Hello...and...congratulations! The 1850's, especially the diesels, are very durable machines. On the back of the PTO housing, there are two pipe plugs. They may require the use of a hex/allen wrench to remove. With the tractor parked on level ground, the 80W90 gear oil for the transmission should be between the lower and upper plugs. Full to the upper plug level is best. You might want to check for milky/white oil in the final drive, indicating water contamination. There are two final drive drain plugs under the drawbar. Open the rear one, and let a little oil out to sample for metal, water, or dirt. The Oliver/White final drives are very rugged if you simply keep clean oil in them to the proper level. I hope this helps! Merlin in Rushford, MN (former Oliver/White technician)
