Awright, I'll say it. I'm a forestry guy so I can take the hit for the team if I make a jackass of myself.

Loggers don't have time to climb ####. Cutting a jack face is quick and easy. Slap the rams in and be done with it. Topping for rigging is a whole different issue. Leave the jack in the crummy in case you need it, and slay them stems however is most productive. Climbing is fiddly and time-consuming and should be avoided whenever possible. We're not Steve Sillett, you know.
 
residential work sure , but that is not logging. like the hatte said you don't have time to screw around rigging up every big stick. besides trying not to ruin the tree in the process .
 
Wasn't talking about climbing. A throwball will set a rope up 70 - 80' up in a heartbeat. Seems quicker and cheaper than a 1k jack setup. That's my only point. If the tree is backleaning bad enough to need that jack setup, a rope setup seems cheaper and easier, is all I'm saying. Jeff
 
all right I'll bite...

Climbing is time consuming, takes about an hour sometimes 2 to climb and rig a tree, in that 1-2 hours I can have around 6 trees on the ground limbed and bucked ready to skid, If I where just falling for a processor crew then figure about 20 trees. With a jack I would only lose the 10-20 minutes to hike back to the crummy and another few minutes of jacking... move on the the next...

Its about production mostly.

Secondly rigging trees for falling generally involves some piece of equipment to pull it over or a complicated set of come-a-longs and hand winches or even more expensive and heavier portable winches... The thing ya gotta remember is that many times we can't just park the truck next to the damn thing tie on and give er Hel. Yarder logging involves lots of hand falling and hand carrying everything.

For me sure I skidder log, but to pull a 3-5' doug fir over with just a 12000 pound skidder is a little like having a tug of war against a tank, with enough leverage I can win... but your back to climbing and rigging and hoping you have enough cable not to squirsh the poor bastard driving the skidder if things go literally sideways.

The tree jacks are light portable easily operated and tough the bonus is they come with their own built in back pack you if your smarter than the average bunny hugger you only need to make one trip to the tree... unless spring boards are involved then plan on more...

the other alternative is to use a shovel/excavator to push it over, if you have one, which I don't, and you have to be able to get the machine right next to the tree which as mentioned above not always possible.

Hope that answers your question, unless your just trying to justify spending 1k to your war dept. in that case ignore everything...

the throw ball makes a valid point, almost.

In doug fir ceder and hemlock there are rarely any branches I would trust to hold the weight of the tree, if there are they are considerably more then 80' up. Unless you can tie a boomerang on to that throw line and get it around the trunk...:rolleyes2:

For oak or maple or many broad leaf trees then yes you have large stout branches to toss the throw ball over...

But you still have to pack 1-200 feet of bull line out into the sticks with all the associated rigging... then spool it up and pack it back... alone... while getting paid by the stick... (did I mention no groundies)

So what's that jack weigh? I could set you up with a system that weighs 30 lbs or less, that you can set up in 5 minutes or less, solo, that will all fit in a five gallon bucket. Base tie the line, rig the pullies, lock off with a prussik, pretension, and finish off, no groundies. Just seems a lot easier and cheaper than that whole jack setup.
