Here's me running my 441 with a 16" bar and an 8 pin sprocket. Makes quick work of processing and less leaning over for each cut. These are ash logs, and I know I should have had my chaps on and my boots on.
Saw bucks are a very useful tool.. One that I would like to have The only problem with them, is cutting multiple logs/sticks. Always be aware of were the bar tip is and the other pieces of wood. Kick-back can happen when the bar tip hits another stick, while cutting a different stick/log. Nice saw BTW..
I agree on the kickback. What I like about them is when doing smaller stuff, you can load up 60-90 pounds of wood and it holds it in place better so you don't have the cutters stuck in the wood as often. It's also great for making noodles. Say you cut a large diameter log into 6 inch thick cookies. Then you lay the cookie in there and cut, then stack the 2 halves and cut again. Without a saw buck, it's harder to hold those in place.
Nice, mine is on it's last legs... or actually last inch of the cross members. I go big, biggest bar and biggest saw, pile the logs as high as can be, and use a ratchet strap if there are smaller guys on the top. Either way, it helps your back and keeps the saw out of the dirt. Still wonder if I should go with the traditional X style or H style for the next one. H holds more but X can fold flat.
If you're loading full, the H sounds like a great way to go. I like the X for the way I use it. And it folds flat.
