the fuel filter if necessary.
A third issue could be the carburetor. If the carburetor is damaged or clogged, it can prevent fuel from getting to the engine. This can also cause the engine to die after a few seconds. It may be a good idea to take the mower to a professional for a tune-up if this is the case.
It could also be an issue with the spark plug. If the spark plug is worn or damaged it may not be able to generate a spark to ignite the fuel and keep the engine running. It may be a good idea to check and replace the spark plug if necessary.
Finally, it could be a problem with the air filter. If the air filter is blocked with dirt or debris, it won’t be able to let the necessary air into the engine to help ignite the fuel. It’s important to keep the air filter clean and replace it if necessary.
By checking and replacing each of the above parts, it should help to get the mower running properly again. If you’re still unable to get the mower running after doing all of the above, it may be best to take it to a professional for further diagnostic and repair.
How do you clean a lawn mower carburetor without removing it?
Cleaning a lawn mower carburetor without removing it can be a tricky job, and one that requires some time and patience. The first step is to disconnect the sparkplug wires from the spark plugs, remove the air filter, and drain any fuel from the carburetor.
Next, remove the carburetor from the engine, taking special care to ensure that the gasket does not get detached. Once the carburetor is removed, you can spray a specialized carburetor cleaner into the small openings and around the gaskets.
Be sure to wear protective gloves, and take care to avoid breathing in any of the fumes. Once the carburetor has been sprayed, allow it to sit for several hours in order to allow the cleaner to work its way into the carburetor.
Once the cleaner has had time to do its job, you can then use an air compressor to blow out any remaining debris in the carburetor, or use a small brush or q-tip to get any remaining debris out of the small openings.
It is also a good idea to take some time to inspect the carburetor for any damages, cracks, or wear and tear. Once you are satisfied that the carburetor is clean, you can then reconnect it to the engine, replace the air filter, and replace the sparkplug wires.
After putting the lawn mower back together, you can now start it up to make sure that everything is working correctly.
