1964 135 gas

I just acquired this tractor from my mother-in-law. Can
someone tell me how this valve operates? The handle is more
sing but it appears to be a two-position lever.

It appears to be a diverter valve or isolator valve. There should be a handle in the outer hole so you can rotate the shaft. The 3 point hitch operates in one position and the oil comes out of one of those elbows in the other position.

It's a diverter valve.

Yes the handle is missing. Not sure what he used it for, since he didn?t have anything hydraulic, just a plow, disc, and bush hog. So it would be sufficient for supply to a loader? I have a two spool valve on a 150 that I can swap out. I just bought a trip-bucket Freeman loader for the 135, it?s all going to be a winter project. Like most 135?s the nose is pretty used up, but it runs like a top, no oil leaks.

The 3 point hydraulic pump put's out about 4.5 gpm (gallons per minute), it will work a loader but it will work slow. If you are no hurry to do jobs you are using the loader for it will be ok. A front end loader works good (fast) when you have 12 gpm or more of pump flow.

As been mentioned that is a divertor valve the first hole in the shaft closest to the block is suppose to have a roll pin that hits the pins on either side and acts like a stop. There should also be a roll pin on the end to provide leverage to turn the shaft. Turned one way it provides oil flow to three point hitch turned the other way provides a oil feed and return to a aux eg loader when the transit is moved into constant pumping.

CAUTION: Do not move the transit into constant pumping when divertor valve is in the three point hitch position as there is no relief and over pressurization could damage pump.

You will want to use a open center control valve for your loader. This way in constant pumping and no actuation of control valve the oil will flow through the control valve and back to tank until the control valve lever is activated.

I inherited my fathers 135 and mounted a mf200 series loader onto it that I picked up at a farm auction. I realize its a heavy loader for the light front axle but it only clears snow and does small amounts of light duty work. As mentioned the factory pump does work but is a little slow. On the other end speed can break things so I don't mind slow gives more control.
