EGO Power+ 15-Inch 56V Commercial String Trimmer — Carbon-Fiber Shaft & Brushless Motor

The EGO Power+ STX3800 is a 15-inch, 56-volt commercial-grade cordless string trimmer with a carbon-fiber shaft, brushless motor, and lifetime-shaft warranty (battery and charger sold separately).

Built for landscapers and serious homeowners who want gas-level performance without the noise and fumes, this Commercial Series trimmer pairs a high-efficiency brushless motor with a carbon fiber shaft that’s stronger than standard metal shafts and backed by a lifetime warranty. Its 15-inch cutting swath and professional .095" cutting line improve clearing speed, while weather-resistant construction helps it stand up to demanding jobsite conditions. Note: the trimmer is compatible with EGO Commercial Backpack batteries (BAX1501) and the Backpack Link (BXH1001); battery and charger are not included.

How much cutting power and coverage does the STX3800 provide?

The STX3800 runs at up to 5,700 RPM and delivers a 15-inch cutting swath, giving you fast clearing for tall grass and thick weeds. The professional .095" line offers more bite and durability than consumer-grade line.

• Maximum speed: 5,700 RPM for efficient cutting
• Cutting swath: 15 inches for wider passes
• Line diameter: .095" professional cutting line for tougher vegetation

Will it hold up on commercial jobs and in wet conditions?

This model is engineered for commercial use with weather-resistant construction and a carbon fiber shaft that resists twisting and fatigue better than ordinary shafts. EGO backs the carbon fiber shaft with a lifetime warranty, offering long-term reliability on the jobsite.

• Carbon fiber shaft with lifetime warranty for long service life
• Weather-resistant housing suitable for damp conditions
• 2-year commercial warranty covering defects and workmanship

How user-friendly is it for long shifts and tight spaces?

The brushless motor reduces vibration and extends runtime, making the trimmer quieter and easier to handle during extended use. Its balanced, lightweight design and bump-feed head simplify trimming around beds, fences, and walkways.

• High-efficiency brushless motor for lower vibration and longer runtime
• Bump-feed head for quick line advancement without tools
• Balanced, lightweight layout to reduce operator fatigue

What batteries and accessories work with this trimmer?

The STX3800 is part of EGO's Commercial Backpack Series and works with the BAX1501 backpack battery and BXH1001 Backpack Link for extended run time. Because the battery and charger are sold separately, you can match power capacity to your workload or use existing EGO Commercial batteries.

• Compatible with EGO Commercial Backpack Battery (BAX1501)
• Works with Backpack Link (BXH1001) for secure connection
• Battery and charger not included—choose capacity based on runtime needs
