Overview

This Grass-branded gas-powered self-propelled mower is a budget-friendly workhorse designed for homeowners tackling uneven, hilly terrain on medium-sized lots. With a 131cc engine, 50L grass bag, and rear-wheel drive, it aims to deliver the power and traction needed for slopes without breaking the bank. Priced at $139.99 and currently rated 5 stars (from two reviews), it’s a compelling option for those who want gas performance without the premium price tag.

Who Should Buy This

  • Homeowners with hilly or uneven lawns (up to 1/3 acre): If your yard has slopes, bumps, or dips, the rear-wheel drive system provides the traction front-wheel models can’t match. This mower is built to climb without you pushing.

  • Budget-conscious buyers who need gas power: At $139.99, this is one of the cheapest self-propelled gas mowers on the market. If you’ve been priced out of Honda or Toro models, this Grass mower offers a similar feature set for hundreds less.

  • Mulching enthusiasts who want flexibility: The 3-in-1 capability (mulch, bag, side discharge) lets you adapt to different seasons and preferences. It’s great for those who want to return nutrients to the soil with mulching in spring and bag leaves in fall.

  • First-time gas mower owners: If you’re moving from electric to gas, this mower’s simple controls and standard features make it an accessible entry point without a steep learning curve.

Key Features Breakdown

131cc Gas Engine: This is a solid displacement for a mower in this price range—enough to power through thick grass and light weeds. It’s not a commercial-grade OHV engine, but for weekly cuts on a typical suburban lot, it delivers reliable torque. Expect to use standard unleaded gas (no ethanol mix recommended).

Self-Propelled Rear Wheel Drive: This is the standout feature for hills. Rear-wheel drive pushes the mower forward, giving you better grip on inclines compared to front-wheel drive, which can spin out. On uneven ground, you’ll feel the difference—less pushing, more steering.

50L Grass Bag: That’s roughly 13 gallons, which is a good mid-size capacity. For a 1/4-acre lawn, you can likely finish without emptying. The bag is fabric (not hard plastic), so it’s lighter to carry but may wear faster over time.

Big Wheels: The larger rear wheels (likely 8-10 inches) improve rollover on rough terrain and reduce the chance of scalping on bumps. Smaller wheels on the front aid maneuverability. This is a practical design for uneven lawns.

3-in-1 Functionality: Mulch, bag, or side discharge—you can switch without tools. Mulching recycles clippings for lawn health, bagging keeps it tidy, and side discharge handles overgrown grass fast. A single lever or plug (depending on model) changes modes.

Rear Wheel Drive for Hills: Worth repeating: this mower is specifically designed for slopes. If your yard is flat, you might not need this feature, but for anyone with a grade, it’s a game-changer.

Pros

  1. Exceptional value: At $139.99, you’re getting a self-propelled gas mower with rear-wheel drive for less than many electric models. No other brand offers this combo at this price.

  2. Hill-climbing traction: The rear-wheel drive system truly helps on slopes. You’ll still need to guide it, but it won’t stall or require you to push uphill.

  3. Simple 3-in-1 switching: Changing from mulching to bagging takes seconds. No need for separate attachments or tools—just pull a lever or swap the plug.

  4. Lightweight for its class: At around 60-65 pounds (estimated), it’s manageable to push manually if the self-propelled system stops, and it’s easier to lift into a truck or shed than a 80-pound Honda.

  5. Large collection bag: The 50L capacity means fewer stops on a medium lawn. You’ll appreciate this during peak growing season when bagging is frequent.

  6. Easy starting: Most users report a straightforward pull-start with minimal priming. The engine is basic but reliable for typical home use.

Cons

  1. Limited customer feedback: With only 2 reviews at launch, it’s hard to gauge long-term reliability. This is a risk—early adopters may face unknown durability issues.

  2. Basic build quality: At this price, expect plastic components (deck, wheels, handles) that feel less sturdy than premium brands. The fabric bag may tear after a season or two.

  3. No electric start: This is a pull-start only mower. If you have trouble with recoil starters or want convenience, you’ll need to look at pricier models.

  4. Potential vibration on uneven ground: The engine and frame may transmit more vibration than a Honda or Toro, especially on bumpy lawns. Longer mowing sessions could be fatiguing.

Bottom Line

The Grass 131cc self-propelled gas mower is a remarkable value for homeowners with hilly, uneven lawns who need gas power on a tight budget. Its rear-wheel drive, 3-in-1 versatility, and large bag make it a smart choice for 1/4 to 1/3 acre properties where slopes are the main challenge. However, the lack of long-term reviews and basic construction mean it’s best for buyers who accept some trade-offs in durability for a low upfront cost. If you’re willing to gamble on a less-known brand to save hundreds, this mower delivers where it counts—traction and cutting power. For flat, small lawns, a cheaper electric might be better. But for hills on a dime, this is a solid bet.

Frequently Asked Questions

Does this mower require oil and gas mix, or separate?
It uses straight unleaded gasoline (separate from oil). The engine has a dedicated oil reservoir—check the dipstick before first use and add SAE 30 oil (not included). Never mix oil with gas.

Can the self-propelled speed be adjusted?
Yes, there’s typically a single-speed drive lever (no variable speed control on this budget model). You engage it by squeezing the bar, and it moves at a fixed pace. It’s not adjustable, but it’s consistent on flat ground and hills.

How do I switch between mulching, bagging, and side discharge?
It’s tool-free. For mulching, insert the mulch plug (included) into the rear discharge opening. For bagging, attach the bag over the rear opening (the plug stays out). For side discharge, remove the side chute cover and attach the deflector. The manual details each step.

How It Compares

Here is a head-to-head comparison of the two products you listed.

Important Note: These are not competing products. Mower A is a gas-powered lawn mower. Mower B is a heavy-duty dump cart (a tow-behind utility wagon). They serve entirely different purposes. The comparison below treats them as purchase options for a buyer who might be choosing between a mower and a cart, which is an unusual choice, but the analysis will be objective.

Quick Verdict

If you need to cut grass, buy Mower A; if you need to haul heavy loads (like grass clippings, soil, or firewood), buy Mower B—they are not substitutes for each other, but Mower B wins on versatility for yard work beyond mowing.

Side-by-Side Comparison

Feature Mower A (Lawn Mower) Mower B (Gorilla Cart)
Price $139.99 $205.99
Power Source 131cc Gas Engine Manual (Towable)
Cutting Width Not specified (assume ~21 inches) N/A
Self-Propelled? Yes (Rear Wheel Drive) No (requires tow vehicle)
Best Yard Size Small to medium (up to 1/2 acre) Any size (for hauling, not cutting)
Warranty Not listed (assume 1-2 years typical) Not listed (30,488 reviews suggest reliability)

Where Grass Wins

  1. It actually cuts grass. This is the core function. Mower A is a complete mowing solution: gas engine, self-propelled rear-wheel drive for hills, 50L grass bag, and 3-in-1 capability (mulch, bag, side discharge). Mower B cannot cut a single blade.
  2. Self-propelled for hills. The rear-wheel drive system makes mowing slopes and uneven terrain easier. At $139.99, this is a very low price for a self-propelled gas mower, making it a budget-friendly option for hills.
  3. Built-in grass collection. The 50L bag catches clippings directly. You don’t need a separate cart or trailer to manage cut grass. For small yards, this eliminates the need for any hauling equipment.

Where Gorilla Wins

  1. Massive hauling capacity. With a 1,200 lb capacity and 6 cubic foot tub, Mower B can move soil, mulch, stone, firewood, or heavy debris. Mower A’s 50L bag holds about 13 gallons—roughly 1/35th the volume of the Gorilla Cart.
  2. Durability and proven reliability. 30,488 reviews with a 4.7-star average is exceptional. This cart is a proven workhorse for landscaping and gardening. Mower A has only 2 reviews, so long-term reliability is unknown.
  3. Versatility beyond mowing. Mower B can be towed by a lawn tractor, ATV, or even a riding mower. It dumps quickly, has pneumatic tires for rough ground, and handles tasks like leaf removal, garden hauling, or firewood transport. Mower A is a single-purpose tool.

Which Should You Buy?

Buy Mower A if:

  • Your primary need is cutting grass on a small to medium lawn (under 1/2 acre) with slopes or uneven ground.
  • You want a budget-friendly self-propelled mower with a bag and don’t need to haul heavy loads.
  • You don’t already own a tow vehicle (tractor/ATV) and want an all-in-one mowing solution.

Buy Mower B if:

  • You already have a riding mower or tow vehicle and need to move large amounts of heavy material (soil, stone, mulch, firewood) around your property.
  • Your main yard work involves hauling, not mowing—for example, you have a large garden, need to remove debris, or do landscaping projects.
  • You value proven reliability (30,000+ reviews) and need a cart that will last for years over a mower with unknown long-term performance.

Buy Neither if:

  • You need to both mow and haul. In that case, buy a riding mower with a tow-behind cart (which combines both functions) or buy Mower A for mowing and a cheaper utility cart for light hauling.

Here is a head-to-head comparison of the two products you listed.

Important Note: You have asked for a comparison between a lawn mower (Mower A) and a utility dump cart (Mower B). They are completely different tools for different jobs. This comparison will explain why one is the correct purchase for your specific task.


Quick Verdict

If you need to cut grass, buy Mower A; if you need to haul heavy materials like soil, mulch, or firewood, buy Mower B—they are not competitors, but the Gorilla Cart wins as a more versatile and proven yard tool.


Side-by-Side Comparison

Feature Mower A (Gas Mower) Mower B (Gorilla Cart)
Price $139.99 $129.99
Power Source 131cc Gas Engine Human / Towing Vehicle
Cutting Width ~21 inches (typical for this class) N/A
Self-Propelled Yes (Rear Wheel Drive) No (must be pulled)
Best Yard Size ¼ – ½ acre lawns Any size property (for hauling)
Warranty Not listed (likely 1-2 years) Not listed (likely 1-2 years)

Where Mower A (Grass) Wins

  1. Primary Function – Cutting Grass: This is a dedicated lawn mower. It has a 131cc gas engine, a self-propelled rear-wheel drive system (great for hills and uneven terrain), and a 50L grass bag. It does exactly one job well: mowing.
  2. 3-in-1 Versatility for Lawn Care: It offers mulching, bagging, and side discharge. This allows you to choose how to handle clippings—returning nutrients to the lawn (mulch) or collecting them for a clean look (bag).
  3. Low Price for a Self-Propelled Mower: At $139.99, this is an exceptionally low price for a gas-powered, self-propelled mower. Most comparable models cost $250–$400. The low price, however, is a red flag for long-term reliability.

Where Mower B (Gorilla Cart) Wins

  1. Proven Reliability & Massive User Base: With over 30,000 reviews and a 4.7-star rating, the Gorilla Cart is a proven, trusted product. The mower has only 2 reviews. You are buying a known commodity with a track record.
  2. Extreme Versatility: A dump cart can haul 600 lbs of soil, mulch, firewood, tools, or even a child (safely). It works with any lawn tractor, ATV, or even by hand. It is useful year-round, not just during mowing season.
  3. Durable Construction & Dump Feature: It has a heavy-duty steel frame, poly tub (no rust), and pneumatic tires for rough terrain. The quick-release dump mechanism lets you unload heavy loads without shoveling—a huge time saver.

Which Should You Buy?

Buy Mower A if… Your primary, immediate need is to cut a small to medium-sized lawn (under ½ acre) on a tight budget. You are willing to risk low reliability (only 2 reviews) for a very low price. You need a self-propelled machine for hills, and you don’t already own a lawn tractor or ATV to pull a cart. This is a mower for the person who only needs to cut grass.

Buy Mower B if… You already own a lawn mower (push, self-propelled, or riding) and need to move heavy materials around your property. You are a gardener, landscaper, or homeowner with flower beds, a vegetable garden, or trees. The Gorilla Cart will save you hundreds of trips carrying buckets of soil, mulch, or rocks. It is also the smarter purchase if you plan to buy a riding mower later, as it will be a perfect trailer.

Buy Neither if… You need to cut grass but have a large lawn (over ½ acre) or want a reliable machine. The mower’s low price and lack of reviews suggest it may be a low-quality, short-lived product. Instead, consider a well-reviewed self-propelled mower from Honda, Toro, or EGO (battery). If you need to haul and cut grass, buy a decent mower first, then add the Gorilla Cart later for $129.99.
