- Lawn mower does not start - that's what it can be
If the lawnmower suddenly fails to start, it can have different reasons. Here you can find out how it can be and how you can get the mower started with simple emergency measures.Mowing lawn is not one of the most beautiful gardening tasks, but it has to be done after all. For some it may even be fun to do some laps with the mower. But the fun fizzles pretty fast when the lawnmower suddenly fails to start. Mostly this happens in situations where you do not have much time anyway, but the lawn is in urgent need of a cut.
And now? No panic. Often the problem can be easily found and fixed. Luckily, many lawnmowers are still built to handle the most important maintenance and repairs.
Only when nothing works and even the expert knows no advice, then maybe it makes sense to consider a new purchase and switch to a more modern device. Further developed lawnmowers come every year new on the market, as the lawn mower test on Warenvergleich.de straight shows up-to-date.
Lawn mower does not start - that's what it can be
Cause 1: Missing fuel
You may be smiling now, but it's just happened too often, so this is a must-have item.
Before you turn on the mower, you should check whether there is enough fuel left in the tank. If necessary, you simply have to add something.
Also wrong fuel can be a cause that the mower does not start anymore. Most models fuel normal gasoline, but there are also lawnmowers that need to be fueled with diesel. You are not sure? Then try no further start attempts. At worst, it could happen that the engine takes damage from it. The manual or the operating instructions provide you with detailed information on which fuel your lawnmower needs to be filled with. If you made a mistake here, then you should pump out the wrong fuel as quickly as possible and replace it with the right one.
Cause 2: Broken spark plug
The right fuel is refueled, but the lawnmower still does not want to? Maybe it's the spark plug. This could possibly be defective or heavily soiled. To get an accurate idea of this, you should take a closer look at the spark plug. The manual or the operating instructions will show you exactly where it is sitting. It also describes in detail how it can be solved.
Often it is enough if you clean the spark plug with an old cloth (without water!). Especially the contacts should be free of dirt, so that a spark can skip.
If it still does not work then it may be broken. Then you have to buy a new one. For this you will find on the existing spark plug a detailed description. It should be explicitly the same, so it fits in your lawn mower.
Cause 3: Dirty air filter
The engine of the mower needs clean air to start properly. They have an air filter. Over the years, a lot of dust, dirt and even oil accumulates in it. According to the experts from motorgeraete-stichel.de, all types of filters (paper air filters, foam air filters,...) need an all-round check after about 25 operating hours (or quarterly). Then they should be extensively cleaned or replaced at the latest.
- The dirt in paper air filters can be easily poured out. A compressor is also ideal for such cleaning work.
- For foam air filters, you can get the best results with hot water and detergent.
You'll be amazed at what it can do at startup when the air filter is free of dirt and grime again.
Cause 4: Blocked knives
You will surely wonder now, what the knives have to do with the start attempt. Watch out! If you pull on the starter pull and the blades are blocked at the bottom, the engine can not start. Often you can easily tell by pulling the cable pretty badly.
In that case you should take a look at the substructure. Often it is only old grass remains or small stones that have caught somewhere or just accumulated over time. Carefully turn the lawnmower sideways and remove all possible blockages.
But beware! According to presseportal.de, about 34 percent of all accidents in the garden are injured. The lawnmower is right at the top of the list of causes. For gasoline lawnmowers, be sure to unplug the ignition plug and, for electric lawnmowers, disconnect the power cord. This will prevent the lawnmower from starting during your maintenance and cleaning.
Cause 5: Too long service life
The winter was long and the lawnmower could enjoy a long rest. What has certainly been just as relaxed for you can lead to extreme starting problems for the lawnmower itself. If a lawnmower is left idle for too long, it can happen that it does not start immediately in the spring and may require several attempts.
Often the problem has already been resolved if you try the boot process a little more often. In some manuals even what exactly is to do if the lawnmower had a longer break.
Cause 6: Special feature of ride-on mowers
Anyone who is allowed to call a lawn tractor its own can be lucky. This makes it possible to mow large areas very quickly. What you should not forget is that riding mowers work much like a car. He is also powered by a battery. If this is empty, the engine can not start. So make sure in advance that it is fully operational.
Cause 7: Special feature of electric lawnmowers
In electric lawn mowers many of the above causes do not apply. But that does not mean that starting with an electric lawnmower can not be a problem at first.
Power is essential for an electric lawnmower. Here it can happen that the power cable has a defect or the plug is simply not properly in the socket.
If the cable has a defect, contact a specialist. From such repairs you should leave as a layman necessarily the fingers.
