A really powerful machine. It has the same engine as the 420 model, which is a hefty 56.5 cc power unit. It gives out more than 3 1/2 horsepower and this is put to good use in creating a blower air speed of 181 MPH with a volume of air moved of 465 CFM. These measurements are made at the end of the tube which means that this is exactly what hits the leaves when you pont the tool at them. The major difference between this blower and the 420 is that it has a littler tube size. This has the effect of making a quicker air speed.
This faster air velocity means that it can break up clumps of leaves and then the 465 CFM keeps them moving. It doesn't matter if the leaves are wet or dry this blower shifts them all the same. As well as leaves this machine is perfect for blowing grass cuttings. It can easily blow large heaps of fresh grass cuttings even if they are damp.
It is a seriously high quality machine which should last a long time. The two stroke engine is manufactured with dual piston rings, chrome lined cylinder bore and a forged crank shaft. These all help to provide it with a long service life. It is also made to be simply and quickly serviced.
The machine has a translucent fuel tank so that the level can easily be seen. The tank can contain one and a half liters of fuel. This is mixed to the usual 50:1 gas to oil mixture ratio for 2 stroke engines. A full tank will give approximately ninety minutes of blowing time, even if the machine is run at full throttle. Compared with other smaller engine models it could be thought of as being a bit of a gas guzzler. Even so the engine has reduced emissions compared to earlier models.
The BR380 Stihl backpack blower is moderately easy to start. When cold it can need four to 5 pulls and when warm 1 to two pulls. There is no primer for the engine and this may explain the extra pulls needed. Once going it runs very smoothly and accelerates rapidly without delay, even when cold. Considering its capability it is moderately quiet creating a noise level of 73db. You can get a vacuum kit and a spray conversion kit to make this blower even more versatile.
In terms of ergonomics the straps and back pad are very comfortable and it is quite easy to put on. The blower weighs just over 20lb which means that it can get to feel a little heavy after you have operated it for a time. The easy grip throttle is trigger operated and is positioned on a handle fixed to the down tube for easy getting to. There is also an on/off switch and cruise control which means that you can set the throttle you want to use and don't have to keep the trigger held all of the time. There is a built in top carry handle and tool holder. It can be a little awkward to use in restricted spaces. However in wide open areas it is very easy to use and very powerful.
If you are looking for a professional, powerful, comfortable and simple to use backpack leaf blower that gives you the most blow for your buck then this could be the one for you. It easily deals with grass clippings and light to moderate leaf clean up and is produced using quality parts which give it a long service life. Yes, you really need to feel the force of this one!
