Hydraulics Sound funny and don't work

[LD1]

How is the hydraulics doing now?
I am not an expert in this. Hydraulics generally have these sort of issues. You should be careful while changing the oil and the filter. I also doubt air in the valve. Five Common Hydraulics Problems - Pentalift . These are 5 common hydraulics problems that can harm the hydraulics. Have you unkowingly done any one of these errors?

About the only one of those 5 that would apply to tractors is using the wrong type of oil.

#2....changing filter too often.....is not gonna cause any harm.
#3....overworking the engine......these tractors are made for 100% duty cycle. Unless you are putting a heavy PTO load on the tractor and never cleaning the radiator screen, the tractor is not gonna overheat. They are made for it
#4...Waiting for the equipment to prime.....not necessary with the design of these tractors. Start the tractor, and before your hand can make it from the key to the loader joystick.....its primed.
#5.....Not learning how to use the equipment.....Yea, there are alot of inexperienced people on tractors. But that shouldnt have anything to do with the hydraulics not working. About the only thing an operator can do to cause self-induced hydraulic issues is not getting the quick coupers seated all the way.

So, the dealer I bought it from fixed at no charge. Turns out it was the little screen that filters the hydraulics. He drained all the fluid, pulled the screen and cleaned it, then filled her back up. Ran smooth for about 2 hours last night, so it looks like it's fixed. Dealer said that's an easy fix that happens periodically but shouldn't happen again soon unless there is something getting in the fluid. There were no metal shavings or anything else on the screen, just gunk. They also confirmed the rattling sound I heard was the pump starving for fluid and sucking in air. Gone after the screen cleaning.

Thanks for the info guys!
