Overview

The Grass 20-Inch Manual Reel Mower is a return to the simple, quiet, and effective way of cutting grass. Designed specifically for small to medium-sized lawns (under 1/4 acre), this lightweight push mower offers an eco-friendly alternative to gas or electric models without sacrificing a clean, precise cut. It’s the perfect tool for the homeowner who values a morning workout, a peaceful neighborhood, and zero dependency on fuel or extension cords.

Who Should Buy This

  1. The Eco-Conscious Homeowner – If you want to eliminate gas, oil, and battery disposal from your lawn care routine, this mower is your ticket. It produces zero emissions and runs on your own two feet. Perfect for those with a small yard who want to reduce their carbon footprint.

  2. The Quiet-Neighborhood Dweller – Live close to neighbors, have a small child napping, or just hate the roar of a gas engine? This mower is whisper-quiet. You can mow at 7 AM on a Saturday without waking anyone up. The only sound is the whir of the spinning blades.

  3. The Small-Lot Gardener – If your lawn is a postage stamp—say, a 40x50 foot patch in a suburban or urban setting—this is your ideal machine. It’s nimble, easy to store, and won’t require a garage bay. You can finish the job in under 30 minutes with minimal effort.

  4. The Budget-Conscious Buyer – At just over $50, this mower is a fraction of the cost of even a basic electric model. If you’re looking for a reliable, low-maintenance tool that won’t break the bank, this is a no-brainer. No fuel, no electricity, no expensive repairs.

Key Features Breakdown

  • 20-Inch Cutting Width: This is the sweet spot for manual mowers. It’s wide enough to cover ground efficiently (a 20-inch swath means fewer passes), but narrow enough to maneuver through gates and around flower beds. It’s a good balance for small to medium lawns.

  • Lightweight & Easy to Maneuver: This mower is noticeably lighter than many reel mowers on the market. You can lift it over a garden hose, turn it on a dime, and push it uphill without breaking a sweat. This is a major plus for older users or anyone with a yard that has curves and obstacles.

  • Eco-Friendly and Quiet Operation: This isn’t just a marketing tagline. With no motor, there’s zero noise pollution and zero emissions. It’s also safer for pets and kids—no hot engines, no sharp metal blades spinning at high speed. Just a gentle scissor-like cut.

  • Manual Reel Mechanism: The reel spins against a stationary bed knife, creating a clean scissor cut. This is better for grass health than a gas mower’s ragged tear. The grass heals faster and looks greener. The key is to keep the blades sharp and mow before the grass gets too tall.

  • Price Point ($51.01): This is a steal for a functional, well-built reel mower. You’ll spend more on a single tank of gas for a riding mower. It’s an entry-level price that doesn’t feel cheap in the hand—the frame is sturdy, and the wheels roll smoothly.

Pros

  1. Incredibly Quiet – Mowing becomes a peaceful, meditative task. You can hear birds, your kid playing, or your favorite podcast without headphones.
  2. Zero Operating Costs – No gas, no oil, no electricity, no battery replacements. The only cost is an occasional blade sharpening (every few seasons).
  3. Lightweight and Easy to Store – At roughly 20 pounds, you can hang it on a wall hook or stash it in a corner of the shed. No bulky battery charger or gas can needed.
  4. Clean, Healthy Cut – The scissor action of a reel mower is gentler on grass than rotary blades. It reduces browning at the tips and promotes a thicker, greener lawn over time.
  5. Simple Maintenance – There are no spark plugs, filters, or carburetors to mess with. A quick blade adjustment and occasional lubrication of the wheels is all it needs.
  6. Safe for Everyone – No thrown debris, no hot mufflers, no electric cords to trip over. It’s a low-risk tool for families with kids and pets.

Cons

  1. Not for Tall or Thick Grass – This mower struggles with grass over 4 inches tall. If you let your lawn get shaggy, you’ll be making multiple passes or fighting to push it through. It’s best for regular weekly mowing.
  2. Lacks a Grass Catcher – The basic model does not include a bag. You’ll need to rake or leave the clippings (which is actually great for the lawn as natural fertilizer). If you want a pristine, clippings-free finish, you’ll need to buy a separate catcher or plan for a second pass.
  3. Requires a Little Effort – It’s a manual mower. On flat, well-maintained turf, it’s easy. On bumpy ground or with damp, heavy grass, you’ll feel the resistance. It’s a workout, not a chore.
  4. Blades Need Sharpening – Like any reel mower, the cutting performance fades over time. You’ll need to sharpen or replace the reel every year or two depending on use. It’s not hard, but it’s an extra step some buyers ignore.

Bottom Line

The Grass 20-Inch Manual Reel Mower is a fantastic choice for the right homeowner. If you have a small, flat lawn under 1/4 acre, value peace and quiet, and want to ditch the gas can for good, this mower delivers an excellent cut at a fraction of the cost of powered alternatives. It’s not for everyone—if you have a large, hilly, or overgrown yard, look elsewhere. But for the eco-minded, budget-conscious, or simply tidy-minded gardener, it’s a reliable, low-maintenance tool that will give you years of service. I recommend it without hesitation for its intended use.

Frequently Asked Questions

Q: How often do I need to sharpen the blades? A: With regular use on a typical lawn (once a week during growing season), you’ll likely need a light sharpening every 1-2 years. You can buy a sharpening kit or take the reel to a local small engine shop. If you notice the grass being torn instead of cut cleanly, it’s time.

Q: Will it work on St. Augustine or thick Bermuda grass? A: It will work, but with caveats. These thick, aggressive grasses require a very sharp reel and a low cutting height. You’ll need to mow frequently (every 5-7 days) and keep

How It Compares

Quick Verdict

Neither mower is a direct competitor—Mower A is a manual reel mower for precise, eco-friendly grass cutting, while Mower B is a string trimmer/edger for trimming edges and weeds—so the winner depends entirely on whether you need a primary mower or a secondary tool for finishing work.

Side-by-Side Comparison

Feature Mower A (Manual Reel Mower) Mower B (BLACK+DECKER String Trimmer)
Price $51.01 $59.00
Power Source Manual (push) Electric (corded, 6.5-amp)
Cutting Width 20 inches 14 inches
Self-Propelled No No
Best Yard Size Small to medium (up to 1/4 acre) Edging/trimming only (not for full lawn)
Warranty Not specified (likely limited) 2-year limited (BLACK+DECKER standard)

Where Grass Wins

  1. Primary mowing capability: Mower A cuts a full 20-inch swath and is designed to replace a gas or electric mower on small, flat lawns. Mower B is only a trimmer—it cannot mow an entire lawn efficiently.
  2. Eco-friendly, zero emissions: No gas, oil, or electricity needed. Mower A produces zero noise pollution and zero exhaust, making it ideal for early-morning or quiet-neighborhood mowing.
  3. Lightweight and low maintenance: At roughly 20–25 lbs (typical for reel mowers), Mower A is easier to carry and store than most power mowers. It requires no spark plugs, oil changes, or fuel mixing—just occasional blade sharpening.

Where BLACK+DECKER Wins

  1. Versatility for trimming and edging: Mower B is a 2-in-1 string trimmer and edger, allowing you to clean up along fences, flower beds, sidewalks, and driveways. Mower A cannot edge or reach tight spaces.
  2. Proven reliability and reviews: With 17,279 ratings at 4.4 stars, the BLACK+DECKer BESTA510 has widespread user validation. Mower A has only 1 review, making its quality uncertain.
  3. Ease of use for overgrown grass: Mower B’s 6.5-amp motor and auto-feed string handle thick weeds and tall grass that would stall a manual reel mower. Mower A struggles with grass over 4–5 inches tall.

Which Should You Buy?

Buy Mower A if… you have a small, flat lawn under 1/4 acre with fine grass (e.g., Bermuda or fescue), you want zero emissions and near-silent operation, and you don’t mind physical effort. It’s ideal for budget-conscious, eco-focused homeowners who value a clean, scissor-like cut over convenience.

Buy Mower B if… you already own a primary mower (gas or electric) and need a reliable, lightweight trimmer for edges, under fences, and around obstacles. It’s perfect for maintaining a manicured look in yards of any size, and its 17,000+ positive reviews make it a safe bet.

Buy neither if… you need a single tool to mow an entire lawn larger than 1/4 acre or with uneven terrain. In that case, consider a self-propelled gas or electric mower (e.g., a 21-inch Toro or EGO mower) instead of either of these specialized tools.

Quick Verdict

If you want a nearly silent, zero-emission workout for a tiny, flat lawn, Mower A wins for novelty and price; but for any real-world grass-cutting task, Mower B (Greenworks) is the clear overall winner due to proven reliability, massive user consensus, and far superior cutting performance.

Side-by-Side Comparison

Feature Mower A (Manual Reel) Mower B (Greenworks)
Price $51.01 $79.99
Power Source Human power (push reel) Electric (corded or battery? — likely corded at this price)
Cutting Width 20 inches 20 inches (typical for this model)
Self-Propelled No No
Best Yard Size Under 1/4 acre, flat, fine-bladed grass Up to 1/3 acre (corded) or 1/4 acre (battery)
Warranty Typically 1 year (limited) 4 years (on Greenworks electric mowers)

Note: Greenworks offers multiple 20-inch models. The $79.99 price point strongly suggests a corded electric model (e.g., 25022), which provides unlimited runtime but requires an extension cord.

Where Grass Wins (Mower A)

  1. Absolute Quiet & Eco-Friendliness – Mower A produces zero noise pollution and zero emissions. You can mow at dawn without waking neighbors, and there’s no gas, oil, or electricity involved. It’s the ultimate green machine.
  2. Lightweight & Low Maintenance – At roughly 20–25 lbs, this reel mower is significantly lighter than any electric mower. No spark plugs, no oil changes, no batteries to charge, and no cords to manage. Just sharpen the blades once a season.
  3. Safety for Kids & Pets – With no spinning electric blades or flying debris from high-speed rotors, a manual reel mower is far safer if a child or pet runs into the cutting path. The cutting action is slower and less violent.

Where Greenworks Wins (Mower B)

  1. Proven Track Record – With 12,958 reviews and a 4.2-star rating, Greenworks has been tested by tens of thousands of real users. Mower A has exactly 1 review. You know what you’re getting with Greenworks: reliable cutting, easy starting, and good customer support.
  2. Superior Cutting Power & Versatility – A reel mower struggles with tall grass, thick weeds, or damp conditions. Greenworks’ electric motor spins a rotary blade at high RPM, easily slicing through overgrown lawns, tough Bermuda grass, and even small sticks. It handles uneven terrain much better.
  3. Better Warranty & Support – Greenworks offers a 4-year warranty compared to Mower A’s typical 1-year (or less). That’s a huge difference in long-term value. Plus, replacement blades and parts are widely available for Greenworks; finding parts for a generic $51 reel mower may be difficult.

Which Should You Buy?

Buy Mower A (Manual Reel) if:

  • You have a very small, flat lawn (under 2,000 sq ft) with fine grass like fescue or rye.
  • You want a quiet, zero-emission workout and don’t mind mowing more frequently (reel mowers require cutting every 3–4 days).
  • Your budget is extremely tight and you’re willing to accept limited performance for the lowest possible price.

Buy Mower B (Greenworks) if:

  • You have a typical suburban lawn (up to 1/3 acre) with mixed grass types, occasional weeds, or uneven ground.
  • You want a reliable, low-effort mowing experience that handles tall grass and damp conditions without stalling.
  • You value a proven product with thousands of positive reviews and a 4-year warranty over a cheap, unproven alternative.

Buy Neither if:

  • Your lawn is over 1/3 acre or hilly. In that case, invest in a self-propelled gas or battery mower (e.g., Greenworks 80V or Toro Recycler). Both of these 20-inch push mowers will be frustrating on large or steep yards.
