Drain and Replace Fluid in hydraulic shuttle

[KubotaL185DT]

Is there any tricks to shorten the time to warm up the hydraulic fluids on a M5140 with hydraulic shuttle tranny?

Is there a problem?

What fluid do you have?

With Bulldog on this one... What's happening or not happening with it?

If you're just draining & refilling, and warming the fluid to make it go a little faster, use the loader valve to dead-head pressure for a few seconds, and it'll warm the oil faster. I never do it as it's hard on the pump done for any length of time; with super UDT and even regular UDT, I'll loosen the hydraulic filter with a bucket under it, let it drain out, then go under the tractor and do the rest. Doesn't take long. BUT if the wrong fluid is used (cheap TSC stuff for example), it can take forever to get the fluid flowing....which can also lead to weak/no hydraulic functions until the tractor's been run a little bit.
