CRAFTSMAN CMCST900D1 vs Greenworks 2101602: Which One Fits Your Yard?
Start with the battery platform you already use: the CRAFTSMAN kit is V20, while the Greenworks kit is 40V. The CMCST900D1 lists a 13-inch cut path, telescoping pole, and edging conversion; the Greenworks 2101602 lists a 12-inch path and adjustable auxiliary handle. Both official pages list a 2.0 Ah battery and charger, and both describe automatic line feed, so choose by platform and the listed setup features rather than an untested performance claim.

Choose Greenworks 2101602 40V 12-Inch Cordless String Trimmer Kit if

When the recommendation changes

The differences that matter
Battery Platform And Kit Fit
CRAFTSMAN CMCST900D1 V20 Cordless String Trimmer and Edger Kit
Cordless CRAFTSMAN V20 model; official kit list includes V20 2.0 Ah battery and charger; manufacturer says V20 platform is compatible with CRAFTSMAN V20 outdoor equipment and power tools.[1]
Greenworks 2101602 40V 12-Inch Cordless String Trimmer Kit
Cordless Greenworks 40V model; official kit list includes one 40V 2.0 Ah battery and charger; manufacturer says Greenworks 40V batteries power 75+ Greenworks tools.[2]
What this changes: Check your existing tool battery family and selected kit contents; do not assume cross-brand battery fit or a tool-only saving.[1, 2]
Listed Cutting Path And Adjustment
CRAFTSMAN CMCST900D1 V20 Cordless String Trimmer and Edger Kit
13-inch cutting swath, telescoping pole, turn-to-edge function.[1]
Greenworks 2101602 40V 12-Inch Cordless String Trimmer Kit
12-inch cutting path, adjustable auxiliary handle.[2]
What this changes: Compare listed setup features and path for your intended layout; no real-world coverage, ease, comfort or performance result follows from these specifications.[1, 2]
Best for your routine
You already use CRAFTSMAN V20 tools and want another tool from that documented platform.
Best fit: CRAFTSMAN CMCST900D1 V20 Cordless String Trimmer and Edger Kit
Based on listed features, not comparative testing.
The CMCST900D1 is listed as a V20 model and CRAFTSMAN says the V20 platform works with its outdoor equipment and power tools. This is a platform-fit recommendation, not a claim that the tool performs better.
You already use Greenworks 40V tools and want another tool from that documented platform.
Best fit: Greenworks 2101602 40V 12-Inch Cordless String Trimmer Kit
Based on listed features, not comparative testing.
Greenworks lists the 2101602 in its 40V family and describes 40V batteries as powering more than 75 Greenworks tools. This is a platform-fit recommendation, not a performance claim.
Your preference depends on pole adjustment, auxiliary-handle adjustment, or the listed cut path.
The better fit depends on your priorities
The official pages list different setup features and a 13-inch versus 12-inch cut path. Select the configuration you want; the listings do not establish real-world comfort or coverage superiority.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
No durable price winner is established. Compare current selected kit offers and consider whether your preferred battery platform and listed setup features justify any current price difference.
Historical price context was not established, so this result offers no timing recommendation.
Limitations
- No hands-on use or independent side-by-side test was performed; cutting performance, runtime, comfort, noise, and durability are not ranked.
- The listed 13-inch and 12-inch cut paths are specifications, not proof of real-world area coverage or trimming speed.
- The CRAFTSMAN page lists a telescoping pole and an auxiliary handle; it does not state in the reviewed material whether that auxiliary handle is adjustable. The Greenworks page lists an adjustable auxiliary handle; its reviewed material does not establish whether its pole telescopes.
- Both official product pages list a battery and charger, but buyers should confirm the current selected seller and package before purchase.
Questions shoppers ask
Do both kits include a battery and charger?
Yes. CRAFTSMAN lists a V20 2.0 Ah battery and charger for the CMCST900D1 kit. Greenworks lists one 40V 2.0 Ah battery and charger for the 2101602 kit. Verify the selected package before ordering.
Which trimmer cuts faster or handles thicker weeds better?
The reviewed manufacturer pages give feature specifications, not a comparable cutting-speed or thick-weed test. This comparison does not name a performance winner.
