Got a 375 horse versatile four wheel drive tractor with synchromesh transmission. Says in manual hydraulic and transmission fluid to use Esso hydraul 56, shell donax td, Texaco tdh, amoco 2016, or Exxon Mobil 424. Most of those I’ve never heard of and the ones I have I don’t see often in my area. Question is can I substitute those with something else? I have used in other equipment and or have access to the Cam2 AG-20 from rural king, Case IH hy-tran, and the John Deere hy-gard. Would any of those work and can any of those be added to and mixed with whatever happens to currently be in the tractor from previous owners?
