LS 5030 3 POINT FULL UP POSITION

[Sweetcreek]

OUR 5030 suddenly went to full up position and will not lower.
Speed valve is open , position & draft & quick lift are in lowest position .
also the hydraulic pump is under load .
If you remove the speed valve the oil squirts out the three point drops .
Desperately hoping not to remove the entire unit off the pumpkin , any ideas gentlemen ?

Hopefully this will save somebody a lot of work/money .
As you face the tractor there is a relief valve on the left side of the hydraulic unit .it. Is about 4 inches back
From the front of the unit and down on the side about 2 inches
The speed valve for the 3 point drop goes straight into the front of the hydraulic unit
You most remove the seat or the left rear tire .
You disconnect the linkage for the 3 point position & draft height
It takes a 22mm socket to remove the valve it is about 1 3/4 long , new relief valve is about $60.00
If you know this its a 4 hr job , if not tear the entire unit of the pumpkin ,towmotor and 3 men &40 hrs
