There's a little stubby splinedshaft coming through the front of the plate that I assume used to hold a knob with which to divert hydraulics to the rear fitting rather than the 3 pt lift. Its about 5/16 diameter and closely resembles the sort of shaft that is used for old- fashioned water faucets. I looked in my FO-20 but all it shows are the aux hyds that have their own spool valves, which this is not. Can someone tell me (1) what sort of knob or lever gets fitted to the shaft? A pic would be great (2) can soemone confirm/tell me the method of operation? I *assumed* its a diverter to choose between 3 pt and rear hyds, for trailer plows and discs, but again, I don;t know and the FO-20 isn;thelpful. thanks in advance, Bill [Reply]   [No Email]

It does just what you say, diverts the hyds from the three point to a port and locks the three point in postion. The quadrant control is used to operate a one way cylinder. Here is one Soundguy posted some time back. There are several types and it may not look exactly the same. [Reply]  [No Email]

Such valves divert oil from the hydraulic lift to a remote cylinder in an either/or fashihon. Most llikely the original Bakelite knob has deteriorited and broken off leiving only the molded in sleeve. The sleeve may be brass. If so, it will be a simple matter to carefully grind nearly to the threads in order to split it for removal. It is unlikely that you can simply thread it off without disassembling the valve so as to securely hold the spool. A useable replacement knob should be readily available at a good hardware store.
