Hello, I have a JD GX75, have had it for over 10 years, they are a very good machine if properly maintained. Now, as to the oil filter, I have the complete owner's & repair manual for the JD GX75, nowhere is an oil filter mentioned. Now, there may have been an add-on setup for an oil filter but I am not aware of this. I just use Mobil 1 10W-30 synthetic & change once a year, never had any problems. If I am wrong on this, someone let me know. :thumbsup::thumbsup:
Actually, after reading through the Specifications, it stated "oil filter N/A" so we know now, there is no oil filter for the JD GX75.
