String Trimmer: General Overview and Optimal Selection

String trimmers, often called weed eaters or weed whackers, are fundamental tools for garden maintenance. They excel at cutting grass and weeds in areas that lawnmowers can’t reach, such as around fences, trees, garden beds, and along pathways. Their flexibility and precision make them essential for achieving a clean, polished look in any landscape.

The market offers three primary types of string trimmers: gas-powered, corded electric, and battery-powered. Gas models typically offer the most power and mobility for large, demanding jobs but come with higher noise, emissions, and maintenance. Corded electric trimmers are lightweight and require minimal maintenance, but their reach is limited by the power cord. Battery-powered string trimmers, like the Makita 18V LXT, strike a balance, offering excellent mobility, lower noise, zero emissions, and reduced maintenance, making them increasingly popular for both homeowners and professionals.

Detailed Buying Guide for String Trimmers

Choosing the right string trimmer involves considering several critical factors that align with your specific lawn care demands and preferences. Understanding these elements ensures you select a tool that not only performs effectively but also offers comfort and longevity.

Motor Type

The heart of any string trimmer is its motor, dictating its power, efficiency, and environmental impact.

Gas-powered trimmers typically feature 2-cycle or 4-cycle engines, known for their raw power and ability to tackle dense brush and large areas without interruption. However, they are noisy, produce exhaust fumes, and require regular fuel mixing and engine maintenance.
Corded electric trimmers use an electric motor powered directly from an outlet. They are lightweight, quiet, emission-free, and start instantly. Their main drawback is the need for an extension cord, limiting mobility and posing a tripping hazard.
Battery-powered trimmers run on rechargeable lithium-ion batteries and utilize brushless motors for greater efficiency and power. They offer the freedom of gas trimmers without the noise, fumes, or maintenance. Their performance has improved dramatically, with many models now rivaling their gas counterparts for everyday tasks. The Makita 18V LXT system, using two 18V batteries for 36V power, provides significant cordless convenience and robust performance.

Power and Performance

The appropriate power level for your string trimmer largely depends on the size of your yard and the type of vegetation you typically encounter. For light trimming around a small urban garden, a less powerful model suffices. However, if you have a larger property with thick weeds and tall grass, a more robust trimmer is essential.
The Makita 18V LXT Brushless String Trimmer (specifically models like the XRU15) features an Outer Rotor BL Brushless Motor. This direct-drive system is engineered to provide high power and increased torque, allowing it to cut through dense grass and weeds effectively. A key innovation is the Automatic Torque Drive Technology, which dynamically adjusts RPM from 3,500 to 6,500 based on the load, optimizing either for extended runtime or for an immediate power boost when encountering tougher patches. This intelligent power management ensures consistent cutting performance while maximizing battery life.

Trimmer Head and Line

The trimmer head and the type of line it uses are crucial for cutting efficiency and versatility. Most string trimmers come with either a fixed-line head or a bump-feed head.

Bump-feed heads are the most common, allowing users to extend more line by tapping the head on the ground while the trimmer is running. The Makita XRU15 comes with a bump-feed trimmer head, pre-loaded with 0.080-inch twisted quiet line, which is suitable for general grass and light weed trimming. For more aggressive cutting, the head can typically accommodate a 0.095-inch line, offering increased mass for tackling tougher vegetation.
Consider the cutting swath (the width the trimmer cuts in one pass). The Makita XRU15 features a 15-inch cutting swath, a versatile size that offers a good balance between productivity for larger areas and maneuverability for precise trimming. A wider swath covers more ground faster, while a narrower one is better for intricate work.

Additional Features

Modern string trimmers come with a host of features designed to enhance user experience, safety, and durability.

Speed Control: Multiple speed settings, like the low (3,500 RPM), medium (5,300 RPM), and high (6,500 RPM) options on the Makita XRU15, allow you to match the power output to the task, conserving battery for lighter jobs and unleashing full power for dense growth.
Anti-Vibration Systems: Reduce user fatigue, especially during extended use. While the XRU15 is already relatively light at around 10.4 lbs with batteries, good balance and a comfortable adjustable loop handle contribute to user comfort.
Safety and Durability: Features like a protective guard, trigger interlocks, and robust construction are vital. Makita’s Extreme Protection Technology (XPT) provides enhanced resistance to dust and water, making the trimmer more durable in challenging outdoor conditions. Furthermore, Star Protection Computer Controls safeguard against overloading, over-discharging, and overheating, extending both tool and battery life. A reverse rotation function is also invaluable for quickly clearing entangled grass and weeds from the trimmer head, preventing downtime.

In-Depth Review of Top String Trimmers

Understanding the individual strengths and weaknesses of top models can significantly narrow down your choice. Here, we delve deeper into the Makita XRU15 and offer a brief look at some strong alternatives.

Makita 18V LXT Brushless String Trimmer (XRU15)

The Makita XRU15 is a standout in the cordless string trimmer category, particularly for those already invested in Makita’s extensive 18V LXT battery platform. It effectively bridges the gap between the convenience of battery power and the performance often associated with gas models, thanks to its clever 18V X2 (36V equivalent) design.

Design and Ergonomics: The XRU15 boasts a robust yet lightweight design, typically weighing around 10.4 pounds with two 5.0Ah batteries. This balance significantly reduces operator fatigue during prolonged use. Its overall length of 69-1/4 inches, combined with an adjustable loop handle, allows for comfortable operation and excellent maneuverability, making it ideal for precision trimming and edging. The trimmer’s motor is positioned for optimal balance, contributing to a more natural and less strenuous working posture.

Performance and Power: Equipped with a powerful outer rotor brushless motor, the XRU15 delivers impressive cutting performance. Its three-speed settings—low (3,500 RPM), medium (5,300 RPM), and high (6,500 RPM)—provide precise control for various tasks. The Automatic Torque Drive Technology is a game-changer, intelligently sensing when more power is needed and adjusting the RPM accordingly. This feature ensures consistent cutting without bogging down, even in thicker grass, and helps conserve battery life when only light trimming is required. The 15-inch cutting swath allows for efficient coverage of medium to large yards.

Durability and Features: Makita’s commitment to durability is evident in the XRU15. The Extreme Protection Technology (XPT) protects the internal components from dust and moisture, extending the tool’s lifespan in harsh outdoor environments. The reverse rotation function is a practical addition, allowing users to quickly clear tangled grass or weeds from the trimmer head with a simple button press. The bump-feed head is reliable and easy to load with 0.080-inch twisted quiet line, though it can handle up to 0.095-inch for more demanding jobs.

Pros:

Excellent power and torque for a battery-powered unit, rivaling light-duty gas trimmers.
Quiet operation and zero emissions, contributing to a more pleasant user experience and environment.
Impressive runtime, especially on lower speed settings (up to 90 minutes with two 5.0Ah batteries).
Lightweight and well-balanced design for reduced user fatigue.
Automatic Torque Drive Technology optimizes power and runtime.
Part of the extensive Makita 18V LXT system, ideal for users with existing batteries.
Durable construction with XPT for enhanced protection.
Reverse rotation function is highly convenient for clearing tangles.

Cons:

Requires two 18V batteries, which adds to the initial cost if you don’t already own Makita LXT tools and batteries.
While powerful, it might not entirely replace a heavy-duty gas trimmer for extremely dense brush clearing over very large areas.
The 15-inch cutting swath, while versatile, is slightly smaller than some of the largest professional-grade battery trimmers available.

String Trimmer Usage and Maintenance Guide

Proper usage and consistent maintenance are key to maximizing the lifespan and efficiency of your string trimmer. Adhering to these guidelines ensures both safety and optimal performance.

Before Using Your String Trimmer

Safety should always be your top priority. Before starting any trimming work, take a few moments to prepare:

Inspect the Trimmer: Check the trimmer head for any damage or excessive wear. Ensure the cutting line is adequately spooled and in good condition. For battery trimmers, confirm the battery is fully charged and securely seated.
Clear the Area: Remove any debris, rocks, branches, or other objects from your trimming path that could be thrown by the line or damage the trimmer.
Wear Protective Gear: Always wear safety glasses or goggles, long pants, sturdy closed-toe shoes, and hearing protection, especially with more powerful models. Gloves are also recommended for better grip and vibration absorption.
Read the Manual: Familiarize yourself with your specific trimmer’s controls and safety features, including how to start, stop, and operate it safely.

Effective Trimming Techniques

Using the correct technique not only ensures a cleaner cut but also makes the job easier and safer.

Maintain Proper Stance: Hold the trimmer firmly with both hands, keeping it balanced and comfortable. Maintain a stable stance with your feet shoulder-width apart.
Sweep Motion: Use a gentle, sweeping motion, moving the trimmer from side to side. Avoid swinging it too aggressively, which can lead to uneven cuts and greater fatigue.
Angle for Edging: When edging along a path or driveway, tilt the trimmer head to a 90-degree angle to create a crisp, clean line. For general trimming, keep the head parallel to the ground.
Avoid Overloading: For thick patches of weeds, take smaller passes rather than trying to cut through everything at once. This prevents the motor from bogging down and conserves battery life. The Makita XRU15’s Automatic Torque Drive will help manage this by providing extra power when needed.
Work Away from Objects: Keep a safe distance from delicate plants, trees, and other objects to avoid accidental damage.

Cleaning and Maintenance

Regular cleaning and maintenance will significantly extend the life of your Makita string trimmer.

Disconnect Power: Always remove the battery before performing any cleaning or maintenance.
Clean After Each Use: Use a stiff brush or cloth to remove grass clippings, dirt, and debris from the trimmer head, shaft, and motor housing. Pay close attention to air vents to prevent overheating.
Inspect and Replace Line: Regularly check the trimmer line for wear and tear. Replace it when it gets too short or damaged. Follow the manufacturer’s instructions for reloading the bump-feed head.
Check for Loose Fasteners: Periodically inspect all screws, bolts, and fasteners to ensure they are tight. Tighten any that are loose.
Store Properly: Store your string trimmer in a dry, clean place, away from extreme temperatures and direct sunlight. For battery models, store batteries separately in a cool, dry place when not in use.

Where to Buy a String Trimmer?

When you’re ready to purchase a new string trimmer, you have several reliable options, both online and in physical stores. The best choice often depends on your preference for hands-on inspection versus convenience and competitive pricing.

Online Retailers: Websites like Amazon, Home Depot, Lowe’s, and specialty outdoor power equipment sites offer a vast selection of string trimmers, including the Makita 18V LXT models. Buying online often provides competitive pricing, a broader range of models, and convenient delivery directly to your home. It’s also easy to compare specifications and read user reviews from various sources.

Physical Stores: Local hardware stores, garden centers, and large home improvement retailers provide the advantage of seeing and handling the trimmer before purchase. You can assess its weight, balance, and ergonomic feel, and speak with sales associates who can offer advice. Many stores also offer assembly services and have staff available for questions about usage and maintenance. For Makita tools, authorized dealers can provide specialized support and genuine accessories.
