Run it up and down 3-4 times and you should be fine.

Do I need to loosen the bleeder screw or does it self bleed?

Newly installed hyd cylinders will self bleed of any trapped air during operation.

I've never seen a agricultural hydraulic cylinder that has a bleeder screw on it, I would just hook up the lines to it and run it up and down to the end of its stroke in each direction, as you move the piston back and forth it will force the air out.

I’m going to guess it’s a single acting cylinder, and he is calling port that is plugged with a air orifice a bleed screw.

Good point, running it up and down (without depth stops) should flush the air out.

not real clear on the terminology but its the silver hex screw at the top of the cylinder, it has a weep hole in it where the fluid sprayed out which is what led to me replacing the cylinder.

That side is normally full of air, it fills the other side with hydraulic fluid to lift the mower.
Take those depth stops off, lower the mower all the way down, then raise it all the way up a couple of times.

sounds good and easy enough. Thanks everyone for the feedback.
