Types of Electric Lawn Mowers
Electric lawn mowers are generally categorized into two types: corded and cordless. Each type has its advantages and considerations, and each works slightly differently. We summarized the key differences in the table below:
| Electric Mower | Advantages | Considerations |
|---|---|---|
| Corded |
|
|
| Cordless |

Corded Electric Lawn Mowers
Corded electric lawn mowers are powered by electricity, through a power cord plugged into an outlet.
Advantages
- Unlimited Run Time: As long as the mower is plugged in, it has a consistent power supply, so it can run uninterrupted indefinitely. This makes it ideal for larger lawns that may take some time.
- Lightweight: Without the need for heavy batteries, corded mowers are typically lighter, making them easier to maneuver.
- Lower Cost: Corded models are usually more affordable than cordless mowers, both in terms of initial purchase and long-term maintenance.
Considerations
- Cord Management: The power cord requires careful management to avoid tangling or accidentally cutting it while mowing.
- Limited Range: The range of operation is restricted by the length of the power cord. This can be limiting for very large yards. You could consider using extension cords, but they present new challenges.
- Depends on Power Outlets: You need to have accessible outdoor (or indoor but reachable) power outlets to use a corded mower, which may not be convenient.
Cordless Electric Lawn Mowers
Cordless electric lawn mowers run on rechargeable batteries. These battery-powered electric mowers are ideal if you value increased mobility and ease of use.
Advantages
- Mobility and Flexibility: Without a cord, you can move freely around your yard. It's easier to mow in complex or large spaces without worrying about cord length.
- Ease of Use: Cordless mowers are straightforward to start and operate, often with a simple push-button start.
- Reduced Noise: These mowers typically make less noise than gas-powered models.
Considerations
- Battery Life: The run time is limited by the lawn mower's battery charge. You might need multiple charges or spare batteries for larger lawns.
- Charging Time: Recharging the batteries can take several hours.
- Higher Initial Cost: Cordless mowers generally have a higher upfront cost, including potential expenses for extra or replacement battery packs.
Key Components of Electric Lawn Mowers
To understand how electric lawn mowers work, it helps to know more about their various components. Here are the moving parts of electric mowers.
Motor
The motor is the heart of an electric lawn mower. It converts electrical energy into mechanical energy, driving the blades to cut the grass. There are two types of motors used in electric lawn mowers: brushed and brushless. Brushless motors are more efficient than brushed motors, produce less heat, and have a longer lifespan.
Battery (for Cordless Lawn Mower Models)
The battery provides the power needed to run the motor and blades. Most modern mowers use a 12-volt lawn mower battery. Lithium-ion batteries are more common, due to their high energy density, lightweight features, and ability to hold a charge longer.
Blades
Electric lawn mower blades are usually made of durable steel. The sharpness and design of the blades can significantly impact the mower’s performance. Regularly sharpening and balancing the blades keeps your mower cutting effectively and prolongs its lifespan.
Control System
The control system of an electric lawn mower includes the handles, switches, and safety mechanisms that allow you to operate the mower. Many models feature ergonomic handle designs for comfort and ease of use. Safety features like blade brakes and start switches help prevent accidental starts and keep you safe. Some models offer variable speed controls.
Wheels and Chassis
Mower wheels are typically made from high-quality plastic or rubber and come in various sizes. Larger rear wheels can improve stability and ease of movement on uneven ground. The chassis, often made of steel or heavy-duty plastic, supports the entire structure of the mower and protects internal components from damage.
How Do Electric Lawn Mowers Work?
Electric lawn mowers use an electric motor powered by either a battery or a direct connection to an electrical outlet. Here’s a deeper dive into how they operate.
Power Source and Delivery
Corded mowers draw power from an electrical outlet, which provides continuous operation but limits mobility. Cordless mowers use rechargeable batteries, offering greater flexibility and freedom of movement. The power is delivered to the motor, which drives the cutting blades.
Blade Mechanism and Cutting Technique
The blade mechanism in electric lawn mowers typically involves a rotating blade situated beneath the mower deck. The motor powers the blade, which spins at high speed to cut the grass. Some models feature a single blade, while others may use multiple blades for faster, more efficient cutting.
The cutting technique can vary, and most mowers also have options for mulching, bagging, or side discharge of clippings. Mulching mowers finely chop the grass and return it to the lawn as fertilizer, while bagging mowers collect the clippings for disposal.
Control Mechanisms
Electric lawn mowers are equipped with various control mechanisms for ease of use and safety. Common controls include a handlebar with a power switch or lever, which must be engaged to keep the mower running. Some models also feature adjustable height settings, allowing you to change the cutting height of the blades to suit different grass lengths and types.
Starting Mechanisms
Starting an electric lawn mower is usually straightforward and involves pressing a button or pulling a lever. This is quite different from gas-powered mowers, which often require a pull cord to start.
Speed Control
Many electric lawn mowers come with variable speed control, which allows you to adjust the mowing speed to match your pace and the conditions of your lawn. This feature can be particularly useful for navigating around obstacles or handling thicker, tougher grass. Speed control is usually managed through a dial or lever on the handlebar, providing easy access while mowing.
FAQs on How Do Electric Lawn Mowers Work?
How Long Does a Typical Battery-Powered Lawn Mower Run on a Single Charge?
The run time of a battery-powered lawn mower varies based on several factors. Most modern battery-powered mowers can run from 30 to 60 minutes on a single charge. High-capacity batteries, often measured in ampere-hours (Ah), provide longer run times. For example, our Mowrator S1 Remote Control Lawn Mower 2WD features an 18Ah LiFePO4 battery, which runs for up to 135 minutes (that’s over 2 hours!) and charges fully in 90 minutes or less!
Are Electric Lawn Mowers as Powerful as Gas Mowers?
Modern electric lawn mowers, especially more advanced models, can just about match the power output of gas-powered mowers. Many electric mowers now feature high-torque motors and advanced battery technology that deliver performance comparable to that of gas-powered counterparts, especially for typical residential use.
Can I Use an Electric Lawn Mower in Wet Conditions?
No, you shouldn’t use an electric lawn mower in wet conditions. Corded or cordless, water and electricity (or battery power) can be a dangerous combination. Also, wet grass can clump together and make it more difficult to mow. To avoid problems, wait for the grass to dry before mowing.
