Just become the proud owner of a B20 (upgrading my old iseki TX1300) and it has a little leak. It appears to be coming from the drive shaft seal into the gearbox. Not knowing much about these machine yet i am assuming it is transmission oil (that i believe is also the hydraulic oil on this?). Its only a small leak and i am tempted to leave it for a while whilst i get used to using the machine and i assume its a "split the tractor" job. The machine will only get low hours from now on as i am taking to my land in Slovakia where i only get to visit a few times a year. Am i taking a big risk here of the seal exploding on me a loosing all oil or will it just drip for years.

If i do have to split the tractor, is there anything else i should change at the same time such as clutch?


Any advice would be appreciated.

thanks

Yes most likely I will just drip for some time, they normally will not just cut loose, but it will get worse with time. Put a drip pan under it and keep an eye on the hydraulic levels till you can get it fixed.
If you split the tractor it is a good time for a clutch job and an evaluation of other parts and seals in the area.

thanks for the advice, as i am taking this to slovakia soon, i was intending to get the work done out there. The labor rate is far cheaper than in the UK and they seem to have a a decent Kubota network there. I will run it for a while a watch the oil levels
