The powershift runs off the main pump, it just has a big flow divider in it, but the part divided to the power steering also goes to the powershift, and the powersteering is fine. Also, it has been the exact same way for the past 4 years I have owned the tractor, just got a fresh fluid and filter change, which also included cleaning the strainer, and nothing changes. If I shift back to 2nd, then to 3rd pretty quickly (in neutral or a low gear... not road gear) it shifts what I would think is normally. The thing is the pressure just dropps off in that circuit when I shift and leaves the whole transmission hanging with no pressure for a split second, then all of a sudden it gets pressure back and works. That's why I was thinking it was a sticking valve, because that is what I saw when I hooked a pressure gauge to the powershift test port. It's not a lack of flow, because then if I cut the wheel very quickly (remember, steering is on the same circuit), the pressure remains constant in any gear range, PTO engaged or disengaged. My guess was a hanging 3rd gear spool, modulating spool, or pressure control spool. I'm not completely ruling out faulty seals in the powershift, but it just doesn't seam likely enough for me to not try something else first, like running a cleaning agent in the transmission to try to clean any gunk out of the powershift valve body.

To the newcomer planning to restore the machine, this means you have everything you need for the moment (something to sit in the shop and just look at for awhile while you read the books). To the newcomer that wants to get out and use the machine for field work, you may have already hit a major roadblock. That is the dreaded "proprietary hitch". With the exception of the
