I have a Kubota B20 I was using a box blade on recently. After I finished with it, I loaded it one evening, kinda chilly that night as I recall, and hauled it home. It sat on my trailer for a couple of weeks before I could unload it, and when I did, the three point wouldn't lift. The loader works ok, which, as I understand it, runs off the pump in front of the engine, as does the steering. I have taken the line from the pump off and run the engine, and it seems to be putting out some flow, albeit perhaps not enough. I took the pump off the tractor and the gears look good, and the drive. I don't have a service manual, and wonder if anyone knows if there's a relief valve that could be stuck or something in the control. I find it hard to imagine the thing just quitting totally after it was working so well before. Thanks for any help or insight.

The most obvious thing to check is whether the backhoe/3pt switch (upside down L shaped) on the right hand side of the operators seat is in 3pt mode. Otherwise you are powering your non-existent backhoe 
Short of that check out:
1) Aforementioned switch linkage (goes down to oil tank)
2) 3 Pt lift height mechanism (below seat on right)
3) Pull off the 3pt lift mechanism and inspect lift piston, etc (this is a pain)
