Greenworks BL40L510 40V 730 CFM blower kit review

A complete 40V kit with a high published airflow maximum

Greenworks identifies this exact package as model BL40L510, SKU 2427402: a 40V cordless leaf blower sold with one 5.0 Ah battery and a 5A charger. That package distinction is more useful than the headline CFM if you are starting without compatible Greenworks 40V equipment. You receive a pack and charger rather than having to source them separately. Confirm the exact kit contents with the seller before ordering; the manufacturer's written inclusion list names the blower, battery, charger and owner's manual.

What 730 CFM and 190 mph do—and do not—tell you

The product page publishes maximums of 730 CFM and 190 mph. It also describes a variable-speed dial, an adjustable airflow tip and a Turbo button. These figures describe the maker's stated output, not an independent yard test or a promise that every leaf pile, wet surface or debris type will move at the same rate. Greenworks says the machine is intended for yards up to one-half acre, but that is a broad recommendation rather than a runtime or clearing-time guarantee. Use the dial to vary output for the task; reserve the Turbo feature for moments that need extra airflow rather than assuming it is the normal setting.

Those controls suit someone who wants one blower for lighter sweeping and occasional tougher cleanup, while the 730-CFM number makes a useful upper-bound filter when comparing published specifications. It does not make this a vacuum. If the need is to pick up leaves into a bag or mulch them, select a model with an explicitly documented collection setup instead.

The kit is not the same thing as a runtime promise

The listed 5.0 Ah battery and 5A charger make the 2427402 package straightforward for a buyer who needs both. Greenworks advertises up to 60 minutes of runtime and a 60-minute recharge, but the page does not describe enough operating conditions to treat either number as guaranteed for a particular yard, battery age or use of Turbo. A higher-capacity pack, repeated high-output use, temperature and the task itself can change the time away from a charger. If long uninterrupted sessions are essential, check whether a compatible spare pack and charging plan fit your actual use; do not read the maximum-runtime line as a measured work session.

There is also a weight caveat worth keeping in view. Greenworks lists “Product Weight” at 5.5 lb, but the exact page does not say whether that figure includes the battery or define a bare-tool versus ready-to-use basis. It therefore cannot support a strict carry-weight limit. The feature copy calls the design lightweight, but that is not a substitute for a clearly based weight measurement. If balance or fatigue is a hard requirement, handle the assembled tool or obtain a written weight basis for this exact SKU before deciding.

Do not borrow specifications from the linked manual without resolving its identity

The product page links a Greenworks 40V blower manual whose PDF filename includes 2427402. The document's displayed cover and model references do not line up cleanly with BL40L510: the cover says BLF448 and its contents list BL40L8141. That is a real source-identity gap, not a reason to silently rename the retail model or transfer another model's attachment, weight or operating details. This review therefore relies on the exact BL40L510 product page for its published output, kit list and controls, and leaves manual-specific details such as precise assembly and safety wording for the seller or manufacturer to confirm against the manual for the unit being supplied. Follow the exact operator's manual before use.

Choose the function before comparing the number

BL40L510 is presented as a blower package, not a blower-vacuum kit. It fits a buyer who wants battery operation, an included 5 Ah battery and charger, and a published maximum of at least 730 CFM, while accepting that its actual weight basis and runtime conditions are not established. It is a poor match if leaf collection, mulching, a verified sub-5.5-lb working setup, a specific nozzle shape in the box, or a sound rating is essential: the exact page does not substantiate those requirements.

Compare it with Greenworks BL40L511 if you want a 40V package with a separate blower-vacuum function and one 5.0 Ah battery; the BL40L511 page publishes 505 CFM, so the trade is lower listed airflow for collection capability. The BL48L4420 is another collection-oriented Greenworks configuration, but it uses two 24V packs together in its 48V arrangement. If you only need blowing and already own compatible Greenworks 40V batteries, compare a tool-only package carefully; do not assume an 80V pack fits this 40V tool. The battery included here can be a benefit to a new 40V owner and unnecessary duplication to someone who already has a suitable kit.

Recall check and limits of this assessment

The Greenworks recall page and the CPSC leaf-blower index currently identify selected Kobalt-branded USB-C battery products; neither lists BL40L510 or SKU 2427402. That does not clear an individual battery by serial number or guarantee that no later notice will apply. Check current manufacturer notices and the label on the actual pack. Greenworks lists a three-year limited warranty for the tool and battery; read the warranty terms for the exact purchase and use.

Bottom line: BL40L510 / 2427402 is worth considering when a buyer wants a Greenworks 40V blower kit with one 5.0 Ah pack and a 5A charger, variable speed, Turbo and a 730-CFM published maximum. Its key limits are equally important: it is not listed as a vacuum/mulcher, 5.5 lb has no stated measurement basis, the 60-minute runtime is a manufacturer maximum without stated conditions, and the linked manual's model text does not bridge cleanly to BL40L510. This is a source-based assessment, not hands-on ownership or a performance test.
