I've seen a regular hydraulic jack inserted into the backcut to assist falling before. This was in the woods though not in a residential setting. I've thought about using a bumper jack / handy man jack with a L shapped brace and chain for pushing trees. It seems that a rope seems to help direct them better and has a ton more leverage due to the the height that you put them in at. Just look at the amount of leverage that you gain by having the pull rope at 20' rather than 6'. I should post pics of the 24" yard maple that I pulled over this summer. The tree was a double and both halves were about 24". I lightened up the outside one and topped it at 20 - 25' then fell the rest of the outside tree. Inside tree I roped at 30 -35' attached the rope to a big telehandler I had rented. Cut my notch, and pulled/wedged the second tree over. I dont thing that the little jack pictured in the pic would have had enough guts to pull that tree over. I think that the jack works about as well as a buddy pushing on the backside. I beleive that for constant use it might need to be beefed up. I'll see if I can find some maple pics...
opcorn:
in this picture i see,,,wouldnt a wedge and a smaller hinge work better and more efficient?
Am I the only person who sees this as a very unreliable push method?
...I think that the jack works about as well as a buddy pushing on the backside...
maybe if it woudn't have been so windy day. (and if I didn't have tree jack)
Any method of felling trees can be unreliable if you don't know what you're doing
Well, I can't afford to hire Superman... (and his obviously already working for you)
ok,,,so i guess you are saying this little jack is better than using a rope and a wedge,,,hmmmm,,,interesting,,,and dont forget about a better hinge,,,that helps the felling process easier and safer
I do not mean anything personal towards you or the "jack". I can see that it will push, I did not realize that it could push 2.6 tons. Will the foot print support that much, will the wood fiber hold 2.6 tons at that angle? What are the chances of it kicking out?
