Service tech for massy im sure would indeed make it more dramatic than it should be. We are certainly not the only ones with the thought process. When i order fluids from my salesman he never asks how many hours are on my machine. I would think they would ask to keep track but they don't. I did ask him how Massey was when dealing with a warranty issue. Of course he gave them a thumbs up but i have seen some threads on here where warranty work was declined. Of course in those cases there is always two sides to the story. Was the operator abusing the machine with out knowing he was. Or was it due to a simple failure.

A UOA Lab will tell you when it is time to change lubricants, gear oils, engine oils and coolants.

Very few tractors require a change of the hydraulic fluid at 50 hours, because it is not necessary. Filters, yes, but not fluid. Some people feel better doing it, which is fine. I absolutely would not criticize anyone who follows the proper procedure and only changes filters at 50 hours.
The other option, if you really want to examine the fluid and or access screens or other parts, is to do what most equipment shops would do during a repair -- drain the fluid into clean pails, then reuse it. You can buy very inexpensive (25 cents or less) cone filters that will filter the fluid as you put it back in the tractor. If the fluid has low hours on it (most don't require replacement until 300-400 hours) then it's a true waste to dispose of it.

I suspect that most equipment manufacturers recommend changing fluids at earlier than needed intervals to avoid warranty issues as well as generate revenue for the dealer.
Ask yourself, "What wears out in tractor hydraulic fluid"?
That depends on many factors such as the fluid itself (the blend), the severity of service, age of the fluid, moisture, shear and other factors. The fluid is there mostly to lubricate pump and gearbox parts, provide cooling and corrosion inhibition as well as provide the hydraulic pressure and flow to move the elements in the system (cylinders, hydraulic motors, etc.).
There are no combustion by-products as in engine oil therefore, the TBN and NOACK remain stable for long periods. If you are concerned about the wear of the parts contacted by the fluid, send a sample to a lab for a UOA. That's the only way to tell if your fluid is worn out, if there is abnormal wear or your filtration is inadequate.
