  • Never do this to ANY leaf blower. If you do THIS to a leaf blower, BEWARE, this might happen to you!! Watch now to see what happens if you modify the blower tube. This is called an over speed seizure. An over speed seizure is when the crankshaft bearings spin faster than they were designed for. Let me show you what this means. It is extremely easy to avoid destroying your leaf blower in this manner. Watch now!

    Hi Steve, can I just say you have helped me no end in doing those little jobs in the service of my garden equipment. I just wanted to say that I have a stihl leaf blower and it came with a stihl restricted end to the main tube and I find that as you say it produces more blowing power and as a result I dont have to rev the engine as much so there's no need to over rev the motor at all. Less stress for the motor and not as much fuel used Just a thought.

It really moves material ...leaves, grass, snow if it is not wet and even twigs and small branches....it is possible to cut back on the amount of air and actually make piles of leaves or you can just blast them all the way off the property then grab a beverage

    Good point Steve. The last 2 Stihl BG86 C+E hand held blowers that I've purchased actually came with a restricted flow "flat" tube and the regular "round" one. I have never used the flat one but it is supposed to raise the exit speed from 154 to 190 MPH (at lower volume of course). I'm sure they designed the flat tube to still be within RPM maximum spec. I just never had a use for it. Supposedly good for cleaning driveways and peeling up wet leaves ETC. Great channel, glad I found it!

    • @900stx7
      @900stx7 Před 7 měsíci

      My Stihl came with two nozzles.
      The flat one has higher velocity with less volume, it's for flat surfaces like your drive way.
      The round, low velocity, high volume one is for your lawn.
      I find myself using the round one the most.

    It's simple fluid dynamics for those who think they're smarter than the engineers. Think of a pressure washer, a beast flows over 4 gpm's. Now picture that same 4 gpm flowing through a tube 5" in diameter, it would be just spilling out. CFM in a blower is the same, a narrower opening will give you higher wind speed but less volume (CFM) at the same rpm's. You'd have to increase RPM's to get the original CFM's. Great simple video and explanation. Thanks for taking the time.

    • @daleworden189

  • @KarlBunker
    @KarlBunker Před 3 lety +105

    Interesting. The same thing happens with any vacuum cleaner -- whenever something blocks the suction nozzle, you can hear the motor screaming as it goes faster. As I understand it, this actually happens because the motor (or blower engine) is doing _less_ work. It's not moving as much air, so there's less drag on the impeller, so the motor is free to spin faster.

    • @stellarproductions8888
      @stellarproductions8888 Před 3 lety +2

      Thats 100% correct. But you also have a problem with that. The motor wasn't designed to operate at that higher RPM for long, so what you are doing, is putting added wearing on the bearings, the stator, the rotor, and the brushes. Eventually something is gonna give, and they do, the motors die, and then your looking for a new vacuum cleaner.

    • @therandom906
      @therandom906 Před 3 lety

      The reason the motor picks up speed is because air is a fluid. Believe it or not. Air causes resistance on the fan blades and makes the motor run at a slower speed as its “under load”. If you remove the load to the motor, it can spin a lot faster. Roasting the motor. Try with your vacuum at home, take the hose off and cover the end. The vacuum motor will pick up speed as the load is removed. The load being air.

    What about the other way? Case in point, my stihl blower has a factory tapered fitting, however, I'd like to remove the tapered fitting and tubing to the length of my arm to have a short stubby blower for cleaning some of the hallways & metal framing I'm responsible for at work. Any adverse effect on the engines' internals by removing restriction?

    I’m been electrician, for 40+ years. I’ve seen many failures of electric equipment for the same reason. Water Pumps, blowers, vacuum pumps are all designed to run at specific flow rates and pressures. Tamper with these things, and you will overload a motor and possibly burn it out. For example, a submersible well pump must have back pressure to restrict the flow to the specified gallons per minute. A pump connected to an open tank, will pump almost double the rated gpm and will draw 50% more amps than rated. If the pump is dead headed, the amps will drop to about 1/2 the rating. But a dead headed pump will overheat very quickly, I’ve seen them actually boil the water and melt plastic pipe. They need the water flowing thru to cool the pump. So both scenarios, high flow/low flow will quickly destroy the pump.

      Since no one replied, let me try. Go by your ear. If you hear the motor change RPM then don't do that. Minor changes, I think would be expected. But your ear should tell you if the motor is stressed.

      @@HerminiePA was thinking the same thing. What I used was basically a downspout (2x3) and a couple 90* fittings to use with mine. It does not really change the volume of air going out much due to a very small difference in restriction.

    Steve, you have to tell them why this happens. The back pressure inside the tube causes the fan to cavitate which unloads the fan and allows the engine to run faster. Basically the fan is not grabbing air anymore but slipping on the air . You rock Steve. Keep up the good work.

    • @rossbrumby1957
      @rossbrumby1957 Před 3 lety +1

      Air props don't cavitate, from what I've read. Cavitation is a liquid prop problem, the closest similar issue aircraft props get is when blade tips get near supersonic and turbulence occurs. Drum fans in leaf blowers however, being not nearly as efficient, will actually have less load if over restricted because the air stays inside and rotates with the fan rather than forcing out a too small hole as Steve demonstrated. To make good pressure AND velocity, the blower would need to be built with the tolerances of a car's turbo and run at similar rpm.

    • @dedomv11
      @dedomv11 Před 3 lety

      I fly airplanes including a commercial instrument multi-engine licensing. I have cavitated propellers. Jet engines can also cavitate. You can feel a cavitation if you have a high enough angle of attack and then you can feel the airplane bite air again. Full cavitation could be seen when an airplane is going straight up and then it starts to fall back down tail first. At that point the propeller is in full cavitation.

    • @dedomv11
      @dedomv11 Před 3 lety

      When you go straight up with an airplane and there's not enough power for the airplane to go up the propeller eventually unloads because it can't grab the air hence slippage or cavitation. Especially on constant speed props you notice different loads on the engine. You can force the blade angle to go above its ability to grab air and cavitate the prop.

      You might be able to fix this issue by making your mixed gas a little bit heavier on the oil but don't quote me on that. Although I don't see why you would restrict the airflow in the first place.

      My Stihl blower came with two tubes. One has a oval shape to it and it does speed up the engine somewhat because the outlet is smaller than the round one. Since it came like that new it should be fine, but I noticed the rpm difference when I use the smaller outlet tube. I never use the oval small outlet tube because even though it revs higher, the airflow is not as useful for clearing leaves and grass clippings for me. I can see where this issue would be real bad if the carb was set a little lean to start with and someone restricted the outlet tube. It will rev itself to pieces.

      Hi Bob, iam not saying it's better idea. Iam just saying if you have ever used a blow gun some have holes in the side of the tube so theres a release for the air in case of blockage but it does increase the amount of air. If you have a older machine it might be a to get back the performance of new. And by the way it dosent increase the rpms because you are not restricting the tube .

      I run a gutter cleaning kit in my echo blowers all fall without any issues. I went with the echo kit recommended for my blower no problem. You should be able to tell if your running something that is too restrictive. Also as far as restrictive pipes go the revving is a symptom of the carb being adjusted for a less restrictive pipe you can always adjust your carb to run the way it’s supposed to with any attachment I guess the reason people don’t is they want it to rev out but in doing so you are really just letting the engine go outside it’s designed power band it is made to run at.

Turns out that piece of garbage wasn't able to handle the RPM cuz it was so cheap. Then I got my STIHL and I kept the default tube on. Lesson learned, thanks! 👍😁
