[Farmall] International 460 Utility

[Bob Currie]

In a conversation the other day, I talked with a mechanic who advises that 
HY-Tran and other hydraulic fluids are not measured in "weight" anymore, but 
instead to look for the ISO number. i.e., ISO30 or ISO64. I haven't seen 
that on any of the hydraulic fluid containers I have around here such as 
NAPA, or Kubota brands..Anybody know about ISO??
