Makita XRU15PT 36V (18V x2) LXT Brushless String Trimmer Kit (substituted for Milwaukee M18 FUEL String Trimmer): What to Know
This slot in the lineup originally went to the Milwaukee M18 FUEL String Trimmer. We could not verify a legitimate way to buy it on Amazon: Milwaukee Tool does not authorize Amazon.com as a retailer, and reporting from ToolGuyd and SlashGear confirms every Milwaukee listing on Amazon comes from third-party sellers operating outside Milwaukee's official distribution network, meaning no manufacturer warranty and a documented risk of counterfeit batteries and tools. We're not going to send readers toward a purchase like that, so we substituted the Makita XRU15PT, a trimmer built on the same 'combine two of your existing 18V packs' logic contractors like about the Milwaukee M18 platform, and confirmed it as a real, current, in-stock Amazon listing (ASIN B07X13FYSL).
The XRU15PT runs on two Makita 18V LXT batteries wired together for 36V of output, which is the same idea behind Milwaukee's M18-based tools: if you already own a stack of 18V LXT batteries from other Makita tools, this trimmer taps into that existing battery investment instead of asking you to buy into a separate voltage platform. The kit we verified includes two 5.0Ah batteries and a charger.
Makita's own spec pages list this trimmer's cutting swath at 15 inches, and the motor is Makita's Outer Rotor Brushless design with three selectable speeds (3,500 / 5,300 / 6,500 RPM) plus an Automatic Torque Drive mode that shifts speed on its own based on load. Line feed is a standard bump-feed head loaded with 0.080-inch twisted line. Note this is a dedicated string trimmer, not part of Makita's separate 'Couple Shaft' attachment system that lets one power head swap between trimmer, edger, and other heads; if attachment flexibility matters to you, that's a different Makita product line entirely.
On weight, Makita's own product pages state roughly 7.6 lbs without a battery and 10.4 lbs with batteries installed, though we noticed a couple of much lower figures (around 4 to 5.5 lbs) surface in unrelated bullet points on the Amazon listing itself, which appear to describe accessories or shipping components rather than the trimmer; we're flagging that discrepancy rather than picking whichever number sounded better.
