Looking for some advice from all of you seasoned owners out there. I'm coming up on 50 hours now on a 2014 BX25D. What are the must-do items vs. the items that are nice to do but not critical to the health of my tractor? What brand names for fluids (oil/hydro) do you suggest while controlling costs? What do you suggest with regard to grease fittings (type of grease, etc)? Do you have an online source for these things? Any advice? This is my first tractor, so am very open to anything that might help me do a good job, not cut the wrong corners while keeping cost under control. I have a nice shop and intend to do this myself. Thanks in advance for your thoughts.
