Key Features & Specifications

Okay, here’s the features section for the PowerSmart lawn mower, as you requested, written as if I’ve actually used it:

PowerSmart 80V MAX 21in. Cordless Push Lawn Mower Features

Gas-Like Power, Without the Gas

The first thing that grabbed my attention with the PowerSmart 80V MAX 21in. Cordless Push Lawn Mower (DB2821) was the promise of “gas-like” performance. Honestly, I was a bit skeptical at first. I’ve used cordless mowers before that petered out halfway through the lawn. But the 80V MAX battery system in this PowerSmart mower is a game-changer. It really does deliver that robust power you’d expect from a gas mower, without all the noise and fumes.

I tested it on some pretty thick St. Augustine grass that usually gives electric mowers a hard time, and the PowerSmart 80V MAX just chewed right through it. I didn’t experience any bogging down or loss of power, even when tackling some overgrown patches. It felt like I was using my old gas guzzler, but without the hassle of pulling a cord and mixing fuel.

3-in-1 Versatility: Mulch, Side Discharge, or Bag

I love a tool that can do multiple jobs, and the PowerSmart 80V MAX 21in. Cordless Push Lawn Mower doesn’t disappoint. The 3-in-1 functionality – mulching, side discharge, and rear bag discharge – makes it adaptable to any lawn care need. For my regular weekly mowing, I prefer mulching. It finely chops the clippings and returns them to the lawn as fertilizer. This not only saves me the hassle of bagging but also helps keep my lawn healthy and green.

When the grass gets a little too long or I’m dealing with heavier clippings, I switch to the side discharge. This keeps the mower from getting bogged down and spreads the clippings evenly. The rear bag is great for those times when I want a super clean look, especially when I’m mowing near flower beds or walkways. Switching between modes is quick and easy, requiring no tools, which is a huge plus in my book. I found that the bag filled evenly and was easy to detach and empty.

Simple and Hassle-Free Operation

One of the biggest selling points for me is how easy the PowerSmart 80V MAX 21in. Cordless Push Lawn Mower is to use. No more yanking on a starter cord until my arm feels like it’s going to fall off! A simple press-button start is all it takes to get this mower going. And because it’s cordless, there are no emissions and virtually no maintenance required. I just pop in the battery, press the button, and I’m ready to mow.

The lightweight design also makes it incredibly easy to maneuver around my yard. I have a few tight spots and obstacles, but the PowerSmart 80V MAX handles them with ease. It’s also a breeze to store in my garage, taking up much less space than my old gas mower. The whole experience is just so much more pleasant and convenient.

Built to Last

Durability is always a concern when investing in lawn equipment, and the PowerSmart 80V MAX 21in. Cordless Push Lawn Mower seems well-built. The all-steel deck feels solid and sturdy, giving me confidence that it can withstand years of use. More impressively, it’s equipped with a brushless motor. Brushless motors are known for their longevity and efficiency. This translates to less wear and tear and a longer lifespan for the mower overall.

I haven’t had the mower long enough to fully assess its long-term durability. However, the robust construction and brushless motor give me confidence that it will hold up well over time. Plus, the 3-year warranty and lifetime tech support definitely provide peace of mind.

Who Should Buy This

Okay, let’s talk about the PowerSmart 80V MAX 21in. Cordless Push Lawn Mower, and who exactly would benefit from having this green machine in their garage. After using it for a few months now, I’ve got a pretty good feel for who this mower is really built for.

First off, if you’re a suburban homeowner with a small to medium-sized yard, this mower is practically tailor-made for you. I’m talking about the kind of yard where you can knock out the mowing in 30-45 minutes. You’re probably tired of wrestling with gas cans, choking engines that won’t start, and the whole song and dance that comes with a traditional gas mower. The PowerSmart 80V MAX is a game-changer here. No more fumes, no more frustrating pull starts – just pop in the battery and you’re off. I remember my neighbor, Martha, always complaining about her old gas mower. She switched to this PowerSmart model last summer, and now she actually enjoys mowing (or at least, she complains about it less!). She loves the quiet operation, too, since she often mows early on weekends. The ease of use and convenience of this cordless mower truly sets it apart for homeowners like her.

Then there’s the environmentally conscious homeowner who’s trying to reduce their carbon footprint. I know several folks who are actively trying to cut down on their reliance on gas-powered equipment, and the PowerSmart 80V MAX is a fantastic way to do that. Not only is it battery-powered, but it’s also surprisingly powerful. Some electric mowers feel a little anemic, but this one has plenty of oomph thanks to its brushless motor. I’ve been really impressed by its ability to handle thicker patches of grass without bogging down. It gives you that peace of mind knowing you’re not contributing to air pollution while keeping your lawn looking pristine.

Finally, let’s not forget the senior citizen or anyone with mobility limitations who still wants to maintain their own yard. Pull-starting a gas mower can be physically demanding, and lugging around a heavy machine isn’t ideal either. The PowerSmart 80V MAX is lightweight and easy to maneuver, and the push-button start is a godsend. My uncle, who’s in his 70s, was struggling with his old mower. After switching to this PowerSmart, he tells me he feels much more confident and comfortable tackling his lawn. The adjustable handle height also makes a big difference in terms of ergonomics.

This mower excels in scenarios where quiet operation is important, like in densely populated neighborhoods or early morning mowing. Also, I’ve found it to be particularly handy for quickly touching up small areas.

Now, who might not benefit from this mower? If you have a sprawling estate with acres and acres of lawn, or really tough, overgrown terrain, a gas-powered mower might still be a better choice for sheer power and run time. But for the vast majority of homeowners, the PowerSmart 80V MAX 21in. Cordless Push Lawn Mower offers a fantastic balance of power, convenience, and environmental responsibility.

🔴 Cons of the PowerSmart DB2821 80V MAX Mower

❌ Battery Life Can Be Limited on Larger Lawns

• If you have a ½ acre or more , you may need to pause for recharging—especially after hitting thick patches or tall growth.

❌ Not Ideal for Tall or Wet Grass

• Struggled slightly with overgrown or damp grass , leading to clumping and inconsistent discharge—best suited for regular mowing schedules.

❌ Single Battery Included – No Spare for Continuous Use

• While the 6.0Ah battery works fine, having an extra would make larger jobs more efficient—especially in spring or fall.

❌ Charging Time Is Relatively Long

• Took around 75–90 minutes to fully charge—plan ahead if you’re doing back-to-back yard tasks.

❌ Mulching Performance Could Be Better

• The mulching blade did okay, but some grass didn’t get finely chopped—occasional clumps still appeared on sunny days.

❌ Blade Speed Drops When Battery Is Low

• As the battery drained, I noticed a slight drop in cutting efficiency—leading to a few second passes over thicker patches.

❌ No Self-Propelled Option (on basic model)

• Some versions are self-propelled, but the base DB2821 is push-only—can be tiring on hills or large areas.

❌ Plastic Components Feel Less Durable Over Time

• While lightweight, the build doesn’t feel as rugged as higher-end electric mowers—some users report wear after heavy use.

🧾 Final Thoughts
