As mentioned I have the tractor running engine and over/under wise and all seems to be ok.
However there was a leak from the right brake at the drain hole in the bottom of the housing. I expected to have to replace the O-Rings even though I had done it before and thought something had not sealed properly. However when I took the brake assembly off completely and sprayed it out with brake cleaner I noted that the seal was leaking around the shaft the brake disks are splined to. Hmmm not so easy a fix.

Also for some reason the hydraulic oil keeps dropping in the tank. I decided to check the transmission oil level by removing the upper plug. Oil shot out of this when I loosened it. It appeared thin like hydraulic oil and not 90W as I understand is supposed to be used in the transmission. I guessing this is where the hydraulic oil is going.

Now the question. How can it get into the transmission? By the hydraulic pump if a seal is leaking or can it get from the reservoir which holds the hydraulic oil?
Also since the oil level appears to be too high if it is supposed to be higher at this upper plug level will it still require a seal change once I drain it and find and repair the leak? If so what is the best way to replace this seal?
