Maybe a cord of the real big stuff?! I'm only asking because I never have cut wood that size.....
Ya, you can do it, it isn't hard. go back and forth from either side in the same cut. KEEP THE TWO CUTS IN THE SAME PLANE. Nice and reallll straight. Real straight. Both sides. Straight. You are making one big cut, not two cuts that kinda sorta are in the same area. One big nice straight even cut, just from two sides.
Take your time, let the saw do the work. Once down a ways, whambo a wedge in the top. Now you have to enter the bar under the wedge when you switch sides (if you do it more than once of course), danger will robinson! Potential kick back here. Take your time, ease into it.
The straighter your two cuts, the less you might need to use a wedge.
Ya, that saw will do it. I did a bunch of almost that size with my last year one saw plan husky 137 with a 16 inch bar. That's like only...what..about 1/2 the horsepower or sumthin lak dat, from your saw.
Did I mention make both cuts straight? That's what works, no binding up then, and let the saw cut, no need to lean on it, it'll get there, you ain't in a timberboi sports competition.
Do you have sharp chain, correct depth gauge raker height? Joe critical for cutting, especially when you are sorta "pushing the envelope" on a saw.
Are these logs laying on the ground? If so, they will want to pinch at the bottom of the cut, hence the wedge will help again, and/or, sledge hammer a small piece of wood, like a cut off branch chunk, whatever ya got handy, directly under where you cut will be. A "timberjack" is also a handy tool to have, works great on medium beefy logs like that, it picks them up off the ground nicely. In fact, 24" is an ideal size to use one with, say like on ten foot or so logs.
Guys do this everyday, it is doable. After you do a few it'll seem normal. Just remember those kinds of cuts your saw is doing the maximum work it can do at all, it needs all the help it can get, which is you the operator not pushing it too hard, making sure it is getting the oil down the bar good, that it doesn't overheat, all of that.
A really good sharp chain takes a tremendous load off a saw compared to pushing a dull chain. Dull chains kills saws just as fast as six month old ethanol gas left in a can in the sunshine with the top off.
