Overview of the Ryobi RY08420A

The Ryobi RY08420A in use

The Ryobi RY08420A

  • Power: The Ryobi RY08420A is a gas-powered leaf blower. It sports a max air speed of 185 MPH and a max air volume rating of 510 cubic feet per minute (CFM).
  • Handling: As this unit is a backpack leaf blower, the majority of the unit is distributed so that the user can operate it with ease for most reasonable periods of use. Its throttle is located on the tube, which allows you to keep your left hand free. Among other gas-powered backpack blowers, the Ryobi RY08420A can be considered light, weighing only 18 lbs.
  • Engine: The engine boasts a displacement of 42 cc. Since this is a 2-stroke engine, it’s important to remember that the RY08420A cannot run on gasoline alone. The fuel must be mixed with an appropriate ratio of gasoline and oil in order for it to function properly (for this Ryobi model, this ratio is 50:1).
  • Speed Settings: There are times when you only need a little more power, while other times you will want a bit more precision when clearing leaves and debris. For this purpose, the RY08420A offers variable speed settings, adding you, the user, more control, and a cruise control mode, which will allow you to maintain it comfortably for as long as you wish.
  • Noise: As far as gas-powered backpack blowers go, this one is average in terms of noise with a rating of 73.4 dB.
  • Fuel Tank: The fuel tank has a capacity of 38 fl. oz. Although this is not especially impressive for a backpack blower, it allows the unit to maintain a decent overall weight, making it more portable and comfortable to use.

  • Its max air volume rating (510 cubic feet per minute) means it is really not the biggest air producer of gas-powered backpack blowers. For the highest air volume, you may want to have a look at the Echo PB-9010T, which boasts with 1110 CFM.
