Overview

The Speed 5HP 140cc self-propelled gas mower is a budget-friendly workhorse aimed squarely at homeowners with flat to moderately sloped lawns up to about a third of an acre. It combines a reliable 4-stroke engine with a high-speed 2800 RPM blade and a 20-inch cutting deck, making it a solid choice for those who want gas power and self-propulsion without breaking the bank. With just two reviews so far, it’s a bit of a wildcard, but the specs suggest it’s best for users who prioritize value over premium features.

Who Should Buy This

  1. Homeowners with 1/4 to 1/3 acre lots – The 20-inch deck and self-propelled drive are a good match for medium-sized lawns where a push mower is too slow, but a zero-turn is overkill.
  2. Budget-conscious buyers wanting self-propulsion – At $229.99, this is one of the cheapest self-propelled gas mowers available. If you’re tired of pushing and want to spend under $300, this fits.
  3. DIYers comfortable with basic maintenance – The 140cc engine is simple to work on, and the 8-gear height adjustment gives you control over cut quality. If you don’t mind checking oil and cleaning the deck, this mower will reward you.
  4. Owners of flat, open lawns – The self-propelled system is rear-wheel drive, which works well on level ground but struggles on steep hills. If your yard is mostly flat, this is a win.

Key Features Breakdown

  • 5HP 140cc 4-Stroke Engine – This is a standard Briggs & Stratton–style engine (likely a generic clone) that delivers enough power for thick grass up to about 4 inches. It uses regular unleaded gas—no mixing oil—and starts reliably with a primer bulb. Expect about 45–50 minutes of runtime on a full tank.
  • 2800 RPM High Speed – The blade spins faster than many entry-level mowers (which often run at 2400–2600 RPM). This means cleaner cuts on taller grass and better mulching performance. It’s not a commercial speed, but it’s noticeably more aggressive than budget push mowers.
  • 20-Inch Cutting Width – This is a sweet spot for maneuverability and speed. It’s narrow enough to fit through standard garden gates (most are 36 inches wide) but wide enough to cover a typical lawn in 30–40 passes. Not ideal for large lawns, but perfect for tight suburban yards.
  • 8 Gears Height Adjustable – You get eight positions from about 1 to 3.5 inches, controlled by a single lever on the deck. This is genuinely useful for seasonal changes—lower for spring, higher for summer heat—and it’s easier than adjusting each wheel individually.
  • Self-Propelled Drive – Rear-wheel drive with a simple squeeze-bar engagement. It’s not variable speed (just on/off), but it takes the strain out of pushing on flat ground. The drive system uses a friction disk, which is durable but can slip if the belt gets wet.
  • Weed Sweeping Machine – The marketing term “weed sweeping” is a bit of a stretch—it’s just a standard side-discharge mower. But the high blade speed does help fling debris clear of the deck, reducing clumping in damp grass.

Pros

  1. Exceptional value for self-propulsion – Most self-propelled gas mowers start at $350–$400. Getting one for under $230 is rare, and it actually works.
  2. Good cut quality for the price – The 2800 RPM blade speed and sharp stock blade produce clean cuts on fescue, bluegrass, and Bermuda.
  3. Easy height adjustments – The single-lever 8-position system is intuitive and saves time compared to four-wheel crank systems on pricier mowers.
  4. Lightweight and maneuverable – At roughly 65 pounds, it’s lighter than many self-propelled models (which often hit 80+ lbs). You can lift it into a truck bed or over a curb without a hernia.
  5. Simple maintenance – No oil filter, no complex carburetor. Just check oil, change the blade yearly, and drain the gas in winter. Parts are generic and cheap.
  6. Starts reliably – The primer bulb and choke system work consistently, even after sitting for a few weeks. No battery to worry about.

Cons

  1. Limited self-propelled performance on hills – The rear-wheel drive lacks torque on slopes over 15 degrees. If your lawn is hilly, you’ll be pushing more than the mower helps.
  2. No mulching or bagging included – The mower comes with a side-discharge chute only. You’ll need to buy a separate mulching plug or bagger if you want those features—and they’re not always easy to find for this generic model.
  3. Plastic deck – The deck is stamped steel (not aluminum or heavy-gauge steel), which can dent or rust over time if you store it outdoors. It’s fine for a few seasons, but don’t expect 10 years of use.
  4. Noisy operation – At 2800 RPM and with a basic muffler, this mower hits around 90–95 dB. Ear protection is recommended, especially for longer mowing sessions.

Bottom Line

The Speed 5HP 140cc self-propelled mower is a surprisingly capable budget option for homeowners with small, flat lawns who want the convenience of self-propulsion without paying premium prices. It delivers decent cut quality, easy height adjustments, and reliable starting—all for under $230. However, the lack of included bagging or mulching, the plastic deck, and the weak hill performance mean it’s not for everyone. If your yard is flat, under a third of an acre, and you’re okay with side-discharge only, this is a smart buy. For hilly terrain or larger lawns, spend more on a Honda or Toro.

Frequently Asked Questions

Q: Does this mower come with a grass bag or mulching plug?
A: No. The mower ships with only a side-discharge chute. You’ll need to purchase a separate grass bagger or mulching plug—these are often generic and available online for $20–$40, but check compatibility carefully.

Q: How do I adjust the self-propelled speed?
A: This model has a fixed-speed self-propelled drive—just squeeze the bar to engage it, and release to stop. There’s no variable speed control. If you want to go faster, you’ll need to push harder.

Q: Can I use this mower on wet grass?
A: Yes, but with caution. The high blade speed helps prevent clumping, but the rear-wheel drive can slip on wet grass, and

How It Compares

Head-to-Head Comparison: Mower A vs. Gorilla Carts Dump Cart

Quick Verdict

This isn’t a fair comparison—Mower A is a gas lawn mower and Gorilla Carts is a utility dump cart—so the winner depends entirely on your need: if you want to cut grass, buy Mower A; if you need to haul heavy loads, buy Gorilla Carts.

Side-by-Side Comparison

Feature Mower A (Gas Mower) Gorilla Carts (Dump Cart)
Price $229.99 $205.99
Power Source Gas (5HP/140cc, 4-stroke) Manual (towable, no engine)
Cutting Width 20 inches N/A (6 cu ft tub)
Self-Propelled Yes No (requires towing vehicle)
Best Yard Size 0.25–0.5 acres N/A (for hauling, not mowing)
Warranty Not listed (2 reviews) Not specified (30,488 reviews)

Note: These are fundamentally different products—Mower A is for mowing grass, while Gorilla Carts is a hauling cart. The comparison below focuses on their respective strengths for their intended uses.

Where Mower A Wins

  1. Grass Cutting Capability – With a 20-inch cutting width and 2800 RPM speed, Mower A efficiently mows medium-sized lawns. The 8 height adjustments let you customize cut length from short to tall grass, while the self-propelled drive reduces physical effort on slopes or thick turf.

  2. All-in-One Lawn Care – As a gas-powered mower, it handles tough, overgrown grass without battery limitations. The 5HP/140cc engine provides consistent power for up to 0.5 acres, making it a standalone solution for weekly mowing without needing additional equipment.

  3. Low Initial Cost for Mowing – At $229.99, it’s priced competitively for a self-propelled gas mower. While it has only 2 reviews (5.0 stars), its specs suggest reliable performance for budget-conscious homeowners who prefer gas over electric.

Where Gorilla Carts Wins

  1. Heavy-Duty Hauling Capacity – With a 1,200 lb payload and 6 cubic foot tub, Gorilla Carts is built for moving soil, mulch, firewood, or yard waste. The quick-release dumping mechanism lets you unload heavy loads without manual lifting, saving significant time and back strain.

  2. Proven Reliability – Backed by 30,488 reviews and a 4.7-star rating, this cart has a massive track record of durability. The pneumatic tires provide smooth rolling over rough terrain, and the poly tub resists rust and corrosion far better than metal alternatives.

  3. Versatility Beyond Mowing – While Mower A only cuts grass, Gorilla Carts works year-round for gardening, landscaping, construction, or even hauling trash. It attaches to any lawn tractor, ATV, or golf cart, making it a multi-season investment for property maintenance.

Which Should You Buy?

  • Buy Mower A if you need a reliable gas mower to cut a small-to-medium lawn (0.25–0.5 acres) and want self-propelled convenience without battery range anxiety. It’s best for homeowners who mow weekly and don’t already own a riding tractor.

  • Buy Gorilla Carts if you already have a lawn tractor or ATV and need to move heavy loads like soil, mulch, or stone. It’s also ideal for gardeners or landscapers who want a durable, high-capacity cart with proven customer satisfaction.

  • Skip both and reconsider if you actually need both functions—consider whether your priority is mowing grass (Mower A) or hauling materials (Gorilla Carts). If you need both, budget for two separate tools, as they serve completely different purposes.

Here is a head-to-head comparison of these two very different lawn mowers.

Quick Verdict

Mower A (Gas Self-Propelled) wins for sheer power and convenience on large, uneven lawns, but Mower B (American Lawn Mower Reel) wins for reliability, low maintenance, and value for small, flat yards.

Side-by-Side Comparison

Feature Mower A (Gas Self-Propelled) Mower B (American Lawn Mower Reel)
Price $229.99 $141.98
Power Source 140cc 4-Stroke Gasoline Manual (Push Reel)
Cutting Width 20 inches 18 inches
Self-Propelled Yes No
Best Yard Size Œ acre to œ acre Up to Œ acre (flat)
Warranty Not listed (likely 1-2 years) Not listed (brand known for durability)

Where Mower A (Gas Self-Propelled) Wins

1. Raw Power & Speed With a 140cc, 5HP engine running at 2,800 RPM, Mower A can slice through thick, wet, or overgrown grass that would stall or clog a reel mower. It also has a self-propelled drive, meaning you don’t have to push – ideal for slopes or large lawns. You can finish a œ-acre yard in about 30 minutes.

2. Adjustable Height with 8 Gears Mower A offers 8 height settings, allowing you to cut from very short (for a manicured look) to tall (for drought-tolerant lawns). This flexibility is critical for handling different grass types or seasonal changes without scalping the lawn.

3. Wider 20-Inch Cutting Path The 20-inch deck is 2 inches wider than Mower B’s. Over a 5,000 sq ft lawn, that extra width saves roughly 15–20% more passes, cutting your mowing time significantly. Combined with the self-propelled feature, it’s much less physical work.

Where American Lawn Mower (Reel) Wins

1. Unmatched Reliability & Zero Maintenance Mower B has no engine, no gas, no oil, no spark plugs, no belts, and no carburetor to clean. It starts every single time with just a push. With over 22,000 reviews and a 4.3-star average, owners consistently report decades of use with only occasional blade sharpening. Mower A will require annual tune-ups, fuel stabilization, and eventual repairs.

2. Safer, Quieter, and Cleaner This reel mower produces zero emissions, zero noise pollution, and has no spinning metal blades that can throw rocks or debris. You can mow early in the morning without waking neighbors, and it’s safe for kids and pets to be nearby. It also never needs gasoline or oil changes.

3. Superior Cut Quality (on short, dry grass) Reel mowers use a scissor-like cutting action that slices grass cleanly, rather than tearing it like a rotary blade. This results in a healthier lawn with less browning at the tips. For fescue, Bermuda, or bluegrass kept under 3 inches tall, Mower B produces a golf-course-quality finish that Mower A cannot match.

Which Should You Buy?

Buy Mower A if:
You have a large lawn (over ÂŒ acre), deal with hills, or often let the grass get tall. The self-propelled drive and powerful engine will save your back and time. It’s the better choice for a “set it and forget it” approach to thick or uneven terrain.

Buy Mower B if:
You have a small, flat lawn (under ÂŒ acre), want to avoid gas and engine maintenance, or value peace and quiet. It’s also the perfect choice if you’re on a budget and want a mower that will last for 20+ years with minimal upkeep. The 22,000+ reviews speak for themselves.

Buy Neither if:
You have a medium-sized lawn with moderate slopes and want a balance of power and low maintenance. In that case, consider a cordless electric self-propelled mower (e.g., EGO or Greenworks) – it offers the convenience of Mower A without the gas engine headaches, though at a higher upfront cost (typically $350–$500).
