Makita XGT 15-inch String Trimmer GRU01Z — 40V max Brushless, 3‑Speed, Tool‑Only

The Makita GRU01Z is a 40V max XGT brushless 15" cordless string trimmer designed to deliver professional-level power, runtime flexibility, and jobsite durability without gas.

The GRU01Z combines Makita's XGT platform with an outer-rotor brushless motor and intelligent digital controls to give landscapers and property professionals a cordless alternative for heavy trimming tasks. It offers three selectable speed settings, an automatic torque mode that shifts RPMs to balance power and run time, and a Rapid Load Bump & Feed head for fast line changes. Built with Extreme Protection Technology (XPT) and IPX4 weather resistance, this tool is engineered for demanding outdoor use.

How much cutting power and runtime can I expect from this 15" trimmer?

The GRU01Z delivers high torque and sustained power thanks to Makita's outer-rotor brushless motor and digital communication inside the XGT system. Run time varies with battery capacity and speed setting, but with a 40V XGT 4.0Ah battery you can see up to about an hour under typical conditions.

• Three speed options: 3,500 / 5,300 / 6,500 RPM to match turf and load
• Automatic Torque Drive Technology shifts RPM to extend runtime or add power
• 15" cutting swath for faster coverage and fewer passes
• Estimated up to 1 hour with a 4.0Ah XGT battery (battery sold separately)

What features make this trimmer easy to use on busy job sites?

The tool includes user-friendly controls and quick maintenance features that cut downtime. A variable speed trigger and three preset speeds help you dial in performance, while the Rapid Load Bump & Feed head reloads line in three quick steps so you can get back to work fast.

• Variable speed trigger with three distinct speed positions for control
• Reverse rotation clears tangled line without tools
• Rapid Load Bump & Feed head for fast line replacement in seconds
• Adjustable loop handle for ergonomic positioning and reduced fatigue

Is the GRU01Z durable enough for construction and landscape environments?

Yes—Makita engineered the GRU01Z with durability and weather resistance for rough conditions. The XPT system improves resistance to dust and water, and the tool carries an IPX4 rating to withstand splashing and light rain while on site.

• Extreme Protection Technology (XPT) for enhanced dust and water resilience
• IPX4-rated weather-resistant construction for outdoor use
• Robust brushless motor design for long-lasting high-load performance
• Digital XGT communication to maintain consistent power delivery

How does this trimmer fit into the Makita XGT ecosystem?

The GRU01Z is a tool-only model that relies on Makita’s 40V max XGT batteries and chargers. XGT components are engineered to communicate digitally with the tool for optimized power, safety, and longer sustained performance under heavy loads.

• Tool-only — compatible with 40V max XGT batteries and chargers (sold separately)
• Digital communication between battery and tool for performance optimization
• Designed to replace gas tools for cord-free, lower-noise operation

Who is this for: The Makita GRU01Z suits professional landscapers, grounds crews, and demanding homeowners who need a cordless trimmer that rivals gas performance. Choose this model if you require a durable, high-torque 15" head, quick line changes, variable speeds, and compatibility with the 40V XGT battery ecosystem to keep heavy-duty trimming tasks moving efficiently.
