[QUOTE="Exfarmer, post: 5011858, member: 1951"] If it has not been used for years and the linkage lock is engaged it is probably siezed. Be careful trying to shift it, as the lever easily breaks if force is used. The linkage lock must only ever be disengaged if the linkage is at the top. If there is no weight on the links when the lock is free you will be able to diengage it by lifting the links to the top by hand and then turning the lock with the. Other. Other questions, does the linkage move at all when the quadrant lever is pulled right back? Has the tractor got a 3 way valve chest, which sits behind the drivers left heel? This can be of 2 types, the early ones had 3 knobs which you have to open or close depending which service you want, linkage, trailer tip, or loader. The later, a 4 position lever. These were linkage, loader, trailer or trailer and linkage. Not nessesarily in that order. If this is not in the linkage position oil in the ram will stop the linkage lowering. The other lever to the rear of the quadraant on the right is to choose between draught , height or TCU / spool type work / constant pumping. Only ever turn this lever if the quadrant lever is pulled right back. More advice can be easily found On the DBTC club website. [/QUOTE]
