tell the dealer you want a "Service Manual" for a ??? and you want him to order one.
I got one for my 3040, it took a couple off weeks but I told him when I ordered it there was no hurry. A couple weeks latter I was going to give him a call and check up on it, I was driveing home from work and I noticed a bunch of greeen tractors in a lot north of town, stopped in to see what was going on. My Montana dealer was moveing to a bigger lot / building, he knew he had the manual but it was still packed up somewhere, one of the girls setting up the office dug through a couple boxes and found it for me.
It is definatly better then the operators manual that came with the tractor but but not as entertaining to read. I don't know if I would do a rebuild with it but if you change the oil, minor repairs etc its worth the $50.00 it cost.
