hydraylic hole diggers

[pinehilltexas]

Anyone have experience with the hole diggers that mount on the bucket of a loader tractor? I'm looking at one for a tractor that has a 14 gpm pump and want to make sure that it will deliver enough to drive the digger. The digger wants 12 to 20 gpm. There's also concern about running the lines from the valves on the rear of the tractor - they will be fairly long and I wonder if there will be much of a pressure drop. Anybody been this way before? Would appreciate feedback.

Hello Pinehilltexas,
I have a Danuser hydraulic digger that I use off the fel on my deere 3320. The motor for the one I want requires a small enough volume,I run it off of the remote outled at the loader arm with the factory installed valve, which I manually hold. Works fine for my 12" auger with teeth, but in this rocky soil I wish I had the hydraulic flow to go with the bigger motor - a medium rock will stop mine but it does 90% of the work so its not much of a PIA. As I understabd it, the bigger the motor displacement the more torque; and for a constant displacement more volume+ higher rpm but torque is independent of volume, only based on pressure.
I thought about rigging up a Prince PTO pump with thank, or rigging up somehing to my pwer beyond, but it was too much work. Bigger tracor with more Hydraulic capacity would be easier.
Good luck
Dave

Thanks ddaacc. What sort of volume does you pump produce?

Pinehill, the rated output for the 3x20 series is is 8.6 gpm at 2500 psi. The motor on the unit I bought is recommended for 5 to 10 gpm input. Pick a unit iwth a motor matching your supply and it will work fine. Sorry I cannot type too well at night!
