hi, does anyone know the hydraulics on the DB 880, friend of mine has acquired one of these machines, the problem is the 3 pt. linkage arms don't go down it has a front loader which works he as tried pushing& pulling every leaver with no result, I have had a couple of earlier fords i.e. 3000 & dexta these tractors have a button that you push in or pull out which allows the front loader or back linkage to operate depending which you are using has the db 880 got something like this or a lever which does the same thing, there is a lever to the left of the drivers seat that seams to go to the left/middle or right (3 settings) what does this do??, is it anything to do with the problem??, any help with this that I can pass to him will be appreciated. Thanks in advance.
