Quick Verdict
Bottom line: The Self-Propelled 170cc Gas Lawn Mower With 4-in-1 Cutting packs a rare feature set into a budget-to-midrange price of $329 — self-propelled drive, a 170cc OHV engine, and four cutting modes. However, its current 3 out of 5 stars from 34 reviews signals real-world reliability trade-offs you should weigh carefully. It’s a strong value on paper for medium-to-large yards, but buyers should be comfortable with a newer, mixed-review brand.
Best for: Budget-conscious homeowners with 1/4 to 1/2 acre yards who want bagging, mulching, and discharge flexibility without premium-brand pricing.
Skip it if: You want a proven long-term reliability record or live in California (not available for sale there).
What This Mower Offers
The Self-Propelled Gas Lawn Mower, 170cc 4-in-1 Mulch/Bag/Side & Rear Discharge, 7-Position Height Adjustment, Foldable Walk-Behind Lawn Mower for Yard & Garden (Yellow) is positioned as a practical, do-it-all machine for homeowners who want gas-powered cutting performance without paying premium-brand prices. Its key question is simple: does this mower offer enough performance and convenience to justify the price, or are the compromises too significant?
At its core is a 170cc OHV 4-cycle engine paired with a self-propelled drive system, designed to deliver reliable cutting performance with runtimes of up to 1.5 hours per tank. The 4-in-1 cutting setup supports mulching, rear bagging, side discharge, and rear discharge — a meaningful advantage at this price, since these modes give you flexibility across seasons and grass conditions.
Wheels are sized at 8 inches front and 10 inches rear, which improves traction and helps the mower roll more smoothly over uneven terrain than a basic push mower. Height adjustment spans 7 positions with a cutting range from 1 inch to 3 inches, and convenience touches include a foldable handle, a large 65L grass bag, and a mostly pre-assembled setup that takes roughly 10 minutes.
Compared with many basic gas mowers in the same price range, the biggest advantage here is feature density. A 4-in-1 system and self-propelled drive are often reserved for more expensive models, so this mower tries to stand out by delivering more versatility per dollar.

Pros & Cons
Pros
- Self-propelled drive cuts down effort on slopes, uneven patches, and dense grass.
- 170cc engine provides practical residential power — better suited to medium and large yards than compact push mowers that bog down in thick growth.
- Four cutting modes add real versatility: mulch to return nutrients, bag for a tidy finish, and side/rear discharge for faster passes in taller grass.
- Seven height settings (1"–3") let you raise the cut in hot weather or drop lower for a cleaner look.
- Large 65L bag means fewer interruptions when bagging on bigger lawns.
- Foldable handle and quick ~10-minute setup make storage and first use painless.
Cons
- Mixed 3/5-star rating from 34 reviews suggests inconsistent real-world reliability.
- Not available for sale in California due to emissions restrictions — a dealbreaker for West Coast buyers.
- Feature-dense budget design means trade-offs in build quality compared with premium brands.
- Cutting height tops out at 3 inches, which may be limiting for cool-season lawns that benefit from a higher summer cut.
Frequently Asked Questions
Is a 170cc engine powerful enough for a large yard?
For most residential lots up to roughly half an acre, yes. A 170cc OHV 4-cycle engine is a solid specification for routine lawn maintenance and is generally better suited than compact push mower engines, which can bog down in thick grass. For very large properties or heavy overgrowth, you’d want to mow more frequently or consider a larger displacement engine.
What does 4-in-1 cutting actually mean?
It means the mower supports four grass-disposal methods: mulching (finely clipping grass back into the lawn to return nutrients), rear bagging (collecting clippings in the 65L bag), side discharge (ejecting clippings out the side for fast mowing), and rear discharge (ejecting clippings behind the mower, useful when a bag isn’t attached). This flexibility matters because the best mode changes with the season — mulch in spring, bag in fall, discharge in heavy growth.
Why can’t this mower be sold in California?
California enforces strict small-off-road engine (SORE) emissions standards administered by the California Air Resources Board (CARB). Engines must be certified to meet those standards before equipment can be sold in the state. This model is explicitly listed as not available for sale in California, meaning its engine doesn’t carry CARB certification. Buyers elsewhere in the U.S. are unaffected.
How long does the mower run on a full tank?
According to the product description, the engine runs for up to 1.5 hours per tank. Actual runtime will vary with terrain, grass thickness, and how hard the self-propelled drive is working, but for most medium-to-large residential yards that’s enough to finish in one session without refueling.
Is assembly difficult?
No. The mower arrives mostly pre-assembled, and the manufacturer states setup takes about 10 minutes — typically unfolding and securing the handle, adding oil and fuel, and attaching the bag if needed. The foldable handle also makes off-season storage easier in tight garages or sheds.
Should I trust a mower with a 3-star rating?
A 3/5 average from 34 reviews isn’t disqualifying, but it warrants caution. It often indicates the product performs well for some buyers while others hit issues like starting trouble, drive problems, or quality-control inconsistencies. At $329 with this feature set, the value is real — but if long-term dependability is your top priority, comparing it against established brands (as in our Amerisun 170cc review) is worth the time before you buy.
