Cordless Power, Unleashed: Greenworks Commercial 82V H.O.G. Chainsaw

Greenworks Commercial Pushes Battery-Powered Chainsaws into New Levels of Performance

A few years ago, at Equip Expo (formerly GIE), we got a pleasant surprise—three different brands announced 20-inch battery-powered chainsaws at the same time. This time around, only one is pushing that benchmark further, and the Greenworks Commercial 82V H.O.G. (Hogsaw) chainsaw is poised to redefine what battery power is capable of in the chainsaw sector.

We’re taking a closer look at one of the most powerful battery-powered chainsaws on the market to see what it has to offer the Pros. Will this saw make the cut? I want to find out.

Pros

Excellent cutting power
Multiple bar length options
Familiar form factor
Well-balanced design

Cons

A little expensive

Greenworks Commercial 82V H.O.G. Chainsaw Performance

The major talking points about this chainsaw center on its performance. Relying on a 7.2Ah battery for power, the brushless motor can produce 5.0 kW of raw power output, which is very impressive. The entry-level bar is 20 inches, but this is the first battery-powered chainsaw rated to handle 24 or 28-inch bars.

Obviously, that offers more cutting capacity than before. But to really put it into context, we need to take a closer look at that power number. Greenworks Commercial already had the strongest 20-inch saw, though models from Stihl and DeWalt were in the ballpark.

That saw produces 3.4 kW of power, so the 5.0 kW of the H.O.G. chainsaw represents a 47.1% increase in power! But how that power translates into real-world performance is something we’ll dive into a little bit later. First, I want to take you through some of the key features that set this saw apart from the pack.

Greenworks Commercial 82V H.O.G. Chainsaw Design Notes

Size and Weight

As chainsaws go, Greenworks didn’t stray too far from the norm in terms of the overall look and feel. The OCS800 weighs 18.25 pounds as a bare tool, 24.2 pounds with the recommended 7.2Ah battery, and measures 46 inches from tip to tail with a 24-inch bar.

Bar and Chain

Looking down at the business end, Greenworks again opted to use an Oregon bar and chain, which I think was the smart play. The benefit of this choice is that finding replacements is easy.

The kitted 84-tooth chain features a full-chisel cutting tooth and a large depth gauge that helps reduce kickback. The curved depth guide also sports an etched sharpening guide so you can effortlessly keep an effective edge on your chain. On the surface, this sounds great, but this configuration does present one small problem—lower cutting speed.

The Oregon Vanguard 72V084X chain is a solid choice for homeowners and light felling work, but the cutting speed is slower than many of the more aggressive Pro-grade chains. The trade-off here is that this chain puts less strain on the motor, meaning you get more runtime and a longer service life from the saw. I think that’s a pretty fair exchange when it comes to battery-powered OPE.

It’s worth noting that you can always swap out the stock chain for a more aggressive one, but you will sacrifice some runtime.

Grip and Trigger

Greenworks kept the grip and trigger design pretty simple. You have a traditional beavertail safety with a two-finger trigger, along with a power button on the side that activates the saw. You also get a rugged metal top handle and an electronic chain brake for improved safety.

Large Metal Bucking Spikes: Helps the saw stay engaged while bucking logs
Captured Bar Nuts: Prevents you from misplacing or losing your bar nuts in the field

Hands-On Testing With The Greenworks Commercial H.O.G.

Putting this saw to the test was a little tricky, since we don’t have regular access to large-diameter logs. However, in this case, fortune smiled upon us in the form of an Oak tree that had recently been felled at Tom’s church! The trunk was roughly 28 to 30 inches wide, so this is a true test of the saw’s maximum cutting potential.

The OCS800 started off strong, chewing through the log, maintaining RPMs, and spewing wood chips out the back. As I mentioned earlier, the stock chain produces slightly smaller wood chips than what we’re used to seeing from Pro-grade saws, but still, this saw managed the cuts.

The only issue during this test was the runtime. We only managed to get four full cuts of this large-diameter tree before the CORE530 7.2 Ah battery gave out. On the surface, this doesn’t paint Greenworks in a positive light, but it’s important to remember that we were burying the entire bar. This is a big ask for any saw and slightly unrealistic for everyday use, so we wanted to shake it up and move to a task that’s a little more reasonable.

On this go-around, we set up a 12-inch oak log and began to make a series of cuts. Unsurprisingly, the Optimus Hogsaw tore through the log with ease, leaving a clean cut in its wake. The bucking spike held firm on the bark and allowed me to apply additional pressure during the cut.

The performance level is nothing short of impressive. Admittedly, the cutting speed is a little lower than what I expected, but the 80cc equivalent power allowed this saw to maintain RPMs, even during the most intense cuts.

All four options come with Greenworks’ new CORE530 7.2 Ah battery, a dual-port charger, and are backed by a 2-year warranty.

Should You Buy It?

The Greenworks Commercial 82V H.O.G. chainsaw is a clear statement piece for what battery-powered saws are capable of right now.

With a massive 5.0 kW power output and the ability to run bars up to 28 inches, this saw pushes well into territory that was once reserved strictly for gas. In real-world testing, that power shows up where it matters—strong torque, steady RPMs under load, and the ability to handle large-diameter cuts without backing down.

There are some trade-offs. The stock chain favors runtime and longevity over outright cutting speed, and when you’re pushing the saw to its limits with full-bar cuts, runtime takes a noticeable hit. But those compromises feel intentional rather than limiting, especially considering the overall performance.

At the end of the day, this isn’t just a capable battery chainsaw—it’s a serious professional tool that challenges what we expect from cordless equipment. If you’re willing to manage battery strategy and possibly fine-tune your chain setup, the H.O.G. delivers impressive cutting power in a package that brings battery technology closer than ever to true gas replacement.
