Thank you for allowing me to join the group. I've read many posts over the years but haven't joined until tonight. I hope that everyone is having a great weekend!
I recently purchased a 3720 from a friend of mine. That tractor has sat outside for all of it's life. The lift and lower function for the FEL work fine. But the left to right movement of the joystick for the curl function is very stiff. Like it almost took two arms to move it. It would function though, just very very hard to move.
I took off the seat and blew that area by the manifold out with some air pressure and then hit it lightly with a pressure washer. Then I tried to spray some Fluid Film where I could get it, but it's pretty tight access and I can't see much.
At this point, it definitely has freed up tremendously. It's just about as easy to move side to side as it is up and down, but not quite.
The problem is that although the movement is freed up significantly, it doesn't ever return to center when it's released, from either side. I was hoping that since it was out in the weather for so many years that cleaning and lubing it up would solve that problem. And it has made it much better, but still doesn't return to center....would this point to something internal instead?
Hydraulics are not really my strength.
I have been doing all of this without the tractor running, by the way, just exercising the joystick while it's parked.
Thanks for any input/info and for the membership to the forum.
