Looks like day 3 is a bust while I try to figure out if I need to do something about the excess oil. Saw quite a bit of difference of opinion on the many older threads about this issue.
Yep, this is what I meant by going around the tractor... although to find excess oil/fluid is (IMHO) unusual, especially as you've already been running/using the rig and the oil has had time to circulate into all of those internal nooks & crannies. Draining a bit off, then checking the level (cold
and ensure that the tractor is
on a level surface) won't be that much of a bother..
As to non-grease-gun lubrication... WD40 is fine or 'Fluid film'. I use an Aussie lanolin based spray lubricant. I spray stuff like the 3PH arms, the parking brake elements, the mechanical parts of my 3PH quick-hitch, the collars of the female hydraulic couplers and, especially, the splines of the PTO... for ease of sliding on/off an implement shaft and as a rust inhibitor. Spray lubricating isn't an everyday procedure; I do it once or twice a year when I remember to do it.
Torque wrenching only pertains to what your manual stipulates/suggests for your wheels and, perhaps, your FEL. Other than that, you can simply go around the tractor (and implements, for that matter) with a set of ratchet heads or dedicated spanners (17mm is typical) and just ensure that any bolt/nut is snug/tight. You don't have to 'crank' on them, just see if they move and, if so, tighten that one up.
Make a note in your manual as to the nut/bolt size for future reference.
Do it again when you hit the 50 hour mark (the tightening/torquing routine) on top of your scheduled maintenance.
