Makita 18V LXT Brushless Cordless String Trimmer Kit

Worth it for contractors who need quiet operation and reliable 60-minute runtime. The brushless motor delivers 6,000 RPM on high speed, and the kit handles everything from residential trimming to noise-sensitive commercial properties. At 6.6 lbs with battery, it’s significantly lighter than gas trimmers for extended use.

Skip it if you’re clearing heavy brush or need all-day runtime without battery swaps. This kit shines in residential lawn maintenance, hospital grounds, school properties, and anywhere noise complaints cost contracts.

Performance That Actually Matters

The brushless motor changes the game. You get up to 60 minutes runtime with a 4.0Ah battery under low load — that’s enough to handle most residential properties without swapping batteries. Real-world average use drops that to 30-35 minutes, but that still beats hauling gas cans around job sites.

Automatic Torque Drive deserves credit here. The system automatically shifts between 4,000-6,000 RPM based on load. Hit thick grass? It ramps up power. Edging along sidewalks? It drops down to save battery. No fiddling with settings while you work.

Specification	Value
High Speed	6,000 RPM
Low Speed	4,500 RPM (XRU23) / 4,000 RPM (XRU12)
Cutting Swath	13 inches (XRU23) / 11-3/4 inches (XRU12)
Line Diameter	0.080” or 0.095” (twisted quiet line recommended)
Runtime	Up to 60 minutes (4.0Ah battery, low load)
Average Runtime	~30-35 mins (average use)

The reverse rotation system earns its keep when you hit fence lines. Instead of shutting down to untangle grass wraps, hit reverse and clear the head in seconds. Time saved on every property adds up by end of day.

Weight and Handling Reality

At 6.6 lbs with battery on the XRU23, this trimmer weighs about half what comparable gas units do. The 67-inch overall length gives proper reach without forcing you to hunch. Straight shaft with M10 x 1.25 LH arbor means you can swap heads if needed.

The weight difference shows up after hour three. Your shoulders notice. Your back notices. The crew notices when they’re not complaining about fatigue by lunch. Loop handle attaches with a hex wrench, protector screws on with standard Phillips head — basic hand tools get it assembled.

XPT (Extreme Protection Technology) keeps dust and moisture out of the motor. Montana’s variable weather — from morning dew to afternoon dust — won’t kill the internals. Not waterproof, but it handles job site conditions without babying.

Noise Matters More Than You Think

Zero emissions and low noise make this trimmer suitable for hospitals, schools, and residential neighborhoods. Montana municipalities enforce noise ordinances stricter than you’d expect. Billings hospitals have specific quiet hours. Missoula schools limit equipment noise during class time. Gas trimmers generate complaints. This doesn’t.

Professional landscapers report that the low noise levels open up early morning and late evening work windows. Start at 6 AM without waking neighborhoods. Work past 7 PM without ordinance violations. The quiet operation translates directly to more billable hours.

Battery Platform Economics

Compatible with over 325 tools in Makita’s 18V LXT system. If your crew already runs Makita drills, saws, and impacts, the batteries interchange. No separate charger systems. No incompatible inventory. The kit includes one 4.0Ah battery and rapid charger — 45-minute charge time gets you back to work.

Star Protection prevents overload, over-discharge, and overheating. The tool and battery talk to each other, shutting down before damage occurs. Beats replacing fried motors or cooked battery packs.

Cold-weather performance matters here. Lithium batteries lose 20-40% capacity below freezing, and Montana spends months there. Keep spare batteries warm in the truck. Rotate them through the day. The electronic speed control maintains RPM under load, so you’ll get consistent cutting even as battery voltage drops in cold weather.

What’s Actually In The Box

The kit includes the trimmer tool, one 4.0Ah battery, rapid charger, bump-feed head pre-loaded with line, hex wrench, and safety guard. Everything needed to start working, except spare line. The bump-feed head loads in seconds — rapid-load design that actually works.

Models covered include XRU23SM1 and XRU12SM1. The XRU23 gives you the 13-inch swath and lighter weight. The XRU12 has a slightly smaller cutting width but similar performance specs.

Bottom Line for Montana Contractors

Makita’s warranty covers 3 years on the tool and 3 years on battery/charger when used with genuine Makita batteries. UL Listed for safety, with Makita’s Star Protection and XPT standards built in.

This trimmer makes sense for landscape maintenance crews working residential routes, property management companies with noise-sensitive contracts, and anyone tired of mixing gas and oil. The 60-minute runtime handles typical Montana lot sizes. The quiet operation opens up more working hours. The 6.6-pound weight saves operator fatigue.

Not built for clearing fence rows or attacking woody brush. Gas still wins for all-day commercial use without battery management. But for what it’s designed to do — professional trimming and edging in noise-sensitive environments — it delivers.

FAQ

How long does the battery really last in normal use? Average runtime is 30-35 minutes per 4.0Ah battery under typical conditions. Low-load trimming extends to 60 minutes. Buy extra batteries for all-day use.

Can it handle thick Montana grass? Automatic Torque Drive adjusts power from 4,000-6,000 RPM based on resistance. The 0.095” twisted line option handles thicker growth. Won’t match gas power in heavy brush.

What about wet morning grass? XPT protection provides dust and water resistance for harsh conditions. Morning dew won’t kill it, but it’s not designed for soaking wet conditions.

Is assembly complicated? Basic hand tools handle assembly — hex wrench for the loop handle, Phillips screwdriver for the guard. Takes about 10 minutes.

Does it work with older Makita batteries? Works with any Makita 18V LXT battery that has the Star Protection symbol. Over 325 compatible tools in the system.
