Extra Cub Hydraulic circuit

Men of wisdom, I am working on my angle blade project and things are going well, I was off a little on my estimate for this project by about half $$. Trying to do every thing right and my comfort margin is high, my question is this (only cause I don't know) what is the difference between Hydraulic quick coupler and a power washer QC? I only ask because of an extreme price difference. Realizing they both can handle 4500 psi and they are both liquid (oil and water). Again I have been known to be tight with my money but willing to pay the price if I have too.

Thanks Guys, Bruce.
 
the hydraulic quick coupler shuts off the flow of oil and the power washer quick coupler is still open and will allow flow
 
If you are using the touch control system as an hydraulic source, remember the pump does not have an internal pressure relief. The pump needs constant flow. If you were to dead head the pump with a disconnect, you would have a serious problem.
 
Plan on running from the TC to a control valve with pressure relief and open center. when not using the blade I will connect the hoses together to complete the circuit. From what I have read on here and other sites....it should work?
Getting a little excited on this project, I split the tractor yesterday to work on and inspect the clutch, while I have the HYD lines off thought I'd install the bypass block and fit every thing together. Been working on AC's for a few years and I am enjoying this little cub.
