I wonder if Blackstone can analyze my tractor fluid and determine if it needs changing or not. I am using Kubota super UDT. Fluid looks clean and clear after 300hrs.
I/we (collectively all parties involved with tractors) typically change tractor hydraulic fluid every 2,500 hours.
Just keep it clean, and don't abuse the equipment - and the oil almost lasts forever.
I'm talking equipment that gets run for well over 10,000 hours or more during ownership.
I doubt you will EVER wear out your oil!!!!
