I have a Nortrac 254. I am confused as to which oil to use in the transmission. A few people I have talked to and the tractor manual say to use 30wt oil. However others say to use gear oil 80w/90 or similar. How do I know which to use (Is 30wt oil too thin or is 80w/90 gear oil too thick??) I do have some noise in the transmission when the creaper gear is in high range. Any help would be very appreciated.
Thanks,
