Anyone ever built a post hole auger?

[Jrus]

Has anyone made there own post hole auger for 3 point? Thinking about using a truck axle to build one. Anyone got pictures or advice?

I've heard of it. And I've contemplated it. Then I just rented one and moved on. If you do it, take pics and let us know about the build.

Long ago in my area, most of the farmers who had one had a homebuilt. Most of the factory ones were owned by contractors.

What did the farmers use to build there's with

Most I saw were Ford Model T and A rear ends.

For example:


If I were going to build one now, with junkyard parts, I would start with a differential from an independent suspension car. No axle shaft and housing shortening to do.

Ah, the good old days. Can you imagine Lincoln or Miller printing project drawings for something like that now? Lawsuits cometh, and that right soon.

you can buy a gear box for post hole augers and save a lot of head ache.
PRICE: $165.95
44 HP OMNI GEAR PHD 26 POST HOLE DIGGER GEARBOX


$129.95

Post Hole Digger Gearbox-2.92:1 ratio | Agri Supply #60680

when I rebuilt mine, I added a frame so it would dig straight holes, similar to the picture,

The ones from Surplus seem to be a good choice to go with.

I build one from an old BMW differential, put about $75 on the table for it. Frame was made from leftover materials laying around, drill is not exactly really good ($45 for a hand augur, garden use) but was good enough for testing it here on some sandy soil. Still have to make a good drill.

In this post some pics.

Good luck.

Don't forget to add a shear bolt or slip clutch!
A truck rear axle can probably handle a lot more torque that the PTO gears in your tractor's tranny can.
Good luck and show us some pictures if this thing comes together.
