That is Dolmar's big saw now. the PS9010 was discontinued. I have a customer that will put his PS-7900 with 24 up against anybody with a Stihl MS660 any day of the week.
The method he is probablly talking about is cutting the wedge out. Then before starting the back cut, plunge cutting up inside the wedge to get out the heartwood. And I dont like that either.
What mods has he done to the 7900?? Cause stock for stock.....there's no replacement for displacement. The 660 is no slouch. But it is also much bigger and heavier. Thats what makes the 7900 great. It isnt raw power, but power to weight ratio:thumbsup:
Yea that is a good video to sho the technique and how it is possible. And that technique is JUST fine for logging if that is the plan.
BUT....If you are just cutting it for firewood, you really need a bigger bar. Otherwise, how do you cut peices off for the first 20' of the log??
Here's a real good video of that technique, I found it interesting, but a longer bar would have been a lot faster.

Saw is 100% stock. I have done all the maintenance since I sold it. Do all of his chain sharpening. I have personally put this saw through a 20 inch seasoned red oak log in 8 seconds. I have also run the PS-9010/Solo 694, and this saw is three times faster than either one of them.
I have seen this saw cut 2 inches deep in the time it takes to think about taking your finger off the trigger. The only complained the customer has had with this saw over the last 5 years, and like 60 gallon of gas through it is "It cuts too fast".
