Stihl 064 ... highest power to weight of any big saw?

[046]

We've been hearing for years about how Stihl 064 is barely heavier than a MS460,
but nearly powerfully as MS660 and tough as nails .... Well it's true!

now that I've got all at the same time. Stihl 064, 066, MS660 and 046.
IMHO Stihl 064 has the highest power to weight ratio of any big saw?

some folks call 064 an in between saw. might as well step up to 066.
well I disagree, Stihl 064 is considerably lighter and is closer to MS460.

if you've got to block down a large trunk up high and need raw HP....
064 may have the highest power to weight available for any big saw.

does anyone know of any big chainsaw with a higher power to weight ratio?

A scale and a dyno, all else is just speculation!!!

 

[nmurph]

well, going by mfg hp specs and actual weights of both an 064 and a 7900, the 7900 is slightly more powerful per lb of weight. .462hp/lb vs .431hp/lb

Yup...a big bore 064...

The 064 is a Classic

I'm not sure about the highest power to weight, but it has to have one of the best. Count me in at the 064 Fan Club.

I don't use it too much anymore, but I love mine. It's been bumped around a lot, but it's pretty low mileage. This saw is like the 260 for me in that it is dead reliable....it ALWAYS starts in 3 pulls.
Of course, it pulls waaaaay better :good:

 

[nmurph]

stock saw the 7900 is tops (not sure if the 681 weighs the same as the 7900). non-stock, it just a matter of how much do you want to spend.

 

[046]

Domar 7900 is listed as 13.6lb, an 78.5 cc saw ... has anyone actually put one on a scale to confirm? PS-7900

we all know how reliable factory figures can be...

well, going by mfg hp specs and actual weights of both an 064 and a 7900, the 7900 is slightly more powerful per lb of weight. .462hp/lb vs .431hp/lb

 

[nmurph]

both saws were cleaned and emptied. scales have been checked against the PB postal scales at work. they are within a couple tenths of an ounce.

7900 and 064

7900 @6.3hp and 6.4 Kg (14.1) lbs - From KWF Online. .447HP/lb. I think this is pretty close to what mine weighed when I got it, a little over 14 lbs.


064 @ 6.5hp and 7.1 Kg (15.6 lbs) from Stihl. .417HP/lb. Mine is the wrap model, so it is probably a bit heavier than this. I am too lazy to weigh it.....


Even in the best case, the 7900 has the 064 beat for hp to weight....torque is probably a different story given the displacement difference.

I was waiting to read how many posts it would take for someone to chime in with the 7900. Also the best bang for the buck too. Got mine brand spankin' new for $680 out the door. Not going to find that with any big stihls. The 064 is a better looker in my mind though. But my wallet and my grin sure love the Dolmar!

that KWF weight must be without the clutch cover. i have four 7900's and they all weigh the same.

 

[Brian VT]

I want a 7900 really bad, and my dealer has one he would give me a deal on, but I just can't justify it for firewood.
Anything that I'd need the 7900 for would be too much work to move and split.
I pass when I'm offered those big stems any more, unless I can just have some fun cutting it up and leave it there. lol

 

[046]

thanks for the actual weights nmurph!!!!

7900 14lb 10oz actual vs factory spec's are subject to fudge factor.

did anyone else notice the number times Stihl 064 got mentioned in the most durable saw thread? http://www.arboristsite.com/chainsaw/162228.htm

check those scales again; the 7900 is 14lb 10oz, the 064 is 15lb 4oz., and no, the 7900 noses the 064 out for P2W.

I don't mind the big stuff, any of the decent logs go to my mill, and the low quality, big stuff i cut into stove lengths then "noodle" it into small enough chunks to lift. I usually bring 2 saws anyway, a little limber- say my trusty 346, and grab a big boy like an 066 or 394.

I'm going to have to measure my 7900 again. I didn't think it came out to 14 lbs 10. Could the BB weigh a bit more? My scale is older and probably less accurate than yours!

Both saws are awesome. The 064 is a classic, and the 7900 is certain to be.....

 

[046]

oppsss... give me a bit... will be pulling out my scales soon.

here's a few listed spec's

---------------------

someone weight 064 and 046

14.6 vs. 14.9 pds. ca. 78 vs 85 cc

And you can put a 066 top end on the 064, or a less quality 066 BB......to get into the 90cc range

P.S. my 60cc 036 is lighter than my 51cc 028S, and that super is 11.8 pds, what 60cc boat anchor are you running?

P.P.S. I still like my old Homie Super XL it's a heavy but torquey 60cc beast with no AV, but will stump a 24" bar that the new revvers can't handle

BrianVT, that's how you justify a 7900! You can buck them and then noodle them into smaller chunks in short order with a big saw! My 75 year old Dad was sweating how he was going to split some 34+ inch rounds of pin oak he dropped on his property when I pulled out the Dolmar and sliced 'em up in short order into easy to handle chunks. I think he was impressed(you can't do that easily with a smaller saw like his 025).
He still asked me to try to noodle a little staighter as the splits were coming out a little too angled for his liking for stacking. (These retirees can get a wee bit anal ya know!)

 

[046]

blsnelling says 064 is only 5oz more than 046 ... that sounds about right last time I weight the saws.

They only weigh 5 oz more than a 046. Hard to beat that.

[blsnelling]

An 064 only weighs 5 oz more than a 046. As far as the 7900 is concerned, can you bolt a 93 or 99cc topend on it? Didn't think so Is there a factory bolt on unlimited coil available for your saw? Nope? Are dealers around the corner anywhere in America? Nope again. I'll take the 064. 99cc right here, baby!
