The included 20V 4.0 Ah PowerShare battery offers solid runtime and cooling to avoid throttling, while the motor gives more power and longer life than WORX brushed models. Controls and telescoping shaft make mode changes easy, though heavier battery weight shifts balance — keep reading for full performance and comparisons.
Some Key Takeaways
- Brushless motor delivers ~25% more power and ~50% longer runtime than WORX brushed units, improving cutting performance and efficiency.
- Includes POWERShare PRO 20V 4.0 Ah battery with cooling design for ~30% longer runtime and reduced thermal throttling.
- True 3‑in‑1 design (trimmer, edger, mini‑mower) switches quickly via telescoping shaft and pivoting head for versatile yard work.
- Handles common weeds, thicker patches, and crisp edging with steady line feed and predictable grass discharge.
- Best for small-to-medium yards and PowerShare users; not ideal for large properties requiring wider decks or higher-voltage power.
How the WORX Nitro WG173 Works and What’s in the Box
Although it’s battery-powered and cordless, the WORX Nitro WG173 delivers mower-like coverage by combining a brushless motor, dual-line 0.065″ head, and a 13″ cutting diameter to trim, edge, or roll as a mini mower. You’ll find the unit, PowerShare PRO 20V 4.0 Ah battery, charger, wheels, and basic hardware in the box. Follow an assembly checklist to fit handles, attach wheels, and confirm battery seating. Controls include mode switch, push-button Command Feed, telescoping shaft, and pivoting head. Observe safety precautions: wear eye protection, remove debris, and disconnect battery before maintenance to protect yourself and others. The WORX Nitro WG173 is a strong choice for homeowners who want an efficient, battery string trimmer with dedicated battery compatibility.
Real-World Performance: Trimming, Edging, and Mini-Mowing Tests
Now that the WG173 is assembled and you know the controls, let’s assess how it performs in everyday yard tasks. You’ll find trimming delivers steady line consistency across edges and open turf, handling common weeds and thicker patches without frequent snags. As an edger, the wheeled setup produces crisp borders and predictable grass discharge direction, so cleanup feels straightforward. In mini-mower mode the coverage is efficient for small patches; maneuverability and wheel traction keep passes even. You’ll appreciate predictable behavior, quick mode changes, and community-minded design that helps you maintain shared spaces with confidence. This model complements other homeowner-focused outdoor gear, especially when used alongside backpack blowers for efficient yard care.
Power, Runtime, and Motor Tech That Matter (Battery, Brushless Motor)
Expect solid real-world power and runtime from the WG173 thanks to its brushless motor and included Power Share PRO 20V 4.0 Ah battery: the motor delivers about 25% more power and runs roughly 50% longer than WORX’s brushed units, while the 4.0 Ah pack is engineered to run ~30% longer than the older GT battery and stay cooler under load. You’ll notice consistent torque across tasks, and battery cooling design helps prevent thermal throttling during longer jobs. That brushless design boosts motor longevity and efficiency, letting you finish larger sections with fewer battery swaps and predictable performance. It’s a strong option for homeowners who value maintaining beautiful yards without constant recharging.
Usability and Build: Controls, Ergonomics, and Mode Switching
When you pick up the WG173 you’ll notice the controls and layout prioritize straightforward operation: a single trigger for power, a push-button command feed for instant line advancement, and a telescoping, rotating shaft with an adjustable auxiliary handle that lets you dial in reach and balance quickly. You’ll find control placement logical—trigger and feed within easy thumb or finger reach—so switching modes feels intentional. The shaft rotation and pivoting head make shifts between trimmer, edger, and mini-mower efficient. Grip comfort is solid for extended use, though heavier battery weight shifts balance; overall build feels durable and community-minded. The WG173 is a practical choice for homeowners who enjoy well-maintained yards and reliable electric hedge trimmers.
Who Should Buy the WG173 and How It Compares to Alternatives
Who needs the WG173? You should consider it if you want a lightweight, battery-powered 3-in-1 that handles trimming, edging, and light mowing with brushless efficiency and Power Share battery convenience. Best buyers are homeowners with small-to-medium yards who value tool-platform compatibility and low maintenance. You’ll appreciate quick mode changes, push-button line feed, and longer runtime versus older WORX models.

The site also offers a range of cordless mower accessories and related products for homeowners who enjoy their outdoor spaces at home, including replacement parts and batteries like those in the Power Share system.
Some Questions Answered
Is the WG173 Safe to Use in Wet or Rainy Conditions?
No — you shouldn’t use the WG173 in heavy rain or submerged conditions. The tool isn’t advertised with waterproof ratings for continuous wet use; treat it as rainproof maintenance only, meaning brief exposure or light drizzle is tolerable if you dry and inspect it afterward. You’ll protect the battery, motor and electronics by avoiding puddles, storing gear dry, and following manufacturer care. That keeps you and the community safe while extending tool life.
Can I Store the Battery Installed During Long-Term Storage?
No — you shouldn’t store the battery installed long-term. For proper battery maintenance, remove the Power Share PRO battery, charge it to about 40–60%, and store it in a cool, dry place within the recommended storage temperature range. Avoid extreme heat or freezing. Check charge every few months and top up if it drops below recommended levels. This keeps the battery healthy and ready, and helps you feel confident and supported.
Are Replacement Wheels or Handles Sold Separately?
Yes — replacement handles and wheels are sold separately; you’ll need to order parts like replacement handles or wheel upgrades through WORX or authorized retailers. Check compatibility with the WG173 model and the WA0007 part listings where applicable. You’ll want to confirm warranty coverage and return policies before buying. If you’re part of the WORX community, sharing model numbers and photos helps everyone pick the right upgrades.
What Noise Level (dB) Does the WG173 Produce During Use?
There’s no manufacturer spec for measured decibels, so you won’t find an official dB rating; perceived loudness is similar to other 20V brushless trimmers—moderate to loud under load. You’ll notice more noise at full throttle and edging versus light trimming. To quantify it, you should measure with a sound meter while running the WG173 at typical and max RPM; that gives objective measured decibels to compare.
Does the Tool Come With a Local Service or Repair Center Network?
Yes — you’ll have access to local service through WORX’s authorized centers and customer support network. You can contact WORX for warranty repairs, parts, or service referrals; they’ll direct you to nearby authorized centers or provide mail-in options. Check WORX’s website or your retailer for center locations and warranty details. You’ll feel supported knowing repair pathways and authorized local service options exist for the WG173.
