| We had that problem this year while drilling wheat. 2011 Steiger 400 pulling a 50' JD 1890 drill with a 1910 TBH cart.
Our dealer seemed very familiar with the problem, as did the JD dealer (we called JD dealer to see if it could be a drill problem).
Both the Deere dealer and the Case dealer immediately suspected the female coupler in the hydraulic remote. Apparently this is a problem with the way remotes are designed, not a Case vs JD problem because the JD mechanic said it happens on the JD tractors as well.
The way I understand it is when the coupler starts leaking the oil leaks internally on the valve block. The oil leaks from the front side of the coupler to the back side of the coupler. It will pressurize the back side of all the couplers on that bank of valves. So when one coupler goes bad, all the hoses on that bank will pop out.
The Case dealer told us that it is difficult or impossible to diagnose which coupler is causing the problem so it's best to just replace all of them on the offending bank.
We actually had them replace all of them on both banks while they were working on it. Has worked fine since then. | |

Hydraulic hoses keep coming unplugged
