Overview

The WORX Nitro 16" Cordless Lawn Mower (WG737) is a lightweight, battery-powered push mower designed for small to medium lawns up to 1/4 acre. It combines a brushless motor with two 20V Power Share batteries, offering a gas-free, low-maintenance alternative for homeowners who want a nimble machine that’s easy to store and maneuver. If you’re tired of wrestling with extension cords or priming a finicky carburetor, this mower aims to simplify your Saturday morning routine.

Who Should Buy This

• Homeowners with 1/4 acre or smaller lawns – The 16-inch cutting deck and dual-battery runtime are a perfect match for compact yards. You’ll likely finish your whole lawn on a single charge if you mow regularly.
• Buyers who hate gas cans and engine maintenance – No oil changes, no stale fuel, no pull cords. This mower is for anyone who wants to grab, go, and be done.
• People with narrow gates or tight storage spaces – At 35 pounds and with foldable handles, this mower tucks into a shed corner or closet without hogging floor space.
• Seniors or lighter users – The lightweight build and simple push operation make it easy for anyone to handle, even on mild slopes.

Key Features Breakdown

Battery System & Runtime
The WORX uses two 20V 4.0Ah Power Share batteries in series. In real-world conditions on a typical 1/4-acre lawn (about 5,000–6,000 square feet of grass), you’ll get roughly 30–40 minutes of runtime. That’s enough for most small yards, but if your grass is thick or damp, expect less. The included rapid charger refills both batteries in about 2 hours. The Power Share platform is a big plus—compatible with over 100 WORX tools.

Brushless Motor
Brushless motors are more efficient and durable than brushed ones. Here, it means more torque for cutting thicker grass and longer battery life per charge. You’ll notice it doesn’t bog down as easily as cheaper cordless mowers when the grass is a bit overgrown.

16-Inch Cutting Deck
This is a narrow deck—great for tight spaces and trimming around flower beds, but it means more passes on open lawn. For a 1/4-acre lot, you’ll spend about 20–25 minutes mowing. If your yard is wide open, a 20-inch mower might save you time.

2-in-1 Function (Mulch & Rear Bag)
You can switch between mulching and bagging without tools. The mulch plug is effective for fine clippings, and the 11-gallon rear bag is easy to empty. No side discharge option, which is fine for small lawns but worth noting if you prefer that.

Single-Lever Height Adjustment
One lever adjusts all four wheels together across 6 positions (1.5 to 3.75 inches). It’s simple and fast—ideal for changing between seasons or grass types.

Lightweight Design (35 lbs)
At 35 pounds with batteries, this is one of the lightest cordless mowers on the market. You can lift it into a truck bed or carry it up a few steps without strain.

Pros

1. Truly lightweight – At 35 pounds, it’s easy to push, lift, and maneuver, especially on uneven ground.
2. Excellent battery compatibility – The Power Share system means you can swap batteries with your WORX trimmer or blower.
3. Quiet operation – At around 85 decibels, you can mow early without waking the neighbors or needing earplugs.
4. No maintenance hassle – No oil, no gas, no spark plugs. Just charge and mow.
5. Compact storage – Handles fold down quickly, and the mower stands upright, taking up minimal space.
6. Good cut quality – The brushless motor gives consistent blade speed, and the mulching performance is solid for a 16-inch mower.

Cons

1. Limited runtime on thick grass – If your lawn is dense, wet, or tall, you may only get 20–25 minutes per charge. You’ll need to plan your mowing or buy extra batteries.
2. Small deck size – 16 inches is narrow. For anything over 1/4 acre, you’ll be making extra passes and draining batteries faster.
3. No self-propelled option – This is a pure push mower. On gentle slopes it’s fine, but hilly yards will have you working harder.
4. Bag capacity is modest – The 11-gallon bag fills quickly, especially in spring growth. You’ll be stopping to empty it frequently on larger lawns.

Bottom Line

The WORX Nitro 16" is a solid choice if your lawn is small and you value lightweight simplicity over raw power. It won’t replace a gas mower for big yards or tough conditions, but for a 1/4-acre suburban lot, it delivers reliable, quiet, low-fuss mowing. The battery compatibility with other WORX tools is a real bonus. If you’re okay with a narrow deck and don’t mind a few extra passes, this mower is a great entry into cordless lawn care. I’d recommend it confidently to anyone with a small yard who wants to ditch gas and cords.

Frequently Asked Questions

Q: Can I use just one battery if the other dies?
A: No—the mower requires both batteries to run. They work in series to provide 40V of power. If one battery dies, the mower stops. You can buy additional 20V batteries from WORX to have spares ready.

Q: How long do the batteries last on a full charge?
A: In normal conditions with dry, short grass, expect about 30–40 minutes of runtime. On thick or damp grass, that drops to 20–25 minutes. The included charger takes about 2 hours to fully charge both batteries.

Q: Does this mower work on slopes?
A: It handles gentle slopes fine, but it’s not self-propelled, so you’ll need to push uphill. The lightweight design helps on mild inclines, but steep hills will be a workout. For hilly yards, look for a self-propelled model.
