JUST HOW MUCH Does It Cost to use a power Lawn Mower?

A Ryobi battery powered push mower.

Between your increasing cost of gas and the wide selection of electric lawn mowers in the marketplace now, you could be curious just how much it costs to possess and operate one in comparison to a gas model. Heres what you ought to know.

What Were Comparing: Push Mower vs. Push Mower

Electric mowers attended quite a distance in just a brief couple of years and there’s quite a selection of them available. You will discover from petite and inexpensive 13 push mowers completely around 54 zero-turn riding mowers ideal for mowing multiple acres.

Just as much as wed want to compare everything over the whole selection of the electric lawn mower market, that could get this to article a wee bit long to learn in a sitting. Instead, were likely to concentrate on comparing the most typical sort of lawn mower when applied to the average lawn. For American readers, the most typical mower type may be the push mower, and the common lawn size is just about 25 % of an acre.

In addition, were also limiting our comparison to battery-powered electric mowers and excluding corded electric mowers. Even yet in small yards, corded mowers are a fantastic hassle and battery-powered mowers are actually so cheap and efficient that theres just no reason to work with the nonsense to be tethered to the wall of one’s garage.

If youre interested in larger mowers and larger lawns, dont worry. Just how were comparing gasoline-powered push mowers to electric push mowers could be easily adapted to other sizes. The overall concepts will be the same.

How Operating Costs Compare AS TIME PASSES

When you compare operating costs, its not only about how exactly much it costs to charge a power mowers batteries vs. filling the vehicle’s gas tank on a normal mower. You can find several extra variables at play that tip the scales and only the electric mowerespecially for folks with small urban and suburban lawns.

We wont be comparing the price of the mower itself. The expense of basic electric push mowers and basic gasoline push mowers are on parity now (around $200-300,) and the purchase price scales pretty evenly in to the premium model territory, too. You start with the premise that you’ll require a mower for the average lawn, were likely to build out the operating cost as time passes from there.

Our stand-in for the common electric push mower would be the Ryobi 40V Brushless 20 Cordless Push Mower. Its currently a house Depot best seller, frequently for sale for $249, and the 6.0A 40V battery offers a comparable run time because the small vehicle’s gas tank on a similarly sized gasoline push mower. Youll get about 45 minutes of run time from the battery and about 45 minutes of run time from the tank of gas on your own average push mower.

Cost Per Mow

First, lets consider the cost per mow using our average quarter-acre yard as a reference point. Well look at other related costs in an instant.

Mowing a Quarter-Acre with a Gas Push Mower

Since there is a respectable amount of variability between gas push mowers with regards to engine size, how well the engine is tuned, how thick or wet the grass is, and such, we are able to talk when it comes to averages.

The common push mower tank is 0.25 gallons and really should last for roughly half an acre worth of mowing, at the very least. With the existing gas prices sitting at a national average of $5 per gallon in June 2022, which means were spending $0.63 on fuel for each and every quarter acre. Even though gas prices were to tumble to half that price, completely right down to $2.50 a gallon, your cost per quarter acre would be $0.33.

The Ryobis 6.0A 40V battery has enough juice to mow 25 % of an acre twice per charge. The capability of a 6.0A 40V battery is 240Wh and at the national average energy price of $0.14 per kWh in June 2022, that computes to $0.03 per charge.

If youre interested in the math on that, have a look atour guide to calculating battery charging costswe even used this exact battery for example if you need to start to see the math!

Based on the cost of gasoline, its safe to state that youre spending 1/10th to 1/20th of the total amount on fuel when youre refueling lithium-ion batteries from the wall socket rather than pouring gasoline in a tank.

Being an aside, you want to note that most of the estimates youll find online for the expense of charging a power lawn mower are wildly outdated or simply plain inaccurate. Theyre either referencing old battery technology that has been a lot more inefficient and cost more to chargeor theyre predicated on significant misunderstandings about how exactly much energy is stored in the battery (and necessary to charge it).

The extremely low priced of charging today’s lithium-ion push mower sounds almost absurd, but we assure you that it certainly does cost pennies to mow (and weve been doing this all season).

Ongoing Maintenance

Just how much it costs to fill the tank up or charge the battery is a part of the operating costs to take into account. Theres a substantially higher ongoing maintenance cost of a gasoline engine.

Weren’t like the cost of replacing or sharpening the mower blade within the ongoing costs here, or elsewhere in this article, because youd do this whatever sort of mower you’d.

Yearly Maintenance Costs: Gasoline Push Mower

Along with fueling your gasoline-powered mower, additionally you need to keep up with the engine itself. Which includes changing the oil in the beginning of the mowing season and also every additional 50 hours of runtime within the growing season.

Given folks are a little lax on that and 50 hours will be a lot of mowing for a little yard, lets say you change the oil once. Small mower engines usually take around 15-18 oz. of oil roughly. A 32 oz. container of small engine oil runs $6-10, so its safe to state youll spend at the very least $3 a season on oil changes.

Additionally you have to replace the air conditioning filter at least one time a season, too, which tacks on around $5-10. (The foam filters are technically washable and reusable, but in the event that you browse the manufacturers recommendations, they often encourage one to just replace them.)

Youre also likely to replace the spark plug once a season. (We wont turn you into the small engine protection agency in the event that you dont, but assuming you treat the engine right, itll set you back $3 a season for a fresh spark plug.)

So assuming you hit the essential maintenance checkpoints to do all that at least one time a season, youre spending at the very least $15 roughly each year on maintenance.

Invest the the mower right into a shop to obtain it tuned up every spring, the tuneup can cost you $50-75, normally, and include all the above and morethough few folks choose engine tuneups on small push mowers.

Yearly Maintenance Costs: Electric Push Mower

Boy, that is going to be considered a short section. Sure, you nevertheless still need to sharpen or replace the mower blade as needed, and you also should do basic cleaning like washing stuck on grass off the inside of the mower deck, however the similarities between gas push mower and electric push mower maintenance end there.

In comparison to a gas mower, a power mower is unbelievably simple. The electric mower might appear to be, in form factor at the very least, a normal mower. But inside its virtually only a big ol electric battery-powered fan that occurs to possess super sharp blades. Theres no engine, oil, air-intake, or spark plug. Its virtually a battery, a switch, and motor. Apart from the blade itself, you can find no user-serviceable parts, and you also wont be replacing any internal pieces or taking the mower apart to tinker with it.

The yearly operating cost, blade sharpening aside, is bound to how much cash you may spend charging the battery.

Projected Costs AS TIME PASSES

Its tricky to choose an excellent year mark to extrapolate costs out to when you compare the two forms of mowers because the lifespan of lithium-ion batteries and the trouble of replacing them is necessary at different intervals compared to the cost of yearly routine maintenance for a gasoline engine.

The lithium-ion batteries electric mowers use are usually warrantied for three years, but realistically under normal use when charged and stored properly can last about 5 years. They might last even longer, but also for the sake of not over-estimating their lifespan or looking like electric mower evangelists, well say its reasonable to displace the battery by the 5-year mark to obtain another 5 years useful from your electric mower.

Knowing that, lets breakdown the costs predicated on our average quarter-acre lawn and the presumption that the lawn will undoubtedly be mown at least one time weekly from May to October of every year. Fuel costs are calculated using June 2022 charges for gasoline and electricity.

Gasoline Mower Electric Mower
Fuel Cost $152 $4
Engine Maintenance $150 N/A
Battery Replacement N/A $200
Projected 10-Year Cost $302 $204

Whats interesting is that, the more you mow, the higher the savings are. Realistically, a high-quality lithium-ion battery is wonderful for a large number of charge cycles. In the event that you double the amount of times you mow our quarter-acre lawn from once weekly to twice weekly for that entire ten-year span, you still spend significantly less than $10 on fueling the mower.

Do exactly the same with the gas mower and youll find yourself spending just a little over $300 at current prices (but still spend hundreds even though gas prices were to drop consistently on the next decade).

And when you grimace at the idea of paying $200 for reduced high-capacity battery, keep this at heart. For the essential electric push mowers, the price of the battery is practically the complete cost of the mower itselfso as it pertains time and energy to replace the battery, if you would like or require a totally new mower, it is possible to spend $250 rather than $200, or thereabouts, and obtain a fresh battery and mower all in a single.

Electric mowers of most kinds are increasingly competitive and for folks with small lawns, its really tough to overstate the savings. It is possible to charge a power push mower over 100 times for exactly the same money youd devote to a gallon of gas. So while its still not just a viable option for those who have huge rolling greens around their homes, the thousands of people with smaller mow-with-one-charge lawns should certainly take notice.
