It is time to invest in a decent post hole digger. My dilemma: to buy one for the 1025R or the 4052M (double the horse power). I guess I could one day use a gigantic auger, but I have aspirations to buy an excavator.

I mostly want to concrete 6x6s and 8x8s for small building projects. Battling rocks and roots is an issue.

I don’t have a ton of experience with a tractor post hole digger. My family got one for our 3 series but quickly realized it was near unusable due to the clay we had a lot of. It wasn’t a power issue, it was a weight/downforce issue to get it to hook up. We sold it shortly and got a Dingo skid steer to use for post hole digging because unlike a 3-point it has power down and since it’s hydraulic you can reverse the auger spin if you hit a root/rock. So that said I’d look for the heaviest 3-point hit post hole digger you can find. Or just modify one to add weights, I’ve seen a lot of those type of mods. As for HP the Dingo is ~25 HP and has never felt like we needed more for driving the auger so I think the 1025 would cut it power wise. Can the 1025 lift a long enough bit for what you want?

I wouldn't worry about the power much just the lifting height. I have the 1025R with a PHD and it will barely lift the auger high enough to clear the ground. And that's with the shortest augers you can get.

Don't some post hole diggers have an option to add a hydraulic cylinder for down force?

There is that and then there is the force required to get the thing out of the ground when it screws itself in because of the soil. There is no reverse on a tractor PTO to unscrew it. I have a friend with a 1025 and he returned the PHD to TSC after trying to drill foundations for a deck and he had to get a big farm tractor from a neighbor twice to pull it out of the ground.

You definitely have to pull the auger up frequently when digging to avoid getting it stuck. And carry a pipe wrench to unscrew it if it goes too deep. :laugh:

Been there, done that and that's why I got rid of my PTO powered post hole digger many moons ago. If I were to ever get one again, it would be hydraulically powered just to be able to reverse the damn thing if it gets stuck.

Went with a green PHD400 to get depth on the 4052M. Won’t be digging anything until the ground dries a bit more though.

The 2 finalists were this one and Everything Attachments’ 6900HD. The wait time, not the money, was the final decision maker.

Lift power, and tractor weight (on the front end) are very important.
PTO horsepower is important too.

I love my 1025R, but quite frankly, a post hole digger is not well suited for it.
Here are my results. Moving the 3 pt control even a 1/4" might make the auger flatten the rear tires, and dig in 6 inches, killing the tractor. since the tractor doesn't have enough lift capacity, it cannot react to pull the auger back up out of the suction.

Sounds like a wise decision to me! Maybe consider the down-force option as well while you are at it.

I would say/offer the same thing ↑↑↑
