Zoom on the Atlas 73521
The Atlas 73521
The Atlas 73521 is a cordless backpack blower that is ideal for homeowners with homes with expansive outdoor areas (the kind that is more measured in acres than square feet), and for professionals who maintain several properties.
It features a maximum air speed of 190 MPH and a maximum air volume rating of 760 cubic feet per minute (CFM). These values mean that it should manage everyday yard leaves rather efficiently, but also have the power to handle denser material or small piles of heavier debris across lawns, patios, and garden paths.
With an 80V brushless motor, the 73521 functions as a cordless blower, offering freedom of movement. It comes with two 4.0Ah batteries, but can also run on a single battery if needed. With all the included batteries, the unit can run up to 60 minutes on a single charge.
The Atlas 73521 features customizable airflow through its variable speed settings and effortless speed maintenance with built-in cruise control.
Weighing 15 lbs without the two batteries and 24.4 lbs with them, this backpack unit sits on the user’s back, reducing the need to support the full weight with the arms during operation. Its throttle is located on the tube, which allows to keep the left hand free. The telescopic tube enables quick and easy adjustments: shortening for tight spaces and extending as needed.
The Atlas 73521's performance versus other blowers
The following charts are provided to give you an idea how the key specs of the Atlas 73521 compare with other cordless backpack leaf blowers.
- Weighing only 15 lbs as a bare tool, the Atlas 73521 is on the lighter side compared with many cordless backpack blowers in the 60 to 80V range. Should weight be a deciding factor, the Greenworks Pro BPB80L2510 is worth a look at just 9.4 lbs the bare tool.
- The Atlas 73521 expels air at speeds up to 190 MPH, showcasing typical air speed performance for battery-operated backpack blowers. If you wish to benefit from air expelled at the fastest possible speed, the Stihl BRA 600 and its 253 MPH could be an option to consider.
- With a maximum airflow of 760 CFM (cubic feet per minute), this model falls squarely within the average range for cordless backpack blowers with a comparable voltage. If air volume is important to you, the Senix BLBX6-M, with 950 CFM, could be in your good books.
- When fully charged, the 73521 offers up to 60 minutes of autonomy, which may be considered relatively short compared to similar cordless backpack units. To enjoy the best possible autonomy in this category, you could have a look at the Toro Revolution 66100 which offers up to 330 minutes of runtime.
- Runtime alone doesn’t always tell the full story because it depends heavily on battery capacity. Runtime efficiency can give a clearer picture by showing how much work you get per unit of battery power. The Atlas 73521 shows relatively low runtime efficiency, providing fewer minutes of operation for each unit of battery power. If you are focused on getting more use per charge, the Toro Revolution 66100 offers the highest runtime efficiency, at 0.28 minutes per Wh.
Price comparison
As you can see from these interactive charts, when compared to other 60-80V cordless backpack blowers, the Atlas 73521 is on the average side of the price range.
Therefore, this blower nicely fits in the expected budget for this kind of product.
