Anyone know the torque output of the auger drives?

[Marks481]

I am away on travel right now, but it is the standard PT auger, which I think is 2 9/16" (2" seems way too small, and it definitely is not a hex drive). I will take a look when I get back on Friday.

I purchased the auger and 6" bit from PT. Later bought a 12" from Tractor supply. I'm in TN with very hard clay (when dry) with rocks ranging up to 4" on most parts of my property. Sometimes find larger flat rocks which the auger will break or break loose if not too thick.
.
The 6 and 12" will bore with no problem during the driest (sp?) conditions. I usually run at 1/2 throttle. You can feel it hitting rocks, and bringing them up to the top. Not sure how shale compares but I found letting the auger "do it's thing" while applying "just enough" down pressure will usually get the job done. The trick is take your time and let the auger do the work. It sure beats hammering and post hole diggers. We have mainly used the 12" to dig holes for 1 gal plants.
Hope this helps. BTW, the TSC bits fit perfectly into the auger reciever--at 1/2 to 1/3 the price of PT.

Have no idea what the torque output is but as I explained to my wife, always stand clear of the auger--if it grabs you, it won't let go and it'll wrap you up on the bit. At 1/2 throttle, the motor barley changes pitch as it bores--taking about 1 minute for a 6" hole 2-3 ft deep.

Thanks for the info. Your note along with the other responses were very helpful. I am leaning towards the PT Tree auger (has more torque). However, I still want to know if there is a significant difference in torque compared to a Danuser MS-615 mini skid steer unit. Can you please read the label on the motor and post the make and part number? Thanks

I just have to say again that building mine, all in, was half the price of PT. Very very easy build.

As far as torque goes, there are some assumptions one can make.

With 8 GPM's and with an average speed of 154 rpm, then the displacement would be 12 cu in. With 12 cu in and 3000 psi, the torque would be about 5,732 in lbs.

So if you wanted more torque, and less rpm, you could go with a larger displacement hyd motor, say 20 cu in, and with 8 GPM's and a 20 cu in motor, and 3000 psi, you would have a motor rpm of 92, and 9,554 in lbs for torque.

Carl,

Did you figure or measure the rpm of your motor.

Carl,

No.... I have no clue hoe. It does not seem very fast. I doubt much more than 120 rpm at full throttle.

It has only a Power-Trac label and s/n on it.

Thanks very much for looking.
