I just looked at the engine blocks and there was a SN break. If your engine block has no place to mount compressor then you'll have to mount it under the engine behind the frt axle same as some older 4020's. AR50297 CYLINDER BLOCK 1 - 303518 (NLA) (MARKED R43310 OR R45980) (SUB FOR AR43496) (ALSO ORDER AR43852, AR48289, R32617, R46158, AR52160) AR52061 CYLINDER BLOCK 1 303519 - (MARKED R47020 OR R47110) (SUB RE70108, SHORT BLOCK) (NLA) This post was edited by Tx Jim at 12:39:57 01/20/13.

But when I looked at my tractor, part of the engine block was in the way. I included a picture that shows what I mean. NO this isnt my exact tractor, but it was a picture I found on the internet that showed the casting that is in the way (I am not by my tractor right now) [Reply]  [No Email]

I am in another state right now on business. Was planning on going to a junk yard next Saturday out here and was wondering if I should add a a/c mount to the list, wondered what they looked like etc. I hope this picture helps.

You need a bracket for underneath. I don't think there's enough room to mount compressor over the engine similar to the JD utility tractors. [Reply]  [No Email]

Just open up the PC #856 go to parts index type in this number(AR48199) and it will take you to the page. There was also a bracket for over the engine part # AR44967. I beginning to think the underneath bracket I was thinking of was aftermarket mount for a Year-A-Round or Hiniker cab Normally I would download the parts photo but my new computer with Win 7 pro is giving me photo "Nightmares".
