There are some downloads for your tractor in the Resource Manager (sic) section:Hi all, I have an IH 574, diesel. Pretty basic question but this is my first tractor. How much hydraulic fluid goes in the back? I can see some gears and such when I open the fill location, should these be completely submerged? I usually fill until the dipstick reads full, but just checking. I have never drained the system and replaced it. I have a couple small leaks from the loader and power steering so I end up having to refill it every now and then.
Also, it does make a whining noise sometimes - is that a filter problem usually?
Thanks
Zach
