Hydraulic Cylinder Controls

Mule Magoo

I'm building an attachment for a skid steer to work almost like a grader, the grader portion will need to hang off the side of the machine and pivot when it comes in contact with an obstacle. The cylinder will need to retract at the added pressure from the obstacle and extend when the obstacle has passed. I'm having difficulty figuring out the best way to accomplish this, torsion springs and compression springs didn't work. There was a similar setup on a mower (see pic). It looks to me, that there is a single acting cylinder, followed by a manifold, to an electric pressure switch (just a guess), to an accumulator. Any help would be greatly appreciated. There is also a video
22 seconds to 44 seconds in.

Are you looking to have the sort of relatively civilized and controlled retraction motion that the mower has? Or are you just looking to have something to allow motion so this attachment doesn't get snapped off if it hits something (like the springs on a snowplow)? I'd be hesitant to add hydraulics to the mix unless you need more precise control.
