Starting a Toro lawn mower can be a bit intimidating for those who have never done it before, especially if your model has a primer bulb.
While the primer bulb is a helpful feature that helps to get your mower started quickly, it can be confusing to know how to use it properly.
Let’s jump in.
How to start a Toro Lawn Mower without Primer
Here is a step-by-step guide on how to start a Toro lawn mower with a primer:
1. Make sure you have the proper fuel.
The type of fuel you use can affect the performance of your mower. Toro recommends using fresh, unleaded gasoline with a minimum octane rating of 87.
Avoid using ethanol-blended fuels, as they can cause starting and performance issues.
2. Check the oil level.
It’s important to make sure your mower has enough oil before starting it up. Refer to your owner’s manual for the correct type and amount of oil to use.
3. Set the throttle control to the “Start” position.
This is typically marked with a small “S” on the control panel.
4. Locate the primer bulb.
The primer bulb is typically a small, round button on the engine’s side or fuel tank. It may also be labeled with the word “prime.”
5. Press the primer bulb a few times.
This will pump a small amount of fuel into the carburetor, helping to get your mower started.
6. Pull the starter cord.
The starter cord is typically located near the bottom of the mower. Grip the cord with both hands and pull it firmly until the engine starts.
If the engine doesn’t start, continue to pull the cord a few more times.
7. Set the throttle control to the “Run” position.
Once the engine runs, move the throttle control to the “Run” position. This is typically marked with a small “R” on the control panel.
It’s important to note that you should only press the primer bulb a few times before pulling the starter cord.
Over-priming the carburetor can cause the engine to flood, making it difficult to start.
If you accidentally over-prime the carburetor, wait a few minutes for the excess fuel to evaporate before attempting to start the mower again.

Toro Lawn Mower Starting Problems
If you’re still having trouble starting your Toro lawn mower, there could be a few other issues. Here are a few potential problems and how to troubleshoot them:
- Dirty air filter: A dirty air filter can restrict airflow to the engine, making it difficult to start. To clean the air filter, refer to your owner’s manual for instructions.
- Stale fuel: If you’ve had the same fuel in your mower for an extended period, it may have gone stale and can no longer combust properly. In this case, you’ll need to drain the old fuel and refill it with fresh gasoline.
- Faulty spark plug: If the spark plug is damaged or not functioning properly, it can prevent the engine from starting. To check the spark plug, refer to your owner’s manual for instructions on removing and testing it.
If you’ve tried all these troubleshooting steps and your Toro lawn mower still won’t start, it may be time to take it to a professional for repair.
A qualified technician will be able to diagnose and fix any underlying issues with your mower.

How to start a Lawnmower?
Locate the starter cord – the starter cord is typically located near the bottom of the mower and is used to manually start the engine.
Grip the cord with both hands and pull it firmly until the engine starts. If the engine doesn’t start, continue to pull the cord a few more times.
Priming a Lawn Mower
Locate the primer bulb.
The primer bulb is typically a small rubber button or bulb that is connected to the carburetor or fuel line. It is usually located on the side of the engine or near the air filter.
Check the fuel level.
Ensure that there is enough fuel in the mower’s fuel tank to prime the engine. If the fuel level is low, fill it up with fresh gasoline.
Identify the prime position.
Look for a position labeled “Prime” or an icon resembling a bulb on the primer bulb itself or on the lawn mower’s control panel.
Press and release the primer bulb.
Depress the primer bulb with your finger and release it slowly. You may need to press the primer bulb several times, typically 3-5 times, to ensure fuel is pumped into the carburetor.
Repeat if necessary.
If the primer bulb doesn’t feel firm after the first few presses, repeat the process until you feel resistance when pressing the primer bulb.
Start the lawn mower.
Once you have primed the engine, follow the manufacturer’s instructions for starting your specific lawn mower model. This usually involves pulling a starter cord or using an electric starter.

How to prime a lawn mower without Primer bulb
If your lawn mower doesn’t have a primer bulb, you can still prime the engine using an alternative method called gravity priming.
Here’s how you can prime a lawn mower without a primer bulb:
Fill the fuel tank.
Ensure that the lawn mower’s fuel tank has enough gasoline to prime the engine. If the fuel level is low, fill it up with fresh fuel.
Locate the carburetor.
The carburetor is the part of the engine that mixes air and fuel for combustion. It is usually located near the air filter or on the side of the engine.
Identify the carburetor’s primer port.
Look for a small hole or a fitting on the carburetor that serves as the primer port. It may be located near the air intake or fuel line.
Cover the air intake.
Place your hand or a clean cloth over the air intake of the carburetor. This restricts the air supply and creates a vacuum effect.
Tip the lawn mower.
Carefully tilt the lawn mower so that the carburetor is facing upward. Be cautious not to tip it too far to avoid fuel leakage.
Slowly pour fuel into the carburetor.
Using a small funnel or a clean container, slowly pour a small amount of fuel into the carburetor’s primer port. Take care not to spill fuel.
Return the lawn mower to its upright position.
Once you have poured fuel into the carburetor, carefully place the lawn mower back in its normal upright position.
Start the lawn mower.
This typically involves pulling a starter cord or using an electric starter.
