I just bought my first tractor, its a 2640 with ~2800 hrs. It runs really good and everything works right now. Also has an aftermarket loader that works great and no hydraulic leaks or any other leaks ive seen.
Downside is I know nothing about tractor maintenance!! I'm decent with trucks but I have no idea when to change fluids/filters etc. on this thing or which fluids to use. I've ordered the owners manual so I'm sure that will help. But if you guys have some pro tips that you would like to share let me know!
