Learning how to start an electric lawn mower is the first step to a perfect lawn. The process is generally straightforward, but knowing the exact steps for your model ensures a safe and smooth start every time. This guide will walk you through everything you need to know.
Electric mowers come in two main types: corded and cordless (battery-powered). While both are simpler than gas mowers, their starting procedures differ slightly. We will cover all the essential steps, safety checks, and troubleshooting tips.
Let’s get your mower running.
How To Start An Electric Lawn Mower
Before you press any buttons or pull any levers, a few preliminary steps are crucial. These steps protect you, your property, and the mower itself. Rushing this part can lead to accidents or damage.
Always begin by reading your owner’s manual. It contains model-specific instructions and safety warnings that are vital. If you’ve lost your manual, you can usually find a digital copy on the manufacturer’s website.
Essential Pre-Start Safety Checks
Never skip your safety inspection. It takes just a minute and can prevent serious injury. Make this a consistent habit before every single mowing session.
First, clear the mowing area. Walk the lawn and remove any sticks, stones, toys, or garden hoses. These objects can become dangerous projectiles if hit by the mower blade.
Next, dress appropriately. Wear sturdy, closed-toe shoes with good grip. Long pants and safety glasses are also highly recommended to protect your legs and eyes from debris.
Finally, check the mower itself. Ensure the blade is sharp and securely attached. A dull blade tears grass, leading to a brown, unhealthy lawn. Look for any obvious damage to the mower’s body or cord.
Understanding Your Mower’s Components
Familiarizing yourself with the key parts makes the starting process intuitive. Here are the common components you’ll interact with:
- Safety Key or Switch: A removable key or a switch that acts as a safety interlock. The mower will not start without it.
- Start Button or Lever: The primary control you press or pull to engage the motor.
- Bail Lever (Deadman’s Switch): A long bar on the handle you must hold down to keep the mower running. Releasing it stops the blade instantly.
- Battery Port/Charger: For cordless mowers, the slot where the battery pack inserts.
- Power Cord: For corded mowers, the thick, outdoor-rated extension cord.
- Height Adjustment Lever: Sets the cutting height for your grass.
How To Start A Cordless Battery-Powered Lawn Mower
This is the most common type of modern electric mower. The process is typically very simple, but requires a charged battery.
First, ensure your battery is fully charged. Most batteries have an indicator light on them or the charger. A weak battery may not provide enough power to start the motor.
- Insert the safety key into its designated slot. This is often located on the upper handle or control panel.
- Install the battery pack into the mower’s battery port. Push it firmly until it clicks and locks into place.
- Locate the bail lever on the handle. This is the long bar you will hold during operation.
- While firmly holding the bail lever against the handle, press the start button or pull the start lever. The motor should begin immediately.
- Continue holding the bail lever to keep the mower running as you begin to cut.
If the mower doesn’t start, don’t panic. Check that the battery is properly seated and the safety key is fully inserted. The bail lever must be held down completely before the start button will work.
How To Start A Corded Electric Lawn Mower
Corded mowers are often more powerful and never run out of charge, but they require careful cord management. The starting sequence is slightly different.
You must use a heavy-duty outdoor extension cord rated for your mower’s amperage. A light-duty indoor cord is a fire hazard and can damage the mower motor.
- First, plug the extension cord into a grounded outdoor GFCI outlet. These outlets have “Test” and “Reset” buttons and protect against electrical shock.
- Next, plug the mower’s power cord into the extension cord. Ensure the connection is snug and kept away from damp areas.
- Insert the mower’s safety key if it has one. Some corded models use a simple switch instead.
- Position the mower on your lawn, carefully laying the cord behind you, away from the cutting path.
- Hold the bail lever against the handle and press the start button. The mower should start right away.
Always be mindful of the cord’s location. Mow in a pattern that keeps the cord behind you, and frequently check to ensure you haven’t run over it. Cutting the cord is a serious danger.
Special Considerations For Push-Button Start Models
Many modern mowers feature a simple push-button start. For these, the sequence is often: insert key, install battery, hold bail, and press button. There’s no pulling required. The button may need to be held for a second before the motor engages.
Special Considerations For Lever-Start Models
Some mowers use a lever you pull toward you to start. The principle is the same: safety key and bail lever must be engaged first. Pull the start lever firmly and smoothly. A hesitant pull might not activate the switch correctly.
Step-By-Step Starting Procedure For All Mowers
Here is a universal checklist that combines all the steps above. Following this order will cover nearly every electric mower model.
- Prepare the Lawn: Clear debris and check for obstacles.
- Prepare Yourself: Wear proper footwear and eye protection.
- Prepare the Mower: Check the blade and set the cutting height.
- Power Connection: For cordless, insert a charged battery. For corded, plug into a GFCI outlet with a proper extension cord.
- Engage Safety: Insert the safety key or switch it to the “on” position.
- Grip the Handle: Firmly hold the bail lever (deadman’s switch) against the handle.
- Initiate Start: Press the start button or pull the start lever while continuing to hold the bail.
- Begin Mowing: Once the motor is running, you can start moving forward, maintaining pressure on the bail lever.
Why Won’t My Electric Lawn Mower Start?
If your mower fails to start, work through this troubleshooting list methodically. Most issues have a simple fix.
- No Power (Cordless): The battery is not charged, not fully inserted, or is faulty. Try charging it or testing it in another tool.
- No Power (Corded): The outlet may be tripped. Press the “Reset” button on the GFCI outlet. Check that the extension cord is not damaged.
- Safety Key Not Engaged: The mower will not start without the key. Ensure it is fully inserted and not worn out.
- Bail Lever Not Held: You must hold the bail lever completely against the handle before and during the start attempt.
- Faulty Start Switch: The button or lever itself could be broken. This may require professional repair.
- Motor Overload Protection: If the mower was stopped by a thick patch of grass, the thermal protector may have tripped. Wait 10 minutes for the motor to cool down before trying again.
- Blade Obstruction: Grass clippings or debris may be jammed around the blade, preventing it from spinning freely. Disconnect power and carefully clean the deck.
Best Practices For Safe Operation
Starting the mower is just the beginning. Following safe operating practices ensures you finish the job without incident.
Always mow in dry conditions. Wet grass can clump, cause slipping, and poses a severe electrical shock risk with corded mowers. The grass will also cut more cleanly when dry.
Mow across slopes, not up and down, to maintain stability. If you have a steep hill, consider using a trimmer instead. A slipping mower is very dangerous.
Never remove safety devices like the bail lever or blade guard. They are there for a critical reason. Also, never reach under the mower deck while it is plugged in or has the battery installed.
Maintenance Tips To Ensure Easy Starting
Regular maintenance keeps your mower in top condition and prevents starting problems before they begin. A little care goes a long way.
After each use, clean the underside of the mower deck to prevent grass buildup. This reduces strain on the motor and keeps the blade balanced. Store your mower in a clean, dry place.
For cordless mowers, follow the battery care guidelines. Avoid leaving the battery on the charger indefinitely or storing it in extreme heat or cold. This preserves its lifespan.
Sharpen the blade at least once a season, or more often if you hit rocks. A sharp blade requires less power from the motor, making starting easier and giving you a healthier lawn.
Periodically check all cables and connections for wear and tear, especially on corded models. A frayed cord needs to be replaced immediately.
Frequently Asked Questions
Here are answers to some common questions about starting electric lawn mowers.
Do You Have To Hold The Button To Keep An Electric Mower Running?
No, you do not hold the start button. You do, however, have to continuously hold the bail lever (the long bar on the handle). Releasing the bail lever automatically stops the blade for safety. The start button is only used momentarily to initiate the motor.
Why Does My Electric Mower Have A Key?
The safety key is a child-proof and theft-deterrent device. It ensures the mower cannot be started accidentally or by someone who shouldn’t operate it. Always remove the key and store it separately when the mower is not in use.
Can You Start An Electric Lawn Mower On Concrete?
Yes, it is generally safe to start an electric mower on a hard surface like concrete or a driveway. This can be a good way to test it before moving to the grass. Just ensure the area is clear and you have stable footing.
How Do I Start My Electric Mower After Winter Storage?
If you stored your mower with the battery removed, simply insert a fully charged battery and follow the normal starting procedure. For corded mowers, inspect the power cord for any rodent damage or cracks before plugging it in. It’s also a good time to clean the deck and sharpen the blade.
Is It Bad To Start And Stop An Electric Mower Frequently?
Unlike gas engines, electric motors are not harmed by frequent starting and stopping. The safety design of the bail lever encourages you to stop the blade when moving away from the mower or emptying the bag, which is perfectly fine for the motor.
