Please excuse my reply to the thread from the dead! But I feel this is important for lurkers looking like I did today.
I’d like to add some stuff for those of you who have searched high and freaking low for info. This was my first oil change on a diesel let alone a tractor for my father in law today.
Total nightmare finding actual info. Shop manual doesn’t even tell you oil weight. Virtually no one has filter P/N cross reference.
I did the work for you and I hope I saved your day.
Capacity & weight: 3.6qts 15w40 Rotella Non-Synthetic
Filter: OEM P/N: 72201898
Oreilys WIX Oil Filter P/N (Non-synthetic): 51394
Oreilys WIX XP Oil Filter P/N (Full- synthetic): 51394XP
Get ready to get nasty. Changing the oil on this tractor sucks.
Pan bolt on under inboard starboard side is 3” above frame rail so you can’t use a ratchet do get it completely off. You’re going to need a 3/4” wrench. I used a 3/8 ratchet with a 3/4” socket and a cheater bar to break it loose, the wrench to finish it off.
Filter is sideways on starboard side behind wiring and metal bracketing that’s virtually non removable for the purpose, oil fill plug on port side of block is behind wiring as well and you’ll need a nice long fill tube.
Get a drop cloth, some rags, and get ready! Oil spills all over side of block from filter (requires Type F socket cup or big adjustable plumbing wrench for removal) and on frame rail from the pan bolt. Oil will spill onto frame rail and run down the j channel to the area under where the seat is.
Also learned used year old diesel oil is nasty as ****.
