Woods Groundbreaker 7500 Backhoe Inoperable

[mkenney]

Good Afternoon Everyone,
Long time listener, first time caller. I bought a Ford 1920 tractor yesterday at an auction that came with a Woods Groundbreaker 7500 subframe mounted backhoe that operates off the tractor hydraulics through the remote. This tractor had previously belonged to a cemetery in a nearby state (maybe I should call this tractor The Gravedigger!). When I went to pick up the tractor today, I noticed that the backhoe hydraulics don't operate. I was able to get one stabilizer leg to drop, and that's it. I have tried reversing the remote connections, tried operating at various engine speeds, pto engaged, pto disengaged, 3pt arms raised, lowered, etc. I am unable to find any manuals for this model (manufacture date stamped 1997 on the boom), and am not sure where else to look. At this point, I am thinking that the relief valves are gagged. Short of connecting the lines to another tractor, does anyone else have any ideas?

Thanks,
Matt

How many lines connect from the tractor to the back hoe?

I think some of those Fords had a selector valve to select either loader or back hoe - 3 point hitch operation. Not sure if the 1920 was that way or not. Hopefully some one more knowledgeable on Ford will chime in.

There are only two hoses, I haven't been able to find any other valves, etc. My neighbor and I verified that oil is getting to the valve, we changed the quick coupling connectors on the remote, and got a little bit of movement out of the hoe, only to discover that one of the hoses on the hoe is leaking. I think there might be some kind of bottleneck happening at the valve, and will dig into that tomorrow
