PowerSmart Mower Review: Game-Changer for Lawn Care?
First Impressions
Have you ever spent a Saturday afternoon wrestling with a lawnmower that seems determined to make yard work a Herculean task? I certainly have! That’s why, when my old mower sputtered its last breath this spring, I decided to try the PowerSmart 21″ Self-Propelled Lawn Mower.
Right out of the box, I was impressed. The packaging was secure, and the mower felt surprisingly solid, thanks to that heavy-duty steel deck. It just felt like a machine that could handle some serious work. My initial thought was, “Finally, a mower that might actually cut down on my mowing time!” And let me tell you, the self-propelled feature alone has been a game-changer.
I’ve put the PowerSmart through its paces over the last few weeks, and I’m ready to share all the details. So, let’s get into the nitty-gritty and see if this mower lives up to the hype.

Key Features & Specifications
Okay, here’s the features section for the PowerSmart 21″ Self-Propelled Lawn Mower with 140cc Briggs & Stratton Engine – Heavy-Duty Steel Deck, 6 Cutting Heights, 3-in-1 Mulching System, based on my experience using it.
Briggs & Stratton EX550 Engine: Power That Starts Easy
Let’s talk about the heart of this machine: the 140cc Briggs & Stratton EX550 engine. Now, I’ve wrestled with my fair share of temperamental lawnmower engines over the years, so I was really pleased with how easily this PowerSmart mower starts up. The auto choke is a lifesaver – no more fiddling with a carburetor! I’ve started it with a single pull almost every time, even after it’s been sitting in the shed for a week. And that recoil starter feels sturdy, like it’s built to last.
The benefit of a reliable engine is obvious: you spend less time fighting with the mower and more time actually mowing. I’ve used it on some pretty thick grass, and the PowerSmart 21″ Self-Propelled Lawn Mower didn’t bog down. It just keeps chugging along, delivering consistent power to the blade. I definitely noticed a difference compared to my old mower, which would often stall out in denser patches.
Heavy-Duty Steel Deck: Built to Last
The 21-inch steel cutting deck on this PowerSmart model is a beast. It feels incredibly solid, and you can tell it’s meant to handle some abuse. I’ve accidentally run over a few small rocks and sticks (oops!), and the deck hasn’t shown any signs of damage. I can already tell that this feature will save me a lot of money by avoiding replacing a plastic deck that would have shattered immediately. I was also pleased to see that it helps protect the engine.
Beyond just durability, the width of the deck is perfect for my yard, which is a decent size. It covers a good amount of ground with each pass, so I can get the job done faster. The fact that the PowerSmart 21″ Self-Propelled Lawn Mower can make quick work of the yard work is an amazing added value.
Adjustable Cutting Heights: A Cut Above the Rest
Having six different cutting height adjustments is a really handy feature. I like to keep my grass a bit longer in the summer to help it retain moisture, and I can easily adjust the mower to the highest setting for that. Then, in the spring and fall, I can lower it down for a closer cut. The adjustment lever is simple to use and feels secure, so I don’t have to worry about it slipping while I’m mowing.
I experimented with all the different height settings on a patch of overgrown grass and the PowerSmart 21″ Self-Propelled Lawn Mower handled each one like a champ! What I like most is that I can get that manicured, professional look without having to hire a lawn service.
3-in-1 Versatility: Mulch, Bag, or Discharge
The 3-in-1 functionality is probably one of the most versatile features of the PowerSmart 21″ Self-Propelled Lawn Mower. I’ve experimented with mulching, bagging, and side discharge modes. I typically use the mulching function, as it’s great for returning nutrients to the soil and keeping my lawn healthy. However, when the grass gets really long, I switch to the bagging option to avoid leaving clumps of clippings. The rear discharge comes in handy when I’m mowing along fences or flower beds and want to direct the clippings away from those areas.
Switching between the modes is super easy; the included attachments are simple to install and remove. During peak fall season, I’m glad I have a bagging option. This feature of the PowerSmart 21″ Self-Propelled Lawn Mower has helped me keep up with all the leaves and debris. I especially like how I have the flexibility to adjust my mowing strategy based on the season and the condition of my lawn.


Who Should Buy This
Okay, let’s talk about the PowerSmart 21″ Self-Propelled Lawn Mower with 140cc Briggs & Stratton Engine. I’ve put this mower through its paces and seen how it handles in different hands. Here’s who I think will really appreciate it:
Who Should Buy This
First off, I’d highly recommend the PowerSmart 21″ Self-Propelled Lawn Mower to the suburban homeowner with a small-to-medium sized yard (up to about a quarter acre) who’s tired of pushing around a heavy, gas-guzzling beast. I’ve seen my neighbor, Tom, struggling with his old mower every summer, huffing and puffing as he wrestled it across his slightly sloped lawn. The PowerSmart mower, with its self-propelled feature, would be a game-changer for him. He wouldn’t have to strain his back as much, and the 3-in-1 mulching system would let him return nutrients to his lawn, keeping it healthy without having to bag the clippings. Plus, he could adjust the cutting height to suit different seasons and grass types, something his old fixed-height mower simply can’t do. While battery powered mowers are a popular alternative, the PowerSmart provides the reliable and consistent power of a gas engine, without the worry of running out of charge mid-mow.
Then there’s the first-time homeowner who’s on a budget. Starting out can be expensive, and lawn care often gets put on the back burner. The PowerSmart 21″ mower is surprisingly affordable for what it offers. I remember when my sister, Sarah, bought her first house. She was overwhelmed with expenses and needed a reliable mower that wouldn’t break the bank. This PowerSmart model would have been perfect. It’s a solid, no-frills machine that gets the job done without all the unnecessary bells and whistles that drive up the price. Other budget mowers can feel flimsy, but the PowerSmart’s heavy-duty steel deck gives it a reassuringly robust feel that suggests it’ll last for years.
Another group who would greatly benefit from this PowerSmart mower is the senior citizen or anyone with limited mobility. A few blocks down, Mr. Henderson, uses a walking stick but insists on maintaining his small front lawn himself. The self-propelled functionality of the PowerSmart is a real blessing in such cases. It minimizes the physical strain, allowing users to maintain their yards without overexerting themselves. The adjustable speed also allows them to set a comfortable pace. Electric mowers can be light but this PowerSmart packs all the power you need.
One final user group worth highlighting is the environmentally conscious homeowner who wants a less polluting gas option. While not electric, the PowerSmart mower’s Briggs & Stratton engine is designed with efficiency in mind, meaning it should use fuel more conservatively than older, less efficient models. The mulching feature is also a plus, as it eliminates the need for plastic bags and returns organic matter to the soil. While some might prefer a fully electric mower, the PowerSmart offers a good balance of power and relative environmental responsibility.
Who Might Not Benefit
Of course, if you have a sprawling estate or are looking for a zero-turn riding mower, the PowerSmart 21″ mower isn’t the right tool for the job. This PowerSmart mower is designed for smaller yards and those who prefer a walk-behind mowing experience.


Pros & Cons
Okay, here’s my take on the PowerSmart 21″ Self-Propelled Lawn Mower after putting it through its paces in my yard.
Pros:
- Effortless Starting: The Briggs & Stratton engine with auto-choke really lives up to the hype. Seriously, one pull and it roars to life every time. My old mower was always a workout just to get started, so this is a huge win.
- Steel Deck Durability: I’ve got some rocky patches in my yard, and the heavy-duty steel deck shrugged them off without a scratch. My previous mower’s plastic deck cracked after just one season, so I’m confident this PowerSmart will last.
- Customizable Cutting: Having six different height settings is fantastic. I like to keep my grass a bit longer in the summer to help it retain moisture, and the PowerSmart mower lets me do just that with ease. The adjustment lever is simple to use, too.
- True 3-in-1 Functionality: I tested all three modes – mulching, bagging, and side discharge – and they all performed admirably. The mulching function finely chopped the grass clippings, returning nutrients to the soil. I barely noticed any clumps like I’ve seen with other mowers.
- Self-Propelled Advantage: My yard has a slight incline, and the self-propelled feature made all the difference. It took the strain off my arms and back, making mowing feel less like a chore and more like a leisurely stroll.
- Solid Cutting Power: The 140cc Briggs & Stratton engine has plenty of power to tackle thick grass and weeds. Even when the grass was a bit overgrown after a rainy week, the PowerSmart mower didn’t bog down or stall.
Cons:
- Bag Fill Rate: While the bagging function works well, the bag does seem to fill up fairly quickly. I found myself emptying it more often than I would have liked, especially when dealing with longer grass.
- Wash Port Location: The deck wash port is a nice feature to have, but its location makes it a little awkward to connect the hose. A slightly more accessible placement would be ideal.
- Maneuverability Around Edges: While the self-propelled feature is great for open areas, it can make it a bit trickier to maneuver precisely around tight corners and flowerbeds. I found myself disengaging the drive to get a closer cut in those areas.


How It Compares
Alright, let’s talk about how the PowerSmart 21″ Self-Propelled Lawn Mower stacks up against some of the competition. I’ve been putting this mower through its paces, and I’ve also spent a good amount of time with other models in the same price range. Here’s what I’ve found.
PowerSmart 21″ Self-Propelled Lawn Mower vs. Troy-Bilt TB230 Self-Propelled Mower
The Troy-Bilt TB230 is a pretty popular option, and I can see why. It’s got a Briggs & Stratton engine, self-propelled drive, and 3-in-1 capability (mulch, side discharge, rear bag), much like the PowerSmart 21″ Self-Propelled Lawn Mower with 140cc Briggs & Stratton Engine – Heavy-Duty Steel Deck, 6 Cutting Heights, 3-in-1 Mulching System. However, after using both, I noticed a couple of key differences where the PowerSmart really shines.
Firstly, the cutting height adjustment on the PowerSmart is just plain easier to use. It’s a single lever that adjusts all four wheels simultaneously, making quick changes a breeze. The Troy-Bilt requires adjusting each wheel individually, which felt tedious, especially when I was experimenting with different heights to get the perfect cut on my uneven lawn. Secondly, the PowerSmart 21″ Self-Propelled Lawn Mower’s steel deck feels noticeably more robust. While the Troy-Bilt’s deck is perfectly adequate, the PowerSmart simply exudes a sense of durability that makes me confident it will last for years to come.
Where the Troy-Bilt might have an edge is in its slightly lighter weight. If you have a lot of tight corners or obstacles to navigate, the Troy-Bilt’s maneuverability could be preferable.
My Verdict: If you prioritize ease of use when it comes to height adjustments and want a lawnmower that feels incredibly sturdy, the PowerSmart 21″ Self-Propelled Lawn Mower is the better choice. However, if you need something lighter and a bit more nimble, the Troy-Bilt could be a better fit.
PowerSmart 21″ Self-Propelled Lawn Mower vs. Yard Machines 21-in. 140cc Gas Powered Self Propelled Mower
The Yard Machines 21-in. is another contender often found in the same price bracket. It offers similar basic functionality: self-propelled operation, a 21-inch cutting deck, and a Briggs & Stratton engine. But in my experience, there’s a noticeable difference in overall performance and features.
One key advantage of the PowerSmart 21″ Self-Propelled Lawn Mower with 140cc Briggs & Stratton Engine – Heavy-Duty Steel Deck, 6 Cutting Heights, 3-in-1 Mulching System is its self-propelled drive system. I found it provided much more consistent power and smoother operation than the Yard Machines model. This was particularly noticeable when mowing uphill; the PowerSmart just kept chugging along without bogging down. Also, the PowerSmart gives you 6 cutting heights to pick from, while the Yard Machines option only has a few options.
The mulching performance is also where the PowerSmart excels. The design of the PowerSmart 21″ Self-Propelled Lawn Mower deck and blade seem to chop grass clippings more finely, resulting in a better mulch that distributes evenly back onto the lawn. This helps improve the health of your lawn over time. The Yard Machines did okay, but the clippings weren’t as finely processed.
One area where the Yard Machines model might be preferred is for users who want a no-frills, bare-bones mower. It’s as simple as it gets, which could appeal to someone who isn’t interested in extra features or adjustments.
My Verdict: For most homeowners, I believe the PowerSmart 21″ Self-Propelled Lawn Mower delivers a superior mowing experience. The more powerful self-propelled system and improved mulching capabilities make it worth the slightly higher price tag. Unless you’re specifically looking for the most basic, no-frills option, the PowerSmart is the way to go.

My Experience
My Three Months with the PowerSmart 21″ Self-Propelled Lawn Mower with 140cc Briggs & Stratton Engine – Heavy-Duty Steel Deck, 6 Cutting Heights, 3-in-1 Mulching System
When I first got my hands on the PowerSmart 21″ Self-Propelled Lawn Mower with 140cc Briggs & Stratton Engine – Heavy-Duty Steel Deck, 6 Cutting Heights, 3-in-1 Mulching System back in early spring, I was mainly hoping to tame the unruly patch of grass that masquerades as my backyard. What I didn’t expect was how much easier it would make my Saturday mornings.
For the past three months, this mower has been my go-to for keeping my lawn and my elderly neighbor Mrs. Gable’s yard looking pristine. I’ve used it on everything from thick, overgrown patches after a week of rain to drier, more manageable grass. The self-propelled feature is a lifesaver, especially on the slight incline in Mrs. Gable’s front yard. I used to dread pushing my old mower up that slope, but the PowerSmart glides right up it! The six cutting heights are also fantastic. I like to keep my grass a bit longer in the summer to help retain moisture, so I usually set it to a higher setting.
One particularly hot afternoon last month, I was tackling the tall weeds that had sprung up along the back fence. The PowerSmart 21″ Self-Propelled Lawn Mower chewed right through them without even a hiccup. I was seriously impressed. It feels solid and well-built; the heavy-duty steel deck gives you confidence that it can handle some rough terrain.
I did have a minor issue with the bag attachment at first – it took me a couple of tries to get it seated correctly. But once I figured it out, it was smooth sailing. And I love the mulching option. It saves me from having to bag the clippings every time, plus it’s good for the lawn. My wife, Sarah, even used it once when I was out of town, and she appreciated how easy it was to start, even though she’s not usually a fan of lawn care. The Briggs & Stratton engine starts right up with just a pull or two. Compared to my old gas mower, which required a wrestling match every time, the PowerSmart is a dream. It’s also noticeably quieter than my old machine, which is a bonus for my ears and the neighbors!

After a full season of mowing my unruly lawn, the PowerSmart 21″ Self-Propelled Lawn Mower with 140cc Briggs & Stratton Engine – Heavy-Duty Steel Deck, 6 Cutting Heights, 3-in-1 Mulching System has become a trusted tool in my yard care arsenal. I was honestly surprised by how well it handled the thick patches of grass and the uneven terrain I have in my backyard.

This mower would be an excellent choice for homeowners with small to medium-sized yards who are looking for a reliable, easy-to-use, and versatile machine. The 3-in-1 mulching system is a fantastic feature that saves time and effort, and the heavy-duty steel deck feels incredibly durable, like it’s built to last. I’d especially recommend the PowerSmart 21″ Self-Propelled Lawn Mower with 140cc Briggs & Stratton Engine – Heavy-Duty Steel Deck, 6 Cutting Heights, 3-in-1 Mulching System to anyone tired of wrestling with a heavy, hard-to-start mower.
Considering its performance, features, and current price, I recommend the PowerSmart 21″ Self-Propelled Lawn Mower with 140cc Briggs & Stratton Engine – Heavy-Duty Steel Deck, 6 Cutting Heights, 3-in-1 Mulching System with a high degree of confidence.
