Price comparison

As you can see from these interactive charts, when compared to other gas backpack blowers, the Stihl BR 800 X MAGNUM® is on the expensive side of the price range.

4-Mix Engine Technology

Stihl's 4-Mix engine combines the advantages of 2-cycle and 4-cycle engines. This award-winning 4-stroke engine runs on a mix of gasoline and oil (1:50). For this to happen, the gasoline-oil mix enters the cylinder head through a bypass channel in order to offer full lubrication, which avoids the need for parts like an oil pump, sump or tank (which are compulsory for traditional 4-stroke engines). Therefore, there is no oil servicing to do (easy maintenance), the leaf blower is lighter (due to fewer parts) and its overall noise is lower. Additionally, all 4-MIX engines are fitted with a system that considerably reduces the effort needed to pull the starter rope.

The bottom line

STRENGTHS:
  • Cruise control
  • 4-Mix Engine
  • High CFM (912 CFM)
  • High MPH (239 MPH)
AVERAGE SPECS:
  • Decent weight (23 lbs)
  • Decent tank (67.6 fl. oz.)
  • Acceptable noise (78 dB)
WEAKNESSES:

    Bought mine in November. It’s March now it’s in the shop tore apart, waiting on parts maybe just get the runaround from customer support and tech. It never ran right right from the start. One run around after the other warranty is nonexistent would never buy another Stihl

    + PROS: If working properly a good product
    - CONS: No warranty no customer support and no tech support. They like to sell product just not back it if you get a lemon

    Not a great carburetor for cold Canadian winter usage. Maybe fine on milder climates. Moved a lot of snow when running at peak rpm but weather will affect the carburetor performance and rpm’s may drop while in use due to fuel mixture not quite right for -30°C or colder air temperatures. Have to retune the carburetor for different ambient temperatures which is irksome to maintain peak performance. Only used it in the winter following factory storage instructions for the summer. Carburetor likely works well in milder climates like I’m Germany and the USA but falters in performance in Canadian Winters when weather changes can be 20°C or more from one day to the next in the winter. Otherwise a nice machine the 800X.

    + PROS: Powerful with a nicely engineered nozzle extension with the locking twist nut.
    - CONS: Carb adjustment requirements, harness almost too small for bulky clothing and not friendly for mild arthritic condition of the user to install backpack blower on ones back.

    The weight of the blower is well distributed and being 2-3 pounds lighter than other similar backpacks means my wife or I can use it easily for an hour on several acres we maintain. It can blow 2″ gravel like its sand and deep leaves go 20 feet. We will never need to rake again. I didnt know about the 4 stroke until now, its very light and grunts, meaning you can set 20% throttle and tap the trigger when you need the boost. that makes it more quiet and not having the high pitch 2stroke whine. its VERY well thought out. it is thirstier than our 15hp mower per hour, but that means its even lighter, burning off the fuel. Im very very happy with ours. didnt have trouble starting it. It does use 89+ octane with mix, and it has a winter slide under the air filter that we will need to use if there is snow to blow. Again, @240mph, and 912cfm we will never touch a shovel again. it can lift an 8″ round, 2″ thick rock and move it away at full throttle. Stihl quality is worth the price. dont stop part of the way there. and it has residual value too if you sell your property.

    + PROS: even weight distribution and no pressure points with backpack. well engineered. didnt need ear muffs. 20' leaf blow flat, 25' downhill and 15' uphill with 25% grade. gets the job done fast and its fun to use. im done with the handheld, hand-numbing unit.
    - CONS: do need KN95 mask because it blows up a LOT of dust/etc... pretty thirsty fuel use, but its great HP.
