FarmPro 2425 Fluids and owners manual

Didn’t Northern Tools sell these originally? If so they can probably get you a manual.

Which engine can only be answered by looking at the tag on the engine. Post a picture and we can figure that out.

Oil filter is dependent on which engine. Yes, more than likely there is a domestic equivalent. I use Fram 3600 on my Jinma 284 with a Y385 engine (2006). Buy them at Walmart.

Diesel engines make the oil look black in just a few hours of use. This is normal and can not be used as a “need to change” indicator. Hours and type of use are the easiest methods. An oil analysis is the only true way to know when your oil is used up. Unfortunately they cost about the same as an oil change so….

I have posted the owners manual and other stuff for my tractor here:

If nothing else it will give you a starting point.

There are times when the same engine brand and model uses two different filters. These differences have been limited to thread size, type, and projection. One uses a SAE thread and the other uses a metric thread. High projection and built in by-pass valve is preferred. The O-ring diameter size is the same. The best way is to take your filter in to a KNOWLEDGEABLE parts house that isn’t full of slack jawed computer geeks for an actual side-by-side comparison and match up.

What Piper said about the oil is true. Oil rated for diesel engines is formulated to keep soot and other combustion byproducts in suspension. Look for an oil that has API classifications of CH-4, CI-4, CJ-4, or CK-4. Most people use oils like Chevron Delo 400 15w-40, or Shell Rotella 15w-40. Another advantage of spectrographic lube oil analysis is that it can tell you which component of the engine is having accelerated wear, or fuel dilution from dribbling injectors, or coolant contamination from bad gaskets or cracked liners/heads. With moderate tractor use, I recommend an analysis every 18 months. Costs average about $25.
