BLACK+DECKER 40V MAX* LST136 String Trimmer/Edger REVIEW: A Long-Term User’s Perspective

For years, I struggled with overgrown weeds and unruly edges around my property. The task seemed daunting, and the thought of wrestling with a gas-powered trimmer filled me with dread. A lightweight, efficient cordless solution would have saved me countless hours of back-breaking work and frustration. That’s why I eventually invested in a powerful trimmer, and I’m sharing my experience with the BLACK+DECKER 40V MAX* 13 in. 2in1 Cordless String Trimmer/Edger (LST136).

Factors to Consider Before Purchasing a Cordless String Trimmer

Cordless string trimmers offer a convenient and powerful way to maintain your lawn and garden. They eliminate the hassle of cords and the fumes of gas-powered models, making them ideal for smaller to medium-sized yards. However, not everyone is a suitable candidate for a cordless trimmer. If you have an expansive property or particularly dense vegetation, a more powerful, possibly gas-powered, trimmer might be necessary. Before making your purchase, consider the size of your yard, the density of the vegetation you need to tackle, and your budget. Think about the battery life—how long do you need it to run continuously?—and the weight of the unit. A lighter trimmer will be easier to maneuver, especially during prolonged use. Finally, check the warranty and availability of replacement parts and batteries.

Introducing the BLACK+DECKER 40V MAX* LST136

The BLACK+DECKER 40V MAX* LST136 is a 2-in-1 cordless string trimmer and edger. It promises powerful performance and versatile functionality. The kit includes the trimmer/edger, a 40V MAX* 2.0Ah lithium-ion battery, a fast charger, a spool of trimmer line, a guard, and an auxiliary handle. Compared to previous BLACK+DECKER models and some competitors, this model boasts a POWERCOMMAND dial for adjusting power and runtime, an automatic feed spool, and an improved ergonomic design. This trimmer is ideal for homeowners with moderate-sized yards who value convenience and ease of use. It’s less suited to professional landscapers or those with extensive, heavily overgrown areas.

* Pros:
* Versatile 2-in-1 design (trimmer and edger)
* POWERCOMMAND dial for power and runtime control
* Automatic feed spool (though this is a point of contention for some users, as detailed below)
* Lightweight and comfortable design
* Compatible with other BLACK+DECKER 40V MAX* tools

* Cons:
* Battery life could be longer for larger yards.
* The automatic feed spool can be unreliable for some users.
* Charger takes a relatively long time (6+ hours) to fully recharge the battery.
* The safety switch can be cumbersome.

A Deep Dive into the BLACK+DECKER 40V MAX* LST136’s Features

POWERCOMMAND Dial: Mastering Power and Runtime

The POWERCOMMAND dial is a game-changer. You can switch between max power for tackling tough weeds and max runtime for longer trimming sessions on lighter vegetation. This feature extends battery life significantly, making a single charge go further. Having this control is invaluable – I use max power for stubborn weeds and switch to a lower setting for general trimming. This feature alone significantly justifies the price.

Automatic Feed Spool: A Mixed Bag

The automatic feed spool is a convenience feature, designed for effortless line feeding. However, user reviews highlight inconsistent performance. While it works flawlessly for many, some users report needing to manually feed the line. My experience is somewhere in the middle. It works most of the time, but sometimes I still have to manually adjust it. This is the most significant drawback, and it’s essential to keep your expectations tempered.

High-Performance Battery and Charger: Power and Patience

The 40V MAX* lithium-ion battery offers a decent runtime, but as mentioned, it’s not infinite. I found the battery lasts about 30-45 minutes on a single charge, depending on the power setting. The 6+ hour charging time is a major drawback. This means having a spare battery is almost essential for those with larger lawns to avoid work interruptions. The fast charging is a significant plus over older models, yet it’s still longer than many competing brands.

Lightweight Design and Ergonomic Handle: Comfort and Control

The trimmer’s lightweight design and comfortable grip are key features that make trimming less tiresome. The adjustable height and soft-grip handle enhance comfort and control, particularly during extended use. The balance is excellent, reducing wrist strain. This feature is vital for preventing fatigue during longer sessions. The improved ergonomics are a vast improvement over older models.

2-in-1 Functionality: Trimming and Edging with Ease

The ability to quickly switch between trimming and edging is extremely convenient. The edging feature is particularly well-designed, allowing for precise edging along sidewalks, driveways, and flowerbeds. This versatility eliminates the need for separate tools. This 2-in-1 aspect is a substantial selling point for this BLACK+DECKER model.

What Others Are Saying: User Feedback on the BLACK+DECKER LST136

Online reviews paint a picture of a trimmer that mostly delivers on its promises. Many users praise its power, lightweight design, and 2-in-1 functionality. Some appreciate the compatibility with other BLACK+DECKER 40V MAX* tools. However, the inconsistent automatic feed spool and long charging time are recurring criticisms. Several users found the solution to the annoying safety button I mentioned earlier. Others suggest purchasing extra batteries for larger jobs.

Final Verdict: Is the BLACK+DECKER 40V MAX* LST136 Right for You?

The BLACK+DECKER 40V MAX* LST136 tackles overgrown weeds and unruly edges efficiently. Its lightweight design, convenient features such as the POWERCOMMAND dial, and versatile 2-in-1 functionality make it a winner. While some may be disappointed by the inconsistent automatic feed spool and lengthy charging time, its power and ease of use often outweigh these drawbacks.

It’s a solid choice, particularly for those with medium-sized yards who value ease of use and don’t mind the minor quirks.
