    My L4240 manual says to change the trans fluid at 400hrs.

    I'll ask him to cite a reference next time I'm over there. I was just passing it along, and don't necessarily believe it either.

    I believe it, although 'never' probably doesn't actually mean 'never'. I put 600 hours on my tractor before I changed the hydraulic/tranny fluid, and another 300 that the PO put on, and who knows before that - my L4200 tractor had 2600 hours when I changed it. I did change the hydro filter once before that though. The fluid that came out (which I assume was SUDT) was exactly the same color and consistency as the stuff I was putting in (Universal UDT-compatible fluid from Sam's).

    His article attempts to support my idea that oil analysis might be the way to go. Unfortunately, to get an idea of what is going on ~$75 would need to be spent on analysis. A raw sample of SUDT2 would need to be tested for a baseline, as well as various samples at different hours.

    $75? I can change the fluid out with 10 gallons of new for $85. So much for oil analysis.

    If you were to use kubota SUDT2, it would cost ~$250 to chance the oil in the L45.

    Why buy a $40k machine and cheap out $200 on the hydraulic fluid?
