Power Beyond and Loader Simultaneous Operation

Do I get a finders fee for all my work.

Well I don't know about fees but you sure have my appreciation. Surplus center looks to be a great source for stuff, I need to do a more diligent search there on my own I guess and save you the time. Couldn't find much using google.

Is that picture of the same motor you showed set up for an auger? Is there a planetary gear in there? I didn't think that motor had enough torque (1500-2000 ft lbs)to turn the auger without being run through some type of gear reduction. Maybe it doesn't take that nuch torque.

This looks similar to what I am wanting to build. Any more info on the set-up you have pictured? Please!!!!!

Here is the thread about the hyd auger built by Woodlandfarms.

The hyd auger in the pic is direct drive.

This is my hyd auger built by Power-trac.

This is a hyd FEL mounted auger.http://www.tractorbynet.com/forums/...2548-hydraulic-post-hole-digger-new-image.jpg

Thanks, I didn't see any info about how it worked for him. Woodlandfarms said in his post that the motor had 10K FTLbs. That was not correct it has 10K in lbs. So I am wonering if his auger was about 12 times weaker than he thought.

I like the three detent valve for the spool though.

I will test my relief pressure (since I now have a gauge), pick my motor, valve, gearbox, auger,weld it all up and bore some holes, or break some stuff and let you know what I come up with. Maybe that will offset some of your finders fees

If I am understanding this correctly;
As long as I don't put full pressure on the loader the PB/auger would still turn although slower/less pressure depending on loader pressure. It would basically be a balancing act to get rotation and down pressure by me controlling the feed rate for the drill. When I stop applying down force I would get full auger force.
If that is the case then I think this would work because I could but pressure on intermittently with the loader which would hold with the weight of the tractor on the bit until it reached depth.

You are correct.

I had considered using a motor spool but decided that I would want to use the same spool for the grapple.

A motor spool, is mainly needed (for example) with a bushhog where it has a lot of mass that has to spin down when you shut it off. Shouldn't be really needed with an auger.

I saw that 10k ft lbs error also. It should be about 833 ft lbs, which is still plenty.

You would have to go with a very large motor to get much more ft lbs, and the speed would be slower,

I sent him a PM asking if he had stalled the auger very often.

My auger will stall if I try and drive it down real hard.

Here in Florida, we have a lot of sand.

Your auger picture has a large bit. Understandable it it stalls. Looks like it could also have planetary between the motor and auger.

I will be drilling in rocks and roots. I would like to find out how much torque it takes to shear a 3/8 shear bolt in a two inch dia shaft and use that as my lower limit.

The hyd motor is direct drive.

Why do you even need shear bolts?

You will just have to try different bolts.

The relief valve should protect the motor.

That is a planter auger.

I still plan to use the gear box, because I think I need around 1500 ft lbs of torque. Most auger gear boxes have a shear bolt on the auger to protect the gear box.

The motor will be protected by the relief valve like you said.

I want to use all of the potential of the gear box. So if I use the shear strength of the shear bolt as a minimum I will be able to match the motor torque with high enough torque to shear the bolt. That is what a lot of people says happens with PTO system. Now if that is my MINIMUM. I coul increase the bolt grade, take a chance on stripping my gear box, rely on the relief to protect my motor, and possible be able to drill through tough roots/rocks.

So far, I came up with 1350 ft lbs to shear the bolt based on .375" grade 5 bolt. This exceeds the wheel motor by about 500 ft lbs. I am not sure of my calculations, but that seems to fall in line with others I have seen online.

Here is just an example of a hyd planetary gear setup, showing a chart to the right.

Model EP10 | Danuser

They are using a 3.66:1 gear ratio to get it down to 48 rpm, and the chart shows the resultant torque with different psi figures.

Just got to get high displacement motors at a good price. Keep an eye out on EBAY.

Here is a mount for the side of your bucket.
