Professional Tool Reviews for Pros


Professional Lawn Care: Making the Switch to Battery Power


Changing Professional Lawn Care Crews to Battery Power Takes More Than Just Different Equipment

As new regulations and customer interest continue to help battery-powered lawn mowers and other lawn care equipment gain traction, we decided to take a look at what it takes for a professional lawn care crew to kick the (gas) can. “Professional lawn care” can mean several things. For the purposes of this case study, we’re sticking with residential lawn care and a little consideration for facilities and campuses that use traditional equipment.

Battery vs Gas Lawn Care Equipment

When we first started reviewing battery-powered OPE, there was a clear difference between the power you could expect compared to gas engines. That gap has largely been erased.

Entry-level products are still low on power for sure. However, trimmers and edgers often have 25cc gas equivalent power and Makita even has models that hit 30cc gas power.

Chainsaws are another success story. It’s now common to find 30cc+ and 40cc+ power equivalents.

There are legitimate commercial-level battery-powered lawn mowers available and several high-profile lithium-ion zero-turn mowers as well.

Even blowers are jumping the gap. We’ve tested models that can hit a little more than 20 Newtons of blowing force—the same as entry-level commercial backpack blowers.

Of course, high-end gas equipment still greatly exceeds what battery power currently offers. And it’s a heck of a lot faster to refill a gas tank than it is to wait for batteries to recharge. We’ll go down that road in a moment.

Trailer Load Out

Take a look at your typical residential lawn care crew’s trailer. You can replace every piece of equipment with a battery-powered option.

Equipment Loadout Options

  • Zero Turn Mower
  • Walk-Behind Mower
  • String Trimmer
  • Edger
  • Brush Cutter
  • Hedge Trimmer
  • Chainsaw
  • Pole Saw
  • Backpack Blower

Heck, you can even get a fully electric truck to tow the trailer with now.

How Many Batteries Get You Through a Day

The big question is how many batteries do you need to get through the day? See, the issue of using battery power isn’t one of recharging throughout the day, it’s leaving with enough packs so you don’t have to recharge until you get back to the shop.

It’s primarily a question of trigger time. How many minutes or hours of actual use does each tool get? To get started on that, we need to make a few assumptions. Just know that your actual needs will vary based on the customers you serve and the sizes of their properties. Here’s what we’re going with:

  • 1/4-acre lot sizes
  • 2-man crew
  • 20 lawns per day
  • Cut, trim, edge, and blow
  • Lithium-ion ZT mower
  • Makita 18V X2 products
  • String trimmer: 30 active minutes per charge
  • Edger: 20 active minutes per charge
  • Blower: 20 active minutes per charge
Active Timex 20 LawnsBatteries
ZT Mower20 min6 hrs, 40 minInternal
String Trimmer10 min3hrs, 20 min14 batteries
Edger5 min1 hr, 40 min10 batteries
Blower5 min1 hr, 40 min10 batteries

Looking at this scenario, you’d need 34 batteries. For the sake of the argument, let’s assume an even 40 to make sure you have spares if your day runs long or you run into unexpected additional work on one or more of your properties.

Behavior Change Requirements

Relearning Equipment Use

In our area of Central Florida, lawn crews tend to be a little…aggressive. We see them take string trimmer guards off and run 24 inches of line, and they like to run everything at full power.

If you can train your crew to use only the power the tool needs, it can drastically change things. For example, the string trimmer in our scenario above is Makita’s XRU18. We like it because it can run up to a 0.105-inch line and has 30cc gas power. Running at full speed with a 0.080-inch line, it only gets about 16 minutes of runtime. But managing the power as we come across varying grass species and densities, we’re able to get 30 minutes on a charge consistently, and often more.

Makita XRU18

The same goes for blowers. Our Makita XBU02 runs for about 12 minutes at wide-open throttle (WOT). But if you’re just blowing grass off of hard surfaces, adjusting the power level makes it pretty easy to get 20 minutes out of it.

By making those adjustments, you do spend a little more time on site. We’re talking no more than 5 minutes total on the size properties we’re dealing with and still getting it done in a 30-minute window.

The Upside

There’s an upside to this as well—no stops at the gas station. How much time do you spend each morning filling up cans and waiting for your helper to finish hitting the restroom, grabbing breakfast, and chatting with the attendant?

Makita tells us that some crews they’ve worked with can lose up to an hour every single morning! That more than makes up for the extra time you’re spending managing battery power and may even leave enough time to take on another lawn per day. You spend less money paying your guys when they’re not working and may even increase your profit margin.


Cost of Switching to Battery Power

There’s no doubt the initial cost of switching to battery-powered lawn care equipment can be intimidating. Let’s break it down and see what we’re dealing with. The gas and battery options we’re choosing are all professional-level.

Mid-Level GasPremium GasBattery
Zero Turn$7,999$14,999$13,799
Walk-Behind$799$1,299$999*
String Trimmer$289$419$469*
Edger$299$419$199
Brush Cutter$349$469$579*
Hedge Trimmer$399$579$389*
Chainsaw$299$749$409*
Pole Saw$479$629$699*
Blower$249$599$329*
Batteries (20)NANA$2,000
Total$11,161$20,161$19,871
* Purchased as a kit with batteries and charger. Gas price ranges based on products from Makita, Echo, Husqvarna, and Stihl.

Out of the gate, getting started with a full battery-powered loadout is a similar price to starting with premium gas products. Notice that by buying kits with batteries and chargers, you reduce the number of additional batteries you need to buy.

Got Gas?

What you don’t see (yet) is how the cost of gas comes into play. Conservatively, that’s about 20 gallons per day in our scenario. Here’s how it breaks down over time compared to batteries that are on a 3-year replacement cycle:

1 Day1 Month1 Year5 Years
Gas Consumption20 gal417 gal5,000 gal25,000 gal
New Batteries00040
Based on 3-year battery replacement cycle and 250 mowing days per year

Gas Cost$40$834$10,000$50,000
Battery Cost$0$0$0$4,000
Based on gas at $2.00/gallon and $100/battery
Equipment + Fuel1 Day1 Month1 Year5 Years
Mid-Level Gas$11,201$11,995$21,161$61,161
Premium Gas$20,201$20,995$30,161$70,161
Battery$19,871$19,871$19,871$23,871
Initial cost of equipment plus fuel/batteries

Our final cost estimates don’t include replacement batteries for your zero-turn because we frankly don’t know how much to expect. Even if you assume a $6,000 replacement cost, you’re still well under the 5-year fuel cost estimates.

This also doesn’t take into consideration maintenance and repair costs, which may be significant over a 5-year ownership cycle, or the potential increase in the cost of fuel and batteries.

Benefits of Battery-Powered Lawn Care Equipment

There are some obvious advantages that come with battery-powered lawn care equipment: low noise, no emissions, and far less maintenance. Your crew is more productive and our case study also shows that the cost of ownership is also less over time.

There’s another major advantage as well—higher-paying clients. Depending on what part of the country you live in, local ordinances or HOA guidelines can prevent you from using gas lawn equipment. For some clients, they may just prefer that you take care of their lawns with less noise and emissions.

Regardless, that’s a premium service they won’t get from a traditional gas-powered lawn care business. Meeting those extra demands can and should come with a higher price tag. Not only does your cost of ownership drop, but your profitability goes up. Whether your goal is to expand your business or ensure you have the time and money for that 2-week vacation to Portugal, battery power has the potential to help you get there.

You can also charge in a vehicle with an inverter or 12v charger. You can also build a power bank to run chargers from and it can be solar powered and plug in.

So the electricity to charge those 20 batteries 250 days over 5 years is somehow free. Also a human being has to spend the time at a charging station for those 20 batteries and change them out each evening until all 20 are fully charged. I doubt there will be 10 double chargers in real world setup. Perhaps put a kilowatt meter on a double charger and add that cost in. I’ll bet the farm that all these battery powered lawn tools may not last as long as you think. Will replacement parts be available over those 5 years of… Read more »

they need 25-30inch for the commercial guy

I would have ran this model with either Greenworks Commercial or EGO with the backpack power stations and have the tools run off the backpack cable.

34 batteries to swap out in a day – has anyone tried this?

I have scientific proof that batteries always run out when you’re furthest from the spare pack.
It’s science!

Seems to me this is going to cause a lot of unnecessary pauses and interruptions.

The larger voltage / larger amp-hour tools with power packs might be able to close the gap on ‘work flow’ with gas moreso than Makita.
