I think your tractor is gear drive (not hydrostatic drive) so the Traveller or plain Kubota UDT is fine. There is no need to get into synthetic transmission fluid for gear drive tractors.

UTTF stands for Universal Tractor Transmission Fluid.

There is at least one drain on the bottom of the transmission. There may be a drain plug low on the rear wheel drive on the tractor that also need to be drained. I am not sure your tractor has them but you can look.

This is a diagram from my tractor that shows where they are (sort of). I highlighted the plug and sealing washer in yellow. They screw into the inner wall about where I marked the outer wall with a red mark. You can see them by laying on the ground between the rear wheels and looking towards the area outside of the tractor rear wheels. (Hope that makes sense)

Mine is gear driven. And 4x4. Same fluid for the front axle or different?
Thanks for your time, and information.
I’m clearing a space in an already full garage to remove the donor loader then roll in my ZB and then the real fun starts. I’ll post pics and I’m sure need more insight Merry Christmas 🙏👍

You can use the same fluid in the front axle or use 80w/90 gear oil in the front axle.

UDT is what's supposed to be used.

Mystik JT-5 is a good fluid to use.
