Bar length and cutting performance?

I'm picking up a new Dolmar 6100 tomorrow and selling my Husky 562XP.  I run 20" bars.   I'll be buying the Dolmar with a 20" bar.  However, the majority of the time I'm cutting 8 foot logs that I've had delivered and they don't tend to run super large diameters.  I like the 20" because it has a nice reach and when I have 4 or 5 logs on the forks on the skid steer its comfortable to reach out and cut the logs.  Weight isn't a problem for me.

Having said all that, would a 16" or 18" chain cut faster than a 20" chain?  Its been years since I've used a shorter bar but I seem to recall that they felt like they cut faster than a longer bar/chain combination.  I'm wondering if I should have a shorter bar for every day use and the longer bar for when I have larger stuff to cut?  Again...I don't care about the weight I care more about what's going to get through the logs faster.

Thanks!

  Cutting the same sized wood say 16" you wont see much difference between a 18 or 20" bar, if the bar is buried the shorter one will cut faster but leave more wood to be cut.  Steve

Steve,

Ah, okay, thanks!  I won't worry about it. :)

Just curious as to why you're selling the Husky?

instead of having different bar sizes for your dolmar

why not keep that sweet husky for larger logs, it can handle 20" or 22" bars lengths not a prob

the dolmar has slightly less grunt, so i would use that with a 16" or a 18" bar

The husky was a junk saw.  Cut nice but was broken all the time. 

1) Had to disassemble and clean oil pick-up when it stopped oiling the bar.
2) Had to replace the plastic rewind pulley twice.  I now use the compression release religiously to take strain off the cheap plastic pulley.
3) Had to install new set of pawls on the rewind on second pulley replacement.
4) Replaced 3 Broken chain brake handles even though I never once engaged it or dropped it and it only travels 20 feet.
5) Broken anti-vibration spring had to be replaced.
6) Muffler bolts fell out and had to buy a new heat shield and new bolts.  Assembled with blue loctite.
7) Muffler bolts fell out again.  Had to buy a whole new muffler kit.

The Dolmar will handle a 24" bar but I got it with a 20".

These days I only cut loggers cords of boiler wood that I have delivered.  I go through 20 - 30 cord a year.  I don't have the time to get out in the woods any more so I'm just buying the wood.  Still costs me half the price of heating with propane.  Last year I did build a new driveway into my place and got into some really large trees I had to fell.  But even with a 20" bar I can still cut them down okay so no real need for a larger bar.

Mainly I want a saw that is reliable.  I'd sell the husky and buy a Stihl or other brand for a second saw.  I may actually look around for a non-runner I can pick up cheap and rebuild or repair.  I did small engine repair years ago and I enjoy working on stuff so it might be a fun project.

LOL, i see
that prompt me to read reviews
generally huskys are a pretty good thing [i have two of them, not a prob]
the 562 appears to be a lemon

i cant see how the length of the bar would change the cut speed its how much of the bar is in the wood that slows you down except when the bar doesnt reach all the way through which was already said then the longer bar would have been faster by the time you cut down the back side  :)  i have a 20 24 and 28 inch bar for my 441 stilh and i cant tell any difference in the speed of the cut in the same size wood with any of them  but i do run the shortest bar i can for the size wood because im lazy :D  its a long way around a 28" bar with a hand file :o :D :D :D
