Choosing between an electric lawn mower vs a gas mower should always come down to your property and priorities. The average American lawn runs about 0.2 acres - small enough that a fully charged electric mower finishes the job without needing a battery swap.
Gas mowers handle larger properties, thicker grass, and continuous operation without the 30-60 minute runtime limits of battery mowers. Here are some of the real-world differences to consider when picking the right mower for your yard.
Electric Lawn Mowers: Pros and Cons to Consider
Pros of Electric Lawn Mowers
- Zero emissions: No exhaust fumes while mowing, better for air quality
- Quiet operation: 60-75 decibels versus 85-95 decibels for gas mowers
- Lightweight and easy to maneuver: Most weigh 40-80 pounds versus 80-120 pounds for gas models
- Minimal maintenance: Charge the battery, keep blades sharp, clean the deck - that's it, no oil changes, spark plugs, or carburetors
- Lower operating costs: Electricity costs pennies versus gas prices that fluctuate between $3-5 per gallon
The main advantages of electric lawn mowers over gas lawn mowers are that they are healthier for the environment, quieter in operation, more maneuverable, and require less maintenance.
Cons of Electric Lawn Mowers
- Limited runtime: 30-60 minutes per charge on most batteries
- Less power for tough conditions: They may struggle with thick, tall, or wet grass
- Battery degradation - Batteries lose capacity after 3-5 years; replacement costs add up over ownership
- Charging time: An electric lawn mower may take 60-120 minutes to fully recharge, interrupting work if the battery runs out.
- Smaller cutting decks: Average 22-inch width versus 30-inch for gas, which means more passes to cover the same area
Compared to a gas lawn mower, however, an electric lawn mower is less powerful, especially in challenging terrain or when dealing with tall/wet grass, and has to be charged at intervals, which may slow down big projects.
Gas Lawn Mowers: Pros and Cons to Consider
Pros of Gas Lawn Mowers
- More raw cutting power: Handles thick grass, wet conditions, and overgrown lawns without bogging down
- Longer runtime: 1-5 hours on a single tank, depending on size
- Wider cutting decks: 28-30 inch average leads to fewer passes, faster mowing on large properties
- Proven durability: Lasts 10+ years with proper maintenance
- Works anywhere: No worrying about battery charge or outlet access
- Lower upfront cost: Entry-level gas mowers start at $200-300, quality electric models begin around $400-500
In short, gas lawn mowers exceed electric lawn mowers in that they are more powerful and are better at handling thick, wet, and overgrown grass. They are also wider and are known to last longer with proper maintenance.
Cons of Gas Lawn Mowers
- High maintenance requirements: Oil changes, spark plug replacements, air filter cleaning, carburetor issues, winterizing fuel
- Loud operation: 85-95 decibels disturbs neighbors, requires hearing protection for extended use
- Emissions: Running a gas mower for one hour produces emissions equivalent to driving a car 300 miles, according to EPA estimates
- Heavier weight: Harder to push and maneuver, especially on slopes
- Fuel and oil costs: Ongoing expenses for gas, oil, and fuel stabilizers
- Storage concerns: Gas and oil can spill, fuel goes stale, and winter storage requires preparation
Electric vs Gas Lawn Mowers: Key Differences
| Factor | Electric Lawn Mowers | Gas Lawn Mowers |
| Power and Cutting | Score 4.5 for cutting evenness (Consumer Reports), motor senses resistance and draws more power, handles well-maintained lawns easily | Score 4.7 for cutting evenness, maintain consistent torque in tough conditions, excel in overgrown or wet grass |
| Run Time | 30-60 minutes per charge | 1-5 hours on a single tank |
| Refueling/Charging | 60-120 minute recharge time, can swap batteries for continuous operation ($100-300 per spare) | 2-minute refueling, no waiting |
| Noise Levels | 60-75 decibels (conversation level) | 85-95 decibels |
| Maintenance | Blade sharpening and deck cleaning only, 30 minutes yearly | Oil changes every 20-50 hours, spark plugs, air filters, carburetor care, 2-4 hours yearly |
| Cutting Width | Average 22 inches | Average 30 inches |
Electric vs Gas Lawn Mowers: Realistic Factors to Consider Before Choosing
| Factor | Choose Electric If... | Choose Gas If... |
| Lawn Size and Terrain | Under 0.5 acres (20,000 sq ft), mowing sessions under 45 minutes, need maneuverability on slopes | Over 0.5 acres, continuous mowing over 45 minutes, and needs traction on challenging grades |
| Grass Thickness | Weekly mowing keeps the grass at 2.5-3 inches | Grass reaches 4-6 inches between mowing, thick warm-season varieties (St. Augustine, Zoysia) |
| Noise and Neighborhood | Dense neighborhoods benefit from 60-75 decibels, early morning/evening mowing | Rural properties with space can handle 85-95 decibels, no local hour restrictions |
| Storage Space | Store anywhere - garage, shed, closet, no fuel smell or spill risk (avoid battery temps below 32°F or above 120°F) | Have ventilated storage away from living spaces for fuel vapors |
| Maintenance | Want push-button simplicity, minimal upkeep (30 minutes yearly) | Enjoy small engine work, don't mind seasonal maintenance (2-4 hours yearly) |
| Budget | Higher upfront ($400-800), lower long-term costs, battery replacements every 3-5 years ($150-300) | Lower upfront ($200-500), $100-200 annually for fuel/maintenance, engine rebuilds after 8-12 years |
Hybrid Lawn Mowers: A Better Option?
Hybrid mowers combine gas engines with electric motors, solving the limitations of both types. A gas engine powers an electric generator that runs the drive motors and cutting blades. This eliminates the mechanical transmission, belts, and traditional mower mechanics while providing extended runtime without battery limitations.
How Hybrid Lawn Mowers Offer the Best of Both Worlds
- Extended operation: Cover 5-7.5 acres on one tank plus charged batteries, no refueling or recharging mid-job
- Quiet when needed: Start on battery power in residential areas, switch to gas in open areas
- Reduced emissions: Engine runs at constant, efficient RPM, burns less fuel than traditional gas mowers
- Less mechanical complexity: No belts, pulleys, or transmissions to maintain, electric motors transfer power directly
- Zero-turn capability: Independent electric wheel motors enable precise control, tighter turns than mechanical systems
- Slope capability: Handle 45-degree inclines that would challenge traditional mowers; all-terrain tracks provide traction

Conclusion
The electric vs gas lawn mower decision depends on your specific situation. Electric mowers work best for properties below 0.5 acres, noise-sensitive neighborhoods, and anyone wanting minimal maintenance.
Gas mowers suit properties over 0.5 acres, thick grass conditions, and all-day operation. Hybrid systems solve both sets of limitations, and if you decide these are the way to go, the AHM range has got your back!
