    I had a realization the other day as I was working my 372XP through a massive frozen oak log. That the excellent power to weight ratio of this saw meant nothing to me. I'm bucking logs and noodling the rounds into sections - and I spend 95% of the time with the weight of the saw on the log or supported by the felling spikes. I am fortunate that my shop is 75' from where I cut the logs - so no lugging it around in the woods.

    Once I get through these logs I expect the tree guys will still have large logs from time to time. (Not many people can do something useful with them)

    I'm really thinking hard about selling the 372XP and buying a 661 so that I can blast through these logs. That will leave me with my 261 and a 661. 261 for limbing and cleanup work, and a 661 for firewood work. Will I have buyers/sellers remorse?

    I've never owned a 90cc saw. The biggest one I've owned is my current Echo CS 680. My last saw was a Stihl Farm Boss and at 56.5 cc it got the job done. But with a hair over 67 cc this new saw is pretty slick with a 20 inch bar.

    My 70cc saw spends all of it's time with a 28" bar buried in wood. While the saw runs the 28 without issue, that doesn't mean it's ideal for the job. I guess that's the center of my thoughts.

    A 661 is a nice saw but I don't really think it will blow the socks off a 372 with a 28".

    Yes I think you will have sellers remorse. I do not believe you will notice a huge difference between a 70cc and 90cc unless you are consistently dealing with 36" of full comp buried to the hilt. In my opinion a 70cc is about perfect size for most fire wood duties. I use my 395 for bucking in the yard. I have my wife help me load logs onto the saw buck until it groans then fire the saw up and give it hell. I don't carry the saw around any more than I have to. That sucker is heavy.

    How big of a bar would get you through these logs in one swipe?

    But....If the OP is regularly cutting "massive" logs, wouldn't the 661 allow him to run a considerably longer bar? Agree that at 28" or under it shouldn't make much difference.

    I agree... If he needs a bigger bar? The 661 is the saw. (Plus, I know when I want something? I want encouragement. This is encouragement ;))

    After seeing how strong a 661 is against a ported 660 (with extra work) does? I'd say 661 all day.


    The difference in cut speed still may not be much, but if your looking for a bigger bar and faster cutting?

    661. . . :dex:

    661 and a 36" will be about the same cutting speed as a 372 and 28" I would guess. If you want to run a 42" then a 661 will do it better than a 660. A 395 would do it also.

    As long as the job gets done without having to call 911! That's what really matters.:thumbs:

    That would be over 4 feet. I'm not sure doing a single pass would help much. Making chips a lot faster would help. So far it doesn't sound like the extra power would save much time.

    4' wood I'd want a 32-36" bar ideally. I have a 50" that's going to be used occasionally on a 394 or maybe a 661 once to try it If one shows up for me to use.

    I have a 2100 cd that is 99cc's of saw. I use it on occasion but my 272 is where all the real work gets done.
    If I had to eliminate one of them the 2100 would go. It is just to heavy and it does make a difference after a couple of hours of cutting. Even when using my 272 with a 24" bar and I come across a big tree that needs to be cut down to size so I can load it, I just cut it from both sides.

    That was your imagination. Carry on.

    I will give you my opinion. You have already planted the 661 seed in your head, read about them, looked at them, NOW your posting about them asking questions, mine as well get it over with and put yourself out of misery, and go buy one!!

    There is no replacement for displacement,,, none,, the 661 is a great saw, with gobs of power!! With a 28" lite bar (of your choice) it is very well balanced saw. Even with a 36" lite bar they feel great!! A friend of mine and I cut wood a few weeks back, he has a 660 with a 28" regular weight bar, and used the 661 with the 28" lite bar and asked why it feels a pound to pound-1/2 lighter when it is not according to the specs, I told him it's the balance with the lite bar, that is what makes the saw!

    My 441 with a regular weight 28" bar, does not feel any lighter to me then the 661 with a 28" lite bar.

    My vote is 661! you will not have have buyers/sellers remorse :) :) let me know if I can give you any more encouragement?? I have pics & vids :)

    If it wasn't mtronic I would be more likely to get one.I don't quite trust it for milling. I've not run a stocker just a ported one. The 70cc saws are right with them with the shorter bars.

    I hear yah,, I like MT, some dont,, I guess they make a 661 non MT, for other markets outside the USA.

    I like my 441 with a 20" bar a LOT. With a 28" bar, not so much. It could be the dry wood I cut or the elevation, but the 28" bar on my 441 just does not suit me. I think I showed this on SH,, MM441c vs 661c, both with 28" bars and new full comp chain, dry crotch elm,

    the 661 was only on tank 3 here, it has woke up a LOT since, like a whole nuther saw,, you can hear it 4 stroking in the cut still in this video,

    watch the flow of chips coming out of the 441, it can do it, just have to be light handed, I just think the 661 does it better, IMHO,
