Your needs, this model
Does it fit your priorities?
Can I require a trimmer in the kit, a tapered nozzle and at least 615 CFM?
Yes. ST6151LB includes a 15-inch trimmer, its blower manual lists a tapered nozzle, and the maximum is 615 CFM. These are published package/manual facts, not a measured clearing-time guarantee.
Explore this need in the finder →Does the included 2.5 Ah battery meet a firm 2.5 Ah-per-pack minimum for both tools?
The exact kit page lists one 2.5 Ah battery and the two tools share the compatible pack; one battery cannot power both at the same time. Runtime depends on mode and task.
Explore this need in the finder →Can it meet both a 615 CFM and 18.5 N minimum while keeping the blower body below 4.75 lb?
The LB6150 manual lists 615 CFM, 18.5 N and a 4.74 lb body-only weight. The battery-installed weight remains unknown, so this is not a complete carried-weight limit.

The EGO ST6151LB is not simply a blower with a trimmer tossed into the title: it is a specific 56V package containing a 615 CFM handheld blower, a 15-inch string trimmer, one 2.5 Ah battery and a standard charger. That makes it most interesting to someone setting up both jobs on the EGO battery platform. If you already own a trimmer and only need to clear clippings, the separate LB6151 blower kit is the cleaner comparison; this combo asks you to value the second tool as well as the blower.
The trimmer’s shaft telescopes, and the current kit page describes POWERLOAD line winding, .095-inch dual spiral-twist line and a 15-inch cutting swath. The included blower is a variable-speed handheld rather than a backpack model. EGO lists IPX4 weather resistance for the kit, but that is not permission to leave the tools or battery out in rain. Its stated five-year limited tool and three-year limited battery warranties have conditions, so read the current terms before relying on them.
What the blower numbers mean in practice
The LB6150-family manual lists a maximum of 615 CFM, 18.5 newtons of blowing force and 170 mph with the tapered nozzle attached; it lists 150 mph without that tapered nozzle. This combo supplies the tapered nozzle, not a spread nozzle. A spread nozzle appears in the manual’s recommended-accessories list, so a buyer who needs that wider attachment in the box should look elsewhere or budget for the separate accessory. The speed dial covers a lower 200–480 CFM range, while the boost button calls up the 615 CFM maximum. That combination can be more useful than leaving the blower on full output: gentler air is easier to direct away from gravel and beds, with boost available for a tougher patch.
Those figures are published maxima, not a comparison test or a guarantee about how fast a specific driveway clears. Leaves can be dry, damp, matted or mixed with twigs; the nozzle and surface change the result. The manual’s 4.74-pound figure is for the blower without its battery. EGO does not give a complete carry weight for this exact kit with its battery and nozzle, so do not treat the bare-body number as the load you will hold.
One 2.5 Ah battery, two tools
The box includes one 2.5 Ah ARC Lithium battery and a standard charger. The same pack can power either EGO tool, but it cannot run both at once. EGO advertises up to 75 minutes for the blower and up to 45 minutes for the trimmer with the included battery. The linked LB6150 blower manual instead gives approximate runtime figures of 100 minutes on low, 15 on high and 10 in boost; its ST1510T trimmer manual describes its own operating conditions. These are manufacturer statements for different modes and references, not a promise of uninterrupted time for a mixed yard routine. A long trimming session followed by boost-heavy clearing may require a spare compatible battery or a pause to recharge.
The exact package page calls the trimmer POWERLOAD. The linked trimmer manual identifies the ST1510T family and describes a bump-feed head, .095-inch twisted line and a 15-inch cutting width. Those descriptions cover different parts of line handling: powered winding is for replacing line, while bump feed advances line during use. Still, the manual is for the component family rather than a separate ST6151LB kit manual; check the delivered contents and instructions if a particular head mechanism is essential to your purchase.
Who should choose it—and who should not
This kit suits a homeowner who wants to edge or trim and then clear the same area with two cordless tools, prefers a simple single-battery package and has use for the included tapered nozzle. The trimmer shaft adjustment may help different users find a comfortable length, while the blower’s dial and lock-on control reduce the need to hold one trigger position continuously. It is a more coherent purchase when both jobs are real needs rather than an accidental bundle discount.
It is less compelling if you already own a compatible trimmer, need a wider blower nozzle, or expect long high-output sessions on a single small battery. Its 615 CFM ceiling is below the ST6703LB’s 670 CFM. The latter includes a larger 4.0 Ah battery, a 210 W charger and both tapered and spread blower nozzles, but it is a larger kit rather than an automatic upgrade for every yard. If the trimmer is not wanted, compare the standalone LB6151 kit for the same general blower class without buying a second tool. If a 4 Ah pack and both nozzle shapes matter, compare the ST6703LB review and verify the exact kit suffix.
Bottom line
Choose the ST6151LB for the actual combination: a 615 CFM handheld blower, a telescoping 15-inch trimmer and one 2.5 Ah battery/standard-charger setup. It is not a substitute for a backpack blower or a larger-capacity battery kit, and its published CFM, runtime and weight numbers each describe different conditions. Before ordering, confirm the package says ST6151LB, check whether the tapered-only blower nozzle is enough for your surfaces, and decide whether one battery covers the trimming and cleanup sequence you expect.
