Good morning all. I purchased an Agritec AT40-180 6' rotary tiller from a farm auction and have been searching the internet for an owners manual and a parts breakdown so I can order some parts to fix it up. I have not been able to find any thing on the AT40. All I am finding is AT20 and AT30. Any suggestions or can anybody point me in the right direction? I figure most of the parts i need to replace, like the tines and bearings, I can get pretty easily but I also need transmission shaft housing. I'm sure that is not going to be a universal part. Any help would be greatly appreciated.
