Self Propelled Lawn Mower 20-Inch with 60L Grass Bag - 173cc Engine Gas Push Lawn Mower for Hills 3-in-1 Mulch Bag Side-Discharge Rear Wheel Drive for Uneven Yards​​ Lawn Care (173CC) Review

Overview

The Grass 173CC Self-Propelled Lawn Mower is a budget-friendly gas mower designed for homeowners with uneven, hilly yards who need rear-wheel drive traction without spending over $500. At $194.99, it undercuts most self-propelled competitors by a wide margin, offering a 20-inch cutting deck, a 60-liter grass bag, and 3-in-1 capability (mulch, bag, side-discharge). This mower is best for small to medium lawns (up to about 1/3 acre) where hills and bumpy terrain make a push mower a workout.

Who Should Buy This

• Homeowners with sloped or uneven lawns — The rear-wheel drive system provides solid traction on hills, so you’re not fighting the mower uphill or sliding sideways on bumpy ground.
• Budget-conscious buyers who want self-propelled — If you’re tired of pushing a manual mower but can’t justify $400+ for a Honda or Toro, this Grass mower delivers the feature set at half the price.
• DIYers who don’t mind basic assembly and maintenance — This mower comes mostly assembled but requires oil, fuel, and a few bolt-tightening steps. If you’re comfortable with a wrench and a funnel, you’ll save serious cash.
• Homeowners with smaller yards (under 1/3 acre) — The 20-inch deck is nimble for gates and tight spaces, but the 173cc engine isn’t built for marathon mowing sessions on larger properties.

Key Features Breakdown

173cc Gas Engine — This is a basic overhead-valve engine, likely a generic Chinese clone of a Honda GXV. It’s adequate for cutting grass up to about 4 inches tall, but don’t expect it to power through thick, wet, or overgrown lawns. It starts reliably with choke and primer bulb, but may bog down in heavy growth. Best for weekly mowing on maintained turf.

20-Inch Cutting Deck — A 20-inch deck is narrower than the standard 21-22 inch decks on most self-propelled mowers. That means more passes to cover your lawn, but it also means better maneuverability in flower beds, around trees, and through narrow gates. If your yard is full of obstacles, this is a plus.

Rear-Wheel Drive (RWD) Self-Propulsion — RWD is ideal for hills because it pushes the mower forward from behind, giving you better traction on slopes compared to front-wheel drive. The drive engages via a squeeze lever on the handle. Note: The speed is fixed (no variable speed control), so you’ll walk at one pace.

60-Liter Grass Bag — That’s about a 15-gallon capacity, which is larger than many budget mowers (typically 50-55 liters). You’ll make fewer trips to the compost pile. The bag hangs off the rear and is easy to lift and empty, though it can be awkward to maneuver when full.

3-in-1 Capability (Mulch, Bag, Side-Discharge) — A lever on the deck lets you switch between bagging and mulching without tools. Side-discharge requires a separate chute (included). Mulching performance is average—it chops clippings finely enough for healthy lawns, but don’t expect the clean cut of a high-end mulching mower.

Single-Speed Drive — There’s no variable speed control. You get one walking pace, which is fine for flat ground but can feel too fast on steep hills or too slow on straightaways. It’s a trade-off for the low price.

Pros

1. Exceptional value for a self-propelled mower — At under $200, you’re getting RWD, a large bag, and 3-in-1 capability. Most self-propelled mowers start at $300+.
2. Rear-wheel drive handles hills well — On moderate slopes, the RWD system keeps you moving forward without wheel spin. It’s a genuine help for hilly yards.
3. Large 60-liter bag reduces trips — You can mow a good portion of a 1/4-acre lawn before needing to empty, especially if you’re mulching.
4. Compact 20-inch deck for tight spaces — If your yard has narrow gates, trees, or landscaping beds, the smaller deck is easier to maneuver than a 22-inch model.
5. Simple, no-frills operation — No cables to adjust, no variable speed to fiddle with. Squeeze the lever and go. It’s refreshingly straightforward.
6. Light enough to lift — At around 65 pounds, it’s manageable for loading into a truck or carrying over obstacles, unlike heavier 80+ lb mowers.

Cons

1. Engine lacks power for tough conditions — The 173cc engine struggles in thick, wet, or tall grass. You’ll need to take smaller passes and mow frequently. It’s not a “let it go two weeks and catch up” mower.
2. Fixed-speed drive is limiting — On steep hills, the single speed can feel too fast, making it hard to control. On flat ground, it may feel too slow. No customization here.
3. Build quality is budget-tier — The plastic wheels, thin steel deck, and basic handle feel less durable than premium brands. It’ll last a few seasons with care, but don’t expect a 10-year mower.
4. Assembly can be frustrating — The handle, cables, and bag require some fiddling. Instructions are minimal, and the throttle cable may need adjustment. Budget 30-45 minutes for setup.

Bottom Line

The Grass 173CC Self-Propelled Mower is a solid entry-level choice for homeowners with small, hilly lawns who want self-propelled convenience on a tight budget. It won’t win any awards for power or refinement, but the rear-wheel drive, large bag, and sub-$200 price make it a genuine value for occasional mowing on moderate slopes. If you have a flat, well-maintained lawn under 1/4 acre and don’t mind a fixed-speed drive, this mower will get the job done without breaking the bank. However, if you mow thick grass, have a large yard, or want premium features like variable speed and a stronger engine, spend more on a Honda or Toro. For the price, this is a fair deal—just keep your expectations in check.

Frequently Asked Questions

Q: Does this mower come with oil and fuel?
