Farmwithjunk gave you some great advice, however, if you block the right side tires when adjusting, you will be way off. You need to block the left side tires which tilts your tractor to the right.
With that said, there is one way to adjust a plow and that is while plowing!!! Left and right tilt of the plow keeps all three plowing the same. Front to rear tilt makes the plow tend to cut deeper or come out of the ground.
The lever moves the plow right to left to get the proper width cut depending on how your furrow tires are set. That adjustment makes it possible to get this plow to use it's maximum width cut with a large variety of tractors. To know when you have it right is by setting the plow in the ground, in operation, then stop and get off the tractor. Standing behind the plow looking toward the tractor see if the front plow is cutting a full width cut. You may have to move the dirt off the moldboard to see this. If the right/tail end of the plow lathe is sticking out into the previous furrow, you need to move the plow to the left. If the right/tail end of the plow lathe is to the left of the last furrow edge you need to move the plow to the right. My Dad always looked at this closely. His theory was after plowing all day, cutting less than a full cut, how many more trips thru the field did it cost him to get the job done??
I am not familiar with your tractor. Most CUTs do not have draft control. Sounds like maybe yours doesn't either?? Without draft control you are going to face the problem you are describing unless plowing on flat ground. Very hard to plow without draft control. Not saying it's impossible, just saying you are going to have to be the draft control and constantly be adjusting the lever over uneven ground.
A finely tuned plow is a classical thing to watch. It will enter the ground to maximum depth within three feet of letting it down. It will glide thru the field without jerky movement up and down. After plowing several passes, it will become impossible to tell where you drove. All of the plowed rows of soil will be even in size. If your plow is too far to the left there will be a gap between the row of turned soil produced by the first plow and the row produced by the tail plow from the previous round. If your plow is too far to the right, the rows will all contact each other but the row produced by the first plow will be smaller because it isn't taking a full cut.
When I was a kid I won several plowing contests with a Ford 641 Workmaster tractor and a 3-14 Dearborn plow. Made my Dad proud. Made the Farmall, Oliver, Allis-Chalmers, John Deere neighbors jealous.
