Timber retaining wall tie-backs...what to use?
(OP)
I am building a 6x6 timber retaining wall that will be about 5 feet high and 20 feet long. I need to figure out a way to tie the retaining wall back into the slope. Typically, I would use deadmen to do this, however I have two trees that about 4 feet behind the proposed retaining wall so I cannot excavate this area to place deadmen. Does anybody have any other ideas to tie the retaining wall back into the earth? I thought I could use some type of screw anchor but am having a hard time locating them for purchase. The ones I have been able to find are huge and are not used for a small application like my retaining wall. I thought I could use about a 4 foot screw with a 4" to 6" thread but haven't been able to find them. Any other ideas?

If I were to do this, here is what I envision:
8 foot 6x6 vertical at the corner, then another one every 4 feet. There would be 3 foot of bury on the 8 footers and 4 foot horizontals between the verticals. Think that would hold with approximatley 4.5 feet of earth retainage?
