Just brought 1954 mm445 with 206h-4 engine and b1w model . First off, I do not know anything about tractor. Brought it to move some dirts around. The tractor runs and drive fine, a couple leaks here there but works. Need to be educated on the transmission and differential. Questions: 1. How do I check transmission level. 2. What type of transmission do I have and where do I fill the transmission fluid? 3) what type of differential do I have and where do I check and fill the differential oil. I uploaded some pics for easier identification. Any others "thing you should know" is greatly appreciative.FYI The 3 point hitch hydraulic does not work (see pics) that is why there is a bar across the pumps. future project.
