I noticed my 175 is very jumpy using hydraulics, lift, loader . It is a little low i checked , but here is the question. Setting on tractor, top of the lift resevoir there is an elbow. When I use the loader or lift it wants to puke a little out and runs downs housing. What is likely cause. What type of hyd fluid -trans are you using. Hasn't been changed lately. Does Oreillys stuff pass the test? Also with a FEL, how much more fluid do you top off with? Thanks, Tracy

What is your chassis s/n ??? because yours may be the later model version and that is the breather for the hydraulic system. Like directly under the battery area ??

Dr Allis, it is directly under battery placement. I can't remember the serial number, but is a late model with wishbone frontend. It does have the little tube underneath that ies the two compartments together. Thanks, Tracy

That's late model and that is the breather. Your hyd dipstick is sealed and NOT the breather on yours.
