RB 17ft Cordless String Trimmer - Powerful 40V Brushless Performance

In this review the RB 17' Cordless String Trimmer earns its place as a battery-powered alternative to small gas trimmers for homeowners who need real cutting power without fumes or constant maintenance. The single biggest reason to buy is its brushless 40V motor, which delivers gas-like performance and a top speed up to 5800 RPM while remaining lightweight and easy to handle. For regular lawn upkeep, edging and tackling stubborn weeds, this unit finds a strong balance of runtime, power and convenience.

Key Features

• Brushless motor: Provides more power than a 32cc gas trimmer in many tasks, letting users cut through thick grass and weeds with confidence.
• 17' cutting swath: Covers more ground per pass so trimming goes faster and you spend less time on repetitive passes.
• Dual-feed 0.095' line: Uses professional spiral twist line for efficient cutting and fast re-spooling when the head needs fresh line.
• 2-in-1 trimmer and edger: The head rotates 90 degrees to convert to an edger quickly, saving storage space and the need for a separate tool.
• Lightweight, adjustable design: At about 6.6 lbs with a telescopic shaft and adjustable handle, it is easier to maneuver for longer periods with less fatigue.
• Battery runtime and fast charging: The included 4.0Ah battery provides up to about 45 minutes of runtime and the fast charger gets you back to work more quickly.

Who It's For

The RB 17' Cordless String Trimmer is well suited to homeowners with small to medium yards who want gas-level cutting performance without the smells, maintenance and vibration of a gas engine. It is especially useful for people who value light weight and easy handling for edging sidewalks, trimming around gardens and cutting back tougher weeds.

Those with very large properties that require continuous multi-hour operation or professional landscapers who need a full fleet of high-hour equipment may prefer a larger battery platform or commercial gas units. Users who need specialized attachments beyond trimming and edging should also consider a different system.
