The WORX Nitro WG751.3 is a steel-deck cordless push mower powered by two 20V Power Share PRO batteries working together as a 40V Max system. It has a 20-inch deck, a 19-inch cutting swath, seven height settings, and all three common clipping modes. The kit normally includes two 4.0Ah batteries and a dual-port charger.
This model fills the gap between compact plastic-deck mowers and heavier self-propelled machines. It offers a sturdy deck and brushless motor without the cost or complexity of a drive system. WORX currently labels it “Coming Soon” on its U.S. site, so availability and seller bundle details need checking.

20-inch deck versus 19-inch cut
Retail titles call the WG751.3 a 20-inch mower because that is the deck size. WORX lists the actual blade cutting width as 19 inches. Use 19 inches when estimating passes or comparing it with another mower.
The stamped-steel deck is heavier than a molded composite deck but should feel more substantial around normal bumps and uneven ground. Steel can rust if packed with wet clippings and stored damp, so clean it after use and keep it indoors.
Power Share batteries explained
The mower needs two 20V batteries installed at the same time. Together they supply the required operating voltage; they are not two sequential battery banks. WORX recommends using two batteries with the same amp-hour rating and similar state of charge. If the packs differ, performance is limited by the weaker battery.
The included Power Share PRO packs use additional cell management and heat protection, but standard compatible Power Share lithium-ion batteries can also work. Higher-capacity matched pairs extend runtime. Because two packs are required, the cost of expanding runtime is the cost of a pair rather than one battery.
WORX does not publish a simple acreage or runtime figure on the current WG751.3 product page. That is a reason to avoid treating seller claims as guaranteed. Grass height, density, moisture, cutting height, mulching load, battery age, and temperature all change how long the mower runs.
Best yard size
The WG751.3 is best for a small to medium lawn where a 19-inch blade provides reasonable coverage and the user is comfortable pushing about 54 pounds. A maintained lawn around one-quarter acre is a sensible starting point for the included 4.0Ah pair. Larger open lawns may justify a second matched battery pair or a mower sold with higher-capacity packs.
Flat ground is the easiest fit. The large rear wheels help over uneven turf, but there is no self-propelled drive. On sustained slopes, the extra weight of the steel deck may become tiring.
Cutting height and clipping choices
The 1.5-to-4.25-inch range is unusually broad for this class. The higher settings suit tall-cut cool-season lawns, while the lower settings cover many warm-season grasses. One lever changes all four wheels, saving time compared with individual wheel adjustments.
NutriCut is WORX’s name for its dual-edge mulching blade design. Mulching works best with dry grass and frequent mowing. The 1.4-bushel rear bag keeps clippings contained, and the included side chute handles heavier growth with fewer clogs. Switching among the three modes requires the correct plug, bag, or chute to be installed with the mower off and both batteries removed.
Our research method
Our reviews are research-based. We compare official specifications, manuals, warranty terms, owner feedback patterns, current availability, and competing products. Unless we specifically say otherwise, the product has not been personally tested by our editorial team.
Handling and storage
The WG751.3 is not as light as a 16-inch plastic-deck mower, but it remains easier to maneuver than many self-propelled 21-inch models. The handle folds completely, allowing compact upright storage in a dry garage or shed. WORX advises against outdoor storage.
A charge-level indicator provides a quick battery check. Before mowing, verify that both packs are fully seated and similarly charged. Remove them before clearing a clog, changing the WA0025 blade, or cleaning beneath the deck.
WG751.3 versus Greenworks LME474
The WORX has a steel deck, brushless motor, taller 4.25-inch maximum cut, and side discharge. The Greenworks LME474 uses two 24V batteries, has a molded 20-inch deck, and promotes up to 45 minutes of runtime. Both are push mowers with two-battery systems, so platform ownership can decide the better value.
For a lighter small-yard option, see the Greenworks 25322 review. Buyers who want propulsion and more cutting power can compare the EGO LM2150SP.

Frequently asked questions
Is the WG751.3 self-propelled?
No. It is a manual-push mower.
Does it use one or two batteries?
It requires two compatible 20V Power Share batteries at the same time. Use a matched, equally charged pair.
Is the cutting width really 20 inches?
The steel deck is 20 inches wide; WORX lists the blade cutting width as 19 inches.
Can it side discharge?
Yes. The kit includes a side-discharge chute along with the bag and mulch plug.
Can it be stored upright?
Yes. The handle collapses for stand-up storage. Keep the mower in a dry indoor location and follow the manual.
Verdict
The WORX Nitro WG751.3 is a well-rounded push mower for buyers who want a steel deck, brushless motor, broad height range, and three clipping modes. It is best on a flat small-to-medium lawn. Confirm the exact battery bundle and current availability, and choose a self-propelled model if hills make a 54-pound push mower impractical.
