T Post Drivers

[BukitCase]

This is the one I bought a couple years ago

99E-M Post Driver 2 - 7/8" Max Diameter Recommended For Military Use and Drill Stem - Rohrer Manufacturing

ordered it with t-post sleeve and one that fits 2" square tube. Driving T-posts in less than dead of summer, sometimes it's hard not to overshoot. Rocks can deflect of course, and it takes a little longer in hard dry soil.

I use the 2" square sleeve on an adapter I made - welded a cap on 2" x 1/8" wall square tube, then welded a cap on an 8" long piece of 4" square tube and welded the 2" on top of the 4" - this lets me "pencil point" a PT 4x4, lock the "adapter" into the driver, slide the whole thing over the post and drive it in.

Dry weather with the 4x4's is slow, and I haven't tried NOT pointing the posts first. I have a bucket full of today's version of "penta-40" that I soak the cut ends of the post in first. So far, so good...

Even the larger version runs fine on one of the "hot dog" portable 120 volt compressors - mine's a Campbell-Housfield. It'll run on a 4 kw genny ok, which makes the whole thing "field portable"... Steve

Here's a gas powered one I just found. Might be nice not to worry about hoses...

With all of these drivers it is important to assess height of starting post, where the trigger mechanism is, and how tightly the guide holds the post. I should have mentioned that I'm in the middle of driving 8 ft vineyard posts to a final height of 6 ft in stony ground. I'm pounding about 1400 posts in what would be ~ 5 miles of trellis. Each day I can get ~80 posts in including unstringing/stringing each row. Wish I could go faster.
