What is the point of a 70cc saw…

[davidwyby]

...when there are 80cc saws that weigh nearly the same Or less? (7900, 500i)

 

[Gullet]

You could prolly say that about all cc classes.

 

[bigbadbob]

There is no replacement for displacement!

After 10 or 15 years we will see if these saws are any good

Been pounding the chit out of my 500i, so far so good(1 year), although sometimes how lean the computer runs the saw concerns me

Fuel economy, required bar length, & other variables come before weight imo. If I can get by with 70cc's & a 20" b/c, I'm handier with the saw & there's less time that I have to spend sharpening. (see below) OTOH, I appreciate that a 500i sure makes life easier when you really need one.

In the PNW, a 372 or 461 can be a do-all saw that is a good chassis for a 24" bar, a 28" bar, a 32" bar, and for the XPW and 461 a 36" bar. My 390 feels porky compared to my 372, so if I need a 32" bar I'll grab the 372. Stihl's last 80cc saw was the 064 (which I haven't run), and if I have to carry them for any length of time the 066 is not gonna win out over a 461 unless I need those extra 15 cc's.

@pwheel I'm diggin that old economy power king

But but but a 70cc saw can’t pull that bar


Yeah I run 32” on 272. All the time. I’m hardwood. Stock.

I run old 272 because they’re powerful enough. Easy to work on myself. And cheap to buy.

Whats the point of anything but a piped 120cc saw?

 

[Duce]

Point of that is. Your done before you start. I like taking my time.

@Woodslasher 'member my 6100? Imagine if it was 80cc and light for it's ccs. :-D You need to run my 7900.

For the point of this thread (just generating some discussion) IMO, ccs translate more to how much bar length you can run vs. speed, unless the cc increase is so significant that you can run an 8 pin for speed. Testing by @Redbull661 and @TreeMonkey85 I think has shown not much increase in speed from larger rims, at least not in larger wood though.

I want as much power/bar length as I can carry for a significant amount of time, and for me that's a light 80cc...unless the trees are small of course.

I remember it was porky for a 60cc, does that count?

I'm not a fan of 8-pin rims, the few times I've tried them they just seemed like they killed the saw's grunt and made it slower instead of faster. I'll have to try one on an 056, though, as all the logger-used ones I've torn down had 3/8 x 8 rim on them, so they must've known something I don't.

 

[davidwyby]

Yeah, the 6100 must have been designed to run all day on a tank of gas and oil or something.

It's like running 4.10s and 39" tires on my '95 Cummins with a granny manual. you ain't gonna get away with that with a gasser. Gotta have stroke/grunt.

 

[Wood Doctor]

The 70 cc saw pulls a 25" bar without any trouble. Some 60 cc saws have a hard time. You add about a pound or so in weight. That's why I have three 70 cc saws and I use them for noodling big rounds. Sure, I could do this with my Stihl MS660, but I like using a lighter saw than that, such as my MS441 cm:

Hey, what’s the point of a 70cc saw if I can do what I need with a strong 50??

 

[Maintenance Chief]

Right tool for the job, if you run into enough 60"dbh codominate monsters 80cc isn't going to feel like its easy.
Just like fuel economy cutting firewood in the backyard is gonna be better with a good 40-50cc saw.
I have dropped alot of trees with a 70cc saw because the power was adequate for the dbh.

It’s a good saw… but it’s not perfect. The silly plastic oiler control bolt last me about 6 months logging before it starts loosing oil output. I can name a few other negatives but that’s just one.
