Testing of the Koller wedge.

Great video Muz but it looks very dangerous to cut dead trees like the one you show in the video?

These trees are predictably dangerous, provided that you take your time and think about what you are doing. These trees are less dangerous to fell than chalara infected Ash

Hi weasel squeezer, I had wondered about these and although I like the value of not banging a dead tree around I would rather use a Tirfor type winch with a kinetic recovery strap/rope. take up the tension gently and the kinetic rope would give the pull without shock. Rig up on one stump and only low down on the stem to fell so on the strongest part. The amount of jobs you would do like this is fairly small so the cost of a Koller is a fair bit since most of us have a Tirfor so only the cost of a kinetic rope , couple of hundred for a really good one, is much more recoverable. That said safety before cost so my comments in this case may be well off !!

Hello Dave, tifors are good, but there is alot of lugging around and setting up, which is not good on a site with challenging terrain. The Koller wedge fits in my wedge pouch, and takes about 2 seconds to set up.
P.S are you Dave of ‘inthewoods’ fame? - August 24, 2019 at 9:41 pm #5276
Hi Muz , outinthewood yes that’s me although no fame !! I get what you are saying about the set up but like every thing that’s just an alternate way and I think the Koller has a good place and it’s not that expensive.
