Greenworks STBA40B210 40V trimmer and blower combo review

A two-tool Greenworks starter package, not a blower-only bundle

The Greenworks STBA40B210, SKU 1301202, pairs a 40V handheld blower with a 12-inch string trimmer. The maker lists one 2.0 Ah battery and a charger in the box, so this is a complete starter kit for someone who needs both chores covered rather than a blower for an existing tool collection. The package keeps the blower in the modest-output range: Greenworks lists 390 CFM and 110 mph maximum air speed. Those are published maximums, not measured clearing time or a promise that the tool will move every wet pile or dense hedge row.

The included trimmer is also a compact setup. Its cutting path is 12 inches and its line is 0.065-inch nylon in a dual-line spool. Greenworks calls the head auto-feed. The linked manual explains the useful distinction: releasing and pulling the trigger again advances a short amount of line, and it warns not to bump the head to feed it. That saves the user from the usual bump-feed motion, but it is not the button-wound EGO POWERLOAD system or a claim that the line never needs to be replaced and rewound.

One battery connects the package, and limits both jobs

The 2.0 Ah pack moves between the blower and trimmer; it does not power both tools simultaneously. Plan to trim, swap the pack to the blower, and finish the cleanup. The product page says “up to 30 minutes” of runtime without providing a separate schedule for using both tools or a matched workload guarantee. Treat that as a broad manufacturer claim, not thirty minutes of trimming followed by thirty minutes of blowing. High trigger settings and dense vegetation can use charge more quickly than light trimming or pavement cleanup.

Greenworks says the included 40V battery works with more than 75 of its 40V tools, which can make this a more sensible purchase if you want to build that battery family. It is not a Greenworks 60V pack, and voltage families should not be treated as interchangeable. The product listing describes the kit as appropriate for yards up to one-third acre; that is manufacturer sizing guidance, not a prediction for a property with long borders, steep slopes, heavy wet leaves, or repeated growth. If the blower is the only tool you need, a blower-only kit may avoid buying and storing a second machine. If a higher CFM floor is essential, the STBA40B210 stops at 390 CFM: a 391 CFM minimum excludes it, while the EGO ST1502LB combo publishes 530 CFM and pairs a larger 15-inch trimmer.

Where the trimmer fits—and where it does not

A 12-inch path is a narrower pass than the 15-inch trimmers in several EGO combo kits. That can be a reasonable scale for edging a small lawn and reaching around beds, but it also means more overlap when you want to cut a broad strip quickly. The 0.065-inch line is the manufacturer’s specified consumable; the manual warns against installing a heavier diameter. The exact listing says the trimmer is not attachment-capable. Do not buy it expecting to connect a hedge, brush or pole-saw accessory, and do not infer adjustability or an extended shaft from the assembly coupler shown in the instructions. A firm attachment-capability or telescoping-shaft requirement points elsewhere.

The manual describes battery removal before service, cleaning or storage and requires the guard to stay in place. It also warns to keep bystanders at least 50 feet away and not to use the equipment in rain. Those instructions apply to the included tools and are worth reading before assembling the shaft or replacing line. The product page lists a three-year tool warranty and three-year battery warranty, subject to the manufacturer’s conditions.

Controls and unknowns that should change the shortlist

The blower’s variable-speed trigger helps reduce airflow around gravel and planting beds; its top rating is still only a starting point for deciding whether it fits your yard. The page explicitly says the included trimmer is not attachment-capable and the motors are not brushless, but it does not give a precise ready-to-use weight for both tools or a numeric 50-foot sound rating. The component blower manual gives 4.45 pounds before battery and charger; that is not the complete kit’s working weight. Nor does the reviewed source bundle give a numerical blowing-force rating. If those limits are essential, leave them as unknown rather than counting the battery/tool combination as a confirmed pass.

The photo on Greenworks’ product page shows the two tools with a single battery and charger. It is useful for understanding the package, but the visible parts do not mean both tools run together. The manual links on the kit page are for the component trimmer and blower; their printed component codes are not the STBA40B210 retail kit identity. The exact product page, not a neighboring Greenworks kit, establishes that SKU and included setup. Check the retailer’s listed model number before checkout because similar 40V combo names can hide different batteries or tools.

Who should choose STBA40B210?

Keep it on the shortlist if you need a battery trimmer and a blower together, prefer a single 40V 2.0 Ah starter pack, want automatic restart line feed, and can work with 390 CFM and a 12-inch trimming path. It is a poor fit if you only need a powerful blower, expect to use garden attachments, need a larger included battery, or have a hard requirement for a telescoping trimmer shaft, exact operating weight, sound ceiling, or airflow above 390 CFM. In those cases, compare the EGO combo kits or buy separate tools selected for the job rather than treating a two-tool carton as an automatic value.
