Best Rear Bagging Lawn Mower Review
PowerSmart 21-Inch Gas Lawn Mower – Best Overall
This workhorse of a mower delivers professional-grade cutting power and effortless self-propulsion, making it a top contender for homeowners with medium to large yards. Powered by a 140cc Briggs & Stratton engine, it fires up smoothly and maintains consistent RPMs even in thick grass, eliminating frustrating stalls. The 21-inch steel deck slices through overgrown lawns with authority, while the 3-in-1 system—bagging, mulching, or rear discharge—gives you full control over grass clipping management, a feature that truly elevates its versatility.
In real-world testing, the mower excels on uneven terrain and mild slopes, thanks to its rear-wheel drive and 10-inch rear tires that grip reliably without slipping. The single-lever height adjustment (1.5″ to 3.9″) makes switching between settings a breeze, and the 1.4-bushel rear bag fills evenly without constant clogging—though damp grass can slow bagging efficiency slightly. While it handles most conditions with confidence, the lack of variable speed on the self-propel system means you’re locked into one pace, which can feel too fast in tight spaces or too slow on open turf.
Compared to the PowerSmart 22-inch model, this one trades a bit of deck width for a more refined engine pedigree and smoother operation. It’s not as aggressive on raw coverage, but the B&S engine’s reputation for durability gives it an edge in long-term reliability. Ideal for homeowners who value consistency, ease of use, and trusted engine performance, this mower strikes a smart balance between power and practicality. It delivers better engine refinement and traction than the AMERISUN, though with slightly less raw power than the 170cc competition.
- B&S engine reliability
- 21-inch steel deck
- 3-in-1 mowing modes
- Self-propelled RWD
- Single-lever height adjust
- No variable speed
- Smaller deck vs 22-inch
- Bag struggles in wet grass
PowerSmart 22-Inch Self Propelled Mower – Best Self-Propelled
Meet the muscle-packed performer built for larger lawns and demanding mowing schedules—this 22-inch beast from PowerSmart doesn’t just cut grass, it conquers it. The 170cc OHV engine delivers serious torque, effortlessly powering through tall or wet grass where lesser mowers bog down. With a wide 22-inch cutting deck, it covers more ground per pass, slashing mowing time significantly—ideal for yards up to half an acre. The 3-in-1 functionality (mulch, side discharge, rear bag) adds serious flexibility, and the 1.4-bushel bag is simple to remove and empty, minimizing mess and downtime.
During testing, the mower proved exceptionally efficient on flat, open lawns, where its single-speed self-propel (3.5–4.1 km/h) kept pace well with brisk walking. The rear-wheel drive provides solid traction, though it can struggle slightly on steep inclines when the bag is full. The fine-cutting blade produces small, even clippings, enhancing mulching performance and reducing clumping. However, the fixed speed limits precision in tight corners or around landscaping, and the foldable design, while space-saving, feels slightly less rigid than non-folding frames during aggressive mowing.
When stacked against the B&S-powered 21-inch model, this mower wins on raw cutting width and engine power, making it the better pick for larger, open yards where speed matters most. It’s not as nimble in tight spaces, but for sheer productivity, it’s unmatched in this lineup. Compared to the AMERISUN, it offers superior engine output and wider coverage, though at the cost of a less refined height adjustment system. If you’re after maximum efficiency and don’t mind a fixed pace, this is the most powerful bagging-focused mower here.
- 170cc OHV engine
- 22-inch cutting width
- 3-in-1 mowing options
- Foldable for storage
- Large rear wheels
- Fixed self-propel speed
- Less agile in tight spaces
- Slight frame flex when folded
AMERISUN 21″ Gas Lawn Mower – Best Mid Range
The AMERISUN 21-inch mower is a surprisingly capable mid-tier performer that blends strong engine specs with thoughtful design, making it a standout for value-focused buyers. Its 144cc OHV 4-stroke engine with auto choke starts reliably with minimal pull effort—no priming or choke adjustments needed—ideal for users who hate finicky engines. The 21-inch steel deck delivers clean, even cuts, and the 3-in-1 system (mulch, side discharge, bag) ensures you can adapt to any lawn condition. The dual ball-bearing 10-inch rear wheels make it remarkably easy to push, even on bumpy or sloped lawns, reducing fatigue significantly.
In real-world use, this mower shines in medium-sized yards with mixed terrain, where its oversized wheels and smooth roll make navigation effortless. The single-lever height adjustment (1.5″ to 3.9″) is intuitive and consistent across all wheels, ensuring an even cut every time. The 1.4-bushel rear bag fills well, though like others, it can clog in damp conditions. While it lacks self-propulsion, the low-resistance deck and smooth wheels compensate, making it one of the easiest push mowers to maneuver in its class. It’s not built for half-acre lawns, but for yards under 1/3 acre, it’s impressively efficient.
Compared to the PowerSmart models, this one trades self-propel and slightly less engine power for a lower price point and excellent out-of-box usability. It’s not as fast as the 22-inch PowerSmart, nor as engine-refined as the B&S model, but it delivers 90% of the performance at a more accessible cost. Perfect for homeowners who want a reliable, low-maintenance gas mower without overspending, it’s the smart middle ground between budget builds and premium performers. It offers better wheel quality and easier start than the base PowerSmart, though without the self-propel advantage.
- Auto choke engine
- 144cc OHV power
- 3-in-1 mowing modes
- Dual ball-bearing wheels
- Tool-free setup
- No self-propulsion
- Push-only design
- Bag clogs in wet grass

When selecting a rear bagging lawn mower, focus on key features that ensure efficiency, ease of use, and durability. Here’s what to consider:
Engine Power & Reliability
A powerful engine ensures smooth operation, especially for thick or tall grass.
– Briggs & Stratton (B&S) engines (e.g., PowerSmart 21″) are known for durability.
– OHV (Overhead Valve) engines (e.g., AMERISUN 144cc) offer better fuel efficiency and longevity.
Why it matters: A strong engine handles tough mowing jobs without stalling.
Cutting Width & Deck Material
A wider cutting deck reduces mowing time.

Why it matters: Steel decks last longer, while wider decks speed up yard work.
Self-Propelled vs. Push Mowers
Self-propelled mowers (e.g., PowerSmart Self-Propelled) are ideal for slopes or large yards.
– Rear-wheel drive provides better traction on uneven terrain.
Why it matters: Less effort required, especially on hills.
Versatility (3-in-1 Functionality)
Look for bagging, mulching, and rear-discharge options (all models listed).
– 1.4-bushel bag capacity ensures fewer stops to empty clippings.
Why it matters: Adaptability for different lawn needs.
Adjustability & Storage
- Single-lever height adjustment (1.5″–3.9″) suits seasonal grass growth.
- Foldable handles (AMERISUN) save storage space.
Other Quick Considerations
- Wheel size: Larger rear wheels (10″) improve maneuverability.
- Weight: Lighter models are easier to push but may lack durability.
- Noise levels: Gas mowers are louder than electric alternatives.

Data-Driven Analysis: Evaluating Rear Bagging Lawn Mowers
Choosing the best rear bagging lawn mower requires moving beyond specifications and leveraging available data. We analyzed user reviews across multiple retail platforms (Amazon, Lowe’s, Home Depot) to quantify satisfaction with engine reliability – consistently highlighting Briggs & Stratton engines as a top performer. Comparative data on engine types, like OHV engines, demonstrates a correlation between this design and longer operational life, supported by warranty lengths offered by manufacturers.
Feature analysis focused on the practical impact of cutting width and bag capacity.

Review sentiment analysis confirmed the value of a 3-in-1 system (bagging, mulching, side discharge) for overall user satisfaction, specifically noting that a 1.4-bushel bag capacity minimizes interruption during mowing. This data-driven approach complements the functional considerations outlined in the Buying Guide, offering a more informed selection process.
FAQs
What makes a rear bagging lawn mower different?
A rear bagging lawn mower collects grass clippings in a bag attached to the rear of the mower, offering a clean finish and eliminating the need to rake. This is in contrast to side discharge or mulching mowers.
Are Briggs & Stratton engines really better?
Based on our analysis, Briggs & Stratton engines consistently receive high user ratings for reliability and durability, making them a preferred choice for many rear bagging lawn mowers.
What bag capacity should I look for in a rear bagging mower?
A 1.4-bushel bag capacity is a good balance, providing ample space for clippings without being overly heavy or cumbersome. This minimizes how often you need to stop and empty the bag during mowing.
Is a self-propelled mower necessary?
Self-propelled mowers are highly recommended for larger yards or sloped terrain. They reduce physical effort, especially models with rear-wheel drive for better traction. However, a push mower is suitable for smaller, flat lawns.
The Bottom Line
Ultimately, the best rear bagging lawn mower for you depends on your specific lawn size and terrain. Considering engine power, cutting width, and features like self-propulsion and 3-in-1 versatility will streamline your search and ensure a satisfying mowing experience.
Investing in a quality mower with reliable components, like a Briggs & Stratton engine or an OHV design, will save you time and frustration in the long run. Don’t hesitate to prioritize features that align with your needs – a larger bag capacity or rear-wheel drive can make all the difference.
