Weekend update.
Did get new mountings for ripper done, old ones was D8N design making upper cylinder collide with tank.
Here´s one old and one new. The new ones got also a 3´rd arm to make it possible to have the drawbar for scraper mounted all time.
Here´s what it should look like with the drawbar. With hitch is removed, the drawbar *** will be locked to ripper. The original has same (see pic in post 21, page 2) and use only hydraulic valves to shut of lifting cylinders. I don´t know if that will work for me or if I have to make some sort of holder for ripper ***.
Made a trip today to take photos (another 120) and messurment of interior of the real one. Think I have all that needed to make this now.
