If anyone recognizes the brand please speak up, I have no Idea.

Found this on craigslist for $150. It is weathered and has had some low quality welding repairs through the years. Here are a few pics after pressure washing the rust and flaky paint off. Note the leaky input seal and the bent tabs on the A frame where it attaches to the boom.

Here is the A frame after the repair. I used D.O.M. tubing 1/2" I.D x 1" O.D. for the middle of the mount. The side plates are 3/8" x 2" Flat Bar. Should be plenty stiff now.

The tractor end of the boom pole it tweaked a bit. The hole was also wallowed out by about an 1/8". I will attach several pictures that will show the arm in my mill after I leveled and squared it by the boom and gearbox mount. I figured it would be much easier to bore the hole larger with the correct alignment than to heat and re-bend the mount itself. Hope that makes since. Pics worth a 1000 words.Here ya go.

This is part way through making the bushing to weld into the tractor end of the boom pole. It is also D.O.M. tubing and ended up being 1" O.D. x 3/4" I.D.

I am 99% sure it was made by Independent Manufacturing Company (IMCO) in Neodesha Ks. Ken Sweet

IMCO, Thanks Ken!! I know the gear box is OMNI. Seems they are still made.

I owned 1 just like it back in the late seventies. We were a dealer for them until they went out. Real good machines for the $ spent. Ken Sweet

I refurbished an old Speeco PHD just recently and the gearbox was real similar. It had a leaky seal on the input also but was very easy to replace the seal. I did have a thread problem on a couple of the bolt holes that mount the shaft cap. The hexbolts were not the best so replaced them with slightly longer bolts and worked fine. Always a good feeling to "resurrect" and old piece of equipment especially when it will perform as well or better than a new one today.

Here are the boom and A frame after some paint. On the boom, tractor end, notice the bushing pressed and tack welded into place. Ill be picking up new pins for the A frame too.

Here is the gear box with the leveling arm. The allen set screw has been stripped out. Guess its time to drill and re-tap the hole for a 5/6"-18 set screw. Even the arm was rusted in tight, a little heat did the trick.

The output shaft had a pretty good bend in it. Ya know a little bend in the back would wobble like crazy at the end of the auger. With all the new tighter bushing areas I didnt want it to shake my little tractor when digging.

I was thinking Bridgeport mill and possibly a South Bend Lathe with a taper attachment. Oh you wanted the post hole auger identified!:laughing:

I'm envious of that shop equipment myself. Nice job with the hole digger!

When I look at your push punch, I want to reach for a pair of safety goggles....Fast. I have seen pieces like that fly out under pressure and go through a metal shop wall. Be careful. Ken Sweet

Forget the safety glasses I was behind a 1/2 piece of plywood when I was actually doing the bending. The Pin you see in the picture is a spider gear pin out of a suzuki samurai diff.

I thought that pin looked hardened. Thanks for being safe. Ken Sweet
