Worx Wg163 vs Wg170 of 2026 Spool & Tool Guide

Mastering Crisp Lawn Edges and Clean Borders

Tangled trimmer line and stubborn bump feed heads can turn a quick weekend yard cleanup into an exhausting chore. When grass grows thick along stone walkways and garden fences, having reliable cutting line advance and balanced tool weight makes all the difference. Evaluating the worx wg163 vs wg170 cordless platforms highlights how subtle differences in shaft design, feed mechanisms, and battery weight balance impact everyday lawn maintenance. Both 20V yard tools utilize a compact 0.065-inch trimmer line diameter to slice cleanly through turf without placing heavy strain on the electric motor.

Motor efficiency and rapid spool swapping keep your trimming moving without tedious downtime. Operators managing tight residential fences or pairing their routine with tools like an electric saw to cut fence posts benefit from quick-loading pre-wound trimmer spools and sturdy replacement spool caps. Based on product specifications and user feedback, both models handle routine perimeter detailing smoothly, but selecting between the push-button Command Feed setup of the WG163 and the multi-angle versatility of the WG170 comes down to your personal edging preferences and yard layout.

Frequently Asked Questions

What is the primary difference in the worx wg163 vs wg170 comparison?

The primary difference lies in shaft adjustability and head articulation. The WG163 features a tilting head with dual-position inline wheels for basic lawn edging, while the WG170 offers an upgraded rotating handle, multi-position head pivoting, and a 3-in-1 design that functions as a trimmer, edger, and mini-mower. Both tools share the 20V battery ecosystem and deliver reliable light-duty grass trimming around residential yards.

Do the Worx WG163 and WG170 share the same spool parts?

Yes, both models use the identical WA0010 and WA0004 factory spool profiles with the WA6531 cap cover. Each replacement spool comes pre-wound with 10 feet of 0.065-inch trimmer line designed with an aerodynamic shape to reduce drag on the motor. Homeowners can interchange these spools seamlessly between either trimmer without fitment issues or line jamming.

Can you use thicker 0.080-inch string on the Worx Wg163 Vs Wg170 in 2026?

No, you should not install line thicker than 0.065 inches on these trimmers. The auto-feed eyelets and spool chambers are calibrated strictly for 0.065-inch nylon line to ensure smooth line advancement. Installing thicker line can cause internal feed jams, overheat the electric motor, and damage the spool housing. For trimming heavy woody growth that string cannot handle, property managers often turn to a dedicated pruning saw for gardeners instead.

How does Command Feed operate on these cordless string trimmers?

Command Feed advances line electronically at the press of a trigger button rather than requiring traditional bumping against the turf. Tapping the handle-mounted button releases a fresh segment of aerodynamic nylon line instantly while the motor is spinning. This mechanism preserves spool caps from rough impact wear along concrete curbs and brick borders.

How long does the 20V PowerShare battery run during yard trimming?

Runtime typically averages between 15 and 30 minutes per charge depending on battery amp-hour capacity and grass density. A standard 2.0 Ah pack delivers ample power for neat edging along typical suburban driveways, while thicker damp weeds consume charge more quickly. Keeping a spare 20V lithium-ion battery on hand ensures continuous trimming across larger property borders without waiting for recharges.

Are blade heads compatible with both trimmer models?

Yes, specialized replacement trimmer heads with flexible polyamide nylon blades fit both the WG163 and WG170 brackets. These blade assemblies clip directly onto the shaft housing to slice cleanly through ordinary grass without unspooling line. However, operators should avoid running nylon blades against chain-link fences or brick foundations to prevent premature chipping.
