WORX Nitro Cordless Lawn Mower, 21" Electric Mower for 1/2 Acre, Brushless Push Lawn Mower with 7-Position Height Adjustment, 2 × 5.0 Ah Batteries & Charger Included, WG752 Review

Overview

The WORX Nitro Cordless Lawn Mower (WG752) is a 21-inch, brushless electric push mower designed to tackle up to half an acre of grass without the hassle of gas, oil, or extension cords. It’s built for homeowners who want reliable, low-maintenance cutting power from a brand that’s carved a niche in battery-powered outdoor gear. With two 5.0 Ah batteries and a charger included, this mower aims to deliver the runtime and torque you need for medium-sized lawns, all while keeping noise and fumes to a minimum.

Who Should Buy This

• Homeowners with 1/4 to 1/2 acre lawns – If your yard falls in this sweet spot, the included dual batteries can typically cover the whole job on a single charge, especially with smart mowing habits.
• Ex-gas mower owners tired of maintenance – No more winterizing, mixing oil, or dealing with clogged carburetors. This mower is ready to go with a battery swap and a push of a button.
• Eco-conscious users who want quiet operation – At a fraction of the noise of a gas mower, you can cut early morning or late evening without annoying the neighbors (or your own ears).
• People with uneven or slightly hilly terrain – The 21-inch deck and self-propelled option (this is the push model) handle moderate slopes well, though very steep hills may require a different approach.

Key Features Breakdown

• 21-inch steel deck – A solid, durable cutting platform that’s wide enough to be efficient on open areas but still nimble for navigating flower beds and gates. The steel construction adds weight for stability without being a backbreaker.
• Brushless motor – More efficient and longer-lasting than brushed motors. It delivers consistent torque even in thick grass, and it’s virtually maintenance-free—no brushes to replace.
• Two 5.0 Ah batteries included – This is the real selling point. Most competitors give you one battery; WORX packs two, so you can swap mid-mow without waiting for a recharge. Real-world runtime is about 30–40 minutes per battery in average conditions, covering roughly 1/4 acre per charge.
• 7-position height adjustment – A single lever lets you go from 1.5 to 4 inches. That’s a good range for everything from a close, manicured cut in summer to a taller setting for cooler months or drought stress.
• Single-lever cutting height adjustment – No bending over to adjust each wheel individually. One lever on the deck changes all four wheels simultaneously—fast and convenient.
• 3-in-1 function – Bag, mulch, or side discharge. The mulching plug is included and works well for clipping recycling, though heavy wet grass may require bagging to avoid clumps.
• Push-button start – No pull cords, no prime bulbs. Just press and go. This is a small but significant quality-of-life upgrade.

Pros

1. True cordless freedom with no gas mess – The dual-battery system means you’re rarely stuck mid-lawn. Swap batteries in seconds, and you’re back to cutting.
2. Great cut quality for an electric mower – The brushless motor and sharp blade produce clean, even cuts—comparable to a mid-range gas mower in typical conditions.
3. Easy to store and transport – The handles fold down quickly, and the mower stands upright. It takes up less than half the floor space of a typical gas mower.
4. Quiet enough for early morning jobs – At around 80 dB, it’s roughly as loud as a vacuum cleaner. You can mow without earplugs and still have a conversation.
5. Solid build quality for the price – The steel deck feels substantial, and the plastic components are thick and well-molded. It doesn’t rattle or flex like some budget electrics.
6. Batteries work with other WORX tools – If you already own WORX 20V tools (trimmers, blowers, saws), these batteries are cross-compatible, reducing your overall battery investment.

Cons

1. Not truly self-propelled – This is a push mower. If your lawn has steep slopes or you have mobility issues, you’ll want the self-propelled version (WG753). This model requires muscle on inclines.
2. Batteries can run low on thick, wet grass – In dense, damp conditions, runtime drops to about 25–30 minutes per battery. If your half-acre is lush and damp, you may need a third battery or to mow more frequently.
3. Bag capacity is just okay – The 1.5-bushel bag fills quickly, especially when mulching. You’ll stop to empty it more often than with a larger gas mower bag.
4. No headlight – Not a dealbreaker for most, but if you mow in the evening, you’ll need to rely on ambient light or a separate work light.

Bottom Line

The WORX Nitro Cordless Lawn Mower is a strong contender for anyone with a quarter- to half-acre lawn who wants to ditch gas without sacrificing performance. The dual-battery setup is a genuine advantage over single-battery competitors, and the brushless motor delivers reliable power for most conditions. It’s not perfect—the push-only design limits its appeal on steep terrain, and the bag is on the small side—but for the price, it’s one of the best cordless values on the market. I recommend it confidently for homeowners who prioritize ease of use, low maintenance, and quiet operation over raw power.

Frequently Asked Questions

Q: How long does it take to charge the batteries? A: Each 5.0 Ah battery takes about 2.5 hours to fully charge with the included charger. Plan to charge both batteries overnight or during a workday if you mow frequently.

Q: Can I use this mower on a slope? A: Yes, but with limits. It handles gentle to moderate slopes (up to about 15 degrees) fine. On steeper hills, the push-only design means you’ll work harder, and the batteries may drain faster due to increased load. For very steep yards, consider the self-propelled version.

Q: Does it come with a mulching plug, or do I need to buy one separately? A: It includes a mulching plug in the box. You can switch between bagging, mulching, and side discharge without buying any extra parts. Just remove the bag and insert the plug for mulching.
