Your needs, this model
Does it fit your priorities?
Do you want a single 40V box with a blower, attachment-capable trimmer, 4.0 Ah battery and charger?
Greenworks lists model STBL40L301 / SKU 1346302 with a 550 CFM blower, 16-inch attachment-capable trimmer, one 4.0 Ah battery and a 2A single-port charger. The one pack moves between tools; they are not simultaneous.
Explore this need in the finder →Is 550 CFM enough, or is a higher published maximum essential?
This exact blower is listed at 550 CFM: it meets an inclusive 550 floor, but not 551 CFM.
Explore this need in the finder →Must one included battery be at least 4.0 Ah?
Yes, the exact kit lists one 4.0 Ah pack. A 4.1 Ah per-pack minimum excludes it.
Explore this need in the finder →Do you want a bump-feed head on the included trimmer?
The exact product specification lists bump line feed and a dual line .095-inch setup. It does not identify a proprietary Rapid Reload, POWERLOAD, or Speed-Feed 400 head.
Explore this need in the finder →Must the included trimmer accept optional attachments?
Yes. The exact page marks the trimmer attachment-capable and lists compatible edger, hedge, pole-saw, cultivator and blower attachments. Those attachment heads are separate from this combo kit.
Explore this need in the finder →The Greenworks STBL40L301 (SKU 1346302) is a two-tool 40V package rather than a blower-only bundle. Its appeal is the combination: a handheld blower rated at 550 CFM and 130 mph sits beside a 16-inch string trimmer that accepts optional attachments. The box listing includes one 4.0 Ah battery and a 40V 2A single-port charger. That is a useful starter setup for someone who wants to edge a lawn and then clear clippings from a driveway, but it is not two independent power systems. You move the single battery between tools and work through them in sequence.
What the exact kit does well
The blower's published 550 CFM is meaningfully above the smaller 390 CFM Greenworks STBA40B210 combo. It should interest homeowners who want a trimmer-and-blower kit but do not want the blower to be merely a light patio sweeper. The 130 mph figure is also the maker's maximum, not a field test or a guarantee against wet, matted leaves. On ordinary cleanup, the adjustable trigger, cruise control and Turbo button give you ways to vary the air stream instead of using maximum output for every pass. Greenworks describes a concentrator-nozzle feature for getting into corners, though the kit's included-items list does not separately inventory nozzle attachments; confirm the delivered tube/nozzle rather than assuming a separate accessory is in the box.
The trimmer is the other reason to choose this model. The page lists a 16-inch cut, .095-inch dual line, bump feed and an attachment-capable shaft. Greenworks names optional edger, hedge, pole-saw, cultivator and blower attachment heads as compatible. That lets a buyer who already prefers one powerhead plan consider expanding later, but the extra heads are not part of the STBL40L301 combo. If you only need a blower or already have a trimmer, the second tool may be redundant weight and storage rather than added value.
One battery is the practical constraint
The package's 4.0 Ah battery is a larger included pack than the 2.0 Ah one in the lower-output STBA40B210 combo. It does not mean the battery runs both machines at once: remove it from one tool and fit it to the other. A sequence of trimming, switching tools and clearing the hard surfaces is a real operating plan; simultaneous work is not. If your yard is large, heavily overgrown, or you want to trim while another person blows, one shared battery can be the bottleneck. Buying another compatible 40V pack may address downtime, but it changes the cost and contents of the package you are comparing.
Greenworks' page says the blower may run up to 34 minutes on high with a full 4 Ah battery, but the component description also says the battery is not included even though this exact combo includes one. The manufacturer does not explain the test conditions, and the number does not describe a mixed blower-and-trimmer session or how much of a particular yard you can finish. Treat it as a qualified product-page ceiling, not an ownership result. The 2A single-port charger is specified, but the exact charger model and an exact-kit recharge time are not established by the reviewed listing.
Controls, line and attachment choices
On the blower, variable trigger control and cruise control can help you use less than maximum flow when moving dry leaves off a porch or avoiding debris thrown across a driveway. Turbo is available when you want the listed peak, but frequent maximum use is precisely when battery demand rises. No exact-model sound rating, blowing-force value, bare-tool weight or ready-to-use weight appears in the reviewed sources, so this is not the right choice if one of those numbers is an essential hard limit.
The trimmer's bump-feed line system is different from Greenworks' automatic trigger-restart system on some smaller combo kits and from named systems such as EGO POWERLOAD or ECHO Speed-Feed 400. Its .095-inch dual line and 16-inch cutting path suit a buyer who wants a larger trimmer role in the same purchase. The attachment-ready design is a stronger differentiator than the blower's voltage label alone: confirm which compatible head you need and its separate cost before buying. The manufacturer says the 40V family works across many tools, but 40V is not interchangeable with its 24V, 60V or 80V families.
How it compares
Choose the STBA40B210 instead if you want a simpler, smaller 40V blower/trimmer bundle and can accept its listed 390 CFM blower, 12-inch trimmer and 2.0 Ah pack. It explicitly is not attachment-capable. The EGO ST1502LB is another two-tool option: its published blower maximum is 530 CFM and it includes a 15-inch trimmer, while using EGO's separate battery system. The Greenworks STBL40L301 raises the listed blower maximum to 550 CFM and offers an attachment-capable 16-inch trimmer, but whether that difference matters depends on the yard and the tools you will actually use. If you only need air movement, compare a blower-only model instead of paying for a trimmer you will store unused.
Who should buy it?
This kit fits a homeowner starting or extending a Greenworks 40V collection who wants a trimmer plus a moderate-to-strong published blower maximum, values attachment compatibility, and can finish the two jobs one after another with a shared battery. It is less convincing for large properties needing long continuous sessions, buyers who require separate batteries for each machine, or anyone who needs verified tool weights, numeric noise limits or a guaranteed runtime. The exact product page lists a three-year limited tool and battery warranty, subject to its terms. Its linked PDFs identify component model families rather than the STBL40L301 kit code, so keep the label and documentation supplied with the package when ordering parts or resolving a service question.
