Thanks for all the responses.
I fixed the hydraulics (for now) and limped through the summer with my David Brown. There are still leaks at each hydraulic ram for the bucket and also at some of the connections, but I add a little fluid every few weeks for now. The 3-point hitch also works now.
I did go to a local New Holland dealer and he also carries Kioti. There was a nice 4WD model with a bucket for about $16K.
Next spring will be the time to look at new tractors (and newer used ones)as I still want something more reliable and newer.
