[AT] I need help on 3 pt

[Clint D]

Larry

Thanks for your reply, I went this evening, pulled the pump and checked everything
from the pump back to the loader bucket control valve and really did not find
anything unusual or suspect.

QUESTION,  I have not checked anything from the filter back to the rear end where
the 3 pt control is, is there supposed to be any relief valves back there? I have
not seen any evidence of any so far?
I have never done any work around a 3 pt valve, so this is new to me.

What type of areas should a relief valve be for me to check out besides at the
control valve?

this thing has me totally stumped.

Another question, normally on a tractor like this, is there anything inside the
trans. compartments in front of the final drive/rear end that could effect this? I
cannot think of anything myself, but just pulling things from  thin air right now
trying to get this figured out

Clint
