Stalpen Tree Jack

[Edmccabe]

Has anyone used, or been able to purchase one of the Tree Jacks in this web site?

I have sent then several inquiries about price and where one can be purchased with no response.

I wonder what the capacity is on that thing. I mean the tree they have it against in the pic looks like it could be easily pushed by hand.

In that video the "jack" isn't moving the tree ahead all that much, about the same as a set of doubled wedges.

I wouldn't waste my money on that thing though, IMO. Any "jack" that can sink into the ground is inviting disaster.

A jack needs a sturdy level spot to rest on because anytime you're jacking over a tree, you are getting into some heavy duty forces.

A very true and important fact !
I prefer wedges and a felling lever .

Looked pretty hairy to me as well.
