Auger attachment for backhoe on M59 Kubota

[TWD]

Looking to get an auger for my Kubota m59 to mount on the backhoe... they seem to be rated in torque. What's the max torque I can put on the backhoe of the M59 before I pretzel the backhoe or twist the whole backhoe :laughing: :laughing:

The price difference between 2900LB and 6000LB is <$1000 and the flow requirements are the same.

They have smaller ones too, I believe another member here on the forum has one of the smaller ones.

I live in the Sierra Nevada mountains so I planned to buy their "rock auger" auger bit to make sure I don't have issues going through rocks, etc... we have about 2000 feet of fence to put up perimeter, and then the inside pastures to do. This alone is around $900 for the 9" version as I plan to use 6-8" posts. At this time I don't have any plans for any different diameter holes.

You will not damage the back hoe if the relief valve circuit is properly set and the back hoes foot pads are fully lowered to reduce the forces created by the auger pulling downward.

I will give you the same advice that "he listened to" when he bought his post hole drill and auger to install fencing;

Purchase a small Vermeer tree transplanting auger.

The reason why is:

The tree transplanting auger having a tapered design reduces the stress on the auger and reduces the torque needed as all the dirt is being pulled up and away from the hole created by the auger base as it is digging downward.

Do not let the Vermeer dealer or anyone else tell you not to buy a tree planting auger it works and it will always work
for you and you can dig down as far as you need to set the posts. you will need to back fill a little more but the time
and labor you save will be worth the purchase of the smaller HTLS6K auger drive and the smaller tree auger.

The hole will be be a bit bigger around the top at ground level but a steel rake and flat shovel will be all you need to push the dirt back.

You need to drill the post holes slowly by lowering the upper boom and the auger a little at a time and just let the auger work without forcing it downward it will spit the dirt and small rocks out with ease.

After that you can drop all the posts in the holes and then set your top first if your using single wire to line up the posts


The smallest tree transplanting auger is something that you will not waste any money on as the design allows easy digging every time as the side of the hole will not be there to affect the augers performance when pulling dirt up ans away from the hole, AND you will be able to empty the hole easier if you have rocks and dirt clumps roll back into the hole with a simple garden hoe.

The tree transplanting auger will also remain vertical as it acts just like a plumb bob too.

They make tree transplanting augers that can grind through granite?

You can buy transplanting augers with conical cutting bits that cut into rock or compacted heavy soil.

If you have granite rock close to the surface you may end up buying an 8 inch auger with a full conical bit ring from bottom to top with a full row of conical bits on each flight of the auger from the base to the top of the last flight.

If you have that much black granite close to the surface it may be better to just rent a back hoe with a rock hammer and scoop out the rock bits with a good hand held post hole digger or use a big shop vac and a pair of Oneida Air Dust Deputies to vacuum out the holes.

I would talk to the local Vermeer equipment dealer before you spend any money on this as he may have a rental unit you can have for a short term lease and use for this.

You need really good rock equipment for surface drilling like this if your granite is close to the surface.

The nearest dealer on their site is in another state It's 1-2hr for me to go to anyplace useful, I'll be ordering online, and researching online.

Right now the Beltec+9" looking like around $2400-$3000 delivered depending on exact model/setup.

I was quoted $150/hr for the "equipment" on top of labor fees of $20/hr for 3 persons to do my fence work... it doesn't take much of that to pay for the proper equipment, even only doing 1-2 acre around my house, let alone any additional work

I think some are missing what your concern is. Not the down or up force of the auger but rather the twist. A backhoe really isn’t designed for forces in that direction but I don’t think it will hurt it. I used to own a M59 and they are pretty stout. I also own a small beltec I believe it is the NC-150. I have drilled 18” diameter holes up to 8’ deep with it using my skid steer. I bought the quick attach plates and was going to rig up a mount to use the auger on my mini excavator but decided not too. I have yet to need a hole somewhere I couldn’t get to with the skid steer. Out of curiosity why are you wanting to mount it there and not use a SSQA model?

Yes, exactly. There's absolutely no way the M59 backhoe can handle the model that has 10,000lbs of twist force, but hydraulically I could power it, my pins, mount points, and entire tractor would pivot if that thing caught a rock though... thus the concern is 2000lb good, 2900lb, 6000lb what is the realistic amount of twist pressure this thing can handle?

Another member here has one of the 2000lb rated Beltecs with an auger rock-bit and has claimed to go through rocks, I just posted on that thread last night after I found it asking him for updates but he hasn't been around in a long time. Here's his: http://www.tractorbynet.com/forums/kubota-buying-pricing/232773-new-m59-owner-5.html#post5091740

Why backhoe?
I wanted to mount it to the backhoe for ease of getting the hole in the exact spot I wanted without having to worry about clearing some more around it. Obviously I'll have to make sure there's room for my fence install, but some of the fences back up to forest/trees/brush that would make it very hard to position the tractor FEL with driving and not being off-camber, in a bush/tree, etc... basically for ease of use = backhoe.

Appreciate the input @BDOG

I also checked local yards (~1hr drive 1 way) and the weekly rental for an auger is $700. Makes sense to buy an $1800-2200$ model that's for sure.

Old thread, but I'd be interested to know if you found an auger that will actually drill through rock. I've put a mile of fence into rock on my farm but it has taken many hours on a full size hoe with a hydraulic breaker. I'd much rather drill holes if there was a reliable way. A couple of guys here have bought rock bits for the skid loader augers, but they haven't been much count.

The government conservation folks here tell me the correct way to build fence is by drilling when you have rock because the hammer is too slow, but I have yet to find how that's done. They of course told me that's how it's done but had no examples.
