A193 draft link setup question

Quick question - I don't have a manual showing the 193 on a Super A with the draft link being used.

When there is no draft link, like on a regular A, I think you set the draft by selecting which hole in the hinge plate you connect the front of the drawbar to and you use a mechanical lever system to raise the low at the end of a row.

On a Super A, with the draft link, you can set it dynamically, so I'm thinking the drawbar is allowed to hinge and float at the front end of the drawbar (i.e. not pinned to the hinge plates) and you instead set draft angle with the draft link and hydraulics. In this scenario, when the plower is in use, I'm assuming the rockshaft is left set low so that the draft link does not risk putting tension on the lift chain (?)

What I don't get, is how do you lift the plow at the end of a row? Do you use the draft link to push the front of the plow tongue down, or do you still use the rockshaft to lift the back? If you use the rear rockshaft and the lift chain to raise the plow, would you not be putting tons of pull force onto the draft link (i.e. tensioning it until something breaks)? I know the tongue plate is hinged, but not sure of allowable travel.

I guess the same consideration could be made for the mechanical lift on an A, but it would strain the hinge plates and drawbar.

Or am I missing something here?

The SA uses the hy rockshaft to raise and lower the plow and the lever that mounts on the bell housing sets the depth same lever sets the depth on the 192 for the A. There is a lever mounted on drivers platform that raises and lower plow unless you have the pneumatic lift system. So the plows are somewhat different for the SA and A. They are not interchangeable.

This is NOT my photo, but it IS a photo of the Super A draft link. I think this one is a report, I have a rusty original I'm cleaning up.



This is not a lever mounted to a bell housing as you describe - that is for the plain "A" as I recall.

I have the plow (an A193), the draft link, and the eyebolt the link attached to on the drawbar.

I *think* the draft link is only working in tension to force the plow down into the soil and the rockshaft lifts the back at row ends, relying on the tongue being hinged.

Anyone know if that is right?
