Grading BX2350 Hyd. Angle Rear Blade

[actionaj]

"Bret Mc" No I don't have any check valves or relief valve it is straight off the remote valve on the tractor. And as stated the cylinder is a little over sized and it can bend things if your not careful.

Bret & npalen; As for going over center it uses the momentum of the blade swinging to break it over the center point. When the cylinder is fully retracted quickly shift the valve in the other direction and the blade will keep going in that direction. At the fully retracted point I built in a little slop in the cyl. rod clevis. This allows about 1" of play on either side of the cylinders center line. So when the cylinder is retracting at speed the momentum of the blade will cause the cyl. to break over its center line. And by quickly extending the cyl. it will continue on in that direction. The external stroke limiter is how I fine tuned it. So that when the cyl. is fully retracted it is not pulling the crank arm tight.

I would like to post a video of it in action seeing it work is really cool. I have never posted a vid on here before but I will give it a try.

That makes sense to me now.
Good idea!
