Gas vs Battery Lawn Mowers
Gas and battery mowers cut grass the same way; the difference is how they are powered. Each format has well-understood tradeoffs. This page lays them out plainly — it does not declare one format best, because the right choice depends on your lawn size, terrain and preferences.
Power and cutting performance
Gas engines deliver sustained high power and are commonly used across every mower class, from small push mowers to commercial zero-turns, including the tallest and thickest grass.
Battery mowers have improved substantially and handle typical residential lawns well. Their instantaneous power is strong, but the largest and most demanding commercial machines are still predominantly gas. Voltage and battery capacity (amp-hours) are the figures that indicate a battery mower's capability.
Runtime and refueling vs recharging
A gas mower runs as long as there is fuel in the tank and can be refueled in seconds, which matters for large properties and back-to-back jobs.
A battery mower runs until the pack is depleted, then needs recharging; many owners of larger lawns keep a spare charged battery to swap in. Stated runtime varies with grass conditions and cutting load.
Noise
Battery mowers are generally quieter than gas mowers, which some owners value in residential neighborhoods and for early-morning or evening mowing. Gas mowers are louder by nature of the combustion engine.
Maintenance
Gas engines need routine upkeep: oil changes, air filters, spark plugs, fuel stabilizer or tank draining for storage, and occasional carburetor service.
Battery mowers have no engine oil, spark plugs or fuel system, so routine maintenance is reduced — mostly blade sharpening, deck cleaning and battery care. Batteries do wear over years of charge cycles and are eventually replaced.
Cost
Gas mowers often have a lower up-front price for a given class, with ongoing costs for fuel and maintenance parts.
Battery mowers can cost more up front (the battery is a large part of the price) but have lower running costs and no fuel purchases. Buying within one battery platform lets a battery be shared across tools.
Gas and battery, class by class
Every model MowerFacts catalogs in each class, split by power source: how many, and the median deck, weight and list price of each group. Gas rows show the median published engine output; battery rows the median platform voltage and pack capacity where makers publish them.
| Class | Power | Models | Deck | Output | Battery | Weight | Median price |
|---|---|---|---|---|---|---|---|
| Push / Walk-Behind | Gas | 60 | 21 in | 18.5 hp | — | 114 lb | $749 (41) |
| Push / Walk-Behind | Battery | 135 | 20 in | 40 V | 5 Ah | 59 lb | $499 (71) |
| Riding | Gas | 74 | 47 in | 22 hp | — | 611 lb | $2,999 (29) |
| Riding | Battery | 7 | 42 in | 60 V | — | 487 lb | $3,000 (5) |
| Zero-Turn | Gas | 323 | 52 in | 24 hp | — | 850 lb | $8,299 (215) |
| Zero-Turn | Battery | 32 | 48 in | 57 V | — | 617 lb | $7,399 (18) |
| Commercial | Gas | 263 | 54 in | 25.5 hp | — | 1,045 lb | $12,349 (130) |
| Commercial | Battery | 18 | 56.5 in | 56 V | 348 Ah | 1,246 lb | $23,779 (10) |
A dash means no model in the group publishes the figure. The price column counts the models with a published list price in parentheses. Stated run times are on each battery model’s own page; makers quote them under their own conditions, so they are not pooled here.
What each class costs
Manufacturer list prices across the 580 models with a published price, by duty class.
| Class | Models priced | Lowest | Median | Highest |
|---|---|---|---|---|
| Residential | 152 | $190 | $689 | $44,000 |
| Prosumer | 90 | $2,299 | $4,599 | $20,000 |
| Commercial | 338 | $1,499 | $11,899 | $85,499 |
List prices exclude tax, freight and dealer setup, and dealers set the final figure. Machines sold on a dealer quote aren’t counted here.

FAQ
Are battery mowers as powerful as gas mowers?
For typical residential lawns, modern battery mowers cut comparably to gas models. For the largest properties and commercial daily use, gas still dominates the widest, highest-output machines. Compare the specifications of specific models rather than the format alone.
Do battery mowers need less maintenance than gas mowers?
Generally yes. Battery mowers have no engine oil, spark plugs or fuel system, so routine maintenance is limited mainly to blade sharpening, deck cleaning and battery care. Gas mowers require periodic engine service.
Which is cheaper, gas or battery?
Gas mowers often cost less up front for a given class but add fuel and maintenance costs over time. Battery mowers can cost more initially, largely due to the battery, with lower running costs. Total cost depends on usage and how long you keep the mower.
