Power & Performance
The WG779 runs on WORX's 40V Power Share platform, drawing from two included 4.0Ah batteries. This power level is well-matched to its 14-inch deck and the light-duty cutting it's designed for , handling typical residential grass types like Kentucky bluegrass, fescue, and St.
Augustine with ease on a regular mowing schedule. It won't overpower dense, overgrown lawns, so keeping up with a weekly mowing routine is key to getting a strong option for results.
Cutting System
The 14-inch polymer rotary deck is lighter than steel alternatives and completely rust-proof, which matters for a mower stored in damp conditions. Six cutting height positions span 1.5 to 3.5 inches via a single central adjuster, making height changes fast and consistent across all four wheels.
The 2-in-1 system lets you mulch clippings back into the lawn or collect them in the rear 0.85-bushel bag , a practical option set for a compact mower.
Drive & Handling
This is a manual push mower, so all forward motion comes from the operator. At 29.1 lbs, it's light enough that most users won't notice the absence of self-propulsion on flat ground.
The 7-inch wheels front and rear keep it rolling smoothly on even surfaces, and the adjustable, foldable handle accommodates different user heights while collapsing down for storage. Tight spaces and narrow garden gates are where the 14-inch deck genuinely shines over wider alternatives.
Battery / Fuel
With two 40V 4.0Ah batteries included, the WG779 offers enough runtime to handle the full 5,445 sq ft coverage area in one session, swapping batteries mid-mow if needed. Charge time varies, but having a spare battery eliminates downtime.
The biggest maintenance advantage over gas is the near-zero upkeep , no oil changes, spark plug replacements, air filter cleaning, or stabilizer treatments. Push the button and it starts, every time.
Who Is This Mower For?
Ideal For
- ✓ Homeowners with yards up to 5,445 sq ft who want a quick, quiet mow without dealing with gas, oil, or pull cords
- ✓ Apartment or townhouse residents with small lawns or courtyard grass who need compact storage , the foldable handle fits easily in tight sheds or closets
- ✓ Eco-conscious users who want zero direct emissions and quieter operation than gas-powered models
- ✓ Older adults or users with limited upper-body strength who benefit from the 29.1 lb lightweight design and push-button start
Not Ideal For
- ✕ Owners of medium to large yards over 5,500 sq ft , the 14-inch deck means significantly more passes and longer mowing time
- ✕ Properties with steep slopes or hilly terrain where a self-propelled drive system would provide much better control
- ✕ Users who frequently let grass grow tall and thick, where the smaller deck and bag capacity would become a real bottleneck
The WG779 ships largely pre-assembled and requires no tools to complete setup , customers consistently report being mow-ready within minutes of opening the box. Handle unfolding, battery installation, and bag attachment are all tool-free.
Charge both batteries fully before the first use to calibrate capacity and maximize initial runtime
Adjust the handle height to your own before the first mow , the multi-position handle makes a noticeable difference in comfort over longer sessions

FAQ
How long do the batteries last on a single charge with the WORX WG779?

Is the WORX WG779 good for thick or overgrown grass?
The WG779 performs best on regularly maintained lawns mowed on a weekly schedule. Its 40V power and 14-inch deck are optimized for light-duty residential cutting rather than tackling thick, overgrown growth.

Does the WORX WG779 mulch clippings?
Yes , the WG779 is a 2-in-1 mower that supports both mulching and rear bagging. Mulching mode chops clippings finely and returns them to the lawn as a natural fertilizer.
The included rear bag holds 0.85 bushels when you prefer a cleaner finish.
How heavy is the WORX WG779 and is it easy to push?
