Please add any tidbits, suggested or preventative maintenance items as well as what you've had to fix.
I have a 770 and it's been a great tractor but over the years, it's needed a few little things to keep it going properly.
Engine
Has been bulletproof and has required nothing but oil changes & filters
Hydraulics
Blew a hose or 2 on the FEL. No big deal. I think I now keep a spare on the shelf.
It's been leaking towards the front of the transaxle over the years but got pretty bad lately (like almost a pint per day). After a good cleaning of all the oily crud, I found and fixed the issue. In this diagram, part #7, those brass gaskets needed replaced. All 8 of them cost about $13. Remove the right fender and you'll see the large (22mm?) bolts. Pull them, replace the inner and outer gaskets, tighten them up TIGHT and reinstall the fender. Takes about an hour to do the whole thing.
Electrical
Turn key on, good dash lights but no start. EVERY TIME this happened to me, it was a bad battery cable. Happens about once every 10 years.
No headlights, no dash lights - Check the 5 amp fuse in the panel near your left knee. If the fuse is good and the taillights work, check for loose wire connection at that fuse box.
Body, Tires...
Yea, except for some minor dents/scratches, the body/frame is good. I use Fluid Film on the couple spots where paint is gone and is susceptible to rust.
Tires/rims - A few important things. If your rims look like they're going to need replacing, start shopping soon as they're hard to come by and pretty darn pricey. IIRC, it took me months to find replacement rims.
Another thing about front tires. The numbers are NOT the same in terms of diameter. E.g. on my tractor, I have 6.00x12 front tires. 6x12 tires are not the same diameter and can mess things up.
