The reason for the small heads on the swing booms is so you cant over load them in a turn. It cant hold the hitch behind you.
Ohhhh its not going to cost much just lots and lots of time.....
I never under stood the bunching with a cable skidder to a grapple...
Dont get me wrong im a sucker for a headache myself.. Why are you using a swing boom just to get away from the cable skidder?

it saves alot of time when the ground is steep and the skids are long.
Bingo.
Accumulating a reasonable turn takes a lot of time. Dozers bunching for grapple skidders is really common too. We do it with jammers. Little machines accumulate a large turn for a big ol' grapple skidder. yes, it could be a forwarder instead. 2 or more cable machines might feed one grapple skidder, depending on skid distance.
I think the swing boom will not be regretted, even if you're not dealing with steep ground. Especially for what its going to cost you
When I said mechanical leverage, I was meaning when the boom was fully "retracted" with a big tree on...you go around a corner and the boom is so high up that it can tip the skidder where it never would have if it was a cable dragging it.
I guess I mean a much higher center of gravity. That's the biggest issue I see with one.
And I am glad to see a 540 owner say his machine takes 800-1000' at a time "reasonably". I know guys who try to take double that. And they do, but they break sh!t all the time too.
I have my eye on a 748 G-II D/A with winch, heat and AC both work, chains all around, and a new engine and tranny....$45K.. If it's still there in 3 months, I'll try for it. Need to pay off the F550 first.

I dont know about that, going around turns with trees on the road to help timber stay in the road with a grapple holding a tree just above the ground is ALOT different than going around it with the grapple let down, dragging the tree. They will turn over fast if you let too much side force go on the grapple, it has nothing to do with the log but everything to do with the position of the grapple arch and where its load is coming from. Same physics go for a cable skidder, just not as exaggerated. .

??? Your point is not what he was talking about??
Are you saying that the swing boom can't put the butt of the tree in the exact same position as any other carrying system??
Or are you just trying to explain something to others, that we already know???
I will explain again, regardless of the carrying system, cable, swing boom or single/dual grapple. There isn't any difference to the skidder and the center of gravity ONCE the butt of the log is up in the proper carrying position, up and back of the rear axle, BETWEEN the three systems.
Between all three systems if a log it is too high for a turn, it is too high, the skidder will flip regardless of what system is holding it in the wrong position. One great advantage I see in the swing boom is I can manipulate the center of gravity to the opposite side of the pull to put the skidder back down, no other system can do this.

Im saying that that boom grapple is alot more likely to tip your machine than you think. Hows that? There is a difference in my experiences.
