I have an annoying leak of about 6 drops a day coming from what looks like the seal to the rear section of my SH. Looks more like motor oil but I don't believe it is. There's a small metal access cover about 6" X 10" across the bottom covering this area. Can this seal be changed without splitting the tractor like I've seen mentioned on here before? How difficult? Doesn't look too bad but haven't done one before. Also, what manuals might be best for me to buy for this tractor? O&M, T&I Shop, Service? Or all of the above? Thanks All!

There are Four possible leakers in that location. There is not supposed to be oil in the chamber, so removing the plate is not a deluge. But be careful anyway.
All but one can be fixed W/O splitting.
counter shaft to hydraulic pump drive shaft coupling at trans case. Remove cover, remove drive shaft (easy) remove drive fitting from trans, (need a 1/2inch tough bar to turn it out Lefty Loosy with trans in high gear brakes locked) then easy replacement.
Trans input shaft (directly above the first one) remove Pressure plate and undo coupling (after taking pictures of it!!!) remove center bolt in yoke. Remove yolk then seal is easy.
Liftall pump seal. Remove Liftall pump and replace seal, (see archives for many posts on how to do it).
4th is rear main. tractor must be split to do it.

Adding to Jim's reply: Most likely it is the transmission countershaft seal. You can quickly determine by removing the dust plate then peering up inside the belly of the beast.
It's not difficult to replace the seal without splitting the tractor. It does however require dropping the belly pump which is a bit awkward and heavy (not an issue if you have a Stage II Super H since there's no belly pump)
Tip: If you find a leaking tranny front seal replace both the countershaft (lower) and the upper (input shaft) seals together. If one seal is leaking the other is soon to fail!
