The amount of clearance is determined by the bearing position in the slot and the balance of the 3 pt interface part of the frame.
To get maximum clearance, you need to have the lock lever flipped over before you start lifting so that it will lock the bearing in the far right (facing the mower from the tractor) position. That forces lifting action as soon as you start lifting. Not much, but it helps....any helps.
Same for the leveling box being used correctly on the tractor's 3 pt arms to get them and the mower interface level.
That's why I like the cylinder. You don't need to flip the lock lever. As you start lifting the bearing will roll over to the left side of the slot and then the unit will start rising. Once at the full up position, you retrieve the piston which raises the outer portion . The edge of the inside drum is still very close to the ground but it's pretty much in line with the tractor tire so it doesn't make that much difference.
Other thing on height is keeping your front end, especially left front looking forward from the seat, on the ground. I sometimes load my FEL bucket with gravel to help when operating in rough terrain. Remembering the drums sit on the ground while mowing so there is very little 3 pt weight to carry. It's when you lift the unit you get the problem. It's a 3 dimensional thing: Feet of distance to the end of the mower, pounds for the dead weight of the unit..mine weighs about 900# as I recall, and angle being perpendicular to the tractor making the left front tire to get light.
With the bar the outside touches first. then as you continue to lower the 3 pt the inner drum will land.
I'm no expert but I have learned a few things over the years with it. My main problem is that I, like a lot of other folks, hay once or twice per year and about the time I remember what I needed to do, I'm finished for the year.
The drums and support structures are really rugged. I don't worry about bending anything when operating the cutter.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
