thanks max
From what i have managed to ferret out most people had the mower base and not the tiller. i did find pristine paint under neath the hand grips on the handle. i taped them off to keep as a reference as i may paint it correctly in the future. l did find on here a member posted a pdf of a parts manual. i was able to scale of the picture for dimensions of the ripper which was missing. i would like your opinion if you can. if you find the parts manual on here take a look at the exploded diagram part 18. im trying to figure out how the spring steel works because the ripper tyne would move backwards if it hit a root and the spring would have to be fixed therefore cannot it being of any use apart from stopping a little lateral movement i will post some pics later in the week when i finish the engine repairs minus the ripper. that will take me a couple of weeks to fabricate.
once again thank you for your reply as any information is invaluable
