12inch Manual Push Reel Lawn Mower, Adjustable Heights Push Lawn Sweeper with 6 gal Collection Bag, Efficient Grass Catcher Review

Quick Verdict

Neither mower wins overall because they are completely different tools—Mower A is a manual reel mower for small, flat lawns, while Mower B is a string trimmer/edger for detail work—so the right choice depends entirely on whether you need a primary mower or a finishing tool.

Side-by-Side Comparison

Where Mower A Wins

1. True lawn mowing capability – Mower A cuts grass across an entire lawn using a reel blade mechanism, making it a primary mower. Mower B is a string trimmer designed only for edges, weeds, and small patches—it cannot replace a lawn mower for full-yard cutting.

2. Zero operating costs – No electricity, gas, oil, or replacement trimmer line needed. The manual push design means you pay $51.99 once and never buy fuel or cords again. Mower B requires a power outlet and replacement spools ($5–$10 per pack).

3. Quiet, clean, and low maintenance – No engine noise, no emissions, and no spark plugs or air filters to replace. The reel mower’s blades only need occasional sharpening (every 1–2 seasons), while the BLACK+DECKER trimmer has a motor and auto-feed mechanism that can jam or wear out.

Where BLACK+DECKER Wins

1. Vastly superior cutting versatility – The 14-inch string trimmer handles tall weeds, thick grass, and overgrown edges that a manual reel mower cannot cut. It also converts to an edger for crisp sidewalk/driveway lines. Mower A will struggle or stall on any grass taller than 4 inches.

2. Proven reliability and support – With 17,279 ratings and a 4.4-star average, this BLACK+DECKER model is a market leader. The 2-year warranty and widely available replacement parts (spools, heads) mean you can fix it easily. Mower A has only 1 review and no established support network.

3. Lightweight and easy for detail work – At just 6.5 amps and a trimmer-style design, it’s ideal for reaching under fences, around flower beds, and along curbs. Mower A is heavier (about 15–20 lbs) and cannot access tight spaces or uneven terrain where a reel mower would scalp or miss grass.

Which Should You Buy?

Buy Mower A if: You have a small, flat lawn (under 2,000 sq ft) with short, well-maintained grass, want zero electricity costs, and prefer a quiet, eco-friendly mowing experience. It’s perfect for a tiny backyard or as a backup manual mower for emergencies.

Buy Mower B if: You already own a primary lawn mower (push or riding) and need a reliable trimmer/edger for cleanup work around obstacles. It’s also the better choice if your lawn has overgrown patches, weeds, or uneven edges where a reel mower would fail.

Neither if: You need a single tool for mowing a medium-to-large lawn (over 1/4 acre). In that case, buy a gas or electric push mower (around $150–$300) and add a trimmer separately. These two products serve different roles and cannot substitute for each other.

Quick Verdict

Mower A wins for tiny, eco-conscious yards on a budget; Mower B wins for nearly everyone else due to proven reliability, electric power, and a massive user base backing its performance.

Side-by-Side Comparison

Where Adjustable Wins

1. Zero Operating Cost & Emissions – No gas, no electricity, no charging. Mower A runs on human power alone, saving you $0 in fuel or electricity over its lifetime. Greenworks requires electricity or battery replacement ($50–$100 every 2–3 years).
2. Quiet & Maintenance-Free – At just 55–65 dB (whisper-quiet), you can mow at dawn without waking neighbors. No oil changes, spark plugs, or air filters. Greenworks has a motor and blade that need occasional cleaning and potential bearing replacement.
3. Ultra-Compact Storage – At 12 inches wide, Mower A folds flat and fits in a closet, under a bed, or in a car trunk. Greenworks takes up garage floor space and requires assembly (handle, grass bag).

Where Greenworks Wins

1. Proven Reliability & Scale – 12,958 reviews with a 4.2-star average means thousands of users have verified it works. Mower A has exactly 1 review—a gamble on quality. Greenworks is a major brand with replacement parts available at Home Depot and Amazon.
2. Faster, Easier Cutting – With a 16–20 inch cutting width (vs. 12 inches), Greenworks covers 60–80% more grass per pass. It also cuts uneven grass, thick weeds, and damp lawns without stalling, while a reel mower bogs down on anything over 4 inches tall.
3. Better Grass Management – Greenworks’ bagger typically holds 10–15 gallons (vs. 6 gallons on Mower A) and uses a powerful vacuum to suck up clippings. Mower A’s 6-gallon bag fills fast and requires frequent emptying, plus it struggles with mulching or side-discharge.

Which Should You Buy?

• Buy Mower A if: You have a tiny, flat lawn under 1,000 sq. ft. (like a postage-stamp front yard), you want zero emissions and zero noise, and you’re willing to mow every 5–7 days in dry conditions. It’s also a great backup mower for trimming edges.
• Buy Mower B if: Your yard is 1,000–8,000 sq. ft. (typical suburban lot), you want to finish mowing in 30 minutes or less, and you need to handle occasional tall grass, damp conditions, or uneven terrain. The 4-year warranty and brand support make it a safer long-term investment.
• Buy neither if: Your yard is over ¼ acre or hilly—look for a self-propelled gas or battery model instead. For anything in between, Greenworks is the clear winner for reliability and speed.
