Fastball,
If I might suggest an alternative. Let me guess that you don't have alot of tools or drain pans or ????
While posters are well intended, they may have forgotten long ago what it felt like to approach the idea of a lengthy list of tasks you've never done before.
So my alternative is this. Start with finding out from your dad what things have been serviced in that 800 hours and at what point were they done.
Then, start with the easiest to do and work forward over time until you hit your limit.
Why this way? Because let's say the engine oil hasn't been changed in 700 of those 800 hours. If that was the case, you can change it once yourself and then put some engine flush in and change it again. Why this? Because if the oil is that old in years and in hours, one change isn't going to get it good. And you doing both changes keeps cost down but learning up and your engine oil is really clean.
Then you could do the air cleaner also and did your dad grease the unit regularly? If not you could grease the unit to find out if you have any Zerks that are jammed up.
My point is, I'm assuming you are limited in your equipment and in experience, so do a few things well and then see what else you might be capable of doing and learn slowly. THEN, there will be things to have the dealer service person do preferably on site. If you have him do everything, its too many things to remember in too fast a time. If you get the easy ones out of the way first. . . . you can cross them off the list and off the billing slip so the service guy doesn't do them.
Now don't get me wrong, I'm not talking weeks of delay. I'm talking you maybe doing your items you want over a couple days after you've assembled the needed filters and oils that YOU WILL do.
The goal is not to stretch this out over weeks, but rather to reduce the list in length for the service guy to do that YOU CAN handle. For you to attempt to do everything on your 1st effort I believe is too daunting in size and lengthy in effort.
Let the service guy replace the belts and torque all the bolts etc.. Maybe if he does the hydro change, because once done you don't need to do it for 400 or 500 hours and hydro isn't as important as the engine oil getting thoroughly cleaned . . . Because the hydro fluid doesn't get contaminated like the engine oil does.
My point is, do some and have some done. That way you can use Tractorbynet as a source for suggestions on choice of engine oil or gearbox oil or grease or oil flyers etc. And let the service guy deal with the harder items and choices so you can SEE not just read and guess.
Again, I think it's important you get your hands dirty on a couple of things or a few things. And do them before the service guy comes so he can make sure you did them right before he starts doing other things.
With this idea, you're learning but not risking. . . . and you are also saving money.
One last thing. Find out from Tractorbynet posters what filters will work on your tractor for the items YOU WILL DO YOURSELF. You may find big savings on some compared to genuine dealer ones. Most of us are U. S. based so we don't know why products are available to you or at what prices.
Just my ideas for you to gravitate toward self reliance. But start with pumping your dad on anything he had done over the years (and when) . . . an important piece of your decision making starts with that.
just my thinking for some stress free learning.
P. S. Whatever you drain out, measure, so you know to put back at least that much. And save what you drain so you can show the service guy.. It does cost you for him to look at it but it could tell him alot (if you do my two times oil change I'm suggesting. . . . save each draining separately and preferably in clear plastic bottles (hint, he would look for shiny metal flaking in the oil).
