Lawn mowers are an essential tool for keeping lawns well-manicured and tidy. Homeowners have two main options when choosing a lawn mower – battery powered or gas-powered. Both have their pros and cons and suitability depends on factors like lawn size, features needed and budget. We’ll compare battery vs gas lawn mowers so you can decide which is best for your needs.
An Introduction to Battery Powered and Gas Lawn Mowers
Battery powered lawn mowers run on rechargeable lithium-ion battery packs, while gas mowers have internal combustion engines that run on gasoline.
Battery mowers provide cordless convenience, quiet operation and zero emissions. However, batteries need regular recharging and may not last long enough on a single charge for larger yards.
Gas mowers have been around the longest and tend to be more powerful. But they produce emissions, require maintenance like oil changes and gas refills, and need to be started manually.
To decide between the two, weigh up your lawn conditions, required mowing time, noise and environmental factors. Also consider budget, as battery mowers tend to cost more upfront. But they have lower ongoing maintenance costs than gas mowers.
Comparing Cutting Deck Sizes
The cutting deck width determines the mower’s maximum cut swath in a single pass. Wider decks mean fewer passes to mow the lawn.
Battery mower deck sizes range from 16 to 21 inches. Smaller yards or tight spaces may only need a 16-20 inch cutting width, while larger lawns benefit from a 20-21 inch deck.
Gas mower cutting widths start at around 20 inches and go up to 30 inches for riding mowers. A wider deck size of 24-28 inches works well for bigger lawns over half an acre.
Check your lawn’s square footage and features to determine the ideal cutting deck width. Navigating around trees, landscaping and tight corners is easier with smaller mower decks.
Cutting Power and Performance
Cutting power comes from the mower motor and blade speed. Gas mowers have an edge here, especially for tougher mowing conditions.
Battery Mower Power
Battery mowers contain efficient brushless motors up to 12 amps, spinning blades at 3000-5000 RPM. Run time gradually decreases as batteries deplete. Slowing blade speed indicates it’s time to recharge.
Lower voltage entry-level models only suit smaller flat lawns. Higher voltage lithium-ion packs provide longer run times for larger yards. But steep slopes can still drain batteries faster.
Gas Mower Power
Gas mowers use stronger gasoline engines ranging from 140cc to 350cc, turning blades at 2800-3300 RPM. Engine power stays consistent until the gas tank runs low.
With more torque and faster blade speeds, gas mowers can power up inclines and handle thicker, heavier grass and weeds more easily.
But battery technology keeps improving. High-end batteries rival gas mower cutting power, though run times are still more limited.
Maneuverability and Handling
A mower’s maneuverability affects how easily you can steer and turn tight corners in your yard.
Battery Mower Handling
Cordless operation gives battery mowers excellent maneuverability without dragging cords. Lightweight models under 60 lbs make it easy to steer and pivot around obstacles.
Tight 20-22 inch turning radii mean battery mowers can tightly circle trees and landscaping beds with ease.
Gas Mower Handling
Push gas mowers are heavier, typically 90-140 lbs. Self-propelled models can help moving them along. Larger wheels aid rolling over uneven grass.
Turning gas mowers takes more muscle power. But dual front wheels give added traction on slopes. Riding mowers offer zero push effort, but need more space for turns.
For superior agility and tight turn handling, battery mowers are the most nimble option.
Cutting Features and Options
Different mower features allow customizing the cut to your lawn’s needs.

Noise Levels and Emissions
How much noise and emissions a mower produces should factor into your buying decision.
Battery Mower Noise and Emissions
Cordless electric motors operate very quietly at just 60-70 decibels. That’s less noise pollution for you, neighbors, and animals.
Battery mowers also have zero emissions. No engine exhaust means cleaner air in your yard and reduced environmental impact.
Gas Mower Noise and Emissions
Gas engines create a much louder 85-95 decibel buzz while running. Hearing protection is recommended.
Gas combustion emits air pollutants like carbon monoxide, nitrogen oxides, and hydrocarbons. Regular maintenance keeps emissions lower.
Battery mowers win hands down for providing peaceful, eco-friendly lawn care. Gas mowers work better for those needing raw power over quiet operation.
