Toro Lawn Mower Won’t Start. It’s inevitable that after owning a Toro Lawn Mower for long enough – one day, your lawnmower will quit. Your lawnmower might not start because of several different factors and parts.
The number of options can be a little overwhelming, so it can be difficult to decide where to start.
You find that when your lawnmower is having start problems, it could be because of too much or too little fuel, an issue with the spark plug, or a failure in the electrical system.
The other reason your lawnmower does not start may be due to the fuel system being dirty, the gas cap being loose, an unplugged air filter, a bad battery, and more.

If your lawn mower stops working properly, you may need to have a spark plug replaced. You should remove the spark plug, clean it off and make sure it’s securely fastened. Not only will this allow the engine to work correctly but it will also increase the life expectancy of your lawn mower.
We explain how to repair Toro Lawn Mover if it hasn’t been stratified.
Fuel Filter Issue
It is possible that the fuel filter is clogged. Most commonly, a clogged fuel filter is caused by leaving old fuel in the riding mower.
Fuel filters can get clogged up when some of the ingredients evaporate, leaving behind a thicker, stickier substance that can clog the filter and prevent it from performing as effectively as possible.
If old fuel was left in the tank of your riding mower and/or you want to make sure this doesn’t happen again in the future, drain any remaining old fuel from your lawn mower’s tank and consider replacing your current fuel filter with a newer one.
Rewinding Spring Fault
There might be a problem with the recoil spring. Pulling and releasing the starter rope causes the recoil spring to bounce onto a pulley.
If you notice an issue with your recoil starter assembly that includes a broken recoil spring, replace it. Several different springs are available to replace a broken one.
If you want to ensure everything functions correctly, some individuals may choose to replace their entire assembly at once instead of dealing with a faulty part individually.
Malfunctioning Spark Plug
Inspect the spark plug for signs of damage. If there are cracks, missing or burned-away electrodes, or carbon buildup on the body of the plug you will want to replace it.
To determine if the spark plug is defective, use a spark plug tester that rotates and helps galvanize with voltage as well as measures resistance in ohms by moving two metal prongs close together across a gap that causes electrons to jump between them and create an electric current flow.
You should see a strong spark between the tester’s terminals when cranking your engine. A broken spark shows that you need to replace your fuel ignition system.
Bad Or Old Gasoline
The carburetor of a car may become clogged. If there is old or bad fuel in the carburetor float bowl, some of the ingredients in the fuel may evaporate over time, leaving behind a much stickier alternative.
This sticky substance can clog up the carburetor and prevent the engine from starting.
To fix this problem, try taking out the float bowl, which is on top of the carburetor itself, clean it with carburetor cleaner, and then re-insert it back into place once more.
If that doesn’t work, try rebuilding or replacing the entire carburetor altogether.
Faulty Ignition Coil
Battery Issues
Any Toro lawn mowers are fitted with electric lawn mower starters that operate on the strength of a garden tool’s battery.
Electric lawn mower starter models typically require you to charge or upkeep batteries at least twice a year and sometimes more if you live in areas that have temperamental weather, such as high heat or low temperatures.
If your Toro lawn mower is not starting and is still under warranty, check the fuses. Or if your battery died or has significantly diminished from its original power supply capabilities, you may need to purchase a new electric starter for it.
Unreliable Safety Switch
If a safety switch on your Toro lawn mower fails, you may experience some problems operating the mower.
For example, if the switch isn’t working properly, the mower wouldn’t start because one of its safety mechanisms would have failed.
Before repairing anything, test the switches using a multimeter to see if they give off an electrical current when activated or due to pressure or any other reason.
However, you might have to temporarily turn the switch off in order to identify the problem with it.
If you do this, make sure you pay close attention so as not to trip over anything or get caught up with anything else that might injure you as well.
