A lawn mower uses between 500 and 2000 watts per hour, although on average, your lawn mower will use around 1000 watts per hour. Your lawn mower's wattage per hour will heavily depend on the type of lawn mower you use and how overgrown your grass is. If you're planning to move from petrol mowers to electric lawnmowers and want to know how much it will cost, you've come to the right place.
Mowrator is an industry-leading remote-controlled lawnmower company that's here to explain lawn mower costs. We'll cover the watts per hour each type of lawn mower uses, factors that affect electricity consumption, and how to calculate your lawn mower costs at home.
Key Takeaways
- Electric lawnmowers use between 80 and 1800 watts per hour, with typical models averaging around 1000 watts per hour, depending on their type.
- Power consumption is influenced by factors such as battery type, grass conditions, motor efficiency, and environmental conditions.
- You can calculate your mower's electricity cost by converting its wattage to kWh and applying your local rate. For example, a 1500W mower could cost about 49 cents per hour.
How Much Electricity does A Lawn Mower Use?
A lawn mower uses between 80 and 1800 watts per hour, depending on the type. Corded and riding lawnmowers often demand more electricity, while cordless mowers with batteries, such as remote-controlled, robot, and push mowers, tend to use less. Below, we've outlined a range of watts per hour you can expect your lawn mower to consume.
| Type of Lawn Mower | Electricity Usage |
|---|---|
| Corded Electric Lawn Mowers | 1200 to 1800 watts per hour |
| Cordless Lawn Mowers | 500 to 1400 watts per hour |
| Riding Lawn Mowers | 1800 watts per hour |
| Robot Lawn Mowers | 80 watts per hour and around 2 to 6 watts when idle |
| Remote Control Lawn Mowers | 900 to 1500 watts per hour |
What Factors Affect the Power Consumption of Your Lawn Mower
The battery type, grass conditions, motor efficiency, and other environmental factors can affect how much power your electric lawn mower uses. If your lawn mower is cordless, its battery is also susceptible to several factors that can shorten its battery life or increase energy usage. Let's take a look at how each factor impacts your mower in terms of performance.
Battery Type
The type of battery affects how much power your lawn mower consumes if you use cordless electric mowers. Newer, more modern batteries like lithium-ion and lithium-iron phosphate (LiFePO4) offer long-lasting performance between each recharge compared to lead-acid batteries. Batteries with higher voltage and capacity will also reduce your electricity bill overall since you need to charge them less.
Grass Conditions
The conditions of your grass will affect how much power your lawn mower uses. A thick, overgrown lawn will require your mower to work harder to cut the grass to your specifications, which uses more watts per hour. You'll often find your mower's battery capacity drains quicker when mowing in less-than-ideal conditions such as the thickness of the grass, ground firmness, and more.
Motor Efficiency
In addition to the battery and terrain, the type of motor your lawn mower has will determine its wattage per hour. For example, higher torque models will be able to handle thick grass well but require more power as a trade-off (whether you're mowing thick grass or not). The type of mower motor brushed or brushless, will also impact the power usage.
Brushless motors are more efficient and use less electricity than brushed motors.
Environmental Conditions
External environmental conditions, like temperature or humidity, also affect battery power usage and wattage per hour. In Australia, the summer heat often means that cordless battery lawn mowers need to recharge more often and perform poorer than in cooler climates. Rain, heat waves, and moisture can make affordable models cost more in the long run because of the energy cost.
How to Calculate Your Lawn Mower Electricity Costs?
You can calculate your lawn mower's electricity costs by finding its wattage, converting it to watts per hour, and then applying your electricity rate to the wattage. For example, if your lawn mower's wattage is 1500W, your kWh would be 1.5kWh. Applying the electricity rate in Australia between 32.7c and 58.9c per kWh, your total consumption per hour will be 1.5 x 32.7c = 49,05c/kWh.
If you want to maximise a single battery charge, look no further than the S1 Remote Control Lawn Mower 4WD. The lithium-iron phosphate (LiFePO4) battery in the S1 4WD allows you to mow 1.125 acres on a single charge, boasting up to 135 battery run time.

FAQs on How Many Watts does a Lawn Mower Use?
What is the best wattage for a lawn mower?
The best wattage for a lawn mower depends on your specific needs. For Australian users, a corded electric mower typically uses between 1200 and 1800 watts, while cordless models often range from 500 to 1400 watts, depending on the battery voltage and capacity.
Do lawnmowers use a lot of electricity?
No, lawnmowers, particularly electric ones, do not use much electricity compared to other household appliances. The Australian market is seeing a shift towards electric and robotic mowers, in part because modern electric lawn mowers deliver the same power as petrol mowers but with minimal electricity costs.
