Hydraulics Sound funny and don't work

[astater]

Alright fellas...I'm back with another rookie question, or maybe not. I've had my TC40A for about 3-4 weeks and the hydraulics have been fine until this morning. Started her up this morning and the bucket didn't want to come up very fast at all but made it up. Then the 3pt did the same thing but both functioned. I thought maybe it was just cold or something. Ran the bush hog for about 40 minutes and then the PTO started to go in and out. Seemed to get bogged down. I'd clutch and lift it and it would start back up again but not immediately as if it were really bogged down on grass...About this same time the bucket really started struggling to move at all. Same with 3pt. I took a video of the bucket in "action". Once I activate the joystick to lift the bucket, I don't let off and you can see what happens. Dealer said it's probably low fluid or a clogged filter. Changing the filter tomorrow but the fluid is full and clean. Take a close listen to the hydraulics in the video. I'd describe it as a metallic rattling sound? What's wrong with my tractor?

Low on fluid or an air leak in the suction side

Or maybe something in the pump went south.

Do you have a U-Got-Tubed link for those of us that don't allow inline video? (Flash Player).

Auxiliary hydraulics engaged ?

Not sure what that is?

So, I replaced the hydraulics filter and everything worked flawlessly for about 5 minutes. Then back to the same thing as described above. I identified the "buzzing" or "rattling" sound and it's coming from one of the hydraulic lines coming from the joystick. Pretty sure there's something awry in there but it's above my head.

I still think it's air. Even more so after your last description about it coming from a line near the valve

That's my thought as well but like I said, I've only been a tractor owner for about a month so I'm not diving in on this one.

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!
