I also have a Case 446. When I bought it I went to a Case tractor dealer and had them order the shop manuals for me. The manuals ended up costing me more than the mower but have been well wort it. If you have a Case IH dealer around you I would check with them. Im not sure if your 446-75 is like my 446. If it is and you cant find the manual I might be able to copy and email the info that you need.
