Hot Hot Hydraulic Fluid 1050

I feel like a fool. I used my tractor today for approximately
1 hr before I realized that the hydraulic stop valve, the one
under the seat was closed. I was forcing fluid past the relief
valve, which is what you do if you want to heat the fluid up
quickly. The manual states that you should not keep the
valve closed for more than 3 minutes when warming up the
fluid. I had it closed for 1 hr. After she cooled down I checked
the fluid color, smell, and level, and all seems fine. Should I
change the fluid? It only has 100hrs on it. The manual says
that keeping the stop valve closed for too long can result in
a damaged pump. My loader and 3-pt hitch work well and
quickly. Thanks for your help.

Without an oil analysis you don't know how much of it's lubrication factor has broken down. A new filter and fluid is just cheap insurance.

Thanks for the advice. I changed the hydraulic fluid today,
including filter, and a thorough wash of the screen. Everything
seems to work perfectly.

Thanks,
