Tractor must be running when you uncork the fill plug and add oil. I add to bottom of threads so nothing spills when I install plug. How did you fill the filter with oil when it mounts horizontally?
How? I filled it with oil while held vertically, then fitted it to the threads and tightened it was fast as I could to minimize leakage. Thanks for the help. I'm guessing easiest way to do this solo is to unhook the seat safety switch?
You have to lift the back of the tractor about 7' in the air to make the tractor vertical. Then you can fill the filter with oil and install vertically also. I think there is a revision in the manual for that procedure!
I've always wondered if it fills the filter when you prime it through the check valve on top of the hydro assembly. I don't know if it does or not, but have never had a problem changing the fluid & filter per the manual. I just changed engine and trans oil/filter on my Grand Sierra last week. That made for an expensive oil change on a garden tractor!
I'd imagine the pint is to fill the filter, but who knows?
