10 Common Toro Lawn Mower Problems & Solutions
Maintenance of your lawn equipment on a regular basis is one of the most effective ways to prevent problems and extend its life.
No start on bull mower
Often times, when your Toro lawn mower does not start, it is because of a restriction in either air or fuel flow. There are certain restrictions that prevent the engine from receiving enough air and gas during the starting process.
Getting to the point
A tank of gas is empty
We have an empty fuel tank in our vehicle. Fresh fuel should be added to the tank.
Fuel that is old or inedible
The fuel in your vehicle breaks down over time, becoming less efficient as a result and more susceptible to clogging as a result.
The fuel tank should be drained and a fresh fill of fuel should be poured into it. The most effective way to stabilize your fuel and clean your fuel system is to use a fuel additive like Sea Foam. Make sure that you use the right fuel for your vehicle.
Fuel cap that has a fault or is clogged
There is a possibility that the vent in the cap can get clogged and create a vacuum that restricts the flow of fuel to your tank.
If the vent is clogged, you can try to clear it using a thin piece of wire. It may be necessary to replace the cap if it becomes damaged.
Having a problem with your spark plug
Irregularly gapped spark plugs; excessively dirty spark plugs; spark plugs with broken or extremely dirty electrodes.
Make sure it is gapped according to the manufacturer’s specification, secure the connections, and replace the spark plug with a replacement one.
Filter in the air conditioner is plugged
Air flow can be blocked by dirt and grass clogging the air filter and preventing it from working properly.
Clean the filter by removing it and cleaning it thoroughly. In the event that the filter is damaged, it will need to be replaced.
Filter on the fuel line has become plugged
There will be a restriction in fuel flow if a fuel filter is dirty.
Fuel filters should be replaced as soon as possible
Carburetor that is dirty
Carburetors can become clogged and dirty if ethanol deposits form inside the carburetor, which is a result of using contaminated fuel and installing substandard fuel.
In order to clean the carburetor, you will need to remove all of its components. If an item needs to be replaced, it should be replaced.
When you mow, you lose power
What causes this and how to fix it:
- Clean or replace a dirty air filter.
- Raise lawn mower cutting height to cut tall grass
- Remove or clean dirty spark plugs.
- Ensure your lawn mower deck is clean by cleaning the underside with a brush.
- The blade of your lawn mower should be sharpened or replaced if it is dull, bent, or loose.
Problems with air filters
As you may not know, airflow is one of the most significant things that keeps your Toro mower engine running smoothly. Furthermore, it’s a no-brainer that these tools are exposed to a variety of elements and weather that are capable of clogging up the air filters with dirt and grass, so seeing them clogged up is not a surprise.
When the air filter on your Toro lawn mower becomes clogged, the engine could overheat and be damaged as a result.
Result
It is a preemptive measure that our team would recommend for you that you regularly check the air filter in your car. This is because you do not want that to happen.
The air filter housing should be removed from the filter. The filter should be tapped continuously against a sturdy wall or surface in order to get rid of as much dirt as possible. The air filter cover should be able to be removed if you turn it clockwise once you have made sure that it is locked. Nevertheless, before following these steps, it is critical to remember that the spark plug wire must be disconnected.
Using a lawn mower jack or any other tool available, lift the paper air filter after it has been cleared of debris and dirt. This will enable you to check if there is any light shining through the paper. The most effective way to improve the efficiency of your mowing operation is to replace the air filter if it is not working.
Carburetor that is dirty
Long-term storage of gas in the tank can harm the carburetor, as the gum-like substance that forms when gas is stored in the tank for a long period of time clogs the carburetor. There are several problems associated with clogged carburetors. A clogged carburetor can fail to provide a fuel-air charge to the combustion chamber, which means that the mower is unlikely to start or will perform less efficiently. As a result, you should clean a dirty carburetor at the earliest possible time in order to avoid further damage.
Cleaning the carburetor using a solution
After removing the screws that hold the carburetor in place, the first step is to take the carburetor out of the Toro lawn mower engine. Afterwards, disconnect it from the fuel line that runs to the carburetor. While you are working on the carburetor, you need to make sure that the fuel valve is closed so that you can avoid spills. The carburetor may need to be wiggled in order to be removed from the engine.
It is now time to open the carburetor, which is the next step in this process. When you remove the carburetor’s top cap, you will be able to see the spring, which is the throttle slide attached to the carburetor, which can now be removed.
Disassemble the carburetor’s upper cap by unscrewing the four screws on the top and taking it apart. In the float bowl, you’ll see that the float has a dusty float stuck to it. However, you don’t have to clean it yet, just make sure it is clean.
After that, remove the float pin and place it in a small container with the other parts that were removed along with the float pin. Make sure to remove the main jet, the pilot jet, as well as the float needle valves and gaskets as well as the O-rings and gaskets carefully.
Ignition defect
As the fuel-air charge is being introduced into the combustion chamber, the spark plug provides a spark for the ignition of the charge. It is likely that your Toro lawnmower will have less power if the spark plug is faulty, as the fuel-air mixture will not ignite perfectly, causing the engine to lose power. A spark plug that is too damaged will not allow your mower to start if it is damaged too much.
Result
The spark plug can be removed by first disengaging the spark plug cable, and then taking out the plug with a wrench after having disconnected the lead. Make sure that the plug is free of moisture and carbon deposits around the electrodes by inspecting it closely.
You can clean the spark plug by rubbing it with a rug and allowing it to dry. By using a metal file or sandpaper, you will be able to get rid of carbon deposits on the surface. Using a feeler gauge, you should be able to measure the gap between the spark plugs.
In the Toro user manual, a standard plug gap is listed which should be set to match the gap specified in the user manual. If there is a gap that is too small or too large, you should also adjust it accordingly. A broken spark plug insulator sheath should be replaced with a brand-new one if the sheath on the plug is damaged.
An issue with the battery
Checking the battery level on your lawn mowers can help you figure out whether or not they are working properly if they are operated by electric ignition switches. There may not be any knowledge of this, but any Toro dealer will tell you that a defective battery will not allow the unit to start.
Result
Your battery is still charged if you see a yellow and red light flashing on the indicator on the front of your phone. In order for you to know that your phone has been fully charged, you need to see the green light once it appears. The only thing you need to keep in mind is that it will take some time before your lawn mower battery reaches full charge.
As a matter of fact, it is a moderately inexpensive part that needs to be replaced. Therefore, you can rest assured you’re in good hands if this is the only issue with your mower.
Bull smokes out of the mower
You can set the ratio between the gasoline and air mixture in the carburetor of the lawn mower. As a result of not getting enough air into the carburetor, the mixture will contain a higher proportion of gasoline. This will result in black exhaust fumes emerging from the carburetor. The carburetor may not receive enough airflow into it if an air filter that is dirty or clogged is blocking airflow into it.

Steps to troubleshoot your computer quickly
- Start by checking and replacing the air filter.
- Oil level is next.
- To burn off any oil that may have gotten into the engine, start the mower and let it run for 5-10 minutes.
- The fact that you mow at step angles for a prolonged period of time could also cause smoke since there may be a leak of oil as a result.
There is a vibration coming from the bull mower
As a result, this most often indicates that the mower blade is damaged or out of balance, which could lead to the problem. When a blade spins, it experiences vibration due to an uneven distribution of weight at either end of the blade (the same way that a washing machine with an unevenly distributed load will knock around and cause more noise than normal as it spins).
Result
There may be an issue with the blade of your mower causing it to vibrate excessively. Therefore, you should inspect the blade for any damage and test its balance to see if the problem is caused by the blade. In the event that it is damaged, it should be replaced. The blade can be sharpened in order to bring it back into balance or the blade can be replaced if it is out of balance.
A gas leak has been detected on a bull mower
The float bowl gasket might be dried out or missing if fuel is leaking from the bottom of the carburetor. Please check the connections that connect the fuel filter to the filter housing as well as to the fuel filter itself. It is recommended that you replace any fuel lines that are cracked or dry. The fuel line should not be cut and reattached after a piece of it has been cut off.

An overview of the general systematic approach
- Gas tanks should be drained.
- Make sure the gas tank is taken out of the car.
- Find the problem and clean the gas tank.
- Sand or knife the plastic pieces.
- The wrecked area needs to be measured.
- The damaged area should be heated.
