Most string trimmers do one job. The Wild Badger 40V 4-in-1 string trimmer does four, swapping between a grass trimmer, a pole saw, a hedge trimmer, and a brush cutter on one cordless powerhead. That range is exactly why it earned outside recognition this year, and it is what makes the tool worth a closer look if you want to shrink a shed full of yard gear down to a single machine.
Here is what the 4-in-1 is, why it was singled out, what it actually includes, and who it fits best.
Recognized as a Best of the Year Multitool
The reviews site Reviewed named the Wild Badger 40V Electric Weed Wacker 4-in-1 its Best String Trimmer Multitool in the Best of the Year 2026 home roundup. Their editors pointed to the same thing owners tend to notice first: this is a trimmer that keeps going long after the grass is done.
Reviewed described the tool as going "far beyond grass edges, serving as a multipurpose device," and noted that testers appreciated "the durable attachments and the long battery life from the dual 20V batteries, which give the 4-in-1 Tool a total of 40V."
An independent nod like that is a useful signal, but the real test is whether the tool fits your yard. The rest of this review breaks down what you are actually getting.
The Quick Take
Buy the 40V 4-in-1 if you want one cordless tool that trims grass, edges, cuts high branches, shapes hedges, and clears heavy brush, all on the same battery platform. It suits homeowners who would rather store, charge, and learn one machine than four.
Look elsewhere only if you need continuous all-day commercial runtime or a single dedicated tool you use for hours at a stretch. For typical home yard care, the multitool covers the whole list.
What Makes It a 4-in-1
The 4-in-1 is built around one brushless powerhead that accepts four cutting heads. You keep the same motor, battery, and controls, and change the tool on the end to match the task.
- String trimmer and edger. The 15-inch cutting swath knocks down grass and weeds fast, and the same head turns on edge to cut a clean line along sidewalks, driveways, and beds.
- Pole saw. An 8-inch pole saw head reaches up into branches you would otherwise need a ladder for, which makes light limbing and storm cleanup a lot safer.
- Hedge trimmer. A 16-inch hedge trimmer head shapes shrubs and hedges without a second dedicated tool.
- Brush cutter. A 10-inch brush cutter blade handles thick, woody growth and overgrown areas that a plain string head would just bounce off.
That is the whole appeal: five common yard jobs, one tool you carry to the shed and charge. You can see how it sits next to the rest of the range on the string trimmer collection page.

The 40V Battery Platform, Explained
The part that trips people up is the power label. The 4-in-1 runs on two 20V batteries that work together to deliver a 40V system, which is where the balance of power and runtime comes from. Two packs sharing the load is what lets the tool keep a steady 18,000 RPM through the string head and still have the torque to swing a brush cutter blade through woody growth.
A brushless motor helps here too. Compared with an older brushed design, brushless motors run cooler, waste less energy as heat, and last longer, so more of each charge goes into cutting rather than into the motor itself. For a tool you switch between five jobs, that efficiency is what keeps you working instead of waiting on a charger.
If you already run other Wild Badger 40V tools, the platform logic works in your favor. A tool like the 40V axial blower attachment lives on the same 40V system, so batteries and chargers do double duty across the tools you own.
Where It Shines in Real Use
One tool for the whole yard walk
The everyday win is not any single attachment; it is the walk around the yard without a trip back to the shed. Trim the lawn edges, switch to the pole saw for a low branch, drop on the hedge trimmer for the front shrubs, and finish with the brush cutter along the back fence. One battery platform, one tool in your hands.
Cordless convenience with no fuel
Because it is battery powered, there is no fuel to mix, no pull cord, and no engine to warm up. You pull the trigger and you are working, and the tool runs quiet enough for early morning or evening yard time without waking the street.
Storage and upkeep that stay simple
Four tools in one is four things you are not storing, maintaining, or buying separately. The heads stow compactly, the batteries charge off one system, and there are no carburetors or spark plugs to service across the set. The whole kit is backed by a 3-year warranty.
Who Should Buy It
- Homeowners with a mixed yard: grass, edges, shrubs, a few trees, and some rough growth. The 4-in-1 covers all of it on one platform.
- Anyone tired of a crowded shed: if you are looking at buying a separate trimmer, pole saw, hedge trimmer, and brush cutter, this consolidates the whole list.
- Cordless-first buyers: people who want quiet, fume-free, grab-and-go tools and are happy to charge batteries rather than mix fuel.
- Wild Badger platform owners: if you already have 40V tools, the shared batteries make this an easy add.
For a plain grass-and-edge routine, a dedicated trimmer is still a fine choice, and you can compare the options on the trimmers collection. But if your list runs past the lawn, the 4-in-1 is built to be the one tool that finishes it.
Frequently Asked Questions
Is the Wild Badger 40V 4-in-1 a real 40V tool?
Yes. It runs on two 20V batteries that combine to deliver a 40V system, which is what powers the brushless motor to 18,000 RPM. Reviewed specifically highlighted the long battery life from that dual-battery setup when it named the tool Best String Trimmer Multitool.
What four tools are included?
A 15-inch string trimmer and edger head, an 8-inch pole saw, a 16-inch hedge trimmer, and a 10-inch brush cutter, all running on the same powerhead and battery.
Can it cut thick brush, not just grass?
Yes. The 10-inch brush cutter blade is made for woody, overgrown growth that a string head cannot handle, which is a big part of why it is described as going far beyond grass edges.
Do I need to mix fuel or maintain an engine?
No. It is fully cordless, so there is no fuel mixing, no spark plug, and no carburetor. You charge the batteries and swap heads as needed.
How heavy is it?
The full kit is around 27 pounds including all four attachments and the batteries. In use you are only holding the powerhead plus one head at a time, not the entire set.
