Husqvarna 570BFS Backpack Blower review

Same published 570 output, with the throttle on the frame

The Husqvarna 570BFS is the frame-control sibling in the 570 gas backpack family. The exact U.S. product page identifies article 966 62 95-01 and lists a 65.6 cc two-stroke engine, 4 hp, an integrated harness, round nozzle and 2.2 L tank. Its product table gives 37 N maximum blowing force, 768 CFM at the pipe (972 CFM in the housing) and 236 mph with the standard nozzle. These are manufacturer maxima, not test results or a guaranteed clearing rate on every surface.

The useful difference is where the operator adjusts speed: the BFS throttle is mounted on the left side of the backpack frame, while the 570BTS uses a right-hand control on the blower tube. The shared manual documents the difference and gives the same standard-nozzle force, air volume and velocity for both models. The 570BFS is therefore not the “more powerful” version of the pair. It is a different control layout for someone who prefers a frame-mounted throttle. The exact handle and harness fit should be checked in person where possible; published output figures cannot tell you which control position feels natural.

Interpreting its conflicting weight descriptions

Weight is particularly easy to misstate on this model. The current product page's FAQ says 24.47 lb “when empty,” while the shared manual lists 24.9 lb in a technical table labeled simply “weight.” These values do not align exactly and the manual does not identify a fuel basis. The product FAQ wording also does not define every component included in “empty.” Keep both observations distinct: a page FAQ figure with an “empty” qualifier, and a manual value without a stated basis. Neither is a confirmed fueled operating weight, and the page language should not be silently rewritten as “bare tool.” The 2.2 L fuel tank adds weight in use.

The integrated harness is meant to support the backpack arrangement, but it does not make a heavy engine disappear. This is best evaluated as a full-sized backpack system, including the fuel routine and fit of the shoulder, chest and waist adjustments. If a hard mass ceiling is essential, the available data may not verify it. A shopper who cannot accept that uncertainty should not convert a similar-looking 570BTS number into a BFS bare-tool specification.

Fuel, use and package limits

Like the BTS, the BFS is a two-stroke gasoline blower. Husqvarna's shared manual specifies a 50:1 gasoline/oil mix, minimum 87 AKI gasoline, less than 10% ethanol and no more than a 30-day quantity of premixed fuel. It starts through an air-purge bulb, a start button and recoil pull. The start button is not an electric starter. Plan for mixing and storing fuel, pull-starting, filter care and engine service rather than treating this as a battery blower with a different label.

The assessed configuration includes a round nozzle and backpack harness and is blower-only. It does not vacuum leaves into a bag or mulch them. A flat nozzle is an optional attachment, not an included function in this plan; check the package if the accessory is important. The manual requires appropriate eye and hearing protection and a 15 m separation from people and animals. That operating envelope can be a poor fit for close neighbors, noise-sensitive use or short sessions where a lighter electric tool is more practical.

What other answers change

A gas-and-backpack selection matches the physical arrangement on paper, but this exact profile remains reference-only because model-specific safety eligibility has not been established. It is neither a recall finding nor a clearance. The finder will not recommend it for purchase, and a gas-only essential requirement can legitimately return no buying-eligible result. If power source is flexible and a battery backpack is acceptable, the EGO LB6000 is a separately reviewed 600 CFM body-only option; it is not an equivalent 37 N gas tool and requires a compatible battery and charger bought separately.

If weight is the main concern, a 25 lb bare-tool limit does not become satisfied by the BFS page's “when empty” FAQ. The manual's 24.9 lb basis is also unspecified. Unknown weight basis is not a pass. If collecting leaves is essential, use a real collection-capable configuration instead of a blower-only backpack. The EGO LV5000/LV5005, for example, are assessed vacuum/mulcher tools with a separate collection mode and 40 L bag; they are different handheld operating plans rather than attachments for the 570BFS.

Official source trail

Identity, article number, control placement and FAQ wording were inspected on Husqvarna's U.S. 570BFS product page and support page. Fuel and safety instructions and the shared technical table are in Husqvarna's 560BTS/570BTS/570BFS operator manual, revision 2507-002 dated 2025-02. It lists 24.9 lb for the BFS without specifying fuel basis.
