So take this for what its worth but I believe there is ton of misinformation in this thread. I own a tree service and Chainsaw mill tons of  big logs with twin Stihl 660's and a Cannon double ended bar.

I have been too busy to reply to this thread until now. I don't know how to make this fancy with quoting the right people so I will cut and paste....

T A Derrickson said....No difference in time/ease in running two  powerheads vs one with a helper handle on the far end.

My Findings....I Believe this to be completely wrong. How can double the HP not have any effect on cut speed? The truth is it does speed up the cut. More power means faster cutting assuming all other variable are the same.....


offrink Said.The biggest problem I see with the csms running a double power head is what if you dont make it through on a single tank of fuel.

My findings..Both saw face up... There is no issue....



Wal Nut heard......What I'm finding out is that the double powerheads really don't offer much in the way of additional power, the second powerhead only takes up the slack. This is right from Granberg, and it really changes my thoughts on this setup as I did want to run 2 powerheads, hoping to drastically reduce my time per cut in longer/wider logs

My finding....Back to HP again... This statement is completely wrong and I have no idea why a big company would tell you this... Its like saying a car with half the hp will run the same quarter mile time as one with double.  The second saw isn't just taking up the slack...It is working just as hard as the other...


I video my cuts so I can check times so I know what cuts fast and what doesn't. I would only use one head if it was just as fast but it is not!

There is other things in this thread that I have not tested personally so I will not comment on.
Shelby, thank you. I'm not here to post misinformation as I'm sure you're aware, just passing along what the mfg's are telling me. I have zero real-world experience with the double powerheads, and it's disheartening to hear you say you've got plenty of experience showing otherwise, as I just ordered my setup yesterday. I CAN run double heads on it but will lose more capacity with 2 vs 1 head which isn't what I wanted to do, and ordered the bar length based on 1 powerhead. 
Thanks for contributing to this thread. If you have any videos showing the 2 vs 1 head, it would be nice to see.

Thanks! How much bar length are you losing running a double power head?

You are not going to loose bar length with twin heads. Just take the dogs off the saw.... I wonder why my Helper handle looks brand new...

This is assuming a stihl 660/066 or smaller is being used. You may loose bar length with 880's..

i thought about both saws being right side up.

It makes sense that both would be right side up. One faces the direction you are going and the other faces the direction you came from.
There are a lot of Old Loggers.
There are a lot of Bold Loggers.
But there ain't a lot of Old, Bold Loggers!
