[QUOTE="Exfarmer, post: 5365084, member: 1951"] Right this is a later selectamatic tractor . It has the 3 way hydraulic valve plainly showing to the left side and below the seat. This will send oil either to the Linkage , trailer coupling, or loader or combination linkage and trailer. If my memory is correct that lever needs to be towards the centre of the tractor to operate the rear links. Put to the far left should work the loader. There is a 3 way selectamatic control behind the main quadrant. With the main quadrant lever pulled fully back, you can alter this to go into either draft control, hieght control or TCU / constant pumping. This position is the correct place for operating the loader. The quadrant lever should have a hook to latch itback in this position for loader work. To release the linkage you need to bring the 3 way valve across to the linkage position, then pull the quadrant lever right back. This should raise the linkage slightly removing pressure on the locking mechanism to enable that to be unlocked. The loader control spool has been added to make operation of the loader easier than using the quadrant lever, it may also have a second spool for hydraulic attachment, and crowding and emptying the bucket Hope this is clear. Howeverit may be that you have no oil being pumped at all in which case the problem is far more complex [/QUOTE]
