OIL Confused (B7200 4WD +Gears)

[irish]

Hi all. Bought a B7200 4wd with gears 10 days ago -first tactor.
After hours of reading through the forums (or is it fora?) I decided to check the coolant, engine and transmission oils. Engine oil level fine and coolant fine. Transmission oil just barely registers at the very tip of the dip-stick, so it is low, I think. The 3 point link lift and pto appear to work ok. I'm not yet confident enough to do a transmission change and filter change but would love to try out the tractor as soon as possible. I asked a number of "experts" what fluid I should use to top up the transmission, including a guy at my local Kubota agent.

Each one suggested the use of a different oil, including (i)10W30 transmission oil (ii) 80W90gear oil, (iii) Kubota transmission oil, [-which was out of stock in Kubota!] and (iv) any light transmission oil from the local motor store.

Question: As I do not know what oil is in ther at present, which should I use to Top-Up the existing low level and secondly could I damage the transmission if I mix the oils by adding a different one to what is in there already?
Absolutely brilliant Website! Keep her revin'.....

A manual should have been included with the tractor. If not, I think that one can be purchased from Kubota. Use whatever the manual recommends.

With the fluid being that low and without an obvious leak the trans oil is probably due for a change.

Messicks website has the information and a manual. They sell both the 80w-90 gear oil and Kubota SUDT (probably for the HST model). However, the gear oil may only be for the front differential. Get the manual first. A call to them to ask may also be an option.

The tutorial below indicates that SUDT is used in a B7800. But check first to make sure.

This is where I go to look up Kubota information. Some take gear oil for the transmission and hydraulics, some take hydraulic oil. It looks like yours takes hydraulic oil, but check it out in case I put in the wrong info.

Thanks RDR. Very heplful.

I think I'm gonna have to get brave and change the fluid rather than risk the "mix."

Vic, A "Lubricants hot button" would be great for novices like me!
