we use the echo 650 b/p for snow cleaning in tight spots and when the snow is powdery like today. In only an inch or 2 of powder, it tends to want to pack the snow here and there even when letting off the throttle and trying to go more parallel at the snow.
Do they make a curved end that would be parallel to the ground? If so, have you used it and how did it work for you?

thanks

They don't Gary, but Stihl 400's uses them. Find a Stihl dealer. I used them on ALL my blowers. It's only like 12 bucks and makes a world of difference.

BTW, all you need is a 3 inch automotive hose clamp to attach it. The curved end is especially great for cleaning out leaves from pacysandra, flower beds, etc.

thanks ROd...I assume theres no significant more load on the engine or you wouldn't be risking that right?

i asked my dealer about the curved tips for my 750 (same as the 650) and he said that it restricts airflow and can cause the cavitation as well as engine problems after pro-longed use.

Have you tried a Push Blower on snow?

We use the 750's for steps & landings & the push blowers for drives in Light Powder.

Gary

There is no restriction of airflow. All you are doing is redirecting the airflow a different way. I've been using curved ends on my bp's for years now with absolutely no engine overload or premature failure in any of our Echo's or Remaxes. BTW, it's the Stihl BR400 that uses them. Go for it...

Yea, I feel sorry for all of em Gary...NOT! Only thing I'm sorry about is only adding one plow truck this winter instead of two.

Yep metoo, I'm liking Monday and Tuesday's forecast. Gonna be a double hit and billing I think...and it's still January...CHA-CHING:D

Not entirely true. By redirecting you are restricting which according to Echo will cause you engine problems over the long haul. This is especially true w/ the new High Output Blowers.

You can get a curved end from Mayberrys.com. Scroll down the the 650 and 750 and you will see it.

Only the 400 series Echo's have the curved end in your link.

thanks for the link Auburn...

Fareway..just a question
I'm clueless as far as engineering/design stuff as it pertains to equipment so please bear with me on this question.

Lets say we want to blow away a 2 foot pile of wet, packed leaves with the standard stright end tube. In using the 650 to blow light snow, what I;ve noticed is becuase the blast of air is so strong, that it actually packs even light snow...and...it would seem, that the ground/snow pack is actually "pushing back" on the machine, thereby, resticting the flow of air through the unit. This is how most of us use these blowers....we work the guts out of them.
Now we add a curved end...air is flowing parallel with the ground after exiting the tube, thereby less resistance, thus the airflow is less restricted than if were pointed down at the ground.

I suppose the issue may be that the curve in the tube is where the resistance is but it would seem that that curve would not be much more strain than sticking the straight end of the tube near a pile of wet leaves....help me understand the issue... and thanks

You got it Gary...it isn't like you're squeezing the end of the tube either with a smaller sized tube opening. An example of that would be like a kid spraying a friend with a garden hose by holding his thumb partially over the opening and thus creating more of a jet stream of water...this isn't the case though.

The other thing is the curved end is a gentle curve, not a 180 degree or something.

hey ROd...so how much of the white stuff tue/wed are they calling for in your area? sounds like a big one right in your neck of the woods....damn filthy rich plowjockey...I'll bet you never even put your toes in the snow do you?...pop in a cd of Bon Joysee, a little java, shirt sleeves, and a pile of money at the end of the day...what a racket...and please dont say it today...I'm tired, cold, and wet...you can't relate to that I'm sure...

Close Gary...cd is usually like Sheryl Crow, 3 Doors Down, or Toby Keith, no java, I go the Diet Pepsi route, short sleeve shirt yes, and comfortable Nikes. Toes in the snow? No way Jose.

How much white stuff? Makes no diff to me...the meter will be a runnin' though!

You can direct the things you are blowing better. Your arm will hurt a little if you use it for the first time for an hour or more.
It kinda pushes backwards on the tube.
