Hi Joe, here´s how I sloved it. The ripper brackets back on machine was made new with a 3rd leg on low position.
then there´s 3 other parts, the coupler and 2 different connectors
Then there was a scraper coupler holder made to fit inside the cut out of ripper baseplate.
With the different connectors between base plate and coupler holder I can change so when not using scraper, the coupler is folded and secured in parking position, not interfiering when using ripper. Since it has same turning point as baseplate it´s just dead weight.
But when using scraper, baseplate is lowered and secured with the other connector, bolted with 2 screws (not shown here), one to hold coupler in holder and the other to keep coupler holder in right position. Now the ripper cylinder has to be disconnected (I use same valve function for ripper and scraper with the small hydraulic quick couplings), I hope that cylinder will be tight enough to hold ripper in high position (I will do a double set of o-rings in piston on ripper raise cylinders).
Here´s another view from bellow when coupler is installed in holder.
The basic design is copied from friends real D8 but adapted to work on my model. The only concern, as mentioned, is if the ripper lifting cylinder will keep the ripper assembly up when working with scraper but time will tell!
