I have a 2001 L3710 cab HST with loader. I do a lot of everything with it. A great tractor. However I have developed what I can best describe as a severe squeak that seems to eminate from just below and to the right of my seat.. but I can't reproduce it by bouncing or moving the seat..I think it is farther down...I think sometimes it helps to hold the mid PTO lever...but honestly that might just be my imagination. I have looked to a degree under the cab and nothing is obvious...it does seem to be worse in rough pasture. Before I try to take it loose or delve deeper I wondered if any of you astute individuals could steer me in the right direction.
