Here's a tip you may already know about connecting hydraulic quick disconnect lines. I find that when the attachment has gotten warm from sitting in the sun or from being used--or if you accidentally operated the aux. controls with nothing attached, it tends to develop pressure in the lines. This can make it nearly impossible to connect hydraulic lines. What I do is shut off the machine, and then open/close or cycle the aux. control pedal/lever back and forth. This relieves any pressure making it easy to connect. Bobcat brand has a bleed-off valve built into the aux. connects---I wish I could find a cheap one to replace mine.

Yes that works well.
I have had it when the attachment was the problem. I do what you mention above before diconecting. However at times I have had to break the seal on the attachment hoses with a couple wrenches to relieve the pressure. Still easier then a big fight with them.

Gehl and the manual for my 435 recommends that after you shut engine off, to turn the switch back on before cycling the aux controls. scott

I believe the reason you need to turn the key back on is to open the solenoid.With the key off the safety lockout would prevent release of pressure. Mike
