Posthole Digger Anyone know the RPM of a Post Hole Digger?

OHHHHH Excatly what I want.

So explain to me the long bar on the Trencher? Trying to prevent stuff from flying out? I wouldn't be anywhere near that thing went it started up.

Love the stump grinder. That would taking out my giant maple stumps I have on my property.

It looks like it would take out the giant maples, period.

Are you planning to build a hydraulic PHD that attaches to your PT's implement arm?

I'm planning to either buy or build a hydraulic PHD for my Mahindra 5525 that attaches to the ML250 FEL bucket. The hydraulic flow on the 5525 is 10.5 gpm at 2100 rpm on the engine. How does this compare to the specs for your PT?

Like you I've been looking for a suitable hydraulic motor. No luck so far.[/QUOTE]

18 GPM at 3000 PSI. Still doing my calculations. I thought I could make this a multi use tool but that is not going to happen I think. That is unless I make a 3point adapter with a Hydraulic PTO and then buy used implements. Let me know how your project turns out.

Just working on an idea for my PT. A winter project. Wondering if anyone knows the RPM's A post hole digger attains. Trying to find a hydraulic motor that might fit a few different bills..

Carl, If I had mine hooked up, I could tell you. I have the PT hydraulic auger or planter head, and a 24 in auger for planting large shrubs/trees.
I think the auger tip speed should match the material you are trying to go through. Here in Florida, all sand, you can get down to 3 or 4 feet real quick, but using that auger in shale or rocky ground might require different speeds. What I am saying, is that there is no set speed. You look at the work in progress and vary the rpm accordingly.
