The American Lawn Mower 1604-16 is a manual reel mower designed for homeowners who value a quiet, eco-friendly approach to lawn care. This 16-inch model with a 5-blade reel is perfect for small to medium-sized lawns, offering a clean, scissor-like cut that is gentler on grass than rotary mowers. It's an ideal choice for those looking to reduce their carbon footprint and enjoy a peaceful mowing experience without the noise and fumes of gas-powered equipment.
Standout features include the adjustable cutting height, which ranges from 1/2 inch to 2 1/2 inches, allowing you to tailor the cut to your grass type and season. The 5-blade reel delivers a precise cut that promotes healthier turf by slicing rather than tearing the grass blades. In real-world use, this mower glides smoothly over level terrain, and the included grass catcher effectively collects clippings, though it may require frequent emptying on larger lawns.
Design and build quality reflect the brand's reputation for durable, functional lawn tools. The red steel frame feels sturdy yet lightweight at only 18 pounds, making it easy to push and maneuver around obstacles. The cushion-grip T-handle provides comfort and control, reducing hand fatigue during longer sessions. Assembly is straightforward, and the mower requires minimal maintenance beyond occasional blade sharpening.
Potential drawbacks include the manual effort required, especially on uneven or slightly overgrown grass. It is not recommended for thick, tall, or wet lawns, as the reel can clog or skip. Additionally, the 16-inch cutting width is narrower than many powered alternatives, meaning more passes to cover the same area. However, these limitations are offset by the mower's affordability, quiet operation, and zero emissions.
Overall, the American Lawn Mower 1604-16 offers excellent value for eco-conscious homeowners with small, flat lawns. It delivers a high-quality cut, easy handling, and a pleasant mowing experience.

If you want an affordable, lightweight, and easy-to-use mower for routine grass maintenance, this model is a strong contender.
Standout features include the dual 20V 4.0Ah batteries that provide up to 40 minutes of runtime, covering up to 5,380 square feet per charge. The brushless motor spins at 3000 RPM, maintaining steady blade speed through typical residential grass. The cutting deck offers six height settings from 1 to 3 inches, allowing you to adjust the cut length precisely.

In terms of design and build quality, the mower weighs only 31 pounds, making it easy to carry and store. The one-button activation and pull-bar start simplify operation.

In real-world use, the 40V battery delivers enough power to cut up to 1/3 acre on a single charge under normal conditions, though heavy or wet grass can reduce runtime.

Overall, the Greenworks 40V 16-inch push lawn mower is an excellent choice for anyone seeking a lightweight, cordless mower for a small to medium lawn. It offers convenience, versatility, and a reliable battery platform. With its 3-year warranty and strong performance for its class, it earns a solid recommendation for eco conscious homeowners.
Choosing the Right Mower for a Bumpy Lawn
Not every mower is built to handle uneven ground. Before you buy, focus on these four criteria. They make the difference between a smooth cut and a frustrating, scalp-filled afternoon.
Wheel Size and Traction
Larger wheels roll over bumps and dips more easily than small ones. Look for mowers with at least 8-inch rear wheels and wide, treaded tires. The Greenworks 60V 21in Push Lawn Mower features oversized 10-inch rear wheels and 8-inch front tires, which give it excellent stability on lumpy ground.
For self-propelled models, rear-wheel drive provides better traction on slopes and uneven terrain. The BILT HARD 21″ Self Propelled Gas Lawn Mower uses rear-wheel drive with a single-speed transmission, making it a solid choice for bumpy yards.
Cutting Height Adjustability
Bumpy lawns need flexible height settings so you can raise the deck over rough patches and lower it on smoother sections. A single-lever adjustment across all four wheels is ideal. The BILT HARD 21″ Self Propelled Gas Lawn Mower offers 8 positions from 1.2 to 3.75 inches, while the LawnMaster LMRM1801 Push Reel Lawn Mower 18-Inch gives you 9 positions between 1.1 and 2.5 inches.
Reel mowers like the American Lawn Mower 1604-16 16″ 5-Blade Reel Mower adjust from 0.5 to 2.5 inches. That range works for many grass types, but you’ll want to keep the blade height higher on uneven ground to avoid scalping.
Self-Propelled vs. Push
On a bumpy lawn, pushing a heavy mower is exhausting. Self-propelled models reduce fatigue and maintain steady speed over rough patches. The BILT HARD 21″ Self Propelled Gas Lawn Mower is a great example, with a foam-wrapped handle that absorbs vibration.
If you prefer a lighter, simpler machine, cordless push mowers like the Cordless Lawn Mower, 17 in Walk Behind Lawn Mower weigh around 14 kg and are easy to maneuver. They’re not self-propelled, but their light weight makes them easier to lift over bumps and roots.
Deck Durability and Weight
Bumpy terrain puts stress on the deck. Steel decks handle impacts better than plastic, but they add weight. The Greenworks 60V 21in Push Lawn Mower features a heavy-duty steel deck that’s both durable and rust-resistant, with an IPX4 waterproof rating for damp grass.
For smaller bumpy yards, a lightweight option like the Cordless Lawn Mower, 13-Inch Walk Behind Lawn at 10 kg is easier to store and carry. Just keep in mind that lighter decks may bounce more on severe bumps, so adjust your pace accordingly.
If you’re torn between a robot mower and a traditional push model, our best robot mower for hilly lawn guide covers slope-climbing robots that can handle some bumpiness. But for truly rough ground, a manual or cordless mower often gives you more control.
Final Thoughts
After reviewing these seven mowers, the Greenworks 60V 21in Push Lawn Mower stands out for large bumpy yards thanks to its big wheels, steel deck, and gas-like power, while the BILT HARD 21″ Self Propelled Gas Lawn Mower is the pick if you prefer self-propelled convenience and don’t mind a gas engine. Both handle uneven ground far better than a typical robot mower, and they give you the control you need to avoid scalping those low spots. Whichever you choose, your bumpy lawn doesn’t have to be a headache.
Frequently Asked Questions
Can a Navimow robot mower handle a bumpy lawn?
Navimow mowers are designed for slopes up to 45% and can navigate mild bumps, but very rough ground with deep dips or exposed roots can confuse their sensors. For those cases, a manual or cordless mower gives you more control. Check out our best robot mower for rolling hills article to see how robotic options compare.
What is the best mower for uneven ground?
The best mower for uneven ground has large wheels, multiple height adjustments, and a durable deck. Self-propelled gas models like the BILT HARD 21″ provide the torque and traction you need, while lightweight cordless mowers like the Greenworks 40V 16in are easier to handle on small bumpy lots.
Are reel mowers good for bumpy lawns?
Reel mowers work on bumpy lawns if the bumps are small and the grass is kept short. The American Lawn Mower 1604-16 and LawnMaster LMRM1801 both offer adjustable cutting heights, but they can scalp on larger dips. They’re best for flat to gently rolling terrain.
Should I get a gas or cordless mower for a bumpy yard?
Gas mowers like the BILT HARD 21″ deliver consistent power and never run out of battery, making them great for large bumpy lawns. Cordless mowers are quieter and lighter, but you need enough battery capacity for the extra effort of rough ground. The Greenworks 60V with a 5.0Ah battery covers up to 1/3 acre in ideal conditions, so plan accordingly in 2026.
