what would cause my hydrolics not to work. no bucket or brush hog will work

Welcome to the forum but it may be the wrong forum. :welcome: You might need to post on the Kubota forum. I am not familiar with Kubota hydraulics.

Just a few items that will cause hydraulics not to work. Low or no oil, stopped up filter, crack in the suction line from sump to hydraulic pump or worst case a bad pump which could entail stripped gear on the pump or just worn out. If it just suddenly stopped working and you have changed the filter and oil, then look for a crack in the suction line. Worst case is failed pump.
I suppose the relieve valve could be bypassing all the oil, but that is unlikely since you say nothing works at all. Some Kubotas have an internal screen that has to be cleaned. Best to get the schematic for your tractor and look for all the filters/screens and make sure they are all clean before doing anything else.
