I bought a used JD 950 Diesel about 6 months ago. The oil was last changed on February of 2008. The hours was also noted. Since the last oil change the tractor has 20 hours on it. However it has been over a year since the oil change. Should I change it or wait until it gets more hours? At how many hours or time should the oil be changed?
It's completley up to you but I'd probably change it just for piece of mind. Then again you have good records as it's been done. If you have work pressing and need to get it done It'd be fine IMO to run it a bit too, before changing.
