Ever spent a Saturday morning hunched over a balky mower, coffee in hand, cursing the cold pull-start? Meet the PowerSmart HB8622S: a $399 self-propelled gas mower that promises to make suburban lawn chores less of a struggle. Picture this: you’ve just moved into a new house with a quarter-acre yard, armed only with a tight budget and a dream of a picture-perfect lawn. Does this budget mower live up to the hype in 2026 gas lawn mower reviews? We grabbed our lawn (and wallet) to find out. The HB8622S has a 21″ (actually 20.5″) cutting deck, a 140cc Briggs & Stratton 500e engine, and rear-wheel drive – specs that immediately catch the eye of any homeowner googling “best self-propelled gas lawn mower under $400.” This review is your story-driven guide through engine grunt, wheel-traction, mowing modes and more. Spoiler: It’s surprisingly capable for the price, but it comes with trade-offs. Ready? Let’s mow.

Engine Performance – Budget Power Under the Hood
Under the bonnet is a 140cc Briggs & Stratton E500 Series engine. Don’t expect the raw torque of a professional mower, but this OHV engine delivers steady cuts. PowerSmart’s marketing boasts a “powerful 140cc engine [that] delivers consistent performance and long-lasting durability” – and in our runs it was mostly true. It roared to life with a reliable pull-start (some reviewers note the recoil system is easy to engage), and it tackled tall grass better than we expected for the price. (By comparison, higher-end 21″ mowers often use 160–190cc engines.) One online tester praises a similar Briggs&Stratton-powered Troy-Bilt TB110 for its “quality cut” and “we expect [the engine] to last for a decade or more” – a helpful reminder that brand matters. In short, while PowerSmart’s 140cc won’t out-muscle a premium Honda or Toro, it provides about 5–6 horsepower of cutting grunt at a fraction of the cost. The throttle is single-speed (no cruise control), so you walk at your own pace. Overall, the engine’s reliability at this price point is respectable – just be prepared to use the choke/primer on a cold start and to maintain it yourself. (Ready to see the specs or buy?

Rear-Wheel Drive Traction – Climbing Slopes with Ease
This mower is self-propelled via rear-wheel drive (RWD), meaning the big 8″ back wheels do the pushing for you. In practice, that single-speed RWD makes hill-climbing pretty painless. PowerSmart notes the RWD system “provides improved traction and performance on incline slopes and uneven terrain”. Indeed, on a yard sloped just a few degrees our HB8622S ascended smoothly without jerking or bogging down. Imagine mowing up a gentle hill at weekend pace – the mower essentially shuttles you forward. It won’t auto-adjust like some high-end models (The Spruce’s favorites often have personal-pace or variable-speed drives), but the solid RWD system here still beats a manual push on hills. And those 8″ rear wheels plus 7″ fronts roll smoothly over bumps, so you can mow over uneven terrain without digging in. (By contrast, compact battery mowers like the Greenworks MO60L419 rely on user muscle – the PowerSmart spares you some sweat.) If your lawn has even modest slopes, you’ll appreciate not walking it uphill. (Quick tip: after a few passes you’ll learn the best walking pace to match the wheel drive, making mowing feel almost effortless.) For specs and to compare with others, see this product link.

Mowing Modes – Bag, Mulch, or Kick It Aside
The HB8622S is a 3-in-1 mower: you can mulch, bag, or side-discharge clippings without changing blades. A heavy-duty steel deck and blade are designed to finely cut clippings, supporting the mulching option. With the mulch plug installed, clippings are chopped “finely with little or no clumping” (as one Spruce reviewer observed of similar mowers) and left to nourish your lawn. Want a tidy yard? Clip in the 1.4-bushel catcher and wheel-fill the bag for a polished look. Need speed? Flip on side-discharge and blast clippings out the chute – it spits grass fast, though be careful: as one lawn-care guide warns, side-discharge will fling not just grass but any debris (rocks, sticks) away from the mower. So wear safety glasses when side-discharging. Height is easy to adjust via a single lever (6 positions from 1.5″ up to 3.9″), letting you adapt to season or lawn type. The takeaway: you get flexibility. Whether you choose to bag for curbside disposal or recycle as mulch, the PowerSmart handles both. Pro tip: frequent mulching will actually feed nutrients back into your lawn, but if time is tight you’ll probably appreciate having the catcher. Overall, the mowing modes are standard for this class – not groundbreaking, but they do cover all bases you’d expect.

Brand Comparisons – Where PowerSmart Fits in the Lineup
Shopping for a mower? You’ve heard the names. In quality terms, Honda set the gold standard for 140cc mowers (even now, one user on Reddit insists “if you go gas self-propelled, Hondas are legit”). Toro’s Recycler series and MTD’s Troy-Bilt also dominate higher price brackets. For example, tech reviewers rave about the Troy-Bilt TB110 21″ mower: “trusty and affordable,” with a “well-respected Briggs & Stratton engine”. In the current landscape, the PowerSmart falls below those name brands on the totem pole: it competes more with other budget machines (think big-box or import brands) than with Honda/Toro/Craftsman. On the battery side, a top pick like the Greenworks MO60L419 (a 56V cordless mower) gets high marks for small lawns, but costs more and has limited runtime. The PowerSmart trades the plug hassle for gas refuels. In short, PowerSmart is a value-priced contender: you sacrifice a bit of polish for a lower price. If you must pick “the best self-propelled gas lawn mower under $400,” it’s arguably on the short list, but know that you’re below the tier of premium U.S.-branded mowers. It’s like choosing a rugged off-brand pickup: it may not be a Ford or Chevy, but it gets the job done.

Storage – Folds Away for the Off-Season
Space-savers rejoice: this mower folds down nicely. The handle collapses with a quick lever, shrinking the height by about 70%. In practice, that means vertical storage is a breeze – it can lean almost upright in a shed or garage. We appreciate that the HB8622S ships mostly assembled: just unfold the handle and you’re mowing. The Spruce also loved a mower whose “sturdy handle folds down for storage”, and here PowerSmart delivers on that point. After a season of use, our unit still folded smoothly (just be careful to release the lever fully). For tight garages or sheds, this is a comfort: it’s no fun wrestling a bulky lawnmower in and out. (Storage tip: before winter, clean off grass, drain the tank if you’ll store it long-term, and fold it up to clear the floor.)

Common Issues – What to Watch Out For
No product is perfect, and neither is this one. One recurring complaint: handle durability. Several owners report the handle bar or its plastic mount is the weak point. On Reddit, one user’s handle broke after a few uses and the plastic mount literally pulled through. In fact, one builder said he had to reinforce the bolts with zip-ties and aftermarket parts to keep it from popping off. Moral of the story: inspect and tighten the handle bolts regularly, and don’t yank it by the handle alone. Another caution: a few owners mention engine leaks or smoking. One buyer used the mower only three times before it began belching smoke and oil, which is alarming if it happens to you (they ended up returning it). Most owners seem fine, but expect some of that “fresh-from-China” wear – check oil level and keep it topped up. Assembly can be fiddly too; plan on 10–15 minutes to unfold and check everything. Lastly, remember it’s a budget machine: if you’re upgrading from an heirloom Honda, you may find the experience a bit rougher. The engine is louder and has more vibration, and features are simpler (no variable speed, no battery indicator to worry about!). But don’t let that scare you: one owner salvaged a discarded PowerSmart, praised its fuel efficiency, and said “it runs great” for free. In our testing, aside from a flimsy handle, the mower ran reliably. With basic care (change the air filter, oil, tighten bolts), it will likely serve through the summer. If something does go wrong, the good news is replacement parts (filters, blades, etc.) are inexpensive and available in the PowerSmart parts store. (Remember: even top brands have hiccups – here you’re just on the budget side of those quirks.)

Warranty – What’s Covered (and What’s Not)
PowerSmart backs the HB8622S with a 2-year limited warranty for home use (90 days for commercial users). The fine print says they will “repair or replace defective parts” under normal use. That’s fairly standard. Key catch: engine issues are excluded. In other words, if the Briggs & Stratton 140cc motor dies, it’s on you. Batteries and chargers (for cordless units) have only 1-year coverage, but that’s moot here. The warranty requires you to send in the whole mower with your original receipt, and it’s non-transferable. So keep your invoice safe. In practice, customer experience is mixed. Some reviewers have complained about poor support or delayed responses. We didn’t need a warranty claim, so can’t testify firsthand. Bottom line: check your local store’s return policy and know you’ll have at least two seasons of coverage for frame or drive issues. For anything engine-related, though, assume it’s up to you.

Final Verdict: A Smart Buy for Savvy Shoppers?
So, is the PowerSmart HB8622S the “best self-propelled gas lawn mower under $400”? For the right buyer, it’s close enough. Its 21″ deck and 140cc B&S engine give it real cutting power for small-to-medium yards, and the rear-wheel drive makes slopes manageable. We found its 3-in-1 versatility and fold-down design genuinely useful. It’s by no means a top-tier workhorse – think of it as the budget SUV of lawn mowers: not luxurious, but practical. If you’re a DIY lawn enthusiast keeping a clean yard on a shoestring budget, it won’t leave you stranded. However, if you prioritize rock-solid durability or post-sale support, you’ll notice the trade-offs (handle frame, customer service, etc.). Compared to a Troy-Bilt TB110 or Toro Recycler (both pricier in this size), it’s a gamble; but compared to buying a used clunker or renting a mower, it’s compelling.
In summary: Pros – strong motor for the price, smooth RWD, handy folding handle, and 3-in-1 mowing options. Cons – build quality issues (especially the handle) and minimal features (no variable speed, no premium comfort). Think of it as a Steak and Beans dinner rather than gourmet: it fills you up cheap.
