What Is the Average Cost of a Lawn Mower?
Last updated October 31, 2026
Across every mower type sold to homeowners, the average cost of a lawn mower sits in the low four figures, pulled up hard by riding mowers, lawn tractors and zero-turns. The average homeowner who actually buys a walk-behind spends far less, because a push mower carries no seat, no transmission and no engine on the electric side.
The category runs from a manual reel mower at the bottom to a zero-turn at the top, so a single average describes almost nobody. Breaking the average down by type, showing what each price tier buys, and adding the running costs the sticker leaves out gives a figure you can actually use.
The average cost of a lawn mower by type
Mower prices cluster by type, and the type you need is set by your lawn before anything else. The table below shows where each type typically lands, what lawn it suits and how it is powered.
| Mower type | What the tier brings | Typical average | Best lawn size | Power source |
|---|---|---|---|---|
| Manual reel | Basic cut, no drive, no power | Lowest of all types | Under 1/8 acre, flat | Push only |
| Corded electric push | Basic cut, cord-tethered | Low | Small, close to an outlet | Corded electric |
| Battery push | Basic cut, battery pack included | Low to mid | Up to about 1/4 acre | Battery |
| Gas push | Basic cut, small engine | Low to mid | Up to about 1/4 acre | Gas |
| Corded or battery self-propelled | Wider deck, mulching plug, drive | Mid | Up to about 1/2 acre | Electric |
| Gas self-propelled | Wider deck, mulching plug, drive, stronger engine | Mid to upper-mid | Up to about 1/2 acre | Gas |
| Rear-engine rider | Seat, steering, compact deck | Four figures | 1/2 to 1 acre | Gas or battery |
| Lawn tractor | Seat, steering, wide deck, larger engine | Four figures | 1 to 3 acres | Gas or battery |
| Zero-turn | Seat, lap-bar steering, wide deck, fast ground speed | Highest of all types | 3+ acres or obstacle-heavy | Gas or battery |
| Robotic | Self-docking, no operator needed | Four figures | Any size, best with obstacles | Battery |
The figures are typical US retail prices for new residential mowers, gathered from manufacturer sites and major retailers and refreshed seasonally. Push is kept separate from self-propelled, and corded separate from battery, because lumping all electric mowers together is what makes most published ranges useless.
What each price tier actually buys
Price tiers track capability, not just size. The entry tier covers manual reel and corded push mowers, where you get a narrow deck, a basic cut and little adjustment. The mid tier is where cut quality and drive are sorted without premium extras: a wider deck, a mulching plug, a reliable start and a comfortable handle.
The upper-mid tier adds self-propulsion, a larger battery pack or a more powerful engine, and better build materials. The premium walk-behind tier brings features like electric start, a washout port, cruise control and a folding handle, which make maintenance and storage easier but do not change the cut. The rider, tractor and zero-turn tier is a different class of machine, with a seat, a steering system and a deck wide enough for large lawns.
Below a certain point you lose edge-mowing and mulching capability. Above a certain point you may be paying for features that do not change the cut. For most homeowners buying a walk-behind, the sweet spot is the mid tier, where cut quality and drive are sorted without premium extras.
Why the price varies so much
Power source, deck width and build, drive system, battery voltage and capacity, features, and rider-specific factors each change what the machine can do for you.
Power source
Corded electric is the cheapest upfront, but it ties you to an extension cord. Battery mowers carry a premium for the pack, which is a large share of the cost. Gas sits between the two and adds fuel-system complexity, with more maintenance and fuel costs over time.
Deck width and build
A wider deck and heavier steel cost more. Deck width also sets how much lawn the mower suits: a 1/3 to 1/2 acre lawn calls for a deck of 18 to 21 in, while larger lawns need a wider deck or a different machine.
Drive system
Push versus self-propelled is one of the biggest single jumps in price within a type. Self-propelled mowers pull themselves, which matters on hills or if you dislike pushing.
Battery voltage and capacity
Higher voltage and larger packs raise the price. The pack is a large share of a battery mower's cost, and a bigger pack means longer runtime: the average battery walk-behind runs 45 to 50 min per charge, enough for about 1/4 acre of flat, clear lawn.
Features
Electric start, a washout port, a folding handle, cruise control, an hour meter and universal battery compatibility all add to the price. Some make maintenance easier; others are conveniences you may not need.
Rider-specific factors
On riding mowers, engine size, transmission type, deck size and steering type (lap-bar versus steering wheel) move the price most. A zero-turn with lap bars costs more than a lawn tractor of similar deck size.
Which mower fits which lawn and what that costs
Lawn size settles the type before price enters the picture. The table below maps lawn size to the type that suits it and the price tier that type lands in.
| Lawn size | Recommended type | What that tier brings |
|---|---|---|
| Under 1/8 acre, flat | Manual reel or corded push | Basic cut, narrow deck, no drive |
| About 1/4 acre | Battery push or gas push | Basic cut, no drive, pack or small engine |
| 1/3 to 1/2 acre | Self-propelled, 18 to 21 in deck | Wider deck, mulching plug, reliable start |
| 1/2 to 1 acre | Rear-engine rider or wide-deck walk-behind | Seat, steering system, deck wide enough for large lawns |
| 1 to 3 acres | Lawn tractor | Seat, steering, wide deck, larger engine |
| 3+ acres or obstacle-heavy | Zero-turn or robotic | Seat, steering system, deck wide enough for large lawns |
Hills push you toward self-propelled or a rider regardless of lawn size, because the drive pulls the mower for you and weight matters less. A flat lawn under about 1/8 acre suits a manual reel mower, which is quiet and simple with no fuel or charging. Push and self-propelled mowers suit lawns up to about half an acre; past that point you step up to a wider deck or a different machine.
The costs after you buy
The sticker price is only the first cost. Fuel, electricity, maintenance and battery replacement add up over the years, and they vary by type.
Fuel and electricity
A gas walk-behind burns roughly half a gallon an hour, so a season's fuel is a modest annual line; a rider uses several times that. Battery and corded mowers draw only a trickle of electricity over a season, and the per-mow energy cost is cents for electric against tens of cents for gas.
Routine maintenance
Gas mowers need oil, a spark plug and an air filter, plus blade sharpening two to three times a season, which works out to every 20 to 25 hours of runtime. Electric mowers skip the engine service but still need blade sharpening.
Battery replacement
Walk-behind battery packs are a periodic cost every few years. A riding mower's battery replacement is the biggest single cost over ten years, since those packs are far larger and pricier than walk-behind packs.
The table below shows the shape of ten-year ownership by type, combining purchase and running costs.
| Type | Purchase | Running costs over 10 years |
|---|---|---|
| Walk-behind gas | Low to mid | Fuel, oil, plugs, filters, sharpening |
| Walk-behind battery | Mid | Electricity, sharpening, one or two replacement packs |
| Robotic | Four figures | Electricity, sharpening, replacement packs |
| Riding | Four figures | Fuel, maintenance, large replacement pack |
A battery mower's upfront premium is often recovered on fuel and maintenance within a few years, but a pack replacement can erase that gain. The crossover depends on how long you keep the mower.
Buying used, what it saves and what it risks
Used mowers typically sell well below new retail, with the deepest discounts on machines a few years old. Secondhand push mowers are often the cheapest way into mowing at all.
Inspect the deck for rust and cracks, the blade and spindle for play, and the engine for compression and smoke on start. On a battery mower, check the age of the pack and whether a replacement is priced in. Check the self-propelled drive, and on riders inspect the transmission and hour meter.
Walk away from a cracked deck, a seized engine, or a battery mower whose pack is at end of life and no longer sold. The used market swells when new models land, which is the same late-summer-to-fall window when new prices fall.
How to Time Your Purchase and Keep the Price Down
The best time to buy a lawn mower is late August through October, when dealers and stores work hard to move prior-year inventory before the season ends.
Robotic mowers follow the tech-sale calendar as well as the lawn calendar: summer Prime events, the early-October fall Prime event, Black Friday and Cyber Monday, plus fall clearance. Holiday sales like Memorial Day and Presidents' Day are secondary windows.
Weigh the cost of waiting: a month of overgrown grass or a season of lawn service against the fall discount. If your current mower still runs, waiting for the fall window usually pays.
The average cost of a lawn mower is a low-four-figure number across all types, while the walk-behind most homeowners buy sits far below that, in the entry-to-mid tier. Start with lawn size, pick the type, then choose the tier, and budget for the running costs, not just the sticker. Late summer through fall is when the price is best.
Frequently asked questions
Most mower buyers end up spending more than the sticker price once fuel, maintenance and battery replacement are added in.
What is the average cost of a lawn mower?
It depends on the type you need: a walk-behind for a small lawn and a rider for a large one land in completely different brackets, so the type you pick matters far more than shopping around within a type.
How much is a basic lawn mower?
A basic mower is an entry-tier machine: a manual reel or a corded push model. It cuts a small, flat lawn but lacks self-propulsion, a wide deck and mulching capability.
Does a bigger battery pack on a walk-behind mower buy you a better cut?
No. A larger pack raises the price and stretches how long the mower runs between charges, but it does not change how well the grass is cut. Cut quality is settled by the tier of the machine, not by the size of the battery, so paying for extra capacity only makes sense if runtime is what you are short of.
How much does a robotic mower cost?
Robotic mowers sit in the four-figure tier. The money buys a self-docking machine that handles obstacles well, but you still pay for replacement packs over time.
Does a wider deck on a walk-behind mower cost more than a narrower one?
Yes. A wider deck and heavier steel raise the price, so deck size is one of the things that moves a walk-behind up the price ladder. The trade is that a wider cut covers more ground per pass, which is why the mid tier pairs a wider deck with a mulching plug and a reliable start.
How much does it cost to run a mower per mow?
Per mow, electric energy costs cents, while gas costs tens of cents. The gap widens over a season, especially for larger lawns.
How much does lawn mower maintenance cost per year?
Gas mowers carry the annual cost of oil, plugs, filters and sharpening; electric mowers cut that to sharpening alone, so the gap grows the longer you keep the machine.
How much does a replacement battery cost?
There is no single figure: what you pay depends on the pack's voltage and capacity and on whether the brand still sells that pack when yours dies. A pack that is no longer made can force a new mower, so check replacement availability before you buy.
How much should I spend for a good mower?
Match the spend to your lawn: a small, flat yard is served by an entry machine, while a sloped or larger yard justifies paying for self-propulsion and a wider deck. Anything beyond that buys convenience, not a better cut.
Is a used lawn mower worth it?
It can be, if you check the machine before money changes hands. Bring a short checklist: rust or cracks in the deck, play in the blade and spindle, smoke or hard starting from the engine, and the age of the battery pack on an electric model. A mower that fails any of these is not a bargain at any price.
How long does a lawn mower last?
A maintained mower lasts many seasons. Battery packs age on their own calendar regardless of use, so a pack may need replacement before the rest of the machine wears out.
Does a self-propelled mower cost much more than a push mower of the same type?
Yes. Going from push to self-propelled is one of the largest single price jumps you will see within a single mower type, because you are paying for a drive system on top of the deck and engine or battery. That extra money buys a machine that pulls itself, which is what makes it worth considering on hills or if you would rather not push. If your lawn is flat and small, the drive adds cost without changing the cut.
