Plow Experts: Rollover Question

[nspec]

Those rollover plows amaze me - especially the big ones. One thing I've never really figured out is how does the angle get adjusted so that it accomodates one wheel and then the other down in the furrow? In other words, how is it that the lift arms on the 3pt hitch can keep the plow flat no matter which wheel is in the furrow? There is obviously something other than the 3pt linkage to make this adjustment. Any insight?

For those who have no idea what I'm talking about, on a normal one way plow, the right lift arm on the 3 pt. hitch is usually cranked up higher than the left side arm so the plow runs flat and level when the tractors right wheel in down in the previously plowed furrow. A lot of plows actually have their links offset - one side lower than the other for this reason. You can see it in the attached picture.

Please note! That picture is of my plow when I first got it home. It is wrong in that picture. The drawbar should be set up just the opposite. The side that goes on the right hand lift arm should be down, not up. This is so the plow will level somewhat on it's own, and your lift arms can stay more or less even. Also, the coulter arm is backwards if anybody else has sharp eyes!

I'm no expert but...

All plows, set up properly, will have the lift arms level (mostly) with the tractor.
On a one way like yours, the hitch on the plow is offset one side higher than the other to let the plow run level relative to the ground with the tires of the tractor in the forrow.

A rollover has stops that are adjustable, there is one for each side of the plow and they control how far the plow rolls in each direction when it is flipped over.

The lift arms, once again, should be level with the tractor when using a rollover plow. The "cant" is established with the stops, not the lift arms.





edit:
I really should put a better picture of my plow here

Okay, that answers my question. The adjustable stops on each side...makes perfect sense. As to the one ways like mine, the offset of the hitch helps some, but as you rotate the hitch, it will affect how the plow tracks. I set up the hitch so she tracks straight then I get it level with the lift arm.

And that is correct.

At least you have a plow that has the adjustment capability in the plow. Many of the cheap plows being sold now do not have that "crank" type hitch but only fixed pins.
A well-adjusted plow will make plowing fun.

this is my turn over old plow
I go back this use because they are so good plow
Here you can see that everything is controllable
everything with the bolts and nuts are adjustable
ok the repair is needed to plow blades
the for small cutters blades have hit some rocks
