Thanks for your response. This has seep rate dipstick for the hydraulic fluid. So I guess it's the ta30. I just got it back from a job and had a complaint of it takes 20 seconds before it will move when it's cold. It appears someone has put red transmission fluid in it. I didn't think that was right. I do have some traveller universal tractor trans/hydraulic fluid. Will that do the trick? It is approved for wet brake. I have a few Yale glc moles that require it.

That will depend on if I has the TA-30 Trans axle or if it's hydrostatic drives....the hydrostatic uses oil from the hydraulic system....the TA-30 uses Clark Part # 2776236 which I believe is 30 weight tractor oil
