Kobalt 40V Max 15-in Cordless Straight String Trimmer — Bare Tool, Dual-Line Bump Feed, Lightweight

This straight-shaft trimmer uses Kobalt's 40V Max battery system (battery and charger sold separately) to deliver cordless convenience without gas or cords. With a 15-inch cutting swath and a dual-line bump feed head, the unit balances maneuverability and coverage for routine lawn maintenance. Its slim, straight design improves reach for edging sidewalks and accessing tight spots, while the low weight reduces operator fatigue during longer sessions.

How well does the 15-inch cutting swath handle common yard tasks?

The 15-inch cutting path provides a good compromise between control and coverage: it's wide enough to clear runs quickly yet narrow enough to work precisely along flowerbeds and walkways. For most residential yards, this swath helps finish trimming passes faster than a smaller head without sacrificing accuracy.

• 15-inch cutting diameter for efficient swath per pass
• Dual-line bump feed for quick line advancement
• Suitable for grass, light weeds, and edging around borders

What benefits does the straight shaft design provide?

A straight shaft extends reach and creates a more natural motion for edging and trimming under shrubs or along fences. It improves leverage when cutting along sidewalks or stepping up onto slopes, making precise work easier while keeping the cutting head accessible.

• Straight-shaft geometry for extended reach and better access
• Improved edging posture reduces strain on wrists and back
• Easier trimming around obstacles and tight corners

How does the trimmer perform as part of the Kobalt 40V Max battery ecosystem?

This is a bare tool: batteries and chargers are sold separately. It accepts any Kobalt 40V Max battery, allowing you to reuse existing power packs across compatible tools for cost and convenience. Battery choice determines runtime and power, so select capacity based on yard size and task duration.

• Compatible with all Kobalt 40V Max batteries (sold separately)
• Use higher-capacity batteries for longer runtime on larger yards
• Interchangeable with other Kobalt 40V Max tools to expand your kit

What features help reduce fatigue during longer trimming sessions?

The trimmer’s lightweight construction and balanced straight shaft help minimize user fatigue, especially during extended use. The bump-feed head eliminates fiddly line changes while work continues, and the ergonomic handle layout improves comfort for repeated passes.

• Lightweight build for easier handling and less operator fatigue
• Dual-line bump feed reduces downtime to advance cutting line
• Compact profile for maneuverability in tight or uneven areas
