If your loader works fine, the 3 point probably wont as the valves will be set for exernal. The raise/ lower lever will be clipped right back into select and the selectamatic valve will be set in TCU/external. By your left heel will be a selector valve with 4 positions L (linkage) L/1 1 & 2. Early tractors had taps. It will most likley be set on 1 or 2 IF the loader supply is taken from that valve. Set the valve to L, the Selectamatic valve then has to be in Hieght (position) or Depth (draft) position on the dial to the rear of the main raise / lower lever. Pull the raise / lower lever on the quadrant right back against the spring in to select BEFORE and while you turn the selector dial to depth or hieght. Also IF the tractor is fitted with a dump valve just behind the main lever for raise / lower make sure it is DOWN.

IF the loader supply is taken from the selectamatic valve on your right, then you will most likley have a blocked By-pass or hold valve, these are to your right under an oval plate, you may have a dump valve fitted into the hold valve, or not, they were an option.. These valves can stick. they are capped by a scew plug (slotted for a screw driver) If they are stuck they can be got out by whittleing a piece of wood to knock into the valve and turning and pulling. One of the valves has a fine filter and from memory there is a small ball bearing in there as well. With the valves removed, turn the engine with the starter with the engine stop in STOP, this will flush them with oil and remove any rubbish in there, also disassemble the valves and clean out with Diesel fuel and blow through.

The main filter is underneath and there is also a magnetic filer in with it. If your oil is milky best to do that before looking at the By-pass and hold valves because any loose debris from the filter goes straight to them.

Today's Featured Article - Madison's County - by Anthony West. Philip Madison has been a good friend of mine for quite some time. He has patiently suffered my incessant chit chat on the subject of tractors for longer than I care to remember, and on many occasions he has put himself out, dropped what ever it was he was doing, to come and lend a hand cranking handles, or loading a find onto a trailer. Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects. ... [Read Article]
