I just bought a HP 12-24, older restoration. I know almost NOTHING about this machine but am very interested in entering it into pulls next year.
Since I know so little, I need instruction. Can anyone help me with maintenance or tuning and operating instruction. I am a mechanics teacher but this is my first old tractor.

What engine oil? 
What transmission and final drive oil?
What amounts?
So much to learn!
