Water/condensation contamination from sitting under a shed for 20 years was kind of unsettling to me. I pulled the rear cover and wasn’t quite prepared to see what ran out. I’ll attempt a video here. I raised the front, let it drain, wiped then rinsed it out before changing the filter and refilling it. There was no apparent rust/corrosion in the rear end. I had a 5 gallon bucket of JD HY-GARD so I used that considering I’ll do another fluid change. It apparently has never been changed before. The OEM filter has a number on it that I’ll assume to be a date of manufacture. Have you folks seen fluid contamination to this degree before?
