Any advice would be helpfull, thanks

Hi Chris,
When I built the gear driven scarifier mechanism for my box blade that you saw, I started out thinking exactly like you. The problem I had was working with the boxblade I already owned. It had the scarifiers already going through the main front beam but they were separated by the lift pin connections on each side of the 3pt bracket. The bracket also got in the way. I don't know what kind you have and you may not have the same problem?
In order to get the "flat bar" as you describe to all the scarifiers I had to section it up into 3 pieces and propel each piece ... using the gears and shaft. I realized that each "set" of scarifiers needed a frame of some sort so they would move up and down all together. If you attached your flat bar across the tops of all the scarifiers you would still need a frame for them so they can move up and down and stay located above the holes or slots they are in now. I was also afraid of "binding" when retracting or pushing down on the long bar, in case it flexed. Then you would have that "Chinese Finger" affect.
ovrszd posted a picture of his boxblade that already has a handle to pivot the teeth down or up. That's how most of the hydraulic ones are made. His would be very easy to modify by attaching a bracket from the pivot to a hydraulic cylinder. He is lucky in that respect. I thought about doing that but there was not enough room behind the front bar and the back blade to allow my scarifiers to pivot. My box was not deep enough. So I did what you are thinking about, except used the gear mechanism.
