Hydraulic Problems 806 Farmall 

I just used a shop vacuum. Used the small hose and placed it over the dipstick tube.

I have never used a vacuum to change mine I never lost any more oil than you did. There are enough of those old tractors around you could get the newer cover and that makes it easier to change the filter

@@warrenpost1502 Same. That section doesn't drain out the reservoir when the engine isn't running. What does the newer style cover do?

The gasket came with my filter. But on my tractor I definitely needed the RTV silicone to seal it up
