I have a headache from reading a lot of stuff stored in the archives! I DO NOT want to start a controversy again. So, here goes......1952 Ford 8N. I had the pump refurbished five years ago and new fluid added. I have used the tractor regularly since then...and the lift. When it was first done the hydraulics would hold an implement up for a very long time. Now, five years later, the implements will drop over a period of time shorter than at first. I am wondering if I should drain and replace the fluid? Fluid appears clear on the dipstick.
So, I live in a climate which gets cold in winter but I seldom use the tractor in winter. After all my reading....gasp.....I am thinking to buy five gallons of 75W90 or 80W90 gear oil. I was considering using synthetic grade oil but once I did the math I gave up on that idea! Thoughts?
I do most of my work in spring...summer...fall seasons. Lifting very heavy discs, bush-hog and cultivator. David
