A question for Mr. Losey. A service manual seems to either not be available for this tractor or was never available. Would a 105 manual cover most everything? 

I had the same problem trying to get service manuals for my 4-175 and 4-210 as well.

All the aftermarket manuals cover 2-85's, 2-105's etc. but I haven't found any for the newer series like the 2-88 and the 2-110. Just curious as what to use as I'm in the process of buying a 2-88.
