JD 4105 third function loader not working-

[tassiedevil]

Hi all, I have just re attached my loader after some months and for some reason the 3rd function is not opening the bucket- is there a fuse for this function or is is it purely a hydraulics problem maybe?
I must admit the tractor doesn't get allot of attention these days but it would be good to find out if this is a straight forward problem.
Thanks in advance.

Check for voltage at the solenoid first while activating the button. But ,I suspect the spool in the valve body is stuck from lack of use, not an uncommon problem. Post some pics of it and we can try to help.

G'day Cobber!

I've had a similar (or, perhaps, the same problem) with my 4105's FEL 3rd function.

If your 4105 is from "Midland Tractors", the 3rd function is an 'in house' addition. My neighbour was able to hunt down the fault and it turned out to be the valve in the block not seating.

My 3rd function fault has since returned. I, like you, am in no hurry to have it corrected as I rarely use my 4in1 bucket.
