The Case garden tractor Yahoo group: http://groups.yahoo.com/group/casegardentractors/ is a great resource. At the shop we have been combining two Case 446 garden tractors into one working tractor and repowering it. If you would like to check out the repower on the Case 446: http://www.jimsrepairjimstractors.com/case-repower-ingersoll.htm I told the owner I would find him an operators manual for the roto-tiller that came with them. I searched for quite a while and then asked on the Case Garden Tractor Forum. Within an hour at least two replies led me to where I could buy one.
