Husqvarna 570BTS Gas Backpack Blower
Professional users who want 37 newtons of blow force from a Husqvarna gas backpack blower and can source the 89-octane fuel Husqvarna asks for.
A 65.6cc two-stroke backpack blower Husqvarna gives at 37 newtons of blow force, 768 cfm and 236 mph at the round nozzle, with a 2.2 litre tank at 24.7 lb. The listing adds a pro-grade air filter, LowVib and an adjustable offset soft-grip handle.

Fit and limits
Strengths
- Blow force of 37 N and 236 mph at the round nozzle are stated identically on the listing and in Husqvarna's own specification table.
- Husqvarna publishes an equivalent handle vibration of 1.8 metres per second squared for this model, alongside its sound and emission figures.
- Husqvarna publishes a full specification table plus fuel, weight and run-time answers for this exact part number.
Caveats
- Husqvarna publishes two air-flow figures for this model on two of its own pages, 768 cfm at the nozzle and 972 CFM with no measuring point.
- The listing attaches no operator's manual, only the warranty document, so the manual must be obtained separately before first use.
- Sound pressure is 103 dB(A) at the operator's ear, and the fuel Husqvarna asks for is at least 89 octane and preferably ethanol-free.
A commercial backpack blower, and no manual in the listing
The 570BTS is sold under Husqvarna part number 966 62 94-02, the same number in the listing's details table, and Husqvarna's specification header describes it as a 65.6cc backpack blower. Its equipment lines give a round nozzle and an integrated harness and state that no vacuum kit is included.
The listing calls it a commercial-grade blower for professional use, with a pro-grade air filter, a load-reducing harness with wide shoulder straps, an adjustable offset soft-grip handle, LowVib, an air purge and a multi-speed throttle with cruise control.
One thing this listing does not include is an operator's manual. The only PDF attached to it is Husqvarna's Limited Warranty, so ask Husqvarna or the seller for the 570BTS manual before first use, and check the model on its cover against the plate on the machine.
768 cfm and 972 CFM are both Husqvarna numbers
The listing leads with 972 CFM alongside 236 MPH and 37 newtons of blow force, in its title and its bullets. Husqvarna's specification table for this part number gives max blow force 37 N and max air speed with the round nozzle 236 mph, which match, and max air flow at nozzle, round, as 768 cfm, which does not.
Husqvarna's FAQ on the 570BTS page itself repeats 768 CFM, so the product page is internally consistent. A FAQ answer published on Husqvarna's 580BTS page, describing this same model, instead says the 570BTS produces 972 CFM. Husqvarna has published both figures about one machine on two of its own pages.
The 570BTS specification table states its 768 cfm at the round nozzle; neither the listing's 972 CFM nor the 580BTS page's 972 CFM gives a measuring point. Husqvarna does not explain the difference on either page, so the gap cannot be closed from what is published. Ask Husqvarna which figure applies if air volume matters to your decision.
Engine and fuel, including the octane Husqvarna asks for
Husqvarna's engine block gives cylinder displacement of 65.6 cubic centimetres, output shaft power of 4 horsepower as net power to ISO 8893, a fuel tank of 74.4 US fluid ounces or 2.2 litres, fuel consumption of 431 grams per kilowatt hour, maximum power speed of 8,000 rpm, idling speed of 2,000 rpm and an electrode gap of 0.03 inches. Exhaust CO2 on the footnoted EU V laboratory cycle is 680 grams per kilowatt hour.
Fuel guidance for this model is specific. Husqvarna's FAQ calls for a 50:1 fuel-to-oil mix using fresh unleaded gasoline with a minimum octane rating of 89, and says ethanol-free fuel is highly recommended. Check that fuel meeting that description is available to you before you buy.
On endurance, Husqvarna's FAQ says the 2.2 litre tank gives more than an hour of continuous running under heavy load while noting that real run times vary with how much throttle you use. Treat that as the maker's own estimate rather than a measured figure, because the page does not say how it was produced.
Weight, size and the noise you will actually stand behind
Husqvarna gives a weight of 24.7 pounds in both its dimensions block and its FAQ; the listing says 24.5 pounds. Product size is 19.65 inches high, 12.8 inches long and 19.37 inches wide with a tube 2.8 inches in diameter and 47.126 inches long, and the listing's 19.37 by 12.8 by 19.65 inches is the same box written in a different order.
Sound is where the two documents separate sharply. Husqvarna gives a sound pressure level at the operator's ear of 103 dB(A), a measured sound power level of 110 dB(A) and a guaranteed sound power level, LWA, of 110 dB(A). The listing's Noise Level field reads 71 dB, which is not a figure Husqvarna publishes for this model.
Husqvarna gives equivalent vibration at the handle of 1.8 metres per second squared. The accessories it lists beside the 570BTS are protective glasses, technical work gloves and headband hearing protection; the protective-equipment requirements themselves belong to the operator's manual, which is not attached to this listing.
What the warranty document actually promises
The listing's description says the machine is backed by a two-year limited manufacturer's warranty for professional use. The PDF attached to the listing is Husqvarna's Limited Warranty, 2026 edition; its duration chart could not be read reliably, so this page does not confirm the two-year term from Husqvarna, but the document's prose sets the conditions.
Cover runs to the original retail purchaser from the date of retail purchase, and Husqvarna will repair or replace a defective product or part at its option, free of charge, at an authorised Servicing Dealer or Center using original manufacturer parts. Proof of purchase with date, model and serial number must be presented, and the cost of getting the machine to that dealer is the owner's.
The exclusions are specific. Normal wear parts such as air filters, spark plugs, fuel filters and starter cords are not covered, emissions components fall under a separate emission control warranty carried in the operator's manual packet, and failure to perform prescribed maintenance voids the warranty. Husqvarna also approves a maximum of 10 percent ethanol, states that E15 and E85 are not approved and that damage from them is not covered, excludes damage from old or stale fuel and from starting fluids, and sets a 90-day warranty period for rental use of any handheld product.
What is settled and what is not
Two figures on this listing are not settled by Husqvarna's documents: the 972 CFM headline, which Husqvarna's 570BTS page gives as 768 cfm at the nozzle while its 580BTS page repeats 972, and the 71 dB noise field, against Husqvarna's 103 dB(A) at the operator's ear.
Three things agree across the listing and Husqvarna's page: 37 newtons of blow force, 236 mph of air speed at the round nozzle, and dimensions of 19.37 by 12.8 by 19.65 inches. Weight is close but not identical, at 24.7 pounds from Husqvarna and 24.5 pounds on the listing.
The practical preparation is short. Get the operator's manual from Husqvarna or the seller, confirm you can buy fuel of at least 89 octane with ethanol-free preferred, and plan on two-stroke oil for a 50:1 mix. The listing supplies no manual, so the safety and starting instructions have to come from that document.
