The CRAFTSMAN V20 4Ah trimmer and edger kit suits homeowners who want a 13 in swath, two speeds and a battery and charger in the box. Its brushless sibling adds adjustable 11–13 in cutting width and push-button line feed, so the better fit depends on which features matter in your yard.
Both are cordless V20 tools that can trim and edge. We compared their stated features with two lighter 20V alternatives, the WORX WG163 review and a BLACK+DECKER model.
What does the CRAFTSMAN V20 string trimmer offer?
The standard V20 kit pairs a 13 in cutting swath with two speed settings and Turn-To-Edge functionality. It includes a 4Ah battery, charger and a spool that feeds 0.065 in line.
CRAFTSMAN V20 Trimmer and Edger Kit (4Ah): Best for longer low-speed sessions
- 13 in cutting swath
- Up to 63 minutes runtime
- Two speed settings
- Turn-To-Edge function
A V20 kit with a 4Ah battery and charger, adjustable handle, two speeds and a turn-to-edge function. The stated runtime is up to 63 minutes on low speed.
Pros
- Battery and charger included
- Two speed settings
- 13 in cutting swath
- Turns from trimming to edging
Cons
- Runtime figure applies to low speed
- No weight stated
CRAFTSMAN states up to 63 minutes of runtime per charge on low speed with the included battery. The brand also describes 52% more power on average compared with the CMCST915 trimmer when using the same 4Ah battery, based on its stated measurement method.
Treat both figures as maker claims tied to particular conditions. High speed, thick growth and edging can change how long a charge lasts.
Is the brushless V20 kit a better fit?
The brushless kit makes sense if adjustable swath width and push-button line feed are priorities. Its 5Ah battery and charger are included, and CRAFTSMAN states up to 75 minutes runtime.
CRAFTSMAN V20 RP Brushless Trimmer and Edger Kit: Best for adjustable swath width
- Brushless motor
- Adjustable 11–13 in swath
- Up to 75 minutes runtime
- Push-button line feed
This brushless V20 kit includes a 5Ah battery and charger, adjustable swath width and push-button line feed. CRAFTSMAN states up to 75 minutes of runtime.
Pros
- Brushless motor
- Adjustable 11–13 in swath
- Push-button feed
- 5Ah battery and charger included
Cons
- Heavier than the listed BLACK+DECKER and WORX alternatives
- No two-speed setting stated
Its cutting swath adjusts from 11 to 13 in, which lets you choose a narrower cut or cover more ground per pass. The listed weight is 9.4 lb, so consider how long you expect to carry it.
CRAFTSMAN says its brushless motor provides up to 80% more runtime and up to 75 minutes runtime. Those are separate stated claims, not a guarantee for every yard or setting.
How do the two CRAFTSMAN V20 trimmers compare?
The 4Ah kit has two speed settings, while the brushless kit offers an adjustable cutting width and push-button feed. Both include a battery and charger and are described as trimmer and edger kits.
| Feature | V20 4Ah kit | V20 RP brushless kit |
|---|---|---|
| Cutting swath | 13 in | Adjustable 11–13 in |
| Battery included | 4Ah | 5Ah |
| Runtime stated | Up to 63 minutes on low speed | Up to 75 minutes |
| Line feed | Spool feeds 0.065 in line | Push-button feed |
| Edging | Turn-To-Edge functionality | Trimmer and lawn edger |
| Weight stated | Not stated | 9.4 lb |
Choose the 4Ah kit if you want simple speed control and a fixed 13 in swath. Pick the brushless kit if adjusting the swath or advancing line by button better fits your trimming routine.
Neither set of details gives a runtime under the same conditions, so the maximum figures alone don't settle which battery lasts longer in your yard. Your grass, pace, speed setting and trimming pattern all affect the charge you use.
How does the CRAFTSMAN V20 compare with other cordless trimmers?
The CRAFTSMAN kits have 13 in cutting swaths, while these BLACK+DECKER and WORX alternatives have 12 in swaths. They offer different line feed and edging details that may matter more than the small difference in width.
BLACK+DECKER 20V MAX 2-in-1 Trimmer and Edger: Best for automatic line feed
- 12 in cutting swath
- Automatic spool feed
- Trimmer-to-edger conversion
- 2Ah battery and charger included
A 20V kit with automatic line feed, a 12 in swath and a 2Ah battery and charger. It converts between trimming and edging.
Pros
- Automatic feed needs no bumping
- Battery and charger included
- Adjustable handle and height
Cons
- Smaller swath than the CRAFTSMAN kits
- No runtime figure stated
BLACK+DECKER's LST300 automatically feeds line when needed, so it doesn't require bumping the tool. It weighs 5.7 lb and includes a 2Ah battery and charger.
WORX WG163 20V 2-in-1 Trimmer and Edger: Best for guided edging
- 12 in cutting diameter
- Two 20V batteries
- Rubberized edger wheels
- 90-degree tilting head
This 20V trimmer and edger comes with two batteries, a charger, rubberized wheels and a head that tilts 90 degrees. Its push-button feed advances line on command.
Pros
- Two batteries and charger included
- Wheels guide edging
- Tilting head helps reach slopes and tight spots
Cons

What should you check before buying a CRAFTSMAN V20 trimmer?
Check swath width, line feed, weight and battery needs against the yard work you actually do. A wider cut can cover more ground per pass, while lighter listed weights may be easier to carry around garden beds.
The 4Ah CRAFTSMAN kit has two speed settings, giving you a choice between runtime and power. The brushless kit lets you adjust the cutting swath and advance line with a button.
If most of your work is edging along sidewalks, consider how the tool switches modes and whether wheels guide the cut. The WORX has rubberized wheels; the 4Ah CRAFTSMAN uses Turn-To-Edge functionality.
Battery compatibility can shape the long-term value of a kit. The CRAFTSMAN models use the V20 system, while the WORX batteries work with WORX 20V and 40V Power Share tools.
Our string trimmer buying guide explains how to compare power, weight and line for your yard. If trimming is only part of the job, see string trimmers with attachments for options that accept other tool heads.
Which CRAFTSMAN V20 string trimmer should you choose?
Pick the 4Ah kit for two speed settings and a fixed 13 in swath; choose the brushless kit for adjustable width and push-button line feed. If low carry weight matters most, compare the 5.5 lb WORX and 5.7 lb BLACK+DECKER alternatives with the CRAFTSMAN brushless model's stated 9.4 lb weight.
The CRAFTSMAN V20 lineup is easiest to choose when you start with your main task: routine trimming, controlled line feed or guided edging. Then check the included battery and the features you'll use on each pass.
