limb zipper

[treebing]

this thing looks pretty damn clever. i wonder though if it only works next to the trunk because pruning at the tips you would just pull down the branch. anyone ever use one?

 

[Tom Dunlap]

That is a clever pruner. Seems much more ergonomic.

IT seems like it wouldn't work for tip work though When I watch the vid in frame/frame it looks like it would be possible to add a tab and small pulley to make it into a traditional type head.

Yeah does seem like it requires the rigidness of a branch collar or thicker branch. I don’t see this working for smaller cuts at branch ends like what Tom said.

suited well for growing knot free timber.

The home page has text that says it is not for small branch ends, like pruning fruit trees.
$395 + Tx
Only 1.25" branch diameter !

I sent an e-mail asking:
1. about purchase of an adaptor head to use w/ my existing poles.
2. just the LimbZipper head, w/o the rest of their "system".

After reading more thoroughly:
"To have a good LimbZipper pruning experience all components of the system need to be used together. This allows the worker to have everything they need when they need it. Which is why the LimbZipper pruning head is not sold separately from the other system components. The pruning head is part of the whole LimbZipper system."

That device adds a whole new frightening dimension to the issue of getting it caught in your zipper. Yikes.

Hmm, looks like a good tool for a managed pine forest, but less so for the variety seen by the average arborist.

Maxes out at 1" capacity, I think. Doesn't explicitly state, outside of the ad copy for the saw that swaps out with the pruner head.

If I'm going to be limited to 1" or so, lets add in an air compressor and pick up a generic pneumatic pruner off amazon. Gison model is running around $150 for the extendable pruner.

@SumoClimber - suggest you read previous posts

Interesting tool and might work well for some folks.

The drawback I see is that it looks like the blade is on the bottom so as the blade creates a kerf, the weight of the limb is working to close the kerf the more the cut progresses. Imo, opening the kerf with gravity or an outside force is key to cutting limbs with a pruner.

Maybe because it's rated to cut fairly small stuff, the kerf closing is not that big a deal.

The blades are on both sides.

With a typical pruner, the blade comes from below.

I love the mechanics of it, more so with all the shoulder pain I'm having.. I agree that there is a limited use in arboriculture... Now in a tree plantation where crown raising for clear lumber and lack of taper is desired this seems to fit that niche! I can see some big issues if it gets hung up on a non target limb, removal of it might require cutting the non target limb!

Anvil should be on the bottom, it looks ass backwards, no?

Unlike most pruners both the top and bottom blades are sharpened. Most of the cutting action comes from the top blade about 2/3. The bottom blade cuts as well. Its main purpose is to undercut the limb to prevent bark ripping, especially in the growing season. In the video you see the bottom blade moving and thus draws your eye leaving you with the impression that is where the important action is. In this case looks are deceiving.

You are correct, both blades are sharp and both cut. The top blade does most of the cutting. The cutting gets easier when in full leaf and especially if the leaves or needles are wet. The weight puts the fibers under tension making them easier to cut.

Welcome @MrLimbZipper

You've got a clever tool there. I wish you all good luck bringing it to market.

You might find a productive market with arborists if you can increase your cutting capacity.

 

[southsoundtree]

I never considered that extra water weight being a help.


I wish someone told me a long time ago that adding tension helps with secateurs/ hand pruners.

Depends how one orients it to the limb, usually there is a choice ime.
