You’re probably familiar with the frustration of having to restart your riding lawn mower every time you need to stop.
But what do you do when your mower engine is seized and won’t turn over, no matter how many times you try?
We’ve compiled some tips for determining whether the engine is seized, and what to do if it is.
What Causes A Lawn Mower Engine To Become Blocked?
The engine is made up of many moving parts and when one of these parts ceases to move, the engine seizes. There are a few main reasons that this can happen:
First Reason: Lack Of Oil
One of the most common reasons for an engine to seize is a lack of oil. If the engine doesn’t have enough oil, the metal parts will start to grind against each other and eventually seize up.
Second Reason: Dirt And Debris
Another common reason for an engine to seize is when there is too much dirt or debris in the engine. This can happen if the lawnmower isn’t cleaned regularly or if it’s been stored in a dirty area.
Third Reason: Worn Out Parts
The parts of the engine wear out over time and eventually won’t work anymore. Most riding lawn mower engines have a built-in life expectancy, after which the parts will become worn out and it won’t be able to start.
Fourth Reason: Overheating
If the engine overheats, it can seize up. This is often caused by a lack of oil or by an issue with the cooling system.
Fifth Reasons: Lack Of Use
Riding lawn mowers often sit for a long period without being used. This lack of use can cause the engine to seize. In order to avoid this, it’s recommended that riding lawn mowers are started every 2-3 weeks during storage periods.
Sixth Reason: Frozen Fuel
If the fuel line becomes frozen, the engine will not be able to start. This is most likely to happen in colder climates.
Last Reason: Lack Of Spark
A lack of spark can cause the engine to stop. There are many reasons why the engine might not have any spark, including a faulty coil or worn-out ignition components.
