Plumbing extra remote for auger on Massey Backhoe
I also posted in the custom equipment subforum but they led me this way for additional help. I own a 2015 Massey Ferguson GC1710 with a backhoe. I recently acquired a small hydraulic driven post auger that I would like to mount to the backhoe boom. The brackets and mounting the unit and whatnot are the easy part for me but I am trying to figure out the best way to actually spin the auger.
My initial thought was to basically treat it like one of those rental towable units from home depot(with the head mounted onto the backhoe instead of my hands!) and have a separate power pack - a gas engine like a GX390 or similar to run a hydraulic pump with relief valve, tank, cooler, lines, spool valve to auger head etc and have the hydraulics completely self contained and separate from the tractor. A portable power pack basically.
The more I think about it, the more I consider running it off the tractor hydraulics though. Which is what I am hoping some of your experiences will help.
My only concerns are I do not want to lose any of the loader or backhoe functions to run the auger. I am also worried that the tractor might be on the low side for hydraulic flow and pressure. The auger unit claims 2600 psi max, with gpm from 3.7 to 14.7 max. Those home depot towable style do roughly 1900 psi and 5.5 GPM. From what I understand the tractor will do around 2000 psi but only 6.6 GPM - and its likely the steering takes 2 GPM or so to run.
Am I asking too much from the little tractor? I mostly use a 6" or 10" auger for fence post installs but dream of also using it for small screw piles for decks and sunrooms. Even if I had to do the last couple feet with a cheater bar occasionally lol. I have used a 3pt hitch style auger with the tractor before and it has no problem sinking the auger bit in like a screw pile until the head is sunk - if you're not careful with the controls.
I am also currently in talks with a gentleman that makes a remote valve kit with additional working lines for this exact machine but I would like to confirm the tractor itself will actually run the auger reasonably effectively and do what I want it to do before I go that route.
Anybody else have any thoughts or ideas?
Sorry about the essay but thanks for reading and your input.
