Kubota B7200 Hydraulic questions

[RedDirtSurviving]

So, I have a questions on my tractor. It's a B7200 with a 3 point hitch with PTO it also has a front bucket on it. When it runs for a period of time it starts dumping oil out of the "overflow" from the valve cover on the motor.
With that in mind, it never seems to need oil...so my thought is maybe hydraulic fluid is bleeding into the engine??

The other question is I have no visible Hydraulic leaks on the tractor, however, if I am using the tractor the rear hydraulics bleed off and won't stay set. I turn the knob to adjust the hydraulic speed for the rear and it will stay set, but if I move the front bucket it drops it all the way down and is kinda a pain to get it to lift again.

So My question on this second part is if I take off the lever where the rear lifts up and down and try and replace any seals will that solve it?

I am a pretty good mechanic however I'm new with tractors. Any help is greatly appreciated.

Do you have to add hydraulic oil?

Are the oil passages from the top to the sump open?

Yes it looses hydraulic fluid. Pretty fast but not from hoses or from connectors in the hydraulic ststem

I used to have a B7200 and it did the same thing turned out to be a seal on the hydraulic pump. I tried replacing just the seal but ended up replacing the pump. I don't remember why the seal didn't work but after replacing the pump out was fine.

Thanks Jim. Hope it's not the pump. Between vehicles n this they leave me broke.

I will look into the seals. If I can find it I will replace all the seals in it not just one.
