Overview of the Ryobi RY404170

The Ryobi RY404170 in use

The Ryobi RY404170

  • Power: The Ryobi RY404170 can force 730 cubic feet of air per minute (CFM) from its nozzle at a maximum speed of 165 MPH.
  • Power delivery: If you don’t like dealing with cords, you will be delighted to know that this blower is equipped with a brushless, battery-operated motor.
  • Battery: Its 6 Ah 40 V Li-ion battery (2 OP40604 batteries included) means that a user can operate the RY404170 for an estimated 40 minutes on a full charge.
  • Handling: By design, this model isn’t the smallest leaf blower on the market. It’s meant to be carried as a backpack so that the bulk of the unit is out of the way and the user’s hands are free to manipulate the nozzle. Its throttle is located on the tube, which allows you to keep your left hand free. Be aware that, at 29.2 lbs, the Ryobi RY404170 is on the heavier side of electric backpack blowers.
  • Speed Settings: To provide more control over their job to the user, the unit has a variable speed control setting. No matter the size of the job, the user can adjust the airflow of the Ryobi RY404170 to match it. On top of that, maintaining the selected speed is effortless, as it also features cruise control.
  • Noise: Its noise rating of 59 dB can be considered the standard for similar electric backpack blowers.

The Ryobi RY404170's performance versus other blowers

The following charts are provided to give you an idea how the key specs of the Ryobi RY404170 compare with backpack leaf blowers of similar voltage (between 36 and 40V).

  • Forced air leaving this blower’s nozzle has been clocked at 165 MPH. That makes the RY404170 average in terms of air speed for battery-operated backpack blowers between 36 and 40V. If you wish to benefit from air expelled at the fastest possible speed, the Echo DPB-5800T and its 195 MPH could be an option to consider.
  • If air volume is an important feature, the RY404170 by Ryobi will not disappoint. Its airflow maxes out at 730 CFM (cubic feet per minute), which makes this unit one of the most powerful cordless backpack blowers with a comparable voltage.
  • Autonomy-wise, with up to 40 minutes of autonomy on a full charge, the RY404170 is on the low end when compared with other cordless backpack units of similar voltage. To enjoy the best possible autonomy in this category, you could have a look at the Makita CBU02Z which offers up to 240 minutes of runtime.
