Hand Powered Chain Saw  E-mail

Hand saws are inefficient and can be difficult to use in certain situations. The only alternative, unfortunately, is an overly-complex, two-stroke engine linked to a sharp chain that will set you back a couple hundred bucks, rarely be used, spew out clouds of burnt oil, and likely endanger your pets and children.

So why not mix the usefulness of the chain with the efficiency of muscle-power! Well, a small company called Green Mountain Products is selling just such a device. Unfortunately I can't figure out where to buy them...it looks like Green Mountain Products is only selling wholesale. This isn't going to be the fastest way to cut down a tree, and I would be a little bit afraid of cutting a falling limb from directly below, but there's almost certainly no better option for emissions-free tree trimming.

Another eco method of tree felling, is to keep a domesticated beaver. Of course they prefer to cut down the whole tree, as their legs are a bit short for climbing.
However throwing them up into the tree does work.....

You can also get it at Sears. At least I bought one just like this a few years ago there. Works great for limbs that are out of reach but under about 25'.

This is a good idea. However, I don't feel its very safe to stand under the limb you are cutting off, as the man in the top right picture is doing. Maybe this should be used after the limb is removed from the tree since that is when the majority of the cutting will be done.

brian: just don´t stand underneath, take two steps to the side and that´s it.

I would suggest a ladder above the target limb, that way your not in the danger zone.

I have been using this saw for two years and just ordered another. I have added rope to the saw and cut as high as 100' by using a casting rod with 90# test line and teardrop sinker and casing over limbs. I then fasten the saw rope to the line when removing sinker so as to pull saw rope over limbs.
