I’m sure it’s a repeat question. Changing hydrostatic fluid in my. B7200 and want opinions on what type I should use Kubota or other. brand. Don’t mind paying extra $ for kubota fluid if that’s best option ...
well......
this question HAS NEVER been asked.....OK - I am lying!!


you have a 30 year old tractor.... UDT was the oil of choice at THAT TIME......
IF you do NOT mind buying the "good" stuff - get a gallon or 4 of the S-UDT2 stuff from you local dealer or get it on line! Amsoil makes a great oil for that situation too - and it too is costly, but......
There are many other types of oils that will fit the bill of a 30 year old tractor - but the oil is the life-blood of the machine and buying the tractor supply or walmart brand might not be the best choice, even though THAT oil is probably better than the oil from day ONE.
Whatever you choose - get the original K filter and check your screen while the oil is out - might find a mess there on that screen/filter.
