Overview

The Sun Joe MJ503M is a 14-inch manual reel mower designed for homeowners who want a quiet, emissions-free way to maintain small to medium lawns. It’s best suited for yards under 1/4 acre with relatively flat terrain and grass that’s kept at a moderate height. If you’re tired of dealing with gas, extension cords, or noisy engines, this push reel mower offers a straightforward, low-maintenance alternative that doubles as a light workout.

Who Should Buy This

  • Homeowners with small, flat lawns (under 1/4 acre): This mower shines on smaller properties where the 14-inch cutting width is practical. You won’t be pushing it for hours, and the manual operation keeps things simple.

  • Eco-conscious buyers who hate gas cans and fumes: If you want zero emissions, no oil changes, and no fuel costs, a reel mower is the cleanest option. The Sun Joe fits that bill perfectly.

  • Budget-minded shoppers looking for a sub-$150 mower: At $114.99, it’s one of the most affordable new mowers available. For the price, you get a durable steel frame and adjustable cutting heights.

  • Homeowners who want a quiet, early-morning mowing option: Reel mowers are nearly silent. You can cut grass at 6 a.m. without waking the neighbors—something no gas or electric mower can claim.

Key Features Breakdown

14-inch cutting width: This is narrow—about half the width of a typical gas walk-behind. It means more passes, but it also makes the mower lighter and easier to maneuver in tight spots, around flower beds, and along fence lines. Best for smaller lawns.

9 adjustable cutting positions: You can set the cutting height from 1/4 inch to 2 inches in small increments. This gives you fine control over grass length, but note that reel mowers struggle with grass taller than 3–4 inches. Keep up with weekly cuts to avoid clumping.

Heavy-duty steel frame: The frame is welded steel, not cheap plastic. It adds weight (about 18 pounds) but gives the mower real durability. This is a machine that can last years with basic care.

5-blade reel design: The cutting reel uses five hardened steel blades that spin against a stationary bed knife. More blades generally mean a cleaner cut, though you’ll need to keep the blades sharp for best results.

No engine, no battery, no cord: This is a pure manual mower. The only maintenance is occasional blade sharpening and bolt tightening. No spark plugs, no oil, no charging.

Pros

  1. Quiet operation: You can mow any time without disturbing anyone. The sound is a gentle whir, not a roar.
  2. Zero emissions and no fuel costs: Saves money over time and is better for the environment.
  3. Lightweight and easy to push: At 18 pounds, it’s easy to lift over obstacles or store on a wall hook.
  4. Simple, low maintenance: No engine parts to fail. Just keep the blades clean and sharp.
  5. Clean, scissor-like cut: Reel mowers slice grass rather than tearing it, which can promote healthier lawns with less browning.
  6. Very affordable: At under $120, it’s a fraction of the cost of a decent gas or electric mower.

Cons

  1. Narrow cutting width: The 14-inch deck means more passes. Expect to spend 30–45 minutes on a typical 1/4-acre lawn, versus 15–20 minutes with a 21-inch mower.
  2. Struggles with tall or wet grass: If you let the lawn get over 3–4 inches tall, the reel will clog and skip. You’ll need to bag clippings or rake after. Wet grass is a nightmare—wait for it to dry.
  3. No grass collection bag: The MJ503M does not include a catcher. You’ll either leave clippings on the lawn (good for fertilizing) or rake them up. Some users find this inconvenient.
  4. Not for uneven or bumpy terrain: Reel mowers need a relatively flat surface. On rough ground, the reel can scalp high spots and miss low spots, leaving an uneven cut.

Bottom Line

The Sun Joe MJ503M is a solid, affordable reel mower for the right buyer. If you have a small, flat lawn, want to avoid gas and noise, and don’t mind a little extra walking, this mower delivers a clean cut and years of simple service. However, it’s not a substitute for a powered mower on larger or neglected lawns. Keep your grass cut weekly, and this little reel mower will reward you with a quiet, fume-free mowing experience. For $114.99, it’s a great value for the right situation. If your yard is bigger than 1/4 acre or you let the grass get tall, look for a 16- or 18-inch reel mower—or consider a corded electric alternative.

Frequently Asked Questions

Q: Can this mower handle thick grass like Bermuda or St. Augustine?
A: It can, but only if you mow frequently—every 5–7 days during peak growing season. Thick, tough grass will dull the blades faster, so plan to sharpen the reel and bed knife at least once per season. For very thick lawns, you may need to make slower, more deliberate passes.

Q: Does the Sun Joe MJ503M come fully assembled?
A: Mostly. The handle requires some assembly (attaching the upper and lower handle sections and the crossbar). It’s straightforward and takes about 10–15 minutes with a screwdriver. No special tools needed.

Q: How do I sharpen the blades on this reel mower?
A: You can use a reel mower sharpening kit (available online) or take it to a local small-engine shop. A simple method is to apply lapping compound to the blades and spin the reel backward by hand for a few minutes. For best results, remove the reel and sharpen each blade individually with a file. Plan to sharpen once a year or whenever you notice the cut getting ragged.

How It Compares

Quick Verdict

The American Lawn Mower Company 1204-14 wins overall due to its superior customer satisfaction (4.3 stars from over 22,000 reviews), lower price, and proven reliability—making it the better value for most homeowners.

Side-by-Side Comparison

Feature Sun Joe MJ503M American Lawn Mower 1204-14
Price $114.99 $87.99
Power Source Manual (reel) Manual (reel)
Cutting Width 14 inches 14 inches
Self-Propelled No No
Best Yard Size Small (up to 1/4 acre) Small (up to 1/4 acre)
Warranty 2 years Not specified (typically 1 year)

Both mowers are manual reel models with identical cutting widths, making them suitable for small, flat lawns. The key differences lie in build quality, price, and user satisfaction.

Where Sun Joe Wins

  1. 9 adjustable cutting positions – The Sun Joe offers 9 height settings (ranging from roughly 0.5 to 1.9 inches), giving you fine control over grass length. The American Lawn Mower has only 5 positions (0.75 to 2.5 inches), so the Sun Joe is better for those who want precise cuts or very short grass.

  2. Longer warranty – Sun Joe backs the MJ503M with a 2-year warranty, compared to the American Lawn Mower’s unspecified (typically 1-year) coverage. This extra year provides peace of mind for budget-conscious buyers.

  3. Heavy-duty build claim – The Sun Joe is marketed as “heavy-duty” with a steel blade and reinforced wheels, which may appeal to buyers who expect longevity in tougher conditions (e.g., occasional thick grass or uneven terrain).

Where American Lawn Mower Wins

  1. Lower price – At $87.99, the American Lawn Mower is $27 cheaper than the Sun Joe. For a manual reel mower—a simple, low-maintenance tool—this price difference is significant, especially for budget buyers.

  2. Higher customer rating – With a 4.3-star average from over 22,000 reviews (versus Sun Joe’s 3.7 stars from 6,000 reviews), the American Lawn Mower has a proven track record of reliability and user satisfaction. Many reviews praise its sharp blades, easy assembly, and consistent cutting.

  3. 4-blade reel design – The American Lawn Mower uses a 4-blade reel (vs. Sun Joe’s likely 5-blade design, though not specified). While fewer blades may seem like a drawback, many users report that the 4-blade system cuts cleanly with less clogging in dry grass, and the simpler design means fewer parts to maintain.

Which Should You Buy?

Buy Mower A (Sun Joe) if: You want maximum cutting versatility. The 9 height settings make it ideal for lawns where you need precise control—like Bermuda grass that requires very short cuts (0.5 inches) or if you overseed and need to adjust height frequently. The 2-year warranty also suits buyers who want extra protection.

Buy Mower B (American Lawn Mower) if: You prioritize value and proven reliability. At $87.99 with a 4.3-star rating from over 22,000 users, it’s the safer choice for most small lawns. The 4-blade design is simple, sharp, and easy to maintain—perfect for homeowners who want a low-cost, low-fuss mower that just works.

Skip both if: Your lawn is larger than 1/4 acre, has thick or tall grass, or is hilly. Manual reel mowers require frequent passes and struggle with overgrowth. For those conditions, consider a gas or electric mower instead.

Quick Verdict

The American Lawn Mower Company 1815-18 wins overall due to its superior build quality, wider cutting path, higher user satisfaction rating, and proven durability over decades of use—justifying its slightly higher price.

Side-by-Side Comparison

Feature Sun Joe MJ503M American Lawn Mower 1815-18
Price $114.99 $141.98
Power Source Manual (reel) Manual (reel)
Cutting Width 14 inches 18 inches
Self-Propelled No No
Best Yard Size Small (up to 1/4 acre) Small to medium (up to 1/2 acre)

Where Sun Joe Wins

  1. Lower upfront cost – At $114.99, the Sun Joe is $27 cheaper, making it a more accessible entry point for budget-conscious buyers who want a reel mower without a major investment.

  2. More cutting height adjustments – The Sun Joe offers 9 adjustable positions (ranging from roughly 0.5 to 1.9 inches) versus the American Lawn Mower’s 5 positions. This gives finer control for users who want precise grass length, especially for specific grass types or seasonal changes.

  3. Lighter weight and easier maneuverability – Weighing approximately 15 pounds (compared to the American’s 22 pounds), the Sun Joe is noticeably easier to push, lift, and store. This is a real advantage for smaller yards with tight corners or for users with limited strength.

Where American Lawn Mower Wins

  1. Superior cut quality and efficiency – The 18-inch cutting width is 29% wider than the Sun Joe’s 14-inch path, meaning fewer passes to cover the same area. The 5-blade reel also delivers a cleaner, more scissor-like cut on grass up to 4 inches tall, reducing the need for multiple passes on thicker growth.

  2. Much higher user satisfaction and reliability – With a 4.3/5 rating from over 22,000 reviews (versus Sun Joe’s 3.7/5 from 6,000), the American Lawn Mower consistently earns praise for its durable steel construction, smooth rolling, and long lifespan. Many owners report 10+ years of use with minimal maintenance.

  3. Better build quality and warranty – The American features a heavy-gauge steel frame and sealed ball bearings in the wheels, which reduce friction and wear. Its 5-year warranty is more than double Sun Joe’s 2-year coverage, reflecting confidence in long-term performance. The larger wheels also roll more easily over uneven ground.

Which Should You Buy?

Buy Mower A (Sun Joe MJ503M) if: You have a very small yard (under 1/4 acre), want to spend under $120, and value lightweight handling and fine height adjustments over cutting width and long-term durability. It’s a good starter reel mower for occasional use.

Buy Mower B (American Lawn Mower 1815-18) if: You want a reliable, long-lasting reel mower for a small to medium yard (up to 1/2 acre), prioritize cut quality and fewer passes, and are willing to spend $27 more for a machine with a proven track record and a 5-year warranty. This is the smarter investment for regular use.

Neither is ideal if: Your yard is larger than 1/2 acre, has thick or tall grass, or you want a self-propelled or powered mower. In those cases, look at gas or electric options instead.
