131cc Foldable Gas Lawn Mower, Self-Propelled Rear-Wheel Drive, 18 Inch Cutting Width, 50L Grass Bag, 3-in-1 Mulching/Side Discharge/Rear-Bagging, Lightweight Push-Button Start Mower Review

Overview

The Foldable 131cc Gas Lawn Mower is a budget-friendly, lightweight self-propelled mower designed for homeowners with small to medium lawns (up to ¼ acre) who want gas power without the bulk or hassle of traditional machines. Its standout feature is a foldable frame and push-button start, making it one of the most portable and user-friendly gas mowers under $150 on the market.

Who Should Buy This

1. Homeowners with small, flat lawns (¼ acre or less)
The 18-inch cutting deck is narrow enough to maneuver around flower beds and fences, yet still covers ground quickly for its size. If you’re tired of wrestling a heavy 22-inch mower through tight spaces, this is your machine.

2. Renters or those with limited storage
The folding frame collapses to roughly half its height, meaning it can stand upright in a corner of a garage or even a large closet. This is a game-changer for apartment dwellers with a small yard or anyone who hates dedicating floor space to a mower.

3. Gas-first buyers who hate pull-cords
The push-button start eliminates the arm-tiring yanking common on cheaper gas engines. If you’ve got a bad shoulder or just want the convenience of a turn-key experience without going battery-electric, this mower delivers.

4. Budget-conscious shoppers who want self-propelled
At $112.97, this is one of the cheapest rear-wheel-drive self-propelled gas mowers available. You’re getting a feature normally found on $250+ models for a fraction of the cost.

Key Features Breakdown

131cc Engine
This single-cylinder 4-stroke engine provides enough torque for typical grass up to 4-5 inches tall. It’s not a powerhouse for thick, wet St. Augustine or overgrown fields, but for standard fescue or Bermuda, it cuts cleanly. The engine is air-cooled and runs on regular unleaded gas—no mixing oil.

Self-Propelled Rear-Wheel Drive
Rear-wheel drive gives better traction on slopes and uneven ground than front-wheel drive. The drive is variable-speed via a squeeze lever on the handlebar. It’s not continuously variable, but it offers enough control to match your walking pace.

18-Inch Cutting Width
This is the sweet spot for small yards. It’s wide enough to finish a 2,000 sq ft lawn in about 20 minutes, yet narrow enough to fit through standard garden gates. The cutting height adjusts via a single lever (typically 1-3 inches range), which is convenient for quick changes between seasons.

50L Grass Bag
The fabric bag holds about 1.3 bushels of clippings. For a typical weekly cut on a small lawn, you’ll empty it once or twice. It’s not huge, but it’s adequate for the deck size. The bag attaches and detaches with a simple hook system.

3-in-1 Mulching/Side Discharge/Rear-Bagging
You get a mulch plug (for leaving fine clippings on the lawn), a side-discharge chute (for tall grass), and the rear bag. The mulch plug is particularly effective for returning nutrients to the soil—just make sure you’re cutting dry grass.

Push-Button Start
Requires a standard 12V battery (likely included or sold separately—check the listing). Press the button, and the engine fires up instantly. No more flooding the carburetor with 20 pulls.

Foldable Frame
The handlebars fold down and the deck tilts up, reducing the footprint to about 24 x 18 x 18 inches when stored. This is rare in gas mowers at this price point.

Pros

• Incredible value for self-propelled gas: You’re getting a feature (self-propelled) that typically adds $80-100 to a mower’s price. At $112, this is a steal.
• Push-button start is genuinely convenient: No pull-cord fatigue. Even if the battery dies, you can still pull-start (most models have a backup pull cord).
• Folds flat for storage: This is the main reason to buy it over a traditional mower. It fits in a car trunk or closet.
• Light enough to lift: At roughly 45-50 lbs, one person can load it into a truck bed or carry it up a few steps.
• Rear-wheel drive traction: Handles slight inclines better than front-drive competitors like many Craftsman or Yard Machines models.
• 3-in-1 versatility: The mulch plug is effective for lawn health, and the side discharge handles overgrowth without clogging.

Cons

• Small cutting deck limits speed: If you have a ½ acre or more, the 18-inch width will feel painfully slow. This mower is strictly for small properties.
• Build quality is budget-tier: The plastic deck and thin steel handlebars won’t survive abuse. If you hit rocks or roots regularly, expect cracks or bends over time.
• Grass bag capacity is small: The 50L bag fills quickly with thick grass. You’ll be emptying it every 10-15 minutes on a dense lawn.
• Engine may struggle with tall, wet grass: The 131cc engine is adequate for normal conditions but bogs down in heavy, damp clippings. Always cut dry grass.

Bottom Line

The Foldable 131cc Gas Lawn Mower is a no-brainer for anyone with a small, flat lawn who values storage space and hates pull-cords. It’s not a heavy-duty machine—the plastic deck and small engine mean it’s best for weekly maintenance cuts on ¼ acre or less. But for $112.97, you’re getting self-propelled convenience, push-button start, and a foldable design that’s rare at this price. If your lawn is bigger than 5,000 sq ft or you need to tackle thick, unruly grass, look elsewhere. For everyone else—especially renters or first-time homeowners—this is the best value gas mower under $150 right now.

Frequently Asked Questions

Q: Does the push-button start require a battery, and is it included?
A: Yes, the electric start needs a 12V battery (typically a small sealed lead-acid or lithium-ion). Some listings include it; others don’t. Check the product description carefully. If not included, you can buy a compatible battery for about $15-20. The mower also has a backup pull-cord, so you won’t be stranded if the battery dies.

Q: How do you fold it for storage?
A: There’s usually a locking lever or knob on the handlebar. Loosen it, fold the handle down toward the deck, then tip the mower onto its back end so it stands upright. The process takes about 30 seconds. Always turn off the engine and let it cool first.

Q: Can it handle hills?
A: Yes, but with limits
